RE: Why Us Being Alone In The Universe Is An Absurd Idea
one problem is the sheer SIZE involved and the relatively slow speed of light.
it takes an hour and a half for the light of the sun to get to earth.
it takes four YEARS for light to get from the nearest star to earth.
and type of spacecraft that we have any idea of building would be much MUCH slower than light.
That's so true! Compared to the size of the universe, the fastest thing that there is (light), is ridiculously slow. So even if we figure out how to travel at light speed, we just can't explore the cosmos in a meaningful manner. Only if somehow we achieve things like warp drive can we truly explore and know for sure about the other possible civilisations out there.
P.S. Light takes 8 minutes 20 seconds from the sun to Earth.
