Do you think time travel is possible?

Hey everyone

This has been bugging me the past few hours... no matter how much I try and think of something else I can't get this out of my head!

I'm just going to throw out some scenarios and let you all discuss...

Say in 100 years we make time travel possible, and we send someone back in time. Say that person meets his "past" self and gets into a nice chit-chat about time travel and the past self decides not to engage in time travel. When the time comes and that person does not go back in time, the whole future from that point on would not exist because of the first person to go back in the future? So it ends up in an infinite loop that we have no knowledge of/can't get out of...

Here's another point... although it may not relate to time travel...

Because of the sheer distance between Earth and our closest star, it takes millions of years for a twinkle of light to reach our eyes. Lets say since that tiny beam of light has left the star and traveling towards Earth, the star has exploded, a huge firey ball of death maybe heading our way at light speed and we wouldnt know about it.

Only the speed of light in that has something to do with time travel, now imagine this. If we ever manage to go faster than the speed of light, we would (theoretically) get to our destination before we left. Now this presents obvious problems, like killing a person or maybe even making an exact clone of them.

Also, for traveling forward in time there we would need to have our future planned for us to some point, which starts all the religious arguments about God existing etc...

What do you think?

 

They say its possible in theory to travel forward in time but not backward. If you were to travel at the speed of light for say three years then come right back, only two weeks will have passed or something like that.

 

Everything from the past had been destroyed and everyone from the past
has died. It is impossible for them to live again just because we do time travel.
That's my opinion.

 

Not a chance in hell...space/time holes only exist in elite movies like Jumper.

 

Because of the enormous size of the solar system, we have not even explored our 9th planet. And the solar system is a mere grain of sand in the galaxy, and the galaxy is a grain of sand in the "known" universe. That being the case, how can we possibly assume to know anything with certainty?

 

Its actually the opposite.

 

i dont think so .. at least thats what i believe

 

i don't know.

 

I think it is possible. I read somewhere that they are already making a machine that can send small particles or something forward in time. I also read somewhere else that some man has already traveled ahead in time like a fraction of a second because he was in the international space station for a long time. Interesting, but I think its another 100 years before we fully understand the concept.

 

Ok, if traveling to past is possible, lets say after 500 years, the first time traveler oes back in past and arrives in Year 2008, July 23rd, thats today.
How do you consider we are moving ahead with time, we could be actually going backward in time.

 

It could be possible by freezing someone and defrost it in the future...

 

in common logic its not possible, but we human didn't prevent lots fact about this world

 

Yeah, time slows down for the person traveling near the speed of light. That really is time travel, it's just not the type of time travel we think of when we think of the term.

 

i think it's impossible.

 

100 years ago, going to another planets is impossible.
Who know time travel will be possible in the future

 

Who are the future time travellers among us? More theoritical proof exists for the future time travel than the past time travel. Past time travel creates lots of paradoxes and changing time line. I even don't think in 100 years we will understand the time travel better than we do now. In 100 years we will certainly move to a type I civilization and we will have more space travel. To understand time travel we need to move our civilization to Type III civilization which is some 70,000 years away.

 

Anything is possible, just think... people used to believe that the earth was flat and that everything revolved around the earth you never know

 

People used to ask this same type of question, but in regards to going to the moon or traveling faster than the speed of sound.

So my answer would be "yes".

Just as smallmerchant said, there is no way to be confident and say that we can't, when we hardly even scratched the surface of exploring our environment or our universe.

 

my question to present is: if you did travel forward in time, you might know. but how would you report it back to the people in the present?

so it might be possible that people have traveled forward in time, but no one told us that "it worked!"
