Time travel is impossible because time is not real

Time and space are composed of the same aether base "material". Time is this aether as kinetic (infinitesimal Singularity engaged in infinite velocity AND AT infinite angular diversity), Space is this same aether as static (the infinite expanse cause by the "wake" of the Singularity kinetics)). Our realm is percentages of both - spacetime.

Time is physical property of the universe, not an illusion. humans only created a standard way of measuring the passing of time.

Space and time are physically intertwined. If you move through space at the speed of light, time stops. Say a man travels for a year at near light speed. He returns to earth after a year and yet on earth hundreds or thousands of years have passed. If time was just something humans created, then speed should have no effect on the passing of time and it would mean our minds are capable of physically changing the passing of time.

Time travel to the past is what scientists say is probably impossible. Time travel to the future we know is possible. First off, time is not a constant and is linear. Time only flows 1 way but the speed of that flow is relative.

Einstein is the one who figure out that The faster you move through space, the slower you move through time. Time stops when you reach light speed. Moving faster than light would bring you into the past but since nothing can travel faster than light we cant travel to the past. Large Masses also bend space and time which slows down time in that region of space so if you were to orbit a black hole for a year, hundreds of years will have passed for anywhere outside of that orbit. This is fact. Our satellite gps system relies on this knowledge. Earth itself slows time just a little bit. The closer you are to the center of mass, the slower time moves. The clocks on satellites need to account for time being slightly faster in orbit or our gps systems would be totally innacurate within hours

Edit: And the word theory is terribly misinterpreted. In physics a theory is the most complete and formulated understanding of a force or law of nature. It means a flaw has never been found. The theory of gravity. The theory of thermodynamics. Etc... Nobody doubts the existence of gravity. Theory is just the term used. Humans wouldn't be here right now if we refused to learn from others and only learned through our own experience. One of our greatest strengths is being able to attain knowledge from the experiences of others and fron those that lived before us. The story of human progress is facinating and if you take the time to look into it you can see how we came to our current understanding of the unverse. Not everything is a lie

Thank you for taking the time and putting the thought into responding. It doesn't really change anything I've said though... And I'm not convinced of anything more.

Time is relative. One year -- one rotation of the planet around the sun -- is much different on Mercury than on earth, and much different on Pluto than earth or Mercury, and so on. The fact that the tools we use to measure time changes by circumstance and outside factors, or does not function the same in one set of circumstances as another, does not change "time." Perspective is everything...

But there is also no way that we could travel to a place or time that has not yet happened, so no, I don't believe for a minute that we could travel to a future that does not yet exist.

Look around now.... now find this thing called time.
Show me time.

All you will find is movement occuring presently.

I see time as movement and nothing else. Without movement there is no time.

Nuclear decay doesn't seem to require any particular movement, yet it's one of the ways we measure time, so you might want to re-think that.

We measure the age of dead plants and animals using carbon-14 decay and measure the age of the Earth using the decay rates of other various atoms/isotopes.

When is the decay watched/studied?

Studying and watching and observing happens presently.

The observer must be present.

Past and future will never appear.....except in stories made of words appearing presently, and they disappear as they appear.

This is well-studied, so the fact you haven't studied it doesn't make it any less valid and merely indicates you have some catching up to do if you want to understand it. Here's a link you can start with if you want to learn. No motion is required, but the literature on this phenomenon is quite extensive so there's a lot more to read if you want to understand it.

Basics OF Radioactive Isotope Geochemistry

Since a radioactive nuclide decays to its daughter at a rate independent of everything, we can determine a time simply by determining how much of the nuclide has decayed. We will discuss the significance of this time at a later point.

So, how do time crystals work?
