Do you believe in a parallel universe?

The fourth dimension is time. (Quote)

That is unconfirmed, and really the idea is not very comforting for most scientists. I do not believe in a 'parallel universe' at all; due to the abundance of space expanding, I fail to believe that there is another paradoxical universe replicating the value of our Omega.

No I am not. The universally quantified axioms of physical science are not empirically verifiable so any argument based on them cannot be sound. We simply do not know if these assumptions are true.

I'm really not sure about parallel universes. It's not something you could back up as being totally feasible like the existence of life elsewhere. The ideas are intrigueing, but we just can't know yet. Maybe we'll never know.

Take a read of this ShenLong. Ignore the title as it is misleading.

It shows that there is a possibility that there might be multiple universes. The researchers, as the article states, acknowledged that could have been just the occurrence of unlikely statistics. They are now looking into it further. If there is multiple Universes the data may give us an idea of where to look.

In the inky blackness of infinity and eternity, 13.7 billion years ago, our universe sprouted like a mushroom. I expect eternity and infinity has many such mushies.

I read that quantum physics speculates eleven dimensions (four of which we operate in). In infinity and eternity, where our universe is so small, I expect there could be other dimensions.

I absolutely love the multiverse theory and the relevant word there is theory.

It is eminently possible but - with the nature of the standard model of physics - I fear that it will remain theoretical.

Multiverse is one of three areas of physics that make me feel like I've had my brain hollowed out and replaced with sand, the others being string theory and imaginary time.

If we are lucky and affects of seperate universes can be felt way in the forms of gravity or whatever, from vast vast distances, if we come up with much better instrumentation we may have a chance of sensing it. This is all of course assuming that that "big bangs" happened extremely far apart from each other.

Then again me may not ever be connected to it in any measurable way.

That's the biggest load of bullshit I've ever read. Thermodynamics, electrostatics and the basic force equations can be demonstrated by a four-year-old.

They are supported thus far by empirical evidence. Have experiments been done 10 billion light years from here? The assumption of uniformity in physical law is just that, an assumption.

When a law is stated as a universally quantified proposition it has an infinite set of instances. The laws cannot be affirmed empirically unless it is affirmed for ALL of its instances. Humans have been around for a quarter of a million years and we will be gone in less than ten million years. We do not have enough time or smarts to test every last instance of our general physical laws. And that includes the laws of thermodynamics. No one has ever shown a LOGICAL contradiction follows from a violation of thermodynamic laws. All we have is partial empirical evidence for these laws. And that pertains to all scientific laws we have formulated. Supported -thus far by experiment-. No guarantee that somewhere, sometime a contradicting fact will not be found. That is why science is provisional.

My own take on the whole "parallel universe" idea is that it's an elegant solution to many of the paradoxes in Quantum Physics, but it cannot be empirically tested so it's a non-scientific theory. Still, it is worthwhile thinking about it.

Well I think it's plausible. Other universes could exist possibly. Many scientists actually believe that our universe was born from a dying other universe. Thus our universe might not be the first and certainly not the last.

What intrigates me is could it be possible to travel, or at least communicate with one of these other universes?

You can't get there from here.

I do believe it but I can't prove it in any way. Just think of anti-matter to matter or negatives to regular picture film. That is how I view a parallel universe, that one universe is an energy reproduction of another universe

Now is this universe the picture or the negatives? That I don't know.

Fouth dimension is time. An alternate universe would include its own separate fourth dimension/timeline. IE, the 5th dimension (so to speak) would be where it would include alternate dimensions.

I don't particularly believe it or not, by the way. It's just fun to try and stretch your brain in different ways...so imagining "higher dimensions" in that sense is fun for me.
