is it possible to enter another dimension, travel into the past, or end up in a parallel world?

Question

If one goes really deep into space and gets lost, stranded, enters a wormhole, whatever, is it possible that we could end up in an Earth where say for example JFK was never shot and died of old age? Or how about ending up in an Earth where the Axis powers won World War II?
How about traveling into the past? Is it possible to land into an Earth where its the time of the Roman Empire, or the time of Jesus Christ? What about landing in a future Earth where the year 3000, or 4000? Is this really possible? I know it sounds crazy, but given the complexity and vastness of the Universe, is there a remote possibility that this could happen?

Answer 1

Definitely possible when you are in your dreams and you are Captain Picard

Answer 2

some people would not find it strange I think it could be not a possibility to enter another dimension, travel into the past, or end up in a parallel world if you want

Answer 3

Many people will jeer it off as extremely hard but I suppose it could not be probable to enter another dimension, travel into the past, or end up in a parallel world

Answer 4

Many people will flout it off as unattainable but I believe it might be imaginable to enter another dimension, travel into the past, or end up in a parallel world

Answer 5

to enter another dimension, travel into the past, or end up in a parallel world simply cannot be possible

Answer 6

There are many theories behind time travel and alternate realities. Most believe time travel is possible but not in an unlimited sense. If a time device were created now, then future you could only come back to when the device was activated and formed the rift that you would travel through. Worm holes are something else all together. One thought is that once you enter a hole it has many exits and you can be thrown out at any time from the point the hole was created until the point you entered the hole. There is no hard set theory for traveling to the future that I have come across. Only some half baked ideas with no physical science behind them. As for alternate realities, there is no basis to believe they exist at all, they are simply an invention of science fiction. Though time travel does not yet exist there is at least a basis in science for the belief.

Answer 7

Entering other dimensions, traveling into the past, and spending time on parallel worlds, are things that are reserved for politicians only.
Scientists have not figured out how to perform these functions yet.

Answer 8

How to enter dimension
we live on 3d world all you need to do is apprehend the 4d or so but the mathematics concludes there are just 11 dimension.Picture this out we are only trap on 3d world,all you need is 4d space time way or worm hole.Our space is 4 dimension and so is our black hole.You need rip of our cosmos and another rip to other dimensions to get the hell out and also theory concludes that gravity can travel through every dimensions easily so you need to collect gravity particles or gravitons to carry your ship on higher dimensions.

How to travel into the past:
you need an infinite cyclinder that is rotating to perform time loop event.Time loop has past time travel limit or beat the speed of light to reverse space time slice relative to the universe.

How to end up in parallel world:
it requires wormholes to the other universe

Answer 9

Some scientists/physicists think it is but personally I do not. All atoms are constantly decaying and the Universe is expanding. Meaning time is always moving forward. In order to time travel a person would have to turn back the time of an atom's decay and if he were to go through a wormhole the wormhole would just put the person into a different field of the Universe. Since the Universe is expanding at thousands of kilometres a hour no force within the Universe can stop the galaxy from moving away from the Big Bang and move back in time. The person would also have to effect the mechanics of a galaxy in order for the planet to be at a certain orbital point within the galaxy at the time he wants to go to. So, I think it is impossible that time travel exists.

Answer 10

According to modern physics it is 100% possible, it is just very, very improbable.

Individual parts of your atoms do this all the time (the time travel bit, not the change history stuff). The reason you don't travel back in time is that individual bits are alsys coming forward in time or just staying put so the net gain in time travel is zero. Now, if you cold get all of your subatomic particles to jump backwards in time at the same time and velocity, you can travel back in time. Easy-peasy.


Same thing with alternate dimensions, etc. All possible, just not probable.

Answer 11

Yes, absolutely, anything is possible. Even though achieving these lies just beyond the normal circle of experience for the majority of ppl. Saying no or that it is not possible is entirely inaccurate and close minded.
