Is our universe part of a greater multiverse?

Question

and if so, are we in one of the unlikelier ones?

Answer 1

Very well could be. We would be in one of the unlikelier ones because most would be unsuitable for life.

Answer 2

Yes, I believe that we are part of a greater multiverse. It's what makes sense. Whether we are in one of the unlikelier ones depends on the numbers, which are huge, so there are probably many universes that support some type of life.
I think we tend to think to small, and perhaps in the wrong terms. We live in a universe that has 11 dimensions, even though we only really 'acknowledge' 4. But E8 exists in 248 dimensions. It seems to me that we may be missing some important information.

Answer 3

i think that is very likely that we are part of a multiverse. it would be very arrogant of me to just dismiss this possibility.

i feel that we can't be the only intelligent (and i use that term loosely) life in our universe, and if this is possible why not other universes?

unlikelier? we are probably in a young universe going through a rebellious phase.

Answer 4

That is one of the questions that I don't think I'll learn the answer to in my lifetime.

Are all these multiverses in turn all crammed in a pod-like meta-multiverse?

Or are they clustered like grapes in a bunch?

Do they share some, any, or none of the laws of physics?

Does time exist in these multiverses?

Perhaps our own universe holds micro-verses inside blackholes or singularities?

Is this a universe or are we forever caught in an event horizon?

Is time, and not distance, the ultimate hurdle for traveling between (or among) universes?

Is entropy a regressional phenomenon elsewhere (or elsewhen)?

And finally,

Are we but a stage in a Matrushka-like set of overlapping series of particles, like we're halfway from muons or quarks through a larger, universe-sized particle?

Answer 5

I think our infinite Universe is part of a greater whole, or a multiverse. It makes sense according to some theories I've read.

Answer 6

Think about this. If God has been around for all time. And Jesus is the Creator. Don't you think it would be rather prideful of us to think that we are the only creation out there? Well I think so. So seeing that our solar system is VERY small in comparison to our Milky Way Galaxy (in fact if you take our solar system and imagine it the size of a coffee cup and place it in the Milky Way, in proportion the galaxy would be larger than North America to put things in perspective) and even smaller in the grand scheme of things, what would keep Him from creating massive amounts of solar systems and galaxies and all kinds of things.

If you look up at the handle of the big dipper and hold a penny at arms length and block out that portion of the dipper, you block out over a 1000 galaxies that dwarf the Milky Way in comparison.

Multiverse? nah I believe there is one Universe but its so vast we cant even begin to comprehend it. But I plan to spend some of my eternal life soaring to these unknown worlds.

Answer 7

Maybe.

I'm inclined to think that if there is a multiverse, then there would have to be an infinite number of universes. So we'd be among the infinitely unlucky but also infinitely lucky.

Mmmm... pure speculation. :) If only I knew enough about math to know what I'm talking about.

Answer 8

Alan Guth's calculations of the inflationary universe seem to account for a lot of astrophysical data, and extrapolating that to the negative energy created, it would seem that the expansion of one universe would give birth to trillions of other universes.

Why not after all. It is egocentric to think only in terms of "ours is the only one." It was once thought Earth was the only world--wrong; our Sun was the only one--wrong; our Solar System was the only one--wrong; our galaxy was the only one--wrong.

So probably, yes, there are other universes, probably a near infinite number.

Answer 9

I was reading an article not long ago that suggested our universe was generated via the collision of two other universes. It was one of those theoretical physics concepts that really made my brain hurt.

Every so often I have to read something along these lines to really humble myself. There are some seriously smart people out there.

Answer 10

I think that if Black holes are gravitational vaccums and they are reducing matter into a single point, it only makes sense that there is something beyond that point of matter. That could very well be other universes. In which case they may have differing physics to ours and life may be a unique to our universe. Maybe not.
