I guess we need some ship that can reach warp factor nine then.
Exactly, as far as we can get is nowhere worth going.
That won’t stop them from pouring our money into the effort, not for a second.
The Fermi Paradox is based on assumptions that may not be present and invalidates the conclusion.
So what is it that makes it impossible?
The nearest star system to ours — Alpha Centauri — is 4.3 light-years away. That sounds like a manageable number until you realize that a spacecraft traveling at a speed of one million miles per hour would take 25 million years to reach it.
Assuming that Feynman is correct and there is no “new physics” on this. There’s lots of “resources” in the solar system to harvest from metals to organic chemicals - methane, etc. So depending on earth needs environmental protocols it could be worth the trip.
A lot of what we take for granted today was deemed “impossible” not very long ago.
We’re all still working with sub-light phenomena. It’s never considered that just maybe we’re missing something major that the rest of these star faring aliens have figure out and we just can’t see yet because we haven’t developed the tech yet...
Thought experiment... You are utterly blind. There is an entire civilization around you that communicates entirely by pictures. You listen, you feel, you smell... but nothing you can observe that way gives you the necessary info...
Now imagine you communicate and travel by means entirely beyond our current understanding because we are limited to the EM spectrum. Would we even recognize an alien “signal” we can detect with out limited senses as something alien?
In a billions-year old universe, there may be, or have been/will be, beings smarter than Richard Feynman.
“From the absolute limit of the Speed of Light “
There was also the same “calculations” for the speed of sound with claims that the speed of sound could not be broken.
Einstein never said his work would not be altered, just that his mathematical observations at the time formed his conclusions. There, so far, has been no other conclusions for the absolute speed of light other than the energy necessary to propel the particle.
Science... Sometimes it makes sense and this makes complete sense... We are alone, have been alone and always will be alone... Period!
Newtonian physics and slower than light energy requirements.
Most people have no idea how vast the known universe is.
We’re just tiny little specks ‘bout the size of Mickey Rooney.
“Assuming that Feynman is correct and there is no “new physics” on this.”
I wouldn’t assume it. There is loads of research going on that suggests we have not yet begun to understand particle physics, time, energy, or matter.
There’s a lot of “there” out there and more stuff there than we have here.
There were trees, metals, and food in Europe and we still came to the Americas.
In case you didn’t know, there are those FReepers who believe we never ever even made it to the Moon.
Filmed at Hollywood back lots ya know. Never mind the tens of thousands of people with first hand knowledge. They are all liars too.
A.I. Feynman doesn’t count. Interstellar travel is absolutely possible, it will just take a long time and require a lot of energy. Decades at least to reach just the nearest stars. Fusion power using an asteroid-sized fuel tank of deuterium could do that, albeit very difficult but not impossible.
Even with a pessimistic view of the Drake equation... Us being alone is mathematically impossible.
