Is Time Travel Possible?

With all the remoaners whining on about Brexit like some sort of perpetual Groundhog day feedback loop, I wonder if time has actually stood still, or gone backwards.
But I wish time would move forward for them.

I think Ree Smogg said 50 years before Brexit would not be a pile of shiite any longer.

I would go back to 2002 and tell myself engaged self how much money I'd be losing in 20 years time getting divorced. I might also tell myself not to sell most of my Tesla shares because the CEO is a spliff head.

Time travel is possible if you compare it to something relative. Traveling faster slows down time as does getting closer to a gravitational pull so if a person was travelling extremely fast and close to a strong gravitational pull, that person would experience time at a slower rate than, say, their twin sibling travelling slowly and away from a gravitational pull.
If this were sustained and each was carrying an atomic clock, the clocks would read different once they were reunited and the twin that was traveling fast would have aged less

GPS satellites travel forwards in time, and have to be continually adjusted.
Navigational errors could be up to 10Km per day.
https://physicscentral.com/explore/...ity theory says,about 38 microseconds per day.
So yes, time travel is a daily occurrence.

The centre of the Earth is 2.5 years younger than the crust due to time passing slower at the centre

That's not time travel though, that's the relativity of time.

I think that is the point, it depends where time is observed from. Physics dictates, currently, that you cannot go back in time but time can slow down or even stop for something travelling at high speed or subject to a strong gravitational pull. To the "people" that time has slowed down for, it would seem that the people not subject to speed/gravity have traveled to the future.
The weird thing is, the satellites mentioned really are younger, by micro or nanoseconds than the observer that noticed the atomic clocks showing a perceivable difference. That being the case, if the observer was on one of those satellites, we would be experiencing things in the future by a similar amount. so we would have traveled forward in time by their observation.
Time travel never has been and never will be possible.
The speed of gravitational waves in the general theory of relativity is greater than the speed of light in a vacuum, c.[3] Within the theory of special relativity, the constant c is not only about light; instead it is the highest possible speed for any interaction in nature. Formally, c is a conversion factor for changing the unit of time to the unit of space.[4] This makes it the only speed which does not depend either on the motion of an observer or a source of light and / or gravity. Thus, the speed of "light" is also the speed of gravitational waves, and further the speed of any massless particle. Such particles include the gluon (carrier of the strong force), the photons that make up light (hence carrier of electromagnetic force), and the hypothetical gravitons (which are the presumptive field particles associated with gravity; however, an understanding of the graviton, if any exist, requires an as-yet unavailable theory of quantum gravity).
Nonsense, it's happening all the while with fast moving satellites.
From this link..........https://physicscentral.com/explore/...ity theory says,about 38 microseconds per day
"Also, the orbiting clocks are 20,000 km above the Earth, and experience gravity that is four times weaker than that on the ground. Einstein's general relativity theory says that gravity curves space and time, resulting in a tendency for the orbiting clocks to tick slightly faster, by about 45 microseconds per day. The net result is that time on a GPS satellite clock advances faster than a clock on the ground by about 38 microseconds per day."
Time travel back in time is only feasible in theory and that is an unmitigated fact!!!
Good evening

Dunner be daft.
Understanding of this, would appear to be way above a builders pay scale.
Thankfully though for you, your pilots knowledge of this got you home safely.
