Breakthrough Starshot - Nanocraft to Alpha Centauri
HTML-код
- Опубликовано: 26 сен 2024
- Yuri Milner presented Breakthrough Starshot, a ground-based light beamer pushing nanocrafts, ultra-light space probes attached to lightsails, to speeds of up to 100 million miles an hour, which could reach Alpha Centauri in just over 20 years from launch. Together with Proxima Centauri (α Centauri C), Alpha Centauri A (α Centauri A) and Alpha Centauri B (α Centauri B) are considered a triple star system.

If they start now, I'l be alive to watch history..Do it!!
don't worry kid you can born in future just like this one how you were born. if you can born in this life time why you can't born in future so don't worry just chill.
***** 80+ aprox. Maybe i'll be here lol.
***** They need to start now! lol.
***** Yeaah the future in that matter looks awesome. Wish I could live 300 years just to see what is coming.
+Raul Luevano Humans are going to go to mars on this century
Wonderful, this project deserves a lot of funding, I'm so sad I'm not a billionare!
Work harder.
If one of the spacecraft weighed 35 grams, travelling at 1/5 the speed of light, it would have more kinetic energy than the atomic bomb detonated over Hiroshima (15 kilotons of TNT). They're talking about sending 100k+ of these probes to flyby the Alpha Centari system, that's a holocaust for an alien society.
+wyldeman0O7 best comment ever, hahahaha
Does it have the time to totally burn before hitting the ground of some planet with an atmosphere? Can it light up a gas giant?
+Armando Cavallo 1/2(59958491.6 m/s^2)*0.035 kg = 62912862511577 J or 15.036535017 kT
Gilbert Bernas I am not asking this. These crafts have no guidance at all so it will surely be impossible to land. I am asking if a planet gets in their way, will it suffer destruction??
Chances are it won't hit anything with life on it
Who will design the force field? One grain of sand at 20% light speed is destructive.
+Senju Hanashi No one, the current plan seems to be to send many, hoping few would reach the destination
+Senju Hanashi Its better to send "let's say" 1000 of them, and hope a few of them survive, rather than building such ingenius tech as force field. This will keep the craft expense at minimum, and also provide statistics about how many have collided. This way we will know what we have to deal with in the interstellar space. I also think that after reaching terminal speed, it should get rid of the sail to have bigger chance to survive.
Kinda like natural selection. Thrilling.
Senju
Are you expecting that we'll find lots of sand grains in space?
I get what you're saying, though. Maybe not sand, but there will be dust that could prove disastrous to such probes. But even if that does happen, the lack of wind resistance/ drag in space means that such collisions will clear the way for any craft/probes following the same trajectory.
@@Raz.C or make it worse and spill more flying debris into which all following satelites crash...
can we crowdfund this? I would gladly contribute some of my salary if it meant getting photos of those planets in MY LIFETIME
Already testing initial prototypes in space ruclips.net/video/sm3O15wepGI/видео.html
we looking into the future here, amazing!
how the heck will it send back pictures? that thing has a WiFi hot spot too?
yeah it has antena wich we hope will point out direction and send us alliens nudes after approx 25 years from launch
@@paveldrumev2117 the message will take 4.5 years when sent from there at proxima Centauri b
aliens could have been sending us lots of postage stamps and we would never know.
real breakthrough in human history - wish all politicians keep their differences aside and unite on this topic.if there is intelligent life near alfa centauri, they will be come hunting for earthlings when they see these tiny nanocrafts in 20 years
who would see it? We wouldn't if they came past us. Too small
Kinetic energy is E=mv^2/2
1 gram at 60 000 km/sec has energy 1.8 Terajoules or 0.5 GW-hours.
To apply it within 2 minutes intensity is 15 GWatts.
Imagine 15 full scale nuclear power plants (1000 MW class) dissipating all production energy on a 1g silicon wafer for 2 minutes.
After couple nanoseconds, silicon wafer will evaporate as high energy plasma.
+Yurik The idea isn't to target it at the wafer but the sail, which would have an area of 1-2 square meters, and be made of a resistant material able to stand up to the stresses. That's still far beyond our current technology, but that's why we're starting the research.
+Sushiman118 shape, size and material do not make any difference. 15 GW on 1g mass for 2 minutes, no matter of it is 1cm2 or 1m2
+Sapri Marathra plasma atoms have random direction, it's speed vector achieved during random body evaporation. After nanoseconds, all atoms will become plasma, after microseconds they will spread as dust island 1m2, and 100 m2 after milliseconds. For 119.9 seconds laser will beam vacuum
Simply fucking amazing.
this shit is fucking history ! if it realy works
Well it can work and we have the tech to do so
ye, it is just expensive and it needs more research to develop better sails, and even protect them from interstellar dust, but if they are sending thousands of these starchips, what are the odds that every single one of them gets hit my dust particles, so this is mathematically proven
Oh this will work I bet, and we may colonize Mars in the future, but most people will be dead from cancer and other diseases we "cannot cure"....
it is cureable
Suggestion: While we're perfecting the technology, practice by using it in our
solar system. Instead of the ONE flyby of the outer planets we have
now, we could make missions to the planets a routine thing.
Going to just 1% of lightspeed would get the probe to Pluto in less than a month.
But we couldnt stop the space ship, we woul need to build beams on every planet on the solar system to thavel easly with that tech
We actually can.
If we fire them on the right trajectory, then we could slow them down using smart gravity assists.
This would obiously work best in the jovian, saturian an uranian System, due to the high mass of the planets and many moons and the possiblity of aerobreaking.
In my opinion it would be best to use serval different of those small probes, each equipped with a differnt module and a little bit reaktionmass.
Sending them into polar Ortbis arround these objects, to assamble the bigger satellite there.
The usage of a polar orbit would have the advantage, that the probe would go ver every part of the object over time, allowing the usage of very narrow, yet high resulution scanners.
Todays spaceprobes only go by an object a few times, to get as much sience out of the mission as possible.
Thus using this technologie, the detailed exploration of the many moons an moonlets in the outher solarsystem could become feasonable.
@@jensbrandt7207
Travelling at light speed? No, we couldn't slow them down using gravity assists.
The best we could hope for is to deflect their trajectory ever so slightly.
If we wanted to use gravity to significantly alter the trajectory and/ or velocity of an object travelling at light speed, the gravity would need to be from a neutron star or black hole. See, an object travelling at light speed will either not spend enough time in the gravity well of a sub-stellar object to change its trajectory/ arrest its velocity. The ONLY way around such an issue is to use a gravity well of sufficient force and the only such gravity wells are around black holes or degenerate matter.
@@Raz.C You are right, I wasn't as well informed back when I wrote that comment.
Today I would suggest to go as fast as the onboard reaction mass of your slightly larger in solar system probe can slow you down, so aerobreaking becomes thermally survivable.
@@jensbrandt7207
It's good thinking, but it could only be of use while the probe is in an atmosphere. The problem with this is that it would need to slow down a LOT before making it to the atmosphere, or else it would simply burn up. The aerobreakes could only slow it down *after* it hits the atmosphere, but to prevent it from being burned up, it would need to slow down *before* it hits the atmosphere.
And the obvious problem now is that escape velocity for most gravity wells is at least 13 Km/ s. That's about 45,000 Km/ hour. If the probe is travelling at 20% of light speed, that's 20% of 300,000 Km/ s which is 60,000 Km/ s and that is 216,000 Km/ hour. So it needs to slow down from 60,000 Km/s to about 10 Km/ s. And it needs to do this before it hits the atmosphere, or it's toast.
And that's the problem of space travel. One of the problems, rather.
what is going on with the people in the panel sitting at the side of the presentation screen, their movement or lack of movement seems strange.
I think afew decades would be enough time to get these things off the ground like we did back in the 60s. I'm no scientist at all but any average person can dream and appreciate what astronomers, scientists and all other space science related issues are doing to make the impossible (possible)
Skeptical about both the capacity of the chip to accurately point towards Earth from Alpha Centauri and the capacity of Earth instruments to detect the frail signal out of the noise.
it's neat that they're thinking about this, but, if the ultimate end product is to get there to migrate there, I don't understand how this will help us physically reach that far. This kind of thing only works on such a tiny device, so I'm not sure what the plan is of what happens if it is suitable for us to live there, and we want to make the trip ourselves. It seems so far, it almost seems to me to be more practical to try to make the moon or Mars inhabitable.
Fuck, I totally forgot that Stephen had died. Man, it feels bad.
Wow, just amazing!! Only one thing I didn't understand? How a beam of light would send it back from AC??
I dont think the nano craft would come back. They would just send the information they collected in radiowaves maybe which travels at the speed of light
That's nice but how is something that small going to be able to send any data back?
Cameras on it
+hurrdurr25 radiowaves
powered by? focused by what antenna? This is 4.3 light years distance, not a couple million miles. And they've said a laser, well how is a laser running on such a tiny amount of power going to be distinguishable at that distance when right next to a star?
In 5 years we will have greater technology to get to Alpha Centauri in 10 years.
In 5 years our technology is advancing so fast!
These craft would need to get right up close to another planet to take any meaningful pictures. If you recall the best images of Pluto which existed before 2015 were just a few dozen pixels. Even images taken on approach by the New Horizons probe a few days before it arrived at Pluto in 2015 were still extremely fuzzy. And it knew where it needed to look. These will just be aimed in a very general region of space. Unless the plan is to just carpet bomb the star system with 100s of thousands of nanocrafts hoping to get 1 half decent grainy photo. This feels like a hopeless waste of money.
Maybe this technology could be used to deflect asteroids?
I imagine if one of these hit an asteroid at 20% the speed of light the asteroid would explode into tiny pieces. Or maybe just make a hole through it? I'm not sure how high speeds work.
RedsBoneStuff no shoot the lasers on asteroids not ships to an asteroid
You don't want to shoot an asteroid with lasers because now you have tons of small asteroids at the same speed coming at you. What you would want to do is find the asteroid going to hit you and send a probe to attach a sail to the asteroid, then shoot the sail and move the asteroid out of the way, or perhaps even out of the solar system. It's a very inexpensive way to stave off the earth from total annihilation.
nah. Mass of dangerous asteroids is way to much.
How will a chip so small generate power abd transmit data back home ?
Not an expert but it works the same way your phone does, don't hold me to that, not fact
What I do know for sure is the message will take years to return to us
@@jason32742
They said it had photon thrusters. That would imply a power source for the photons and presumably that same source would be used to power the camera and the transmitter. The transmission itself wouldn't be speed limited, so would only take about 4.5 years to reach us, so as soon as they launch, we only need to wait 25 years to see pictures of the surface of an exoplanet. That's something to live for!
I'm assuming the photons we direct towards it, can be stored on the chip then used as energy to send images back towards us.
What might be neat, is once all these chips GET to alpha centari, they could self assemble into the same type of array used to send them there.. then start sending some actual chips back, possibly with samples etc taken from the planet ?
if we can get these things to be robotic the potentials would be endless
What kind of apparatus would be able to receive such a weak signal from Alpha Centauri? It would have to be unbelievably sensitive. The distance and interference would be massive.
+Caio Pontes Well he said "on a beam of light" so I'm assuming he's talking about using laser communication. With the right wavelength and detectors it certainly is possible.
Or you could have one that has 2x of the power of the first one and have it just launch back at earth (maybe)
+Caio Pontes Remember that the Voyager probes were launched in 1977 and have been able to successfully transmit data from the outer solar system, continuing to operate even today.
Possibly they thought of that
***** Scientists can be very clever every now and then. Maybe they can find a way?
Once we actually reach the system and fly by, the data sent back from that time would take about 4 and 1/2 years to get back to us( at the speed of light). So, 20 years to get there (roughly) at 25% the speed of light, then 4.5 years before our our data starts arriving back on Earth. Not bad for the first trip of this kind. At 25% the speed of light the flyby on this system wouldn't take long, at that speed you could go from our sun to earth in about 32~minutes. Someone asked below how long this all takes so I hope that helps you get your head around it a bit.
Before 20 years we could get to Alpha even faster.
How would they target it with their lasers given the earth movement and the increasing distance? How will it stay stabilized?
yes its a good question
I suppose it's very possible considering the Earth's orbit and the craft's distance can be calculated. I'm somewhat more worried about unexpected events like earthquakes
I think they will target only at the beginning. Once the small craft gains maximum velocity in vacuum, there is no need for more propulsion...but I don't know.
Well, depending on how fast it will reach max speed, but yeah, there's practically no friction in space, so these thingies won't slow down.
A thing called Math.
so your saying we cam build a laser powerful enough to reach another system ?? damn talk about intergalactic weapons lol
the fucking death star
+Jayy Grimm thats what im saying
+MyLifeIn Videos Earth is now a death star!
they are just like giving it a boost ones and it keeps it energy all the way
SSSSSUUUUUPERRRR HYPPPPED! THT EARTH WILL TRUN INTO A DEATH STAR AND BECOME THE FIRST ORDER!
I wonder if solar sail craft could get a boost by traveling along the gravitational focal lines where the light of distant stars would be concentrated by gravitational lensing.
in so much space debris probability of not hitting any such will be close to zero, its like to await less than 100 hundred car accidents on Earth during 20 years
this may sound strange but i had a dream last night that humans made it to alpha centauri. but this.... this isn't it. Think of it this way what if it were possible to take a similar principal like electric cars and solar panels and make a ship that could go from here to there in 24 hours. Obviously advanced technology beyond our current comprehension. But what if we charged up an engine with our sun. Using solar energy to charge a giant engine that could put us at the speed of light. Think about what could be accomplished if something like this happened. I may not be a scientist but i know it is possible if a light sail can be invented why not go a few steps further than that.
+ken tonseth The idea of a 'star scoop' is a pretty cool one, not going to lie, and a researcher at NASA's Eagleworks laboratory is currently working on the warp drive, but I think the idea of a black hole drive is much more interesting. Essentially, you take some crazy powerful lasers, focus them into a single point, and create a black hole from the energy itself [it'd basically just act like an equivalent mass]. depending on the mass of the black hole, the hawking radiation will differ in strength and the black hole in longevity. If the technology pans out, we could travel at near-light speed to stars across the galaxy, and thanks to relativistic effects, not feel the passage of time nearly as quickly onboard.
The gravity o n a black hole is near infinite. How could you put that thing on a space ship without imploding it.
ken tonseth I knew i was right about farming through RUclips comments for ways that could work...
you are high as fuck
Good luck surviving space dust at those speeds
Once you start sending them, you have to keep sending, so that a long line of nanocraft can make a communication array back to earth :)
I know another way to reach interstellar travel: farm RUclips comments for a way that could actually work.
My question is, how do you slow down when you reach Alpha Centauri?
+Matt Kay They don't, they can't, it's impossible...except for crashing into stars, planets, moons, asteroids or comets.
+Matt Kay Why would you want to slow down?
+Matt Kay 1st step is always flyby, after that orbiter, after that rover
Gilbert Bernas How are you so sure about what a device not yet created is capable of?
Gilbert Bernas I think you are focusing only on capturing an image at the point of fly-by, where the impact of relative velocity is maximized. The probe will take many images throughout the 20 year journey and some will be better quality than others. For the issue of image quality, the probe designers are well aware of the image capturing challenges they face and will have the next 20 years to fine tune the device for precisely this purpose.
At such a speed, even a single spec of interstellar dust across the millions of kilometers traveled each hour would completely disintegrate the chip instantly.
+AvyScottandFlower oh they can just make it regenerative, just add in a few Brog nanobots
+AvyScottandFlower hence why thousands will be sent. Also interstellar space is essentially empty so if they can be precise enough in the launch, then these have a reasonable chance of getting to Alpha Centuri
Veritas Vincit That's an assumption, you can't be sure that there won't be obstacles along the way since no one has made the journey yet, and, as you said, space is 'essentially' empty: presumably almost completely empty, but not completely.
AvyScottandFlower hence why they intend to send thousands, rather than all eggs in one interstellar basket.
+Veritas Vincit Eh, I don't know, sounds to me like the first nanothing that gets obliterated with a spec of stardust would create a huge amount of space debris for all the other ones coming in behind, creating a cascade effect. ISS just had an important (though not fatal, fortunately) impact of a freckle of paint last week on a window of the viewing dome on the ship. And that was just a freckle of paint. At orbital speed. Imagine any impact of anything at a relativistic speed. Pfff
what's solution for revolution and rotation?
How to avoid the planets, stars, black holes will shield light?
I doubt there is any black hole so close to us as alpha centaury - we would have discovered it. Actually Alpha centaury is the closest thing to us that is not in our solar system. Planets are also too far away from each other so there is no problem there. The only problem seem to be interstellar dust and maybe asteroids? Idk.
can they not stop the bots when they arrive via planets slowing them down... cause once we get there we don't want just a flyby
Space is full of so much to offered that no matter how hard it is I'm sure scientists will do the best they can. Like jfk said we don't do it because it's easy but we do it because it is hard. Which is correct even by 60 yrs later people continue to advances.
If space is expanding exponentially, and Alpha Centauri is 4.3 light years away, wouldn't it be a lot further away in 20 years? How do we know the angle it is expanding away from us. I don't know if that makes sense. But say 100 people start walking away from a spot in different directions. You will be a lot further away from the person 20 spots away from you compared to the person the was standing right next to you at the start...
Tom Whiteway actually alpha Centauri is getting closer :P in 30ky will reach the closest point.
RIP Stephen Hawking!
If these collided with some planet in α Centauri at that speed, any alien society would think that we were declaring war on them...
Can you help me where is it now? Has it reached Pluto? What is the distance from the Earth to Breakthrough Starshot now?
It's a concept, it hasn't sailed yet :-)
doesn't exist yet
awesome! maybe they could send bigger structures in selfassembling micro packages...
Maybe that is how we will explore the universe through information.
incoming 100 GW laser beam will heat impact the microcraft even if the reflection factor of it is near 1.0. It will flash in couple milliseconds.
These scientists just want to live not working hard on some real projects
What happened? Are they moving forward...
I had a dream the other night regarding this issue by developing a sail in the design of a contact lens shaped connected to a human eye on earth capable of seeing what is out there on real time. My two cents dream.
how will they make the starchip not burn from the acceleration and close contact to the laser is a mystery for me...
what kind fo material known to human race can withstand such pressure and temperature throughout that long (20 yrs to Proxima)?
How does the starchips will be able to take a good photo of the planet when they will be travelling so fast?
help, does anyone know the answers?
I can answer a couple of your questions.
how will they make the starchip not burn from the acceleration: In space there is no friction from particles like there is in the earth's atmosphere. Hence in the vacuum of space things dont "burn" due to acceleration.
Close contact to the laser: Lasers can be calibrated to different wavelengths and frequencies. For example, those laser pointers popular in the early 200s don't burn through people's hands because of their wavelengths and frequencies. Scientists can calibrate the laser just right so that the material can whitstand it.
what material known to human race can withstand such pressure and temperature throughout that long (20 yrs to Proxima): The effect of the laser on the sail only lasts for a few minutes, after the chip has gained velocity you dont need to keep applying the laser onto it. In the vacuum of space there is no friction because it is a void, therefore there is nothing to slow down the chip, therefore there is no need for the laser to act on the chip for the entire 20 years, it only needs to accelearet it for a few minutes.
How does the starchips will be able to take a good photo of the planet when they will be travelling so fast? I dont know
First i thought, couldn't it be dangerous to send a such a strong Beam onto a mirror that more or less is pointed on earth if it flies away from it. But than i thought, that if this technic is finished, it propably is just a matter of time before they send up a satellite with a big mirror, that is ment to send those laserbeams to what ever place on earth they want. This would be like the weapon from James Bond - Die Another Day
How could anything that small ever create a signal strong enough to be detected across interstellar distances?
it wouldn't. But by sending a constant string of these things, 1 per day, we'd be able to create a string of crafts and it just has to send a message to the one behind it, and pass it along. It is still an extremely flawed plan. it might take 20 years for the first one to get there, but since the cameras can't aim we are literally firing in the dark hoping to get something. This project could go on and on for decades before it finally gets lucky enough to snap a shot of something. Might as well just take the time to send a real probe.
that beam would become a weapon and fuck up out atmosphere
lolno
Fantastic! :)
I feel kind of bad I didn't even notice Stephen Hawking until I watched it again.
Fuck that eugenisist
How will the pictures/data reach earth again?
the usual
We should already have such objects in our solar system from extraterrestrials; we should look for them
Go, flight!
will the laser push och evaporate the spaceship ???
+SandLeopard003 if anything its more likely to tear the sail than the chip due to its size and the requirement to transfer enough light radiation into kinetic energy to accellerate the craft to 20% the speed of light. Space however is 2.7 Kelvin = -270.45 Celsius = -454.81 Fahrenheit, so its a pretty useful place to do this - in fact the best, nowhere is colder
The lightsail needs to be extremely reflective, lest it absorb the laser and gets vaporised.
Won't the laser beam reflected back to Earth be destructive?
Extremely reflective surface (the lightsail) and a super array of lasers...
This is going to attract interest from the military.
+K Hawk the lightsail will likely scatter the laser.
So in time we could have big enough lasers to send a craft big enough to carry man 20percent speed of light I wonder what the monkeys name will be for the test pilot
Anybody know how long it would take for the information to get transmitted back to earth?
+amanuelamanuel More than 4 years
Well, I guess I can live with that :D
+amanuelamanuel Exactly. The data will be transmitted by radio waves and this travels at the speed of light so 4.37 years
How does it slow down once it gets there?
It does not, it flies by like New Horizons at Pluto ruclips.net/p/PLpGTA7wMEDFjE80Y0wn7Nu_wK1_brG46i
I hope it works, is not that simple to reach that destination at that speed, any cosmic trash would destroy it.
It will work better if lasers are fired from the moon as it has no atmosphere to absorb them
Well how you gonna get a shitload of high-tech lasers on the moon?
Benjamin Schröder Robots my friend, robots sent to the moon to make that work done
wow
Far less powerful lasers have been used to knock drones and missiles out of the sky. How is this minuscule spacecraft not instantly destroyed when it's hit with a 100 billion-watt laser beam?
this is a solar sail not a chunk of metal
Можнавапрос?! А как эти нанокораблики будут тормозить, достигнув АЦ?
+Rudolf Sikorsky Никак.
Их будут сотни, тысячи![sic], и они будут отсылать информацию постоянно. Просто будет окно полезной информации, после чего о них можно просто забыть.
Если я правильно понял, передача инфы будет осуществляться световыми импульсами. Интересно, импульс какой мощности способна сформировать эта фитюлька? И на каком расстоянии его можно распознать?
Rudolf Sikorsky Об этом не говорят. Тоже интересно.
Вот ещё вопросец.
Если аппарат состоит из платки, которую дядя извлекал из пиджака, и паруса, то маневрировать он не может. Может только разгоняться в направлении от источника фотонов, наводиться на цель не может.
Если так, то каково будет рассеяние объектов на дистанции цели? И какова вероятность того что хотя бы несколько КА будет захвачено притяжением Альфа Центавра и приблизится к ней на "планетарное" расстояние? А также сможет запуститься и передавать сигналы (не на Землю ессно, а местным вещать).
Rudolf Sikorsky Маневрировать он скорее всего будет - закреплять парус будут скорее всего на подобие MEMS-устройства.
Все остальные вопросы решаются путём шанса. Если они запустят 5000 таких устройств, 5 доберутся, 2 будут работать в конце.
So Satellites in earth orbit will be zapped together with aircraft and little tweety birds! Could be usefull for zapping earthbound asteroids though. Now there,s a thought.
+Bill Rodgers Not really, not enough power to zapp an asteroid out of its orbit towards Earth.
+SciNews So just planes satellites Space stations and little innocent Tweety birds then.
+SciNews Would it have enough power to change its orbit given several flybys though?
+Sushiman118 "several flybys"? By many different nanocrafts maybe, but still not enough.
SciNews my apologies, I was referring to the concept of an asteroid defense system.
So if this thing would Start today, it Takes almost 25 years to get Some pictures if it really works!:/
Is there someone who can explain to me how this is possible? How can the lasers push it until it reaches Alpha Centauri? What about the Earth's rotation on its own axis and the rotation around the Sun? The light would change its trajectory just after a few seconds. Or will these chips also be flying while rotating around the earth and staying in touch with the lasers? With 1/4th speed of light, i.e.75000km a second, any space debris, like nano-sized dust particles will become significant. Even a 1 nanogram sized dust particle (roughly the size of a human red blood cell) will hit the flimsy sail with a power of over a 1000 bullets, at that speed. A few hits and the sail is in tatters. So how?
The lasers is just pushing the craft to 20% the speed of light and then stops. And they are sending thousands of them and maybe just 100 will Get there
Did you see the keynote? Milner clearly says, they will need several minutes to reach that speed. And even in their video example you see a laser beam shooting the object outside the Earth atmosphere. Since the planet is orbiting around the Sun and rotating around its own axis, the laser beam can't be that straight for even a minute. In fact just because of the Earth is on the move, it will most possibly just have one tiny moment of contact. Say whatever you want, but if you can't explain it better for me it's a fake.
+CalvinMiguel It's not fake, it's a concept. If it will work, remains to be seen.
it's not even being a concept that triggers me the most, what is triggering me is that that are numerous reasons why this can't work and still the one called the mos intelligent one doesn't even bother. As long as nobody can explain me why this can work even though it is bound to fail I can only say scam
CalvinMiguel A scam? They didn't ask you for money. If Yuri Milner wants to throw his money into space, literally, it’s his business. There might be better ways to spend 100 million dollars, but it’s his decision.
Dr Evil, is that you?
OF COURSE Stephen Hawking would be a great Bond villain, this technically becomes Earth into Deathstar.
and it will sent the data back to earth using beam :O really ? what if 1000 planets block this beam how the data will go back
+AKAS liasa There aren't 1000 planets between here and there.
If there were so many planets between us and Alpha Centauri why would we go so far in the first place?
A object worth grams which can reach the moon in 7 seconds is literally going to destroy it. Plus The solar system is covered with objects. You gonna have to get millions of these
👏👏👏👏👏
Can somebody explain to me how it will capture images and sent it back
+King Malik Captures images with a digital camera much like a smartphone, then images are sent back as a radio signal. The transmission will take four years to complete.
+LaborHours but how? because it's traveling so fast
What is the problem with travelling fast?
LaborHours because how will get a clear picture? It's traveling fast
はるこあずみ This is not a problem in photography, it can be done any number of ways. The Voyager was travelling very fast as it flew by planets, but it took good enough pictures, and that was with technology prior to 1977.
why dont we buid up a giant solar panel in the space for powering a big laser so we can travel with it :D
3:50 "Over a few minutes, this nano craft accelerates to about 20% of the light speed". Let's be generous and give him 20 minutes - this would equate to an average acceleration rate of about 50km per second per second (or just over 5000 g). Imagine a rifle bullet travelling at 1 km/s and being brought to a complete halt in 20milliseconds. Does anyone seriously believe that a nano craft can be constructed to withstand that enormous stress for seconds, let alone minutes?
Tomas O Maonaigh this thing isn't supposed to stop...
Considering the size of that microcraft, I have few questions:
how will it be able a signal strong enough to get received from earth?
what is the nature of the data that It will gather?
How accurate will it be?
A. Ahmou I see being as powerful as a cell phone
***** So if it is truly the case, the reception should be a very delicate operation as it should need sensitive receptors.
A. Ahmou I'm more Interested in how it will take photos going that fast. It can't slow down unfortunately
The future is now
+FlameJackstar nice oxymoron
NANOMACHINES, SON
What about the hazardous thousands of probes gone rogue? Do they self destruct before potentially making damage?
Additionally all nations should have a word to say in this kind of matters.
Sometimes, blinded by power and dare we think and act like children -- minimizing responsibility and due. This is not to say *we* humans shouldn't proceed with the operation.
I personally like the idea to the point of a dream come true, it's just I'd like it started once all the possible ethical and security-wise implications both inside and outside of our planet are pondered. So it's an interdisciplinary matter.
This could be a matter of extraterrestrial repercussions over Earth of inconceivable magnitude.
+mireazma care to elaborate?
I can find my thoughts exactly, in your post, Paul. Word by word. Whew! I'm happy to see other people who think this way. We have other priorities like... humanity. We're not civilized enough to match the technology we have on our hands. We're hazardous. And generally concerned about self gratification. Even those who can think further and want to do something for the best still do what they do for science - cold reason - instead of the warm respect for life, humanity, civilization. And the worse thing: it's a trend and it's going to get worse.
I saw that message in teh comment section :
If one of the spacecraft weighed 35 grams, travelling at 1/5 the speed of light, it would have more kinetic energy than the atomic bomb detonated over Hiroshima (15 kilotons of TNT). They're talking about sending 100k+ of these probes to flyby the Alpha Centari system, that's a holocaust for an alien society.
mireazma I'm still sure they will burn of broke if hit something. We have a lot of particles traveling to us fast and always. And don't worry it will end as the anti contamination standards to avoid contact with possible life planets with our probes.
why alpha centauri exactly? anyone?
atually they found one in proxima centaury

20 years after lunch xD
JazevoAudiosurf And another 4 years for data to reach Earth.
Why use lasers just use large reflectors in orbit... silly Breakthrought foundation
Will the real slim shady please stand up
At least this is one of the only billionaires besides Elon Musk is helping advance mankind
nenhum br?...
Kohab star
*CAN PEOPLE STOP TAKING PICTURES SO THAT I CAN HEAR THE SPEAKER?* GOD DAMN! I CAN'T HEAR SHIT!
They're throwing money in the trash. Better to spend money on Earth.
There are near objects near earth that could be hit
Rrrrrrrrr
More lies...
Fuck 0ff
This guy can’t even speak English
why don't we have force fields yet damn what's the hold up its been about 25 years and still nothing wow.
Wow
Why didn't we used it yet?
Where Sheldon Cooper?) :D
I'll do a song of this
