Is "time travel" possible?

I was surprised to find out the answer is yes to both.
And not the "time travel" that occurs as we move forward day to day.

If you stay on the International Space Station for a year when you return you will have jumped 3.5 seconds into the future!
 
i had to read A Brief History of Time for class, and i got the feeling it's not. since we don't meet anyone from the future now. or soemthing.

i didn't read it 😱
 
any time you move at a faster rate than the other people on this planet you are time traveling

i must wonder how they keep the gps clocks accurate due to relativistic time dilation of orbiting?
 
for all of you that say its impossible.....

please remember if you discussed with someone 1000 years ago the idea of putting someone on the moon they would have said the same thing.
 
Technically it is possible, we think. The reason why we haven't seen any time travellers is because you could only travel back as far as to when the machine was first built. So if you only built the time machine yesterday, that's as far back as you will ever go. Theoretically there may be natural anomolies which have existed for millions of years which could be used to go back farther.

The entire universe is in motion. If you went back in time 1 minute, you would find yourself thousands of miles from the point on the earth you started most likely sitting in the vacuum of space.
 
if i remember correctly, my science teacher from jhs told us that hypothetically, if you could move faster than the speed of light, you could catch up to the images of the past and see what had occurred. although, by the time you caught up, the images are most likely distorted because of light reflections

Right. The idea is that if we haven't met anyone from the future, that it hasn't happened yet.

...or has it...

We no virtually nothing about the universe and how it works and what or what isnt possible in it. To that extent we barely know anything about our own solar system.
Everything they say is a "fact" about the universe is little more than intelligent speculation.
 
Time travel would be nice. At least I can't complain when I spend 5 minutes on a useless thread because I can just get my 5 minutes back. 😛😀
 
sort of on/off topic what if you go 1000 light years away and take an EXTREMELY HI-RES image of the earth and zoom all the way in, you could see back in time...
 
Aren't there some examples using quantum physics? IIRC there is an experiment that can demonstrate a VERY slight time distortion in light.

I've read something on that. Pretty intersting stuff.
