RE: Simple Question #3 - How big is the Universe? What is its Shape?
Very interesting to learn that the universe may be expanding faster than the speed of light. I often think about the fact that if we were to be able to travel faster than the speed of light, and then create an extremely powerful telescope and point it at earth, we would be able to observe events that happened in the past. Like what happened to the dinosaurs or who assassinated JFK!
Love this post. Liked and followed! And I am doing a similar type of series on chemistry if you'd like to check it out!
To view the past of the earth with dinosaurs, we must at least go 150 millon light years away from the earth at the present instant. Which is probably not possible at present.
But maybe if the research of worm-hole gets successful, then we'll be able to do that in future.
And yes, I am already familiar with your chemistry posts. You're really doing an amazingly innovative work.
