do you think time travel will be possible in the far future?

Question

everyone that says that it wont be because we havent been visited by us in the future, i think we have.
all of those alien sightings that have been reported over the years, thats us evolved.
1. time travel will most likely happen in a space ship
2 if we continue to evolve we will probably look alot like these "aliens" smaller bodies with bigger size brains and heads
3 time travel is possible just not yet

yes traveling at near light speed you can travel forward through time but what happens when you travel faster than light you travel backward through time

Answer 1

Time travel is possible
Today, we know that time travel need not be confined to myths, science fiction, Hollywood movies, or even speculation by theoretical physicists. Time travel is possible. For example, an object traveling at high speeds ages more slowly than a stationary object. This means that if you were to travel into outer space and return, moving close to light speed, you could travel thousands of years into the Earth's future.

"Professor Goddard does not know the relation between action and reaction and the need to have something better than a vacuum against which to react. He seems to lack the basic knowledge ladled out daily in high schools." (New York Times editorial about Robert Goddard's revolutionary rocket work, 1921)

Traveling FASTER then the speed of light? It's possible for mass to travel that fast, however,I think we can one day project electronic messages faster than light...

Anyways, forward travel in time, I think is possible, but backwards? to an event that has already occurred? I think it's more likely that we can go backwards in time relatively speaking onto a parrallel universe... ie, go to a section of universe that has not 'aged' as far as our parts. Stephan Hawking talks about Wormholes all the friggin time now, and how on the otherside is the "perfect universe" while we are floating in the 'junk universe'... so I think we'll need to know what's on the otherside of a blackhole before we achieve backwards time travel.

response to #1: haha, most time travel portrayals are just people jumping through aportal and flying through a tube of colors with no external equipment, save for a portal generator, and some even go as far as use a time jumping platform... but I think you have a point, that if highspeed is neccessary for time travel, then the frictionless vacuum of space is the best place for it.

response to #2: That's an itneresting conjecture, but I think we won't send live things to time travel.. we'll probably start off with junk, if anything. I don't think evolution is possilb ein humanity no longer... evolution=survial of the fittest, but, you know, I'm near sighted, but I can buy glasses to help me earn a living... people with aids and cancer will go on to live productive lives. I think this is it for us, until we develope or are force into an environment or situation where only people of certain qualties can breed, humans from now on will have all the shortcommings and no adaptations. (imagine if we develope air sacs to help filter out smog, gaga)

3: it's possible, but to me the logical progression would be: sending non matter at high speed, sending non matter into future, sending single atoms at high speed, sneding atoms into future, sending small mass at high speed, sending mass into the future, building a general use platform for highspeed travel of junk matter, then larger scale for use by live beings, then people.

Answer 2

Time travel into the future is theoretically possible now. The problem comes from the energy required. The faster you travel, the slower time goes for you. This has been proven here on earth. Airline pilots who regularly spend many many hours per month traveling in excess of 500 miles per hour have been studied and it's been proven that they are a few nanoseconds "younger" than the rest of us. I was reading an article in Scientific American a few years ago and they gave the following example.

Picture a spacecraft launched from earth, headed toward the center of the Milky Way galaxy. During its trip, this craft will accelerate at constant rate, finally ending up going nearly the speed of light. Once at the center of the milky way galaxy it will slingshot around a handy star and rocket back towards earth at nearly light speed. When it lands back on earth, nearly 40,000 years will have passed here, but the pilot will only be 50 years older than when he left.

Answer 3

1. yeah it could be true that the aliens are our great great great great great great great grand kids but they are only allowed to observe and not interfere cause if they do interfere, they will change the future and make a new future for themselves.

2. to evolve and get bigger heads..

to evolve with bigger head, you need to have a group of abnormal humans (mutants) with big heads - sort of like a birth defect which gives them an advantage.

then if something happens to the planet, and new mutants have a better chance of survival while everyone else dies, these mutants would reproduce and soon only humans with big heads will live on the planet, then our species would have evolved.

3. we are traveling through time right now.. forward through time :)

Answer 4

yes. because the the faster you travel the slower time flows. if you travel at the speed of light, time would stop. so if go on a very fast spacecraft and travel at the speed of light for a long period of time when you come back to earth you'll find out that your friends are old people and that you're the same age as you were when you left.

Answer 5

Time travel is not possible for several reasons.
The most important one is if you did try to travel to the past you instantly begin to occupy the same space that you have already occupied. Your mass would instantly double, the density of tissue is twice that which your body can contain, and you explode. The heat alone of having your mass double so rapidly is enough to cause you to burst into flames.

So build your time machine and suffer a horrible death.

Answer 6

Physics gives us the answer to this. It is impossible to travel backwards in time, period.

It is possible to 'travel' forward in time by travelling fast enough, when you are at a high velocity time will pass slower for you than stationary objects so everything outside of the vehicle you are in and the faster you go the more this effect happens. If we invent a vehicle that travels at near light speed it will be possible to 'travel' forward in time.

Answer 7

Time travel exists now, However you have to understand that what we experience as time/space is not linear. Meaning that the past/future you go to is a completely separate timeline and dimension. If you travel back to the past and return, you have not returned to the same timeline you left, but one that is close to it but seperate.

Answer 8

According to physics equation any matter which travels at the speed of light will reach infinity. so time travel for us is restricted by the fact that we are created out of matter.

Answer 9

If time travel were possible we would be swamped by time travelers passing through the present continually!

Answer 10

People will be able to travel forward in time at the rate of one second every second.
