parallel universe?

Question

is it possible that there is a parallel universe outside of our solar system? I was just wondering because if there was, that would be really cool, but also, i was wondering, if NASA built the right space shuttles to go at the right speed, faster than the speed of light, then would it be possible for people to reach that parallel universe?

Answer 1

The short-form answers to your rather long and windey multi-question is "Yes", and "No" Yes it is possible, string theory seems to point in that direction, and No, you can't go faster than light. "186,000 miles per second, its not JUST a good idea, its the LAW!!!"

Answer 2

A parallel universe doesn't need to be outside our solar system. There's a theory that a "universe" can occupy the same space at the same time as ours, but the physical laws in that universe would keep us from see it (or touching, or hearing, etc).
And.... NASA is quite a few years away from building a ship that can attain the speed of light. Even if they did - it may not mean a trip to any parallel universe.

Answer 3

Yes, entirely possible. Probable? Who knows yet.

There are "theories" that allow for other regions that are currently unobservable, and which for want of a better word are called "universes".

The classic model is to think of a sheet of paper as a 2 dimensional universe. Any 2 dimensional beings confined to the sheet would only be aware of stuff on their sheet, and would not be aware that a third dimension exists. However, to us, with the benefit of access to the third dimension, there can easily be other sheets ie other 2 dimensional universes.

Now try to extend this idea to our 3 dimensional universe and the possibility of other 3 dimensional universes. Don't worry if it is difficult. That didn't stop luminaries such as Einstein (and Gauss and Riemann?) from contemplating such an extension!

If NASA can make the space shuttle go faster than light before it is decommissioned soon, then the project will likely be extended!

The current census of thought amongst the pros is that faster than light travel is not possible. I'm not going to argue with that! At least not in this universe!

Answer 4

If there is such a thing as a parallel universe in the way you describe, it wouldn't be outside our solar system. It would be right in front of us all the time. We would never see it because we're in tune with our own universe and its respective laws and properties.

Additionally, if you wanted to accelerate a bowling ball to 99.99999999999999999999% the speed of light you would need to store up all the enery created on the entire planet earth for one whole week. Every bit of weather, geothermal, nuclear, electrical, and every other kind of energy produced on the planet, man-made and natural, stored up to 7 days' worth, would propel a 10 pound object at that speed.

So it's unlikely that we'll ever hit light speed. However, there ARE objects bigger than Jupiter moving through the universe at precisely that speed, which gives you an idea of the kind of power and energy out there in the universe.

The people mentioning wormholes are a bit misguided. There is no trap door or gateway or portal in a black hole. You don't go in one end and come out the other. You go in and are squeezed, torn apart, and crushed into an atomic singularity. The only way you could escape is particle by particle over millions of years via Hawking Radiation.

Answer 5

I have little idea which theory you are talking about.

1. In case you're thinking about the multiverse theory: this assumes that there are an infinite number of parallel universes, each one at least a little different from the other. It's not a case of being outside the solar system. Some of these universes have our solar system in them, whereas in others it had never formed.
There are little or no proofs of this, although our speculations of time travel depend on their existence.

2. If you are thinking about the theory that two universes exist 'side-by-side', one of which is ours and where the highest possible velocity is c; and the other universe being one where c is the lowest possible speed of anything -- then here too your question is meaningless. These two univeses are supposed to exist in 'parallel', meaning the other universe is right here, we just can't see it (or feel its presence in any way).

3. If you are talking about another region in space made up of antimatter just as ours is made of matter (like positrons in place of electrons, that sort of thing), then it probably exists. But that isn't a parallel universe, just another region in our universe made up of antimatter. Same for parity theory: some space where every particle is 'twisted' the opposite way compared to here.

Hope this helps. And frankly what you propose (going FTL) is a very improbable prospect, as of now. And if that other world is made up of antimatter... well, let's just say I hope we aren't sending astronauts.

Answer 6

There is no way of telling if parallel universes exist or not. They are outside of our universe entirely.

The space shuttle could never be accelerated faster than lightspeed either. Actually, nothing can. Light speed is like a universal speed limit.

In fact, the space shuttle never gets above 0.0003 % of the speed of light, and it uses up almost all of its fuel to do so. Modern technology is not capable of accelerating a spaceship anywhere close to fast enough or long enough to make such high speeds even worth thinking about in any practical sense.

Answer 7

Its very possible and because our solar system is part of the universe that is included too.
It all started when String theory and dark matter made the physicists think 3 dimensions weren't enough. There are 11! They think that the membranes of the parallel universes ripple through the 11th dimension. They also think that the big bang was the aftermath of 2 colliding universes

Answer 8

A parallel universe can share the same space as ours. You would not have to travel anywhere. However, the whole idea of a parallel universe is that there is no way for beings in one to make the hop to the plane of existance in the other. First, we would have to detect that universe, then we would have to modify our bodies so we could live there. It seems unlikely we could do the second until we at least did the first.

Answer 9

NO.

There is no parallel Universe. We do not even know the full extent of "this" Universe. However, we do know that astronomers, using the most sophisticated optical telescopes , can "see" objects in deep space at distances of 13 Billion Light Years in all directions from Earth. And, were that not enough to joggle your mind, Radio Astronomers using the world's largest Radio Telescopes can "detect" objects in deep space at distances of 40 Billion Light Years in all directions from Earth. That is not the END of SPACE. It is just the limits of where our present level of technology fails us and cannot provide any further useable information. Space, itself, goes on far beyond that and some even say it is infinite. I am not personally able to discuss things like "infinite distances" but I can tell you the 40 Billion Light Years is:

40 Billion times 6 Trillion Miles

and that is a very long distance.

Since Space is even bigger than that, SPACE is huge
beyond belief.

NASA has no capability to build a space ship which will travel at the speeds necessary to come close to the speed of light which is 186,000 MILES PER SECOND. Currently the space craft we know about (not those on the drawing boards) travel at speeds around 25,000 to 50,000 Miles per HOUR.

Notice the diference between "Second" and "Hour" in those specs.

There are 60 seconds in a Minute,
and 60 Minutes in an Hour.

So to make the numbers equivalent you would have to multiply
186,000 Miles Per Second by 3600 to get Miles per Hour...

And you can see that we are talking about a speed some 10,000 times faster than our current technology, which is just not possible today or anytime in the near future.

What is even worse, traveling at some super duper speed like that, how in the world would you ever be able to slow down enough to make a reasonable landing and not crash?

It takes just as much fuel to slow down as it does to accelerate up to speed.

Answer 10

Speed does not really have anything to do with going to any parallel universe.......That has to do with time travel and thats going as fast or close to the speed of light.....A common theory for parallel universes is wormholes and kerr holes and things of that nature.....And no, NASA hasnt even finished building the International Space Station....

Answer 11

There are uncounted numbers of galaxies and solar systems in the universe so it is not unfathomable. However, wormholes are too unstable to travel through safely and the human body could not withstand the pressure of traveling faster than the speed of light. Unfortunately I don't believe NASA will have humans traveling outside our solar system, let alone the milky way galaxy in our lifetimes.
