      You say in 2:48 that Alpha Centauri may have a planet-like object with a mass from 9 to 35 earth 2:57 masses & a radius of masses and its radius may measure 3.3 to 7 times that of our planet. If it has between 9-10 earth masses, it would be a rocky or terrestrial planet. However, if it has more mass it would be a mini-Neptune or a gas giant. So, I take the possibilities of life developing in such a place are 1 in 4 or 0.26%. Not such a good candidate.

    Only a few of Earths radio broadcasts are at 100,000Kw and due to the D^2 law, that signal is lost in the galactic background radio noise at about 2.2 light years. So no, our broadcasts haven't reached even Alpha Centauri. Some RADAR and very high power directional signals yes, but due to angular movements, those have to be aimed precisly at, and track, a receiver to convey any meaningful information. Otherwise, it's just a "wow" moment.

      This seems to beg the question then, why are we bothering with SETI? All those massive satellite dishes beaming messages into space, I assume with stronger signals that will make it farther, but ultimately it's like covering 0.00001% of the galaxy instead of a mere 0.000001% from our usual signals.

      @@Durzo1259 Actually all those dishes are just receivers, they’re just listening. Hopping that someone out there is either broadcasting at insane amounts of power, or directing a powerful beam signal directly to us. (Or at the Star, assuming that someone listening will be in the cone of the signal.) We did send one message, once, from the Arecibo dish. I suppose the “Dark Forrest” theory has kept us from doing it again.

      If there is in fact a large planet in the habitable zone of Alpha Centauri A, it may have a habitable moon. At this point we don't know anything definitive, other than Alpha Centauri A is unlikely to have any sort of large planetary system. Alpha Centauri B seems even less likely. As for Proxima Centauri, there are planets there, but anything habitable seems unlikely, but not impossible.

    I wonder if you could use the clockwork radio principle to power a probe that won’t be needed to be activated for decades, or possibly even longer.
    Like a probe sent to Alpha Centauri perhaps, with Solar Radiometers on the probe to both activate the probe as it nears the Solar system its aimed towards, and recharge the clockwork mechanism like a giant self rewinding watch that never stops running.
    The electronics would have to be powered like a clockwork radio, negating the need for batteries or Nuclear power, which will degrade over extremely long periods. This is the issue with the voyager probes as they age, despite the fact that the electronics and computers within the probe are functioning perfectly after nearly half a century of constant use.
    The probe would have to be large and capable of making independent decisions, which may require a large amount of older hardier computer chips.
    You could even go a step further, and have small landers on the larger probe that could be fired and directed towards other planets. They could be hardy probes, with a self contained non rechargeable clockwork power source of their own. Preferably a hardy probe to gather planetary data quickly, similar to the Venetian and Titan probes of the past.
    The only issue would be having a secondary rechargeable clockwork mechanism to power the transmitter, which would have to be very powerful for the extremely long distances to earth. Storage of information until broadcast would be vital.
    If Spacex can reduce the cost of launches further, perhaps we could have a mother ship probe that could launch smaller satellites like a Clockwork Cassinis, to examine planetary systems and their moons, as well as launch the aforementioned smaller probes.
    This is a bit long winded and hypothetical, but its worth thinking about.

    Proxima Centauri B planet sounds very similar to Io moon around Jupiter, similar difference in size ratio, similar orbit - and Io is NOT a pleasant place to be: high radiation from Proxima Centauri star which is a flare star, multiplied by the strong magnetic field like Jupiter has causing X-rays; and also lots of volcanism due to the geological effects of the tight orbit and slow rotation. That slow rotation would also minimize B's own magnetic field, as it does Io; leading to more radiation getting through and less ability to keep any air.
    On the other hand, Io has a ring around Jupiter because of all the gases in its orbit, I wonder if Proxima Centauri B planet would have less of that due to its greater gravity, or a bigger one?

      I tend to think that while life in the universe is probably plentiful, INTELLIGENCE (alien technological civilizations) is exceedingly rare.
      Just look at our own world's evolutionary history: out of the billions of species that have arisen on earth over the last 3.5 billion years, only ONE of those has produced a civilization-building species. Just ONE. Out of BILLIONS! And our species' journey on that path took a great number of events to happen 'just right' for our abilities to outpace simple animals. Its the very definition of an "extremely low probability event."
      Intelligence on our level to create technology & build civilization is clearly not a requisite for survival. So, I tend to think that the frequency of this occuring on a universal scale is extremely low.
      So while the probability of life in our universe is probably high, the probability of other intelligent space-faring civilizations coming to earth to meet us is probably science fiction. And nothing more than that.
      (Also... Even IF there are civilizations out there, the probability of any "alien civilization" occuring at the same time as our own is infinitesimal. WE really just started being a "civilization" for only a tiny fraction of the 300,000 years of our species' total existence. Humans didn't even invent "civilization" or even farming until 5000-8000 years ago... and we were around for 290,000 years before that. *And thats 4000 years of human civilization out of the 3.5 BILLION years of the total history of life on this planet!!!* So the probability of any other civilization maturing in the same time period as us, even to within several thousand years of each other, is extremely low.).

      And my comment above doesn't even take into account the astronomically huge (maybe even physically impossible!) Issues associated with
      1. The near impossible tasks of making ourselves visible to others within our galaxy, and/or of detecting others' presence within our galaxy.
      Our entire history of emitting radio into space has only resulted in a bubble 200ly in diameter. In comparison to the galaxy, this is a tiny zone. Its like a salt grain on the edge of a dinner plate... And any civilization on that 'dinner plate' thats not winthin that 'grain of salt' BY DEFINITION can't detect us!
      (And even within that tiny 200ly RF bubble, almost ALL that RF energy has reduced in power to be basically indistinguishable from simple regular background noise. Due to the inverse square law of RF power to distance. Our non-directed Radio signals, which is almost all of our broadcasts, will be unresolvable past just a few LYs.).
      2. The perhaps physically impossible task of interstellar travel (certainly beyond our small corner of our own galaxy).
      3. The issues associated with numbers 1 & 2 above are multiplied exponentially when considering them outside our own galaxy! Simply put... We're not detecting anything (let alone travelling) outside our small tiny corner of the universe as a whole. At very best, we're stuck in our own galaxy forever.... and most likely, within a small portion of it. The larger universe is not accessible to us, nor is our galaxy accessible to "others" in other galaxies.

    "...one hundred and fifty percent smaller than..."?
    * How in the hell does THAT work?*
    I'm not a mathematician. But I DO know that one hundred fifty percent is by definition LARGER than the base object being measured.
    I point this out because of how often I hear people who most certainly SHOULD know better than to use this errant method to describe things.
    An object cannot be "twice as small" as another object when comparing the two. In order for this type of comparison to be used, there must be another object by which to compare the first two objects. For example, "Star A is half the size of star B, but star C is even smaller...twice as small as star B as compared with star A".
    I know this can seen as nitpicking, but given the current levels of education in the world (how much the AVERAGE PERSON can use accepted scientific and mathematical knowledge, as well as logic and reason, to identify, test, observe and interpret their environment), we are in trouble. Fueling this recession of intelligence, ironically, is the age of information in which we live. Any person can inject and spread incorrect information to the world. And people do this on a regular basis. Flat earth, anyone?
    So when those who are in a position to affect the world by spreading real, scientific knowledge fail to do so correctly; when these people fail to enforce and maintain THEIR OWN PRINCIPLES of logic (by incorrectly phrasing mathematical relationships, for example), then societies, or more specifically, the people of those societies lose their ability as a whole to think, to learn, to understand, to interpret, and to communicate scientific principles and ideas accurately and effectively.
    This type of bass-ackward logic, that one thing can be twice as small as another without a third point of reference is just wrong. I can only ask that, moving forward, your videos and other communications would be more careful when it comes to these small, SEEMINGLY insignificant errors. Yes, it can seem like nitpicking...I get it. But when those who are responsible for "maintaining the standard" fail to do so, then what outcome is possible other than a loss of precision, the necessary loss of knowledge which follows that loss of precision, and the general reversing of understanding?
    I've heard it said (and I wholeheartedly agree) that those who have become the Great People of History didn't do so by doing any one thing supremely well; rather, these people became great because they did all of the small, SEEMINGLY insignificant things very well.
    In other words, it is only by the careful guarding of the finer details that the overall picture can gain clarity.
    Maybe thinking of the situation as a digital image, which relies on the fidelity of its individual pixels for its overall sharpness, would help to see the importance of this issue. After all, the last thing we need is to revert to a Neo-Dark Age of ignorance, especially when it is wholly preventable with the disciplined application of principles which we already know.

    I think that thinking about planets to move to is crazy right now. More logical to focus on getting a permanent orbital station going, then a station on the moon, then one or two mars’ moons, then figure out asteroid mining. While that’s going on we have to also figure out better systems on earth too.
    Once we’ve done that, and we can mine & manufacture in space, we can start thinking about sending something autonomous to set up an outpost near the Centauri system. This outpost can send back more data about the system, taking measurements more directly than we can from here; which can let us know if it’s even worth sending people out there. Repeat process until we do have a system worth sending people to.
    Then, hope we’ve advanced socially enough that we could send people on a multigenerational space voyage without them killing each other during the trip.
    Do it right and there should already be infrastructure for the colonists to use when they arrive.
    Do it wrong and you have a decent sci-fi Netflix show.

    I'm pretty sure Jim Henson had the Alpha Centauri system in mind when he wrote "The Dark Crystal"
    I'm always fascinated by this stellar system, in fiction and in reality. Could the probes actually get there in only 20 years? I wonder if I might live to see the first images from another star's planets? That would be so amazing.

      If we could get spacecraft up to only a fraction of the speed of light, which is definitely possible, then yes since its only 4 light years away it wouldn't take relatively to long

      Most likely just a bunch of barren rocks and gas giants if we’re being honest. Probably a lot of asteroidal bodies too given the bizarre gravitational forces.
      Earth’s atmosphere and life most likely evolved as a unique combination of factors including a calm solar system (after the great bombardment), a single moon, and a very average star.
      A system with two or three very different stars is likely to be subjected to bizarre gravitational affects, radiation patterns, and lots of tiny worlds ripped apart before anything interesting develops.

      @@kirishima638 We only have one solar system that we know for sure has life to make comparisons with, so I'd be careful before making any assumptions. After all, every other time we've thought the Earth is special, we've been proven wrong. Humans used to think the Earth was the centre of the universe (wrong), then just the solar system (also wrong), then that humans were the only examples of intelligence (also wrong, just ask dolphins and whales, elephants, corvids and octopodes). We thought the other bodies in our own solar system were mostly barren rocks. If you know anything about the gas giant moons, you know that's hardly the case. We thought Sol was the only star with planets. Now, we're finding planets even science fiction didn't dare dream of!
      The universe is an amazing place, and there's far more we don't know about it than not.

    At 1:08 you say "our radio signals may be heard on a number of potentially habitable exoplants". Only, they won't. The inverse square law comes into play -- the further you get away from the source, the weaker the signal. And any terrestrial radio signal will grow exponentially weaker. Our radio signals become indistinguishable from background noise at around a light year out. And no advance technology can fix that. It's like trying to detect the ripple of a coin thrown into the pacific ocean from the Santa Monica pier, while standing on a beach in Japan. No amount of technology can correct for that. You start running into hard physical limits.

      I always find it interesting, how many boring people have the desire to comment on these videos. It's like you lack any imagination."No advanced technology can fix that" Except it will. It will be a different kind of technology with a different kind of approach. It's like going back 4000 years and telling Babylonians to count Pi to let's say 100 000 000 decimals. For them an impossible task and today I can do it in a few min with my PC. And now imagine you would tell them we can do it for 31 trillion. To make it short he is right and you are wrong since you have no idea what kind of technology will these receiving planets fathom.
