Time Travel?

We all know that science-fiction creator and people with imagination from long time was playing with Time Traveling and things like that. Let's say that one day people will create time machine that will allow you to travel in time to any moment in history of earth. Who would own such a device? What right to use will he have? Think about it even a single change in pass can make a TERRIBLE changes in future. Will a single country or a man could just keep it for him self only?

For example going back in time to the moment in history helping your country would make future totally different and no one would remember you after you get back because you would never born.

Another thing is that we could be visited by people from future that already build time machines. They could move them selves in to the pass becoming famous people that we know as great people of history. Maybe our history is already changed by someone?

Think Like Einstein:
Albert Einstein showed that space is curved, time is relative, and time travel is theoretically possible. Here, do a simple thought experiment and learn to think like the century's greatest scientist.

Who would have right to Time Travels?

Discuss.

Jam it back in, in the dark.

And what about the future? You think that government will only stick to history purpose adventures? They will want to travel in to the future and find any new weapons that they can use against others.

With all this terrorism around even in well guarded facility time device isn't safe. Then only one question is left: Should we even try to create such a device?

There's nowhere I can't reach.

I think that time travel and parallel universes are not so similar things. To travel in time you need time device to travel through parallel universes you need to find portal or gate to it or create wormhole to it like in Sliders.

As for the time travel there was idea of traveling in space in time. Maybe trawling in time is just way of finding right wormhole to the parallel universe that present earth in certainty time period.

IF time travel would exist, human should think of a way to discover history without letting anyone see him. Some cloaking device or something.

Time device should be small so you can take it with you or it should be a vehicle that you can travel inside. As for the place you will land there need to be some static point that everything else will be depending like sun or star. That's how you will know exact coordinates.

I am a dolphin, do you want me on your body?

So after all this we come to the conclusion that even if someone will invent time travel it's impossible to travel =D You never know where you will land or what will see. There is no static point in universe and it's still growing. Besides if would take years to make calculations of earth position few hundreds years earlier.

I was speaking idiomatically.

It's a fun concept to wrap your mind around, but it'll always remain science fiction.

Then what about Black hole?

Space-time distortion and frame of reference

Quote:

Objects in a gravitational field experience a slowing down of time, called time dilation. This phenomenon has been verified experimentally in the Scout rocket experiment of 1976, and is, for example, taken into account in the Global Positioning System (GPS). Near the event horizon, the time dilation increases rapidly. To the distant observer, a falling object's movement slows down, approaches but never reaches the event horizon. Any escaping photons do not slow down when escaping the gravity well but experience redshifting. From the falling object's frame of reference, it will cross the event horizon and reach the singularity at the center of the black hole within a finite amount of time.

So if time can get slower then maybe even can be stopped or turned back? Using this maybe we can even make it go faster? Think about it.

What kind of toxic man-thing is happening now?

BTW, your analogy sucks.

Time changes and technology goes foward soom things that are impossible now will be normal stuff. So everything is possible =)

FELIPE NO
