If someone went back in Time and changed something, he would be the only one aware of it.

Good point and one of the most probable. Also we could hop in and out of various dimensions and it would be like time travel. I'll take the one where my wife and I have a good seat for the Trump Second Inaugural in 2021, watching the smiling new GOP House Speaker and Senate Majority Leader who replaced Mitch.

Although I gave up SF after actually writing about it, reviewing and interviewing for years and getting published, time travel is about my last holdout interest. I have probably thirty-five books on it (amazing there are that many) plus about 50 or more novels and collections of short fiction.

Short of direct help from above, time travel would be about the ultimate power one could have.

But will it answer the ever pervasive riddle if yesterday is tomorrow’s today then what does tomorrow’s yesterday make for dinner? Spaghetti or lasagna?

“ No one has yet managed to travel through time”

We all do it every single second.

I have simple tastes. Just time travel a day ahead to get the Lotto Drawing Numbers and then go back a day.

Or go back a week or so and buy Gamestop.

Mathematicians make the mistake of believing anything they can do mathematically can be done in an empirical material manner; yet empirical science is always proving theoretical mathematics wrong.

So if you do successfully travel back in time, it’s just groundhog day.

That timeline already exists. All possible timelines exist. The mind of God level stuff.

Every record has been destroyed or falsified, every book rewritten, every picture has been repainted, every statue and street building has been renamed, every date has been altered. And the process is continuing day by day and minute by minute. History has stopped. Nothing exists except an endless present in which the Party is always right.”

― George Orwell, 1949

Fortunately, it has proven for all times and all places and all universes that mathematical formulations have an exact one to one correspondence with the outside world....

Oops....

Basically I thinks it boils down to the universe is HUGE and just doesn’t care if 1 person somehow becomes “impossible”. Billions of people on the planets, billions of planets in the galaxy, billions of galaxies in the universe. 1 person goes back in time and kills their grandfather, so what. It’s like a physically impossible grain of sand on the beach, who’s gonna notice?

"The past is over and the future hasn’t happened yet; there is only the present."

Yup, I've been saying for some time (ha) that time is a human construct.

"Doesn’t really matter if I can go forward or backwards in time, if the where of the when is in the middle of empty space when I get there. In order to travel through time, you have to be able to accurately and effortlessly travel through space."

Right. You could wind up in the depths of a star or nowhereville. The calculations to arrive at the where in your chosen time frame are probably impossible.

His theory only works in a system that is completely and absolutely deterministic.

From what I understand, quantum mechanics tells us that the universe is NOT entirely deterministic, at least at very small scales.

You need a TARDIS.

The fact that everything in the universe is always in motion is the biggest failure of most time-travel stories.

Homer Simpson gave that a try awhile back. It lead to nothing but trouble. But maybe Homer just isn’t very good at math.

Is that a problem?
