Time travel question

For anyone trying to get their head around Time Dilation and Mass, watch the film Interstellar.

At one point the crew go down to a planet for a few hours while a bloke stays on board the ship orbiting the planet. When they return to the ship he's spent 30 years waiting for them while they've only experienced a few hours.

Later on in the film they figure out that they can sling-shot around a blackhole to get back on course, the only downside being that the blackhole is so massive that for every minute they're near the black hole a year passes on Earth, meaning when he gets home his Daughter will be an old woman.

It's scientifically the closest any film has actually come to properly depicting "Time Travel".

Why the ability to travel in time would enable you to maybe get 4-5 numbers right in the lottery but not all six.

Are you retarded or something? Or don't have the prerequisite banter or intellect to debate such things without looking like a knob?

If you knew anything of chaos or quantum theory you'd not ask such a dumb f***ing question. You insecure idiot.

Lazy? From The poster child of nothing posts. Shame time hasn't helped you develop better patter.

Was bored at work today and this popped into my head for some reason.

Imagine you invented a time machine in your living room. As time is linear and if you went forward or back in time the machine would stay in the same poition where your living room would be at any point in time . It's well known you can't just visit a particular point as the machine doesn't move only time does .

Now imagine if you went forward and there was a nuclear war and a bomb exploded near your house would you die at the point when you passed that time when the bomb went off or would you simply just pass by it and continue to your chosen date??

I'm thinking you'd die as you'd be at that point at which the bomb went off and you'd die the same as everyone else.

Dunno why I thought of that I just did .

You'd die when the bulldozer flattened your house by your logic
 
The problem with time dilation due to light speed travel is that if you went to the nearest star beyond the Sun using the fastest spacecraft we have at the moment IIRC it would take you 80,000 years each way so 160,000 years to return. Unless you were in cryogenic storage you would never get there and even when your descendants returned it would be to an Earth which which was more advanced than when you left. If you did it at light speed I think it is 4 light years so by the time you returned everyone you knew would be dead, the human race would be super advanced and your spacecraft would be a museum piece.

They did this on an episode of Farscape years ago. The slingshot thing is straight out of Farscape too. Is that whole movie just ripped out of that show? :D
 
It's only likely to work if what we concieve as time travel is actually just a physical movement?

In same way that if you pick up a pen, carry it and put it down somewhere else, it's holds its physical form, the atoms and molecules all come along with it and it's still a pen when you put it down despite the dynamics of atoms inside.

If you took a person and moved it down a tube that somehow physically connects year 2018 to 2021 would it not then mean the person is in no more danger than if walking somewhere normally?

If you create a large enough mass the gravity will distort space-time and you'll experience "time" at a different rate. Earth distorts time enough that the clocks on GPS satellites run a fraction of a second faster than the clocks on Earth. If you could create a huge f***ing mass you could "time-travel" sitting on your arse and literally watch the world go by on Fast Forward.

This is true, however the gravity required would need to be massive enough to be measurable, perhaps from a black hole. The earth would be sucked into a singularity and destroyed, also the observation would be same relative to everyone on the earth before being squashed. The time dialation would only be constrasted if someone transverses away from the gravitational waves of the black hole!
