There's a simple logic game that -in my mind- proves time travel is possible , despite Hawking's famous quote:
“If time travel is possible, where are the tourists from the future?”
1. Time travel math/physics have already been elegantly worked out - Tipler, Wheeler, even Feynman! - so that's it's NOT unreasonable that a time travel device (which would also double as a hyperdrive of course!) WILL, eventually, be engineered. And no, I don't think the weird paradox posed by some that time travel devices could not travel earlier than CERN creating the 1st microsingularity is valid.
2. Therefore, a time travel machine has ALREADY been built, and visited many worldlines. the Graham-Wheeler-Everett multiverse allows a time traveler to indeed go back and speak to himself or his ancestors - as they aren't the EXACT ancestors that exist on his/her own worldline... - negating the grandfather paradox. There are moebius strip like flow-charts that can be derived when worldlines interact...quite complex.
So, Hawking is right in a sense - we sure have no concrete proof of any time traveling tourists, yet... Would the average citizen be able to time travel (ever?) - NO.
Would a government have ultimate control of time travel devices - YES.
Would time travelers then reveal themselves outside of their time? Very likely not.
So once we figure out the secret to gravity - as it relates to the "graviphoton" - AND we have access to immensely (compact) energy sources (ie., microsingularities), then we will be able to manipulate time.

In my personal opinion, physical time travel just isn't possible. As a previous poster said, it is possible to observe events from the past, but obviously not the future, because those events haven't happened yet.

call me crazy but i still think Titor wasn't entirely a hoax for the simple reason that his knowledge of high energy physics was just too dense. Either he was a high functioning pychotic or he was telling the truth. His version of a time distortion device had 2 mini singularities (sub-electron size) being "injected" with electrons, "revving" up their ergospheres such that they would interact at a certain radius to produce an einstein-rosen bridge. a real high energy physicist would be necessary to validate your hypothesis that the electrons jumping shells are doing so in a 4th dimensional fashion, but it sounds to me (not a physicist, just a neuroradiologist) like Quantum entanglement . . . ie., the photons are carrying information about their states across great distances instantly - which in effect is a stargate like phenomenon. All this without doing the math!
nice intro to photon-atom interactions...

I'm not sure this can be an absolute statement of fact... Is time linear? Our perception of time is but that might just be consciousness interfering in it's own basic way.
What if all things are happening at exactly the same time?
Does the electron exist in two places/times yet our conscious perception is only able to translate what we 'see' into a movement/teleportation?

i do like the consciousness angle - but it seems recapturing ancient meditation techniques may prove far harder than brute force opening a stargate with microsingularities!
The multiverse theory also includes shroedinger cat like aspects of conscious perception affecting the outcome of quantum states, so I buy that angle.

If the field affects the view from the interpreter would that mean if time is an "illusion" then the events of the past can be manipulated, because technically they're still playing out?
Exactly and all the possible probabilities as well .Multiple Universes as multiple interpretations, parallel synchronistic call it what you will. A very highly energy efficient way of organising things. Matter and reality being a conscious interpretation of the local space time environment.

I agree... but its an energy thing man... How much energy does a black hole have? How much energy would be released in a tear in the fabric of time and space??? More than any known materials could withstand.
That and if you gave a population of monkeys water gun technology.... you would see it. Hawkins was right... we would see our monkey descendants by now coming back.
