In 2020, is there any advancement at all in potential time travel?
I read some promising things back in the mid 10s, one by an American professor Ronald Mallett, that he thought we could go back years ago.
Is there any advancement on this? Could be go back to 2003? 1994? 1BC? I am plucking these years at random but just any time?

We are always traveling through time. If you want to travel faster, move to either a higher elevation or someplace in outer space. If you want to travel slower, move to a lower elevation or some other place with more gravity, or run, or catch a ride in a spaceship.

Wait a minute... now its the future. LOL. No, nothing new that I am aware of. Even the latest ideas about sending a postage stamp sized probe to alpha centauri... while it might reach 20% the speed of light, any effect of time dilation would only be experienced by astronauts riding on that postage sized probe. Right now this is just not a thing we can do. The only reason why they think they could get a probe up to 20% of the speed of light is because its mass is so small and still it would take an array of lasers several square miles in area to propel that tiny mass with its solar sale to that speed.

The only thing you can do is travel fast. Your time will appear to slow down compared to others the closer you get to the speed of light.

Yes. A major breakthrough was made, but it was accidentally sent back to 2001. So now if we can only figure out how to travel back in time to 2001, we'd be set.

Time machines can only ever be discovered, not invented. Astonishingly, although it constantly recedes from plausibility by particular methods, nothing ever seems to rule out time travel.

It is becoming clear that one of the most fundamental laws of physics is that "causaility is not violated" --- in other words, once an event happens in spacetime, it cannot be made to "unhappen". This result appears as a side result of both Quantum Mechanics and General Relativity, and it may be more fundamental than either of those theories. If true, there is no "going into the past".

nope, nothing promising is going to happen anytime soon

No. None at all. Time travel is science fiction. Even to try to do it would involve manipulating gravity and wormholes and stars and black holes. Our technology is millions of years away from actually trying to build a time travel device.
I know Dr. Mallett is a serious physics professor who is interested in time travel research. But that is more theory than experiment. He wants to see if it is theoretically possible or not. He has tried some lab experiments too, but he doesn't have near enough power to even send an atom back a nanosecond.

The past is a completed action. Think of time as a sand castle on the beach. You have built this castle and now you decide to demolish it. You now decide to rebuild it. There is a slight problem. In the demolishing you moved the grains of sand around. While your new sand castle looks like the original one it is a brand castle because not all the grains of sand are in their original places. It's called entropy.
The future is different because the sand castle has not yet been built.
