Do you guys think that there's a end to space? like a big wall I mean. and if there is what do you think is on the next side? Or do you think space just keeps going and going
Scientists say that we can only see as far as the universe is old. The universe is estimated to be 14 billion years old. If that's true we can only see 14 billion light years away, so there is a horizon 14 billion light years away that we can't see beyond. Some even conjecture that ours might not be the only universe, there may have been other universes created the same way ours was. And since we can't see beyond the horizen, no one knows what's on the "other" side.
"Andreas Albrecht, a cosmologist at the University of California at Davis, says the question {are there other universes} isn't open for debate. Why? You can't argue with quantum mechanics. "As far as we can tell," Albrecht says, "that's the fundamental language that Nature speaks. Nature doesn't answer questions for certain; it answers questions by giving probabilities."
And in quantum mechanics, "There's a possibility that almost anything happens." Including other universes. And if cosmologists are queasy about that, they don't have a choice. "It comes out of the mathematics," Albrecht explains. "It's forced down our throats."
"Quantum mechanics will not give up these other alternatives on its own," says Albrecht. "And we really don't know what to make about that. On one hand it sounds totally metaphysical. On the other hand, it's all we have to work with at the moment."
So I don't know, but I'll leave it for bigger minds.
I think it just goes aroung in a circle
