Then he needs to give more money to NASA, Musk, Bezos or whomever.
Proxima Centauri in 25 years
- Thread starter XCV330
- Start date
Mars has been a destinaton on programs of record for awhile now, but the actual destination as of this moment (who knows, could change?) for the Artemis Program will be a south pole landing location on the moon in addition to the orbiting Lunar Gateway station. Shackleton Crater is being considered. There are zones of nonstop sunlight there good for solar power, and conversely, in shadowed cratered regions of nonstop nightfall, there should be water ice that could be mined.
New FTL paper.

Hey isn't Alpha and Proxima Centauri around 4.5 light years from Earth?
Would any of our radio / TV have reached there by now?

Long ago.. No one there to hear them, I suspect.
"They" would have to have 1960's-1970's Radio Telescope Technology for the last 80 years. Since we are not detecting radio waves from them, then I say no one is home, or too primitive. If more advanced, good chance they first detected our early transmissions, and turned off their stuff (this could too profound for any civilization to give up all their communication systems) so we won't discover them once we develop radio telescopes (that's what I would do so as to continue to listen in for years until we are confident that contact will be beneficial.)
Oh no I know that. No one alive there to pick them up. But what's to stop other civilizations in that short range from existing? For all we know they got them but won't or can't be bothered signalling back.

Here’s a list of all stars within 100 lys.
Most of them have been reached by our oldest radio signals already.

Cool list.
I was watching some docos over the weekend and it really got me thinking that maybe IF there are other worlds with life out there that maybe they don't want to reply to anyone's signals, not just us, maybe most worlds have gone that way because they realise that if they do respond or show that they got a signal that there are other species that might not be so friendly.
Just seems to make a bit of sense though that if you have numbers of civilizations around the universe they might be aware of each other but not really communicate because the moment you pop up and are noticed there might be species that think your world would be somehow worth noticing for things like resources or commodities, or that they are just not very nice people.
I'm beginning to be of the opinion that we're all alone in this stellar neighborhood, at least in terms of starfaring civilizations. Intelligent life may be rare enough and rarely gets that extra nudge to begin some equivalent of the agrarian revolution and the (relatively) quick journey to technology that develops after that. Human beings existed for well over 100,000 years on earth moving around and settling everywhere they could, but once someone came up with the idea of staying put and planting seeds, it was a pretty short time to where we are now. If, for instance, some catastrophe had only left north and south america settled, it would have taken longer due to a lack of beasts of burden and certain geographic challenges, but it was going to happen. But if the entire world had been some place not helpful for transitioning to that economy and lifestyle, it would never have happened. If most living worlds are water worlds, all the moreso due to a lack of combustion and metallurgy.
To be even more bleak: some civilization in the galaxy, even in the universe, had to be first to get out beyond the gravity well on its own power. Someone had to be "the founders". I know its astronomically hard to fathom, but what if its us?
That's entirely possible. But we have a long, long way to go before we become a starfaring civilization. We can't even get along as nations on one planet, space forget that. We have a hell of a long way to go before that happens.
It's definitely a bleak idea but I like it.
We became starfaring awhile ago: https://en.wikipedia.org/wiki/List_of_artificial_objects_leaving_the_Solar_System
But not in a meaningful sense, yes. Still, if there was a will to do it, we could have been building nuclear pulse Orions to travel to the stars 30 years ago. One of the saddest things not spoken much about in the history of spaceflight has been the luddite reaction to nuclear power in space and how hard that has held humanity back.
If NASA had not had to have given up on, say NERVA, we could have had Apollo capsules visiting Jupiter and Saturn.. some TIME ago. Who knows where we'd be now. Humanity has instead been trained to believe that their smart phones and game consoles are really neat, and they are, but we absolutely have retarded our forward progress. This is not where we could be right now.
As a product of the 1960's space race
, our current space advancement is disappointing 
, and I see my future hopes dashed. 
My 30+ years of experience as both an engineer and a manager in the nuclear field has given me this sad reality. I only have about 25 years left in me (if I'm lucky) to behold something wondrous. "Maybe" man back on the Moon or possibly on Mars in my lifetime, but only a thin "maybe". At this point, I would welcome a space-based, extremely large array multi-spectrum telescope to explore the surrounding star systems and other phenomena.
It's been said that it's quite likely that most advanced (i.e. Intelligent) races don't survive long enough to reach maturity. They either die out from disease or war, or a natural catastrophe.
This galaxy alone has over 300 billion stars (that we can guesstimate) and so far, a LOT of the star systems we have tried to check out with our puny technology appear to have some type of planet(s) around them.
If just a tiny fraction of the planets out there have life, and a tiny fraction of those have intelligent life, there could still be hundreds of sapient races out there - just in the Milky Way.
Some of those may be roughly where we are in advancement, some may be behind us, and some may be so far ahead that we would hardly be noticed. Considering that the Milky Way is (over) 100,000 light years across, there's no way to know how long it would take for our -increasingly weak- radio signals to reach someone who is advanced enough to hear them and actually would care to hear them.
I don't consider this to be depressing at all, just reality.

Hey what if humans or something very much human evolved on another planet of its own accord just like us? We wouldn't then be so rare then, and maybe the humanoid form is a practical form.
This would be another example of Hodgkins's law of Parallel Planet Development.

Yes it would. But it wouldn't be that outlandish to consider such an idea would it?
So, have you ever tried plugging numbers into the Drake equation? Last time I did that, I came up with between 1 and 25 civilizations currently existing in our galaxy and capable of radio communication. That implies those civs are separated by tens of thousands of light years on average if none of them has colonised farther than their immediate neighbourhood.
I haven't done it in quite some years...
It's somewhat sobering to do so since it proves (in theory) just how few worlds are likely to be inhabited by anyone, let alone advanced enough to have a 'fighting chance' at establishing themselves out of their home system.
On the griping hand, their are -at least- as many galaxies out there as there are stars in the this galaxy so, who knows?

I'm glad the lowest number was one.
