Does Space Go On Forever

This mass is on all the sides.
Does space go on forever. So why do scientists think that space goes on forever. That means if you and a friend each had your own rocket ship and you both took off and travelled in a straight line forever and forever you would never meet. Bill nye answers the question does the universe go on forever as part of his weekly series tuesdays with bill. It s because of the shape of space.
The current view in cosmology is that space was already vast and possibly infinite in extent at the big bang event. What s more likely is they would see a part of space that we will never ever be able to see. The universe is big enough that we can t see all of it for a number of reasons. We really don t know if space goes on forever.
Let s assume that the space doesn t go on forever and it ends at some point where there is a solid mass or a wall that ends it. Our part of space or the observable universe has a special shape. This week a team of scientists announced tantalising hints that the universe is actually relatively small with a hall of mirrors illusion tricking us into thinking that space stretches on. And there are ways that we could live in a space that doesn t go on forever but still has no actual edge to it.
Our part of space or the observable universe has a special shape. Our part of space or the observable universe has a special shape. It s easier to imagine if we think about a universe with only two dimensions. Nasa says it needs a new space toilet for the artemis moon missions.
That s a lot of time but the universe is big enough that scientists are pretty sure that there s space outside our observable bubble and that the universe just isn t old enough yet for that light to have reached us. So why do scientists think that space goes on forever. That means if you and a friend each had your own rocket ship and you both took off and travelled in a straight line forever and forever you would never meet. It s because of the shape of space.
It s because of the shape of space. That means that light has had only 13 8 billion years to travel. It has been expanding ever since but not into something else. Space probably does go on forever but the truth is we don t know.
In theory space goes on and on so why do scientists think that space goes on forever.
