I saw a documentary where they said it's believed that the universe is basically like a balloon constantly expanding. I'd that's the case, what is it expanding into? It's all interesting stuff...
@Laughman I don't think so , that film portrayed space being bent as in a wormhole. The space bending in rocket propelling is not actually bending space the same way as a wormhole. It creates a void in space where the rocket moves into because of the void. In this way it creates a void in reality and so not causing any effects of velocity on the pilot. Bob Lazar explains it better, but he is accused on being a fraud and charlatan.
@Laughman An energy is generated using the Element 115 (it has only been made artificially in small amounts)and where ever the energy is pointed causes space to 'bend' . It's highly theoretical but the USA is accused as having a large quantity of it and may have experimented with this propulsion system already. The future is almost scarily unpredictable
As long as there was a beginning to the universe, there will be an edge. If the universe is 14.5 billion years old, the universe cannot exceed 14.5 billion light-years in distance.
@Alison So the speed at which the universe is expanding is increasing, perhaps exponentially? I think this is where dark energy comes into the discussion, right?
Not as far I'm aware. Everything is expanding so fast we only gonna see so far tho. Also in our visible universe it seems a big chunk of it is being pulled by gravity from something we can't see and never will: point is something is beyond what we can see.
In this context, "lacking a boundary" does not mean an infinite extension into the past. I believe Einstein was specifically talking about a "hard stop" at the "Big Bang" with the disclaimer that stop is where our human understanding begins (or ends). It doesn't mean activity wasn't still taking place. In fact, the Bible suggests it was. It's tough to get the human mind around.
@SW-User Speaking of the simulation hypothesis, that sounds a lot like filling in the gaps with god, doesn't it?
SW-User
@U53RN4M3 it is actually. It could be us running a simulation from the distant future . Is it one entity running a program,multiple entities as a competition? Out of pleasure, could it be machines trying to recreate the beginnings like we are trying to right now? That’s why I like this theory. So many possibilities
This is a visual depiction of bubbles in which each universe has its own domain of physical laws. It is stuff of fantasy with nothing to back it up. Right now they question that the universe is even expanding. It was a hoax.
It's speculated that space is flat, not flat as in 2D, but 3D kinda flat. The same way that the shell of a black hole is theorized to be a flat projection of everything that's in it. That's because when you theoretically shine two laser beams parallell to each other out into infinity, eventually they'll collide. How can two straight parallell lines cross each other? well draw two straight parallell lines on a globe/sphere and you'll see for yourself. But take it with a grain of salt, all of this, since we're stupid human beings that not so long ago thought earth was flat. Including your statement.
