People who genuinely think Time Travel is possible probably also believe in Unicorns.

However, this kind of manipulation only affects the rate at which time moves forward. No matter your speed, time will still progress toward the future, leaving scientists struggling to predict how one might travel to the past.

It's very simple, actually. We just have to reverse the polarity of the neutron flow...

actually, you're not... the earth is moving through space at whatever speed it goes around the sun, which means that one second standing on earth is actually slightly less than a real second would be if you were floating in space, not moving...


How fast is the galaxy moving?

I'm just going to have to see it to believe it.

Well then, just look at Hum, he's from the past. Don't believe me? How do you think he got here?

If you are in the States go to the Georgia/Alabama state line and go back and forth.... You have time traveled one hour forwards and backwards :laugh:

If you went back in time it would be impossible to change the future that we live in now.


Ever heard of alternate futures? Plausible? Maybe. Impossible? With what we know now? Yes. I personally don't think we could change major things like killing Hitler before he became leader of the First Reich or preventing JFK from being assassinated. But I think we could possibly change our own personal outcomes.

Influence our own selves to make different choices. But, I am not a theoretical physics scientist.

Well, there is no such thing as a "real" second as there's no one "real" reference frame.

Allow me to restate my post:

I'm I'm time travelling now. Although, it's at a rate of one second per second into the future like everybody else on Earth...

I time travel every day. I just close my eyes and BAM! I'm 8 hours in the future. Sometimes only 6 or 7 hours into the future. Depends really. It's fairly inconsistent. ;)

well going forward in time should be technically possible, although very unlikely to ever happen in our lifetime, it still is possible. Its going backwards that shouldn't be possible.

Even the concept of time travel is an invention of mankind. It's like magic and the tooth faery. It doesn't exist.

Ok I'm about to attempt to travel back in time and If I'm successful, Germany will lose World War 2, England will win the 1966 World Cup and the Monday will be AFTER Sunday.

in that thread, lots of people acting like they know what they're talking about and trying to appear very sure of it.

Isn't time just motion relative to other motion? If nothing ever moved, would time exist?
