Right!
So flying into a black hole zaps you into the 2nd dimension for a bit and then the Whitehole brings you back out to the 3rd dimension.

That's what I think.

Oh!  Or maybe into any other parallel universe (I hate to induce any sci-fi feelings to the term; what I mean is another universe with the same 3D coordinates as this one, but seperated by the 4th or higher) where white holes spit it out.

Is it entirely far-fetched that eventually, dark matter (you know, and matter, but dark matter is like 90% of the mass in the universe) catches up with dark energy, causing the collapse of the universe with such force that it inverts, giving itself what would be considered a negative mass.  Then white holes pop up connected universes (well, multiverses now) that have the opposite mass, hence antimatter, while the other matter is what we would consider matter (although to one theorizing before or after the collapsing incedent, they would consider it antimatter).

Re: Theoretical Physics

Hm, I wonder if the universe is actually collapsing, not expanding, but we see redshift because as it gets smaller, everything else gets smaller, too.

Anyway, I believe that white holes are white because all of the light from a black hole is being expelled from it. In fact, I bet people could mistake white holes for stars.


So, in theory, you could create an artificial sun with a white hole.


EDIT: Page 6 get

Same for the theory. So, I also think that the light from the black hole is also from a black hole in a different universe, and that the're connected with a wormhole.

How come you get all of the posts on the next pages?

Not quite, if I understand you correctly.  The light that comes out of black holes is caused by the heat of the density of the objects that got sucked into orbit around it.  The gravity of the black hole is so great that it causes such heat in them that they glow brighter than most other known light sources.  See quasars.

Re: Theoretical Physics

I'm going to take the "fabric of space" analogy too far here:

Gravity causes depressions in the "fabric"; looking on the other side of the "fabric" (parallel universe?) these would be viewed as "lumps"; they wold repulse things on the opposite side of space time.  Conversely, massive objects on the "other" side (the underside/not our side) would create "lumps" on our side, resulting in "dark energy".  Conclusion: dark energy is the gravity of a parallel universe.

@ = something massive (star maybe?)
----- = fabric of space/time

----------_@_----------

From this side, the "valley" caused by the star appears to be a "mountain", repelling all objects away from it.

Of course, this theory only provides for two universes.  Perhaps the gravity in every universe is felt as dark energy in every universe (besides itself).

Matter is sucked into the black hole, goes through the wormhole into a different universe, then comes out the white hole.

Re: Theoretical Physics

I don`t believe that travel through a black hole is possible: Under the infinite gravity in it, time would be infinately slowed, so you would never come out of it.

I suppose a parralel universe offers a kind of solution to this, but there are many, many complications also associated with the travel between universes... I think it`s important to note that this is theoretical physics, and there`s one theory or other you can use to argue almost anything...

Also: If this does happen, not all the matter that goes into the black hole can come out the other side - at least some has to stay there, otherwise I think we would have far fewer black holes because they`d have "evaporated" away because of hawking radiation.

Unless you can see any other way for them to gain mass?

I haven't read through the entire discussion, so maybe someone has already talked about this:

I don't think time travel will ever be possible. Time is the measure events/existence, and is just a man-made measure. In other words, time isn't a thing, it's a somewhat arbitrary measurement. So you can't "go back in time" since it doesn't exists.

Did that make any sense? I have no idea if this is true or not. It's just the result of a lot of thinking.  smile

This is incorrect.  For one thing, there is something called time dilation, which is time travel.  We time travel all the time.  When you move, time passes slower for you.  In other words, you travel into the future.  We just don't notice it because it's such a small amount of motion that we move at (it's a fraction of the speed of light, so pretty much everything we do will be a tiny fraction).  However, it is enough to throw our watches out of sync!

Wow! That is crazy stuff. Thanks for sharing!

Re: Theoretical Physics

Here is a theory I thought up about parallel universes:

The Sub-Parallel Theory

I think that there is an infinte number of parallel universes, and it grows more each day. Let's start with the start of time, when the first event happened (let's say it was discovering fire) there are supposed to be two possiblities on what the cavemen did when they discovered fire. These are countless, and even more so. As we all know, all parallel universes lead off to different, time-changing events. These too have multiple answers. So alas, come sub-parallel universes, which grow from the alternate possiblilties from parallel universes. This repeats, and soon, we infinite parallel and sub-parallel universes.

Actually, there is a equation of this:
² = or number of parallel and sub-parallel universes
n = events in our universe and parallel and sub-parallel universes.


n² = number of universes

Re: Theoretical Physics

@NeilWest:

I don't really buy into your theory, but:

The "number of events" in our universe should probably be broken down to the smallest possible unit of time, with nearly an infinite number of "sub universes".  Events that had a major impact on humanity aren't special in the grand scheme of things.  Since you can break down time to an almost infinitesimal amount (eh, might have misused that word), you'd end up with an infinite number of universes after the first second.  I have nothing wrong with an infinite number of parallel universes, but I don't really see where all of this energy is magically coming from to create them.  hmm

The grandfather paradox can be solved if you consider the "multiple universe" theorem, so that two universes are created, one in which you never exist and one in which you do.  Therefore you simply cross from the universe in which you do exist to the one in which you don't.

Re: Theoretical Physics

Here's a thought. Would you kill everyone with overpopulation if you went back in time? For example, you travel back in time 1 second. Then one second later, the old you travels back one second, and this repeats infinitely. Does this sound plausible?

Well, this is hard to explain, but it's not. Because you would travel back, see yourself traveling back, then travel back again.

Like in Back to the Future.
Marty sees himself going back when he is in the normal time. Then blah blah blah happens, and it only really happens once, but your past self is forever stuck traveling.

Re: Theoretical Physics

Grandfather problem: You would not cease to exist, but nobody but your time traveling companions would know who you are. You would go back in time, so now you exist back in time. Killing your grandfather would cause you to never be born, but since you already exist, you don't just poof out of existence. It would just be like if you never were born, but you are alive already and come from a different past (past? future?) so you are existent. But, you would be going back to a different past/future and so the people there would no nothing of you.

This goes with how time travel works in the book "Pathfinder".

Anyway, there is a way to kill all of humanity, simply travel back in time and kill the first man. Of course, doing so would kill yourself.

No, because it would erase the first version of you everytime you went through.

Why and how would travelling in time erase other things?  And if travelling back in time was erased, then why would you be back in time?  What about that law that by studying objects, one can deduce what happened for every moment in time, even if it's a task above the capacity of human mental capacity?

@TorbyFork234: But then why would your grandfather be dead, and by extension you, meaning that you'd never have killed him.  And if you never killed him, then you would have been born to kill him.  So you would kill him and not be able to be born.  Meaning that you would never kill him.  But then if you didn't kill him, then you would still be alive.  You get the idea.

I don't really understand why people keep challenging these time travel paradoxes, saying that nothing changes.  Must I remind you that there is, in reality, no such thing as free will; everything we do or think is a result of neurology, even if it feels like free will to us.

Yes, it does. It's impossible to create or remove mass from the universe, therefore it does. If you "destroy" something, all the mass it had still exists, just scattered into sometimes atomic or even subatomic particles, making it hold true to destroying particles: They would break up into smaller particles, which would continue infinitely. Also, a necropost is only really a necropost if the topic hasn't had a post for at least 6 months. This only hasn't had a post for 25 days.

Actually, you mixed up some words in your definition. The law states that mass cannot be created or destroyed, not removed. Removing means removing them from the universe, which still doesn't break the law of conservation of mass.


However, annihilation does break the said law. Maybe the law is just referring to matter/antimatter by itself, with no contact by a respective antiparticle. That obviously doesn't break it.


I don't know, maybe I should look into the law some more.

Re: Theoretical Physics

i believe that for every choice you make (i.e what to eat for dinner) a parallel universe is made for each possible choice and and the ability to travel between these would Simulate TIME TRAVEL.. Don't see how lets say that we went to the universe were all of the masterminds who allowed us to have the technology now decided not to because it was CRAZY than we would still be running around with bows doing our hunting..
