It is interesting to note that the largest discovered star in the universe is VY Canis Majoris. Its diameter is such that to circumnavigate it ONCE will take us close to 2000 earth years. So i guess if we boarded a standard passenger aircraft around when Christ walked the earth, we would finish one trip about now provided we lived that long. Yeahhh… we could do it faster if the Concorde was still around. Probably in about 800 years. I suppose there would never be a shortage of fuel

And that is one star among the trillions. Space is HUGE and we earthlings are like an atom.

so we cant ever reach the end of the universe? sounds like the universe is a black hole then too and as far as expanding goes, couldn’t it also be that the universe is dividing down the space inside, thus making it look to us that it’s expanding… anyway too much red bull today, very nice article! cheers.

Geez, Phil, you gave me the chills! It’s so…mind-boggling to sit back and consider how tiny we are in the grand scheme of things, and then to remember that there are things even smaller than us! It makes my head get all woozy just thinking about how much there is out there to discover, and how little we’ve really explored. Oy.

@ Allen (141) -
Er, no.

While, over large enough scales, space expands at or faster than the speed of light, nothing locally is moving that fast. I.e. the expansion isn’t objects moving through space, it is the space between objects that is expanding.

The author said ” If you could somehow hitch a ride on a photon, the fastest thing in the cosmos, you’d still never reach the edge of the Universe even if it had one. That’s because the edge would be receding away from you faster than you could reach it. You’d forever be playing catch-up. Literally, forever.”

If I were to fasten myself to an object touching the edge of the universe, would I be moving faster than the speed of light? How about stars or galaxies or “stuff” near the edge: do the move faster than the speed of light as well? Are there any relativistic effects on mass at the edge?
