Is time travel possible?

Is our future already determined as to what we are going to do?

The past and future should have the same characteristics but only in revers direction. If the past is set then the future is set. However, in general, change is the rule of the cosmos, we do not live in a steady state universe. I believe that the past and future are in flux and undetermined. Tell me something that proves that the past is set in stone.

Because of things we've already done?

Using the manmade convention of measurement we can mark things that happened. And if the past isn't set then these things that happened would be subject to change and might not have happened. Like the london Bombings back in July. If the past was not set then there would be a chance for that event to suddenly not have happened. Or the Titanic. Seeing as how those people have died, and we can look at recorded history. If it changes so it didn't happen the people that died would have to pop into existence. . .

However, the effect of a cause radiates like ripples on a pond. When an event takes place (cause) the result (effect) changes the present and that change becomes a cause that has effects that cascade in the present. This causal relationship only travels in one direction, from cause to effect, therefore, retro-causality is not a problem. Again however, retro-causality is a possibility in string theory, but has never been observed in nature.

What we do in the present does not effect what we have already done.

If I get dirty, and I take a shower, taking the shower means that I am no longer dirty, but it doesn't mean that I was not dirty once.

I'm sorry, you must of not understood what I said. Reto-causality has never been observed in nature.

If you take a shower, that creates change that happens now; when you talk about the time you took a shower, you do it now; when you remember the shower, you do it now. The fact that you are clean is because the show made an effect that made a cause, that made an effect... the result is now. The shower you took does not exist.

the flux capacitor is what makes time travel possible

The only way that one can make a time machine is to have two wormholes that are connected and a ship that travels near the speed of light. You take one wormhole and put it on the ship and send it into space at near the speed of light for a number of years. The other one is left here on earth. The ship returns, lets say after 20 years, you can then step through the wormhole and go back 20 years. Easy...

yep, easy as pie chef

Ya, wormholes are easy to find, if you water your lawn, then late at might, you can go outside and find then in your lawn. 😆

The shower I took does not currently exist, however when I was taking it it did exist. It simply ceased to be. But that does not mean that it never existed.

"But that does not mean that it never existed." Correct.

The problem is, thinking that things still exist in the past, therefore, we can travel back and relive them.
If time was to suddenly change direction, but causality where to remain the same, would we notice any change? The reason I ask that is; how do we know that time is flowing in one direction? What if it was oscillating, rapidly moving forward then backward over the same moment?

It's a dimensional thing....time is within time...that is within time and so fourth...

Or is that called dementia? 😑

That would explain why when I make a calculation and it works, then I rerun the calculation with the same numbers it doesn't, and then works agin the third time. . . and I'm talking over a spance of . . . well time. . .

Lets say you and I set our clocks to be the same, I then get into a space ship and blast off. We also have special magical cameras that will allow us to see each other instantly, regardless of the number of light years between us. I set the speed of my ship to be close to the speed of light. When you look at me throught your magical camera, you see me begin to slow down as I get closer to the speed of light, my clock also runs slower. From my perspective everything is normal, but when I look at you through my magical camera, you are moving really fast and your clock is spinning. I return in one year my time, but 5 years have past on Earth. I am in the past to you and you are in the future to me, but we stand side my side with no problem. If there was a past and future we would not be able to see each other.

This is true.....and it has been proved that the further out you are in space, the slower time lapse...It has been documented.

If entities from the what was past cannot be seen...maybe they are still there, but in a different (time dimension)...But some people can see them....what do ya think?

Sorry it's not the further out in space, it's the faster you go. A test of the theory of relativity has been done. Two atomic clocks were used, one was on earth, the other was placed in a high altitude aircraft that could travel at ~mock 4 or 5 (I don't recall the particles). When the two clocks were reunited there was a slight difference that was equal to what was predicted by the theory.
