I thought of this when comming down from a salvia trip. beyond our universe, there is nothing. no matter, no energy, no time, no laws of physics. no laws of physics... no laws of conservation of matter or energy, no law of enthropy, no laws of quantum mechanics. beyond our universe matter and energy CAN concievably be created and destroyed. what would be the nature of this matter and energy? absolutely random and constant. matter and energy would be in a constant state of partial existance simultaneously being created and destroyed. since there is no law of enthropy, order can occur randomly, that may be how our universe was created. there are no laws of quantum mechanics. subatomic particles may exist that are larger than planets, and there may be particles that are physically impossible in our universe. there may even be more forms than just matter and energy. no nuclear forces, atoms may exist that have an infinate number of protons. Since anything beyond our universe is impossible to observe, it's all speculation. Does this speculation seem logical?
While I'm no physicist, if there is something beyond our universe (if we are actually in a UNI-verse) it could seem to be something like this. Many theories, such as M-theory, suggest a "multiverse" or a group of many universes, in which our laws of physics could be completely different from another universe's. This is something that we really can't even fathom. Just totally different laws of physics = no space/no time, no matter, possibly antimatter and dark energy. It's quite a mindbender
What's the "m" stand for? Is is "modal". The philosophical position "modal realism" is one which holds that there are an infinite number of concrete, causally isolated, non-spatiotemporal possible worlds of which ours is only one. It's ALOT more complex really, but the "M" made me think of modal logic, which made me think of modal realism, which made me think about possible world semantics and um......yeah.
I was thinking, what if there were other big bangs within our universe? The light of it just hasn't reached us yet. But anyway, the universe is EVERYTHING. Even other multiverses...
Matter can be destroyed when anti-matter and normal matter interact. The space between galaxies is increasing. It's not like the universe is some blob of goo that is slowly expanding out it's container.
I don't believe this is true... According to Wikipedia our observable universe is 92 billion light years across... How can that be possible when our universe is only 14 billion years old and nothing travels at the speed of light but light itself? Our universe is 'spilling out of its container'.
I'm not sure how this could be either. Maybe light has had time to begin it's initial journey before the object which it was emitted from/reflected off of began moving further away from us, this way we can still see a projection of the object's early existence before it became unreachable by light. I don't even know if that fully makes sense, It is hard to explain without being able to draw it out or explain in purpose. Also, I am most certainly not a scientist.
No it does make sense. Light didn't really have a head start, what is happening is that space is expanding faster than the speed of light. It may seem like it had a head start, but that is only because our universe has been expanding since its creation. The light had time to travel because the distance was much shorter much longer ago. The things that we see which are 5 billion light years away (Which means we are seeing as it was 5 billion years ago) could be 10 billion light years away now that the light has traveled here... It really depends on the rate of expansion versus the speed of light to how far away it really is, five and ten billion light years are arbitrary terms.
That's basically what I was trying to say in my post.... but you seem to have it figured out a lot better than I do.
althought one might be tempted to point out that: i. there are no outer or inner limits to the universe (i.e. infinity), ii. hence the phrase "beyond our universe" is impossible, iii. therefore observation becomes moot.
the first one isn't true if you consider time a dimension. since we think we know that the universe is 14.7 billion years old, than the outer limit of our universe would be before the big bang. By "beyond our universe" I'm implying either some outer limit beyond infinity, or before the big bang.
Good point, although even if time is taken as a dimension, there would exist vacuums before and beyond the 14.7 billion years.
correct, absolute vacuums, devoid of physical laws, the exact same kind of "place" where I envisioned this thought experiment
Spade and someone else posted a video on this a while ago. The 'universe' came from nothing Everything is moving away from each other And the 'universe' is expanding faster than the speed of light Greatest time to live in the expansion of the 'universe' is right now! The light hasn't dimmed completely out of sight...yet. This topic just completely fuckn' blows my mind and is honestly beyond me.
