Answer 1

time is an illusion. we only experience the present at every moment. its our memories and imagination that give us the illusion of time. as far as time travelling, you would always be experience the present moment. lets say you time travelled to 1899 and saw all the funckypeople there and stuff, you would not be re-experiencing a point in time, but just having a pesent experience.

assuming that time is not an illusion, it would still be impossible to physically time travel, i mean empirically impossible. assume you can move one second back in time and you pick up a dollar and then another second and pick up another dollar and do this a million times. you have basically picked a million of the same dollars. but why stop with dollars, why not do the same thing with everything you can get your habds on, why not the whole earth. lets assume you can bring the universe back with you every second you go back in time. now you have a million universes with you at the point you started, whicj we know is imposibl, but my point is, is that this could go on for millisecond or nanoseconds back and forth in time at what point could you chop up time so that you no longer can go forward and back. you cant, it would be impossible to find a smallest point, because your points would go to infinity. but lets aassume u found a point or it doesnt matter, you just go back in time. how do u not keep bumping into yourself when you go forward or backward in time.

if you believe time is real then how do you not bump into yourself going forward and backward in time.? if you can pick up the same dollar a million tims, then you would be in the previous second too, in fact the previous milliseconds and nanoseconds, so how do you keep from getting in your own way. you see theproblem now.

Answer 2

Time is what we use to represent and explain a 4th dimensional element of reality. The 3 dimensions can pinpoint a location of a physical thing (latitude, longitude, altitude), or give a material description of an abstract concept. But time gives its location in the flow of events as they are experienced by us, like another coordinate. Mathematically, you could say that time=change/history. Or, the thing that keeps everything from being on the same page in our history book.

Time is not real because it is a measurement of change. Not a reality. We can only make change in the present, so past is memory and future is imagination. This does not mean that everything is predestined, but that the possibility of every event exists in this moment, which is now. Just like all of the possibilities in a video game already exist in the program, even though some of them may never be experienced. It's us who experience the eternal moment of now, piece by piece, because we live in 3-D reality.

In a more expanded couciousness (like when we dream), we can go to points in time, just like we can go to places. This can happen when your conciousness is free of your physical body. In a dream you can have an event from the past happening in the same room as an anticipated event in the future. That's because there's no time concept. Dreaming is actually a form of time traveling.

Answer 3

Time as seen by Einstein is a fourth but dependent diminsion. Also, It is linear. Time travel is impossible with the current understanding of physics because nothing moves faster than light and nothing with mass can escape our dimensions. I suggest reading:
Time Travel in Einstein's Universe: The Physical Possibilities of Travel Through Time

Answer 4

the coolest thing about time is that it is perfectly relative. For instance, if you fall into a black hole, that is, an area of space with an extremely high amount of gravity, time will pass nearly infinitely slowly, so although falling into a black hole will surely kill you in what appears to you as being a matter of milliseconds, you will have outlived millions of generations of humanity on Earth, for whom time is passing at a much faster rate. There's some other wierd stuff too, but this answers getting too long.

Answer 5

Time is the t-coordinate in the space time continuum (x,y,z,t). For further information, try "A Brief History of Time.," by Hawking. A little bit weighty, but worth the effort, if you're really interested.

Answer 6

Time exists naturally as evidenced by the cycles of the Sun and the Moon yet it is also all in our minds. Personally as much as I enjoy time travel fantasies I believe that we move forward and there is no going backwards.

Answer 7

I waste a lot of it on this stupid forum!!

The only thing I know to be factual about time, is the continued rapidity with which it travels for every year that you are alive! Sorry to not be of much help to you.

Answer 8

time is a measure of change (or entropy)-time is where you are as well as when you are-the earth is spinning at ~1,000 mph, moving round the sun at ~60,000 mph, the solar system is rotating around the galactic center once every (i believe) ~30,000 years) and the entire galaxy is moving outward from the big bang....so exactly where is 9-11-2001?

Answer 9

Time is only relevant to humans because it is based on our position to the sun. In reality of the galaxy there is no such thing as time because it is relevant only to you. It is an invention to explain the lifespan of human beings and seasons for horticulture.

Answer 10

The only way I know of to travel through time painlessly and effortlessly is to take a nap.
