  • Thank you MathieuBC Noel in Second Life for building the space shuttle in the video.

  • Thank you to wrote this comment Archivist. I apreciate

  • expanding "space" , how could something that is nothing or something that is infinite expand ?

  • Well, The space expansion is cause by the energy of the big bang explosion. This explosion was not brief at all. We just can say that explosion persist many years to avoid the force of primal gravity or the space elasticity. Other theory is involve for the space expansion.

  • please show me a movie where space is expanding , for something to do so it needs to have limits but how could space have limits ?

  • space is limit less, You can see only 14 billions light years around the solar system. 1 light year is 9460800000000 kilometers if speed of light is 300 000.You can do the math. Until now, we can't prove the space have an limit because we can't see It directly and indirectly. But directly and indirectly the astronomers can see the acceleration of galaxy and star far away. But caution this acceleration we can see It's made well before the human bean and earth was form by evolution.

  • i can do the math but what importance have the math if directly i can't see in a movie that space is expanding ? In science it doesn't , perhaps for science fiction it does. Let's take it simple : they observe that a corp A and a corp B are now at a distance d and then a distance t. What does this mean? It certenly doesn't mean that if you have two pencil (in right and left hand) and you make them to go into a direction and other that sp. is expanding so other must be the explanation.

  • The space expention is build on the big bang theory. If object gain speed It's accelerate. Otherwise It's grow without an acceleration and still grow. But If you calculate the speed of all object is 0, you can say the space is not growing at all. Finally, you can't see the space grow like the movie, because the grow is invisible now. You can fell the wind but you can't see It if you don't add dust in the air. We can't travel as far the moon now whit your technology. So maybe in an another lives.

  • You don't udnerstand what i am saying. I understood that i can't see the limits of space but what i am saying is that to imagine a space that have limits isn't at all possible. If space have limit then there must be some objects that encapsulate space but by that we would imply also that that object is infinite and doesn't ocupe space. So a space with limit is a stupid definition. Finally we define infinite as the lack of shape and because it lacks shape it can't grow.

  • @carusggg it grows from a smaller infinite into a bigger infinite, consider perhaps the following, i have an infinitely dense soccer ball and an infinitely big tennis ball, the number of the points in both objects are both infinite but the soccer ball is quite clearly bigger than the tennis ball, but if the tennis ball beleives in itself and with an iiiiiiinsy tiiiiinsy bit of magic it can grow and all its dreams will come true :D

  • @KamikazeChicken5000 and lol sorry im a month late
