Earth Gamer: Man my Ping is 140ms
Mars Gamer: Man my ping is 22 minutes
😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂 must be nice playing league on that internet
Don't mind the speed, we can work around it by reviving a BBS kind of service, but that lag is insane.
Jesus is returning soon🔥 Repent and turn away from your sins to obtain salvation 🤗
Even worse when you consider than "ping" is defined as round trip delay, whereas the 22 minute figure is one-way.
I imagine in the future we'll have to have datacenters mirroring data to other datacenters on other planets and seevers will be by planet lmao
This honestly feels like a SciShow video, in a good way. Well explained and easily digestible.
Sounds similar also

Imagine aliens intercept our laser communications and see cat videos. Really shows humanity's obsession for our fur balls.
You mean videos of the life forms they use to spy on us?
Cats are the best :)
Für
No, what if the aliens think that the cats are video calling and that they are the most intelligent creatures on Earth
And imagine this: They then look at it and say: "damn, we thought the humans were apes. But they are like us - cat people. Let's visit" and that's how we got our alien catgirl girlfriends ;)
Starlink is also one of those examples of inter-satellite communication where they use laser to transmit data between satellites.
yup, its pretty insane
Should be entirely possible to turn the entire thing into a giant infrarometer. A telescope the size of the solar system would be cool.
Am watching this via SpaceX Starlink! For anyone in a remote setting, it's life-changing technology! (And a large cool quotient too!) 😎✌️
Except their laser communication (most important part of starlink) does not work.
@@hubertnnn Last I checked more than 8000 starlink have laser links. It's standard equipment going forward.
They needed them for polar coverage sometime in 23.
I was able to download the entire Kessel run in 8 parsecs.
Nice
A parsec is a unit of distance, not time
@@TheEGames True, but it doesn't matter as long as you shoot first.
@@TheEGames Don't tell Hans Solo.
@@TheEGames Whooooooossssh
We got cat videos on Mars before GTA6
thats false. there is no down in space.
Alright I got a solution, Inload and Outload, Argument invalidated ┐(‘～`;)┌
We are still solving for dark matter. In or out might be inaccurate. Maybe before and after?
The enemy's gate is down
In space we call it left and right load 😎
Or up
Torrenting from Mars is still going to suuuuuck. 😛
better that torrenting from my dog
Why would it be different?
It would take longer just for the first click. When you get constant stream of data, it's the same. It is like buffered video on RUclips.
Gonna need a sneaker net.
the latency on mars is still going to be brutal 45 minute ping time simply because of the speed of light
I love how at this point you just rounded an entire minute of ping 😂
Mars has a smaller diameter and thinner atmosphere than Earth so ping times there should also be lower
@@shanent5793 ... You understand what Speed of Light is and why we can't send data faster than that, right? And that it doesn't depend on the atmosphere or diameter of a planet...
@@acmenipponair He probably ment a communication between two points on Mars
Someday hopefully if we have a human colony on mars, we could set up and internet cache system, data centre on earth sends (whatever data) to mars to be stored and accessed locally, depending on the population and interests, AI predictive models could pre spool up data. We cant change the speed of light, but we could be sending data packets in the mulit terabit or even petabyte range in the next few decades. having a data transmission that big could almost negate the latency time.
05:59 they did really send a cat video! 😸
I feel like there's enough precedent at this point that you're basically obligated for your first transmission to include some kind of cat meme
Should have mentioned the data rates of comms with the Voyager probes!!
Currently it is 1200 bits/s
Jpl says it's 160 bps!!
With 150,103,840 ms roundtrip ping.
@@sandmaster4444 160 bytes per second is the same as 1280 bits per second so you are both correct here.
@@jnhkx that's actually accurate lol
I can't even tell you how happy it makes me to see space and nasa represented outside of their specific channels.
Imagine getting a high def photo of Uranus...
i hope the alien's are not light-based
else they might see the cat attacking the lazer as an threat
I mean it's a beam of light traveling through a very small spacs, it's probably really really hard to intercept that even if you know its coming
If the aliens would be light-based, they would think the laser beam they got the message from are we. :D
Cats would be the ones to start an intergalactic war
The alien's what? Did you leave out a word?
@@EhrenLoudermilk maybe cats are just using us to become the rulers of the galaxy 👀
Here before the bots to watch a video on a question I never asked myself.
Hmm, this bot seems self aware... We've gone too far with AI. Time for the Butlerian Jihad
I did. I played too much KSP.
And my uncle was part of the team
This is funny
so that means you have nothing better to do
It's been said, I'll say it again. This is sci-show levels of communication and subject matter. Well done. Lets have more of this please.
I loved this video; so interesting. Riley, we need more of these!
For terabytes of data, the good ole pigeon carrier method would do well in the future. Using missles instead of pigeons.
"Weekly RUclips subscription USB missile incoming. Brace for impact. In 5.. 4.. 3.." 😂
I love this guy, whether its LTT or here, each time makes a video about things ive always wanted to know. + doesnt have an annoying voice
One advantage you have in transmitting electromagnetic waves in a vacuum is that the speed of light c is a constant for all frequencies. That is not true in a material because the phase velocity in a dielectric material will differ with frequency. To send information you need a band of frequencies around the carrier and so in a material (i.e. circuit board) the different phase velocities of the different frequency components will cause dispersion and signal integrity issues.
Love that y'all are doing space videos!
Space isn’t really empty around our planet when you think about all the satellites that are flying around us at any given time!!
How I imagine the Mars colony internet would work would be that the most popular content on Earth would be curated by an AI every day, then sent to Mars to be stored locally for the entertainment of the people living there. That way, you could still scroll on your phone during your break or downtime without having to wait for the system to ping Earth for it. If you do want anything else, you can still request it, but you'll have to put up with the delay. The system would also work the other way round.
Bro spent so much time yapping about DSOC, he didn't even answer the original question. What is the download speed on the ISS?
He kind of did 5:15
You expect this kind of relative question in a such condensed subject as fucking LASER telecomunications for satelites light years away with asteroids and stuffs is rather dumb, you can make it out depending on distance which is probably what he said either between 1mbp/s to roughly gigabit speed if its closer like a satelite orbiting moon
@@AlamoOriginal What moon? The Moon (Luna), Phobos, Demos, Io, Titan? Lots of moons out there.
@@uss-dh7909 the Lunar moon of us obviously
LTT channels are just click bait like this
TLDR: The ISS has like 300 megabits, but it still is like a billion ping.
The ECC on that signal would be a fascinating topic
can't wait for the first Civilization game played between a Martian and an Earthling
this reminds me of a silly story on "the daily WTF", about tourists on a space station.
one of them complained about his internet lagging and DEMANDED that the tech FIX it.
she said something like, "i can't change the speed of light", and the VIP had NO idea what she meant!
the story is called "radio-wtf: space for guests".
(RUclips almost always blocks direct links to other sites)
I genuinely love these videos. I watch them in a curated playlist. LOL
This shows how slow light actually is , in grand scheme of universe, light is too slow to be meaningful
Interesting stuff!
Thank you!
Techquickie has quickly become my favorite LMG Channel.
Riley is the perfect host for this
happy to see the concept of "tight beam" communication from The Expanse become reallity
Me to myself when i clicked the video: "You know, I have been asking myself what are the download speeds in space?"
Lol
Man, wouldn’t it be crazy if there were patents for quantum entanglement communication devices that you could view on Google patents
Absolutely whiffed the opportunity to say "We're comin' for Uranus"
dos melhores techquickies dos ultimos tempos!
hope you guys more nana tech in the future!!!
3:00, i thought that was my Fold going. Heart skipped a beat.
Good job my friend.
Please bring more Mazda, Lotus, Noble, and Gordon Murray to the game!
2:57 Hurry back, Riley!
Quantum Entanglement ❤
the future of space internet is going to be a massive data server that sits in space that then communicates long distance over starlink-esque systems to other servers so you can do massive data dumps as it makes its way to the next server imo, since having a direct call every time for a specific piece of data is dumb you need to have mass storage instead basically cloning everything on earths internet and then dumping it again on server on mars and vis-versa allowing for what will look like near instant communication when in fact you will still be between 3-30 minutes of delay in actual data.
additionally you will need to develop some sort of mini nuclear reactor to deal with the power issue.
aside from this you will also need to develop some sort of live communications network between earth and mars that fixes the delay not sure what this will look like probably something with quantum computing and physics cause it probably isnt possible other wise.
This explains why we do not receive radio transmissions of other civilizations in space. They also made swift transition to lasers and directional aspect of lasers makes it almost impossible to receive by a chance.
Not really. Even at lightspeed the Radius we can listen to or send is sooooooo small. Imagine our galaxy is the earth and now you are on a beach and the area we cover is smaller then a grain of sand. There would be no way that someone is that close. So someone would needed to send a signal thousand years or even longer ago so we hear or see a signal today. And ttthats only our Galaxy. Now imagine billions of billions of other earths in space. Even if there would be someone he needed to be in our Galaxy and that really close (in space meaussures)
@@Blackbirdone11 I know all of that 4D puzzle of space and time. But moving to lasers it makes receiving signal exponentially less probable. So going back to Fermi’s question, everyone is where and when they are supposed to be, but we will just never receive anything.
I’ve been wondering this for so long
IR can go through clouds, if I'm not mistaken. Also dust. That makes it a very compelling candidate for the task. It makes me hopeful that scientists will find more and more ways to make this faster.
My big concerns are any potential for atmospheric or gravitational lensing, but I know these issues could easily be conquered.
Remember when laptops used iR data transfer before WiFi?
And oops. My hand was in front of the remote control when changing channels on tv..
great info....
More like this!
Haircut looks nice, suits you
Yeyy... we're doing space
dang....i never thought of that...
im curious how much cosmic radiation and comsic rays actually effect band width...
fantastic idea for a video...👍
Space lasers. I knew it. Is a tinfoil hat enough?
Beams the laser in the wrong direction and accidentally calls some poor alien’s mother a “wonderful lady”
When the guy playing on mars has better ping then you
Can you share the link to the full video of that cat clip you have used?
I love you editor
The video loaded like hell. The first 10 seconds it was all choppy and sounded like robot sex. I had to rewind it 😂😂😂😂😂
Cool !
The frequency does not limit the amount of data that can be sent over RF. The modulation and channel width are the factors there.
A 20Mhz wide channel with 1024 QAM is the same regardless of frequency. The frequency changes the propagation characteristics of the wave, low frequency passes through matter better than high frequency up to a point, eventually the higher frequency can pass between atoms, but that's a whole different thing...
A 20MHz wide channel will alias itself at frequencies below 10MHz making the signal unusable, so there is some dependence on frequency. Lower frequencies passing through matter also limits the signal to noise ratio, effectively reducing the throughput.
And wouldn't the signal dissipate over distance..?
@@garystinten9339 yes, the beam divergence is limited by diffraction, so for a given aperture size a higher frequency will have lower divergence, which will also improve SNR
so, basically those furball are our actual overlord?
I already see the roast: "Even Mars has a better internet connection than you home"
i hope fictional concepts such as "sub-space communication" can one day be a reality....
Hii we love u from Ethiopia
the ending shouuld have been :"We are coming for Uranus"
I think the Space Station internet should be pretty decent with all the satellites we’ve been pumping into orbit
WHO LET THE EDITING GUY COOK??
Should have said we're coming for Uranus 😂
Good to know interplanetary communications have a higher bandwidth than Windstream VDSL
Can we transmit doom on these soon? I mostly just want to hear the that doom was running on a satellite
It’s impressive to think we can communicate with Mars in my opinion. I get terrible cell reception and Radio stations all the time so space Agencies must be incredibly patient.
Imagine working for NASA as a cat photographer.
..even gigabits per second.
Alright.. movie night is good for the moon.
Or how about projecting it to the moon and stream netflix on it eh? 😂
Using this network, the ping would be approximately 0.00333564604 milliseconds per kilometer. So ping to earth, when you would be on Mars (if the distance would be 225,000,000 kilometers), would amount to 750,000 milliseconds (750 seconds, so 12.5 minutes).
To the Moon!
Feel sorry for any alien watching us through a telescope and being blinded by a laser. Those barcode readers in the supermarket are bad enough.
Talking about DSN while sponsored by Odoo... Captain Sisko wants a word
I am curious what level of power these lasers need for that kind of range.
You can increase transfer speeds by also using a meshed network. If you had a base on Mars, you could split the packet into 3 (for instance), send it to a satellite each then to the base where it gets reconstructed.
Ain't no way a breakthrough happened on my 27th birthday that's wild
Like a gameboy color infrared link on steroids or an infrared TV remote
Today I learned that beaming internet to mars might actually be faster than the fastest broadband in my neighborhood.
OMG!!! Space lasers!!!
mars network: DSOC
my network: this suck
Light breaks up with space, and not to mention atmosphere of planets
Riley needs to be signed up to present science docs... I swear, this guy could make tax returns amusing!
One step closer to Space Olympics.
imagine the aliens are cat people and they saw the cat videos.
Better question: What's the ping? 👀
Should be between 6 and 44 minutes on Mars. Imagine commanding a rover with that shitty ping.
Astronomical 😂
Approximately 0.00333564604 milliseconds per kilometer. So ping when you would be on Mars (if the distance would be 225,000,000 kilometers), would amount to 750,000 milliseconds (750 seconds, so 12.5 minutes).
Where's the quick bits? I'm starving!!!
Australian radio telescopes are not within bowl-shaped mountainous regions... rather tehy are just in the middle of a large area where there are restrictions on what radio communication is allowed.
basically: the government just designates an area several hundred kilometres wide and says "nope" to people using certain tech.
It’s just like an invisible, legal bowl shaped mountain.
22 MINUTES??!? IS THAT A FUCKING OUTER WILDS REFERENCE!!!??!?
We need satellites in the Orbit of Mars who communicates with laser and can also send multiple waves to Mars.
Since radio wave is technically a form a light, is wifi then technically a form of optical networking? 🤔
it could technically be but it's only half dublex
@@gamecubeplayer”dubplex” …
0:56 Australia and Spain are big places, WHERE are these dishes located, the USA got a specific state.

How to test the speed of quantum comms..
Send a quantum command to a craft near Mars and get the response back by Radio . If the response comes back in half the expected time, then the quantum speed would be faster than light.
I wonder how much scrap value that Cali antenna will fetch? 😅
I'll be 63 in a couple months and spent today under my travel trailer fixing water damage, which I will continue to do until it is all fixed. Laying in gravel is more fun than our stunning 2.02 Mbps download speed today.
Does the movie Gravity buffer when the astronauts on the ISS stream it??
