I can't even begin to grasp concepts like the multiverse.
I believe we exist in a multiverse of universes.
There are many of us thinking of one version of parallel universe theory or another. If it's all a lot of nonsense, then it's a lot of wasted effort going into this far-out idea. But if this idea is correct, it is a fantastic upheaval in our understanding.
Maybe it's due to my west coast liberal upbringing, but, the idea of parallel universes doesn't strike me as being too far out there.
I've always been fascinated by physics and cosmology. It gets more and more scary the older you get.
There was a time when 'universe' meant 'all there is.' Everything. The whole shebang. The notion of more than one universe, more than one everything, would seemingly be a contradiction in terms.
You almost can't avoid having some version of the multiverse in your studies if you push deeply enough in the mathematical descriptions of the physical universe.
We have to wonder, if there is a multiverse, in some other patch of that multiverse are there creatures?
I find the whole time travel question very unsettling if you take it to its logical extension. I think it might eventually be possible, but then what happens?
Scientists say, 'There is no such thing as time; gravity is a dust from another universe, and outside our own universe are many, many universes in all directions.' They speculate that attached to these universes are probably 6,000 planets identical to Earth. So are there things living out there? Animals, people, anything?
The word 'universe' is obviously not intended to have a plural, but science has evolved in such a way that we need a plural noun for something similar to what we ordinarily call our universe.
Now, what space ultimately is - I should confess, I think most physicists believe - we don't yet know.
I have a vast curiosity about our universe, our origins, and its probable future.
Even in empty space, time and space still exist.
Although we don't know what is outside our universe, astronomers still wonder. Several pictures of what there might be have been dreamed up. An interesting one, called multiverse, has lots of universes. Picture it as a foam of bubbles. Our universe would be one bubble, and we'd be surrounded by lots of other bubbles.
The Universe in a Nutshell
The bottom line is that time travel is allowed by the laws of physics.
And what we know, or think we know, about the universe of space and time is changing very quickly.
Sometime in the future, science will be able to create realities that we can't even begin to imagine. As we evolve, we'll be able to construct other information systems that correspond to other realities, universes based on logic completely different from ours and not based on space and time.
I wouldn't say that 'The Fabric of the Cosmos' is a book on cosmology. Cosmology certainly plays a big part, but the major theme is our ever-evolving understanding of space and time, and what it all means for our sense of reality.
We are actually living in a million parallel realities every single minute.
The mind of man has perplexed itself with many hard questions. Is space infinite, and in what sense? Is the material world infinite in extent, and are all places within that extent equally full of matter? Do atoms exist or is matter infinitely divisible?
String theory envisions a multiverse in which our universe is one slice of bread in a big cosmic loaf. The other slices would be displaced from ours in some extra dimension of space.
What you can show using physics, forces this universe to continue to exist. As long as you're using general relativity and quantum mechanics you are forced to conclude that God exists.
I've always really been into science, and in the last five years I've gotten into theoretical physics and the origins of the universe.
Technologies that may be realized in centuries or millennium include: warp drive, traveling faster than the speed of light, parallel universes; are there other parallel dimensions and parallel realities? Time travel that we mentioned and going to the stars.
