My confusion stemmed from the assumption that the universe for much of its lifetime must have been expanding at beyond the speed of life in order to have reached that dimension. As indicated by the SixStringSamurai, that's not a necessary assumption.

Wow, that's some crazy stuff. Thanks for the reference. I'm sure I'll have to read it again. (I actually thought the universe could be 27.4 billion light years wide--that is, a radius of 13.7 billion light years.)

cool... and now i go back to watching other videos and going back to my normal life not even bothering about astronemy... but id like to know how we know how long the galaxy is how we can predict what the milky way looks like and whats at the "end" of our galaxy it still doesnt make sense. and if anyone think that any other life form as complex or even more complex than us exists is just obserd and would make us to rare to be found...

a light year isn't a measure of time. its a measure of distance - how far light can travel in one year. so if you go the speed of light for 78 billion years, then you've gone across the universe.

Yet humanity is still involved in such matters as economics!!!! meaningless power and religion... It is about time to start thinking differently.

I thought the same thing too for a long time until I read this article. The universe is 13.7 billion years old, but this doesn't mean the universe is only 13 billion light years wide. Search Wikipedia for "Metric Expansion of Space" and read the section next to the blue cone like thing on the right. |
