If we time-travelled and changed things, would the outcome be worse?

i was reading about the theory of tenseless time, and basically it says that time extends in all directions, but we simply lack the ability to see into the future, even thought it is already there. as the future is constantly coming into view, it creates the illusion that time is "passing", and events are happening right that moment or something like that... i duno i thought it was interesting. the weirdest thing about it is that everything in the future has already happened, it just seems like its happening at the moment that you experience it. could someone please explain this to me?

yeah. events in the future HAVE already happenned (in the future), but we have just not yet been able to observe them yet.

However, another way of thinking of it is that at every point in time, the timeline diverges into however many ways that the next event can take place (or into as many different timelines as there are possible events).

The future has not yet happend, and will never happen. You are just talking about parallel existences. The theory of parallele existence was created to cover up the dasterdly mistake of having three timelines constantly occuring, which are past, present and future.

past present and future are different points (or directions) in the same timeline (like backwards and forwards on the same timeline), whereas each timeline is constantly diverging, and we are only on ONE of those possible timelines, as there is is a different one for each possibility that might or might not occur.

Time travel is impossible.

But if it were, the future would probably be different every time you went there because the various possibilities.

Well, actually, Einstein theorized that time travel IS possible. The only problem is that in order to do it, you must exceed the speed of light. And when you do that, all matter transforms to energy.

Which is kind of a bummer.

You know, E=mc^2, where E equals the energy, m is the mass that disappears, and c^2 is the square of the speed of light.

Kid's stuff.

Of course, if you DID actually manage to travel to the past, you would invariably change SOME aspect of future events.

That much is certain.

Yeah. Most scientists do say that the outcome would actually be worse then it was before.

You can't control what an effect it will have or how far it will reach. I won't say it'll be worse, sure as Hell be different though.

They only have to find an area that they have proved did not contain any ancestors of the people in the modern world, and then they can do whatever they like and get away with it, as their futuristic technology will be able to cover it up. Like when they get bored, they can just move out and nuke the area, leaving no evidence of their existance there

I don't think they nuke it. That would cause too much radiation. They just move anyone who works out something into a mental asylum, by getting a government order from a future government.

assuming you could travel back in time, this would mean there would have to be atleast two timelines of existence. Changing somthing in the past could potentially completely destroy the present timeline you traveled from to reach the past.

Lets say you went back and killed hitler. The change in the present time you came from, where millions of jews and people were slaughtered could not change instantaneously. you have have 80 year old jewish people appearing out of no where. you would have all the people that died in the war appear out of no where.

Lets say also you traveled back in time and changed somthing that prevented you from being born. this would change stop you from going back in time and changing the events that stopped you from being born in the first place, so the only thing you would have done is erase yourself from existence.

Time travel is an impossible theory. The closest thing we have to seeing in the future and past is the stars

If you killed your grandfather, there would be two realities, one where he was dead, one where he was alive. You'd be in the dead one, where he was always dead. It wouldn't have any affect on the alive one, except that you'd no longer be in there. That's how the theory goes, anyway.

Ah, but he didnt mean that NOTHING can travel faster than the speed o flight. He just meant that nothing can accellerate towards the speed of light. Therefore, things which are (and always have been) faster than the speed of light cannot decellerate to reach the speed of light.

Unfortunately only Quantum effects do that. My theory on how people are going to exceed light speed is that a gravity beam will be fired, bending the space in on itself, shortening the distance and time. Gravity, and negating gravity, are more useful than antigravity as far as I can see.

If we created a wormhole to a part of the galaxy 50'000 light years away that could see earth, then we could sent a MASSIVE telescope there which could look back at the light coming from earth, and see what was happenning on earth 50'000 years ago. Similar methods thousands of years in the future could be used by historians to solve all crimes and mysteries of the past.

Then technically could we not use that same Quantum effects/wormhole theory in reverse to see into the future?

Wooooooooo, find out after the break.

The problem is that you need two worms hole that are formed together or come together in connection. This even is nearly impossible. Besides, light cannot even escape a black hole, how would radio frequencies, or microwaves be able to escape it to be transmitted back to our recievers? If black holes can swallow up galaxies, i highly doubt that anything in the form of matter would survive being sucked into oblivion.

Travel through the wormhole to a point far away in space, then use a spaceship to move to another point in space that can see the light from earth

there are not two different Earths existing in two different times somewhere in space though.

Well, there could theoretically be another earth in the same orbit as our earth but on the other side of the sun

I thought the problem with travelling at the speed of light is that you would need an infinite (or nearly infinite) source of power.
