Do you think that its possible to create a time machine?

Question

In the past said that it was impossible for People to go to the moon or into outer space, but Neal armstrong proved them wrong. Do you think that its impossible to go back in time? We had a discussion about this in class, so i was just wondering...

I meant to say "In the past, people said that it was impossible......"

Answer 1

The very concept of a time machine is a bastardization of what time really is. It is not a true dimension that we can go up or down, back or forth in. It is the progression of events, and nothing more.

The problem is that we quantify time as if it is a dimension. Time never changes. Only our perception of it.

Time travel is nothing more than pure fantasy and no where near comparable to landing on the moon.

Answer 2

Traveling forward in time is easy. We already travel forward at 1 second per second right now, but that's not what we are talking about. Moving at a different speed also changes relative time (much more as you approach the speed of light) but you can never go 'back' in time.

So, moving forward isn't difficult. Traveling fast, being frozen, etc are all possible, if technically difficult or expensive.

Moving backwards in time is much more difficult. We know of a few theoretical machines that could possibly let you go back in time, but only to a point after the machine was built and turned on. Usually these machines involve black holes, wormholes, dark energy, or other concepts that aren't fully understood. On the plus side, these machines haven't been proven impossible yet. Most of the theoretical machines do require abilities that are far beyond anything people can do today - things like manipulating the energy and mass of suns, travelling through interstellar space, manipulating black holes, etc.

A machine like the Delorean in Back to the Future is probably not possible. To go back to a point of time before the machine exists and manipulate anything or to send any information back is considered unlikely or impossible with our current understanding of the universe. The best you might be able to hope for would be the ability to view, but not affect, the past.

Of course, you can already look back in time - when you look at the sun (hopefully not directly) you are looking 8 minutes or so into the past because of the time it takes the light to get to the Earth. Some of the light we get from stars is thousands or millions of years old.

Answer 3

If you built a time machine to go back into the past, the very first instant of your trip you are occupying the same space that you were just an instant before, your mass doubles instantly creating a rapid rise in temperature and you basically explode. End of trip. Time travel to the past is impossible.

Answer 4

I think it may be "possible" with the assistance of some exotic physics that may or may not allow time travel to work.

However, it will either prove to be insanely expensive or require super-gigantic amounts of energy to accomplish, or both. A working time machine, therefore will never be accomplished.

Thinking it out logically--IF someone in the far future succeeds in building a time machine, then why haven't we seen visitors from the future. Why wouldn't those people try to "fix" tragic events in the past, leaving some trace of their meddling?

Answer 5

How can a person recreate a dimension of time through history? The only factor for time travelling is travelling forward which it is constant. It is not possible for NOW, but it may be possible LATER. It is not possible because Man cannot redirect or reverse time to its backwards state. It is through imagination to control time but not in reality. That is baloney! The future Albert Einstein might solve this issue. Have you ever heard of an John Titor?

Answer 6

Well to say that becuase we have seen no one from the future and conclude by that time travel is impossible is incorect. I think that there would be a law that makes them have to blend in and not say anyting about time travel. But anyways I think that we could up with somthing but only to send messages back like by radio waves.

Answer 7

To travel in time gives us two options: forward in time and backwards. If we were able to travel backwards, there would have been somebody from the future already or not? But nobody has come sofar, so we can exclude that option. To the future, yes we should be able to. Travel fast, and time goes faster for you then for the ones staying behind. You can also freeze yourself and when you wake up every everybody has turned old. I wouldn't advise you that: it too cold! Take care!!

Answer 8

It may be possible, but probably not in the way we'd like. If time travel was ever invented it would eventually become cheap and affordable technology and everyone would use it. We would then have all sorts of time-tourists crowding our streets. On another note, watch the movie PRIMER. It is a pretty nifty take on time travel.

Answer 9

The glitch that I see is going back in time before the machine
existed -- what would happen ? Don't think it can be done
unless it was totally a mental trip using the abstract that
we really don't know anything about.

Answer 10

If it could be done,it would have been done.
Time machines would be more popular than cars in all eras of the past and the future.
