One of the fundamentals that underpins not just physics but every aspect of existence is the law of cause and effect, always in that order. Changing the past would violate that: your actions would affect what caused you to go back in the first place – so if you did manage to kill Hitler he wouldn’t have done what led you to go back and kill him.
That doesn’t stop filmmakers exploring the consequences if you could somehow drop in on history. For Hollywood, applause and special effects are more important than cause and effect, and time travel offers unlimited opportunities to push both imagination and CGI to their limits. Hence screen time machines have included a police box (Dr Who), a phone booth (Bill & Ted’s Excellent Adventure), a DeLorean sports car (Back to the Future) and a big nudes-only energy ball (Terminator).

They always travelled to the past and made good use of movie footage spliced in from Hollywood movie productions
Even better.
Forget shooting Hitler,
If I ever get a time machine I am going after woodrow wilson...
He sort of has it right.
You can visit the past, but in doing do, you have created a new timeline going forward. You cannot return to your original timeline. The new timeline may be similar, but because so many events turn on what amounts to chance, the further back you go, the more unrecognizable your starting point will be should you ever return to it.
There is a coherent “real” timeline, we may or may not be in it, that “created” timelines either merge into at some point or branch away from entirely. What happens to those branching timelines is the stuff of fantasy and nightmares.
“in doing so” not “in doing do”
Proofreading and morning do not go together.
That was the one episode I remember and this show has hardly ever been shown in reruns since it only lasted one season and you need a certain number of shows to get any sort of syndication deal. So I went to wiki and all the episodes are listed and 3 of the 30 episodes went into the future.
There is something else that is never addressed. Where we were in the past in terms of space is very different to where we are now since the earth /solar system/ galaxy and who knows what else are all in motion.
I doubt that. Would you care to cite chapter and verse?
Regards,
well three out of 30 is better than none out of 30. i loved the show as a kid, and have both seasons on dvd. haven’t finished watching them all yet.
Episode 2: One Way to the Moon." Tony and Doug travel to the far-flung future year of 1978!
Episode 24: ""Chase Through Time." Tony and Doug travel to A.D. 1 million.
Regards,
Episode 30: "Town of Terror." Tony and Doug return to the far-flung year of 1978!
Regards,
Ok to get nit picky 24 is only partial since two other times are visited both in the past. Ep 28 goes to 8433 AD so the total of future visits is 3 and 1/3 episodes out of 30.
I'll always make sure to be carrying one of these, just in case.
Paradox is not possible, imho. If it can be done it already has been done. Your future self is predestined to do so, if you traveled back in time.
I remember a Science Fiction short story about a man who had invented a time machine, which of course needed lots of energy. He planned his first trip to begin at the local electric power-plant, which was closed for generator maintenance.
The departure point was from within the shell of a giant generator whose rotor was out for maintenance. The trip was supposed to last for two hours. When the man did not return by the next day or week or month, his engineer friend assumed that he had been killed in the past.
The work was completed on the generator rotor, it was reinstalled and brought back on-line. Some time later, in the middle of the night, the engineer friend sat up in bed having suddenly realized the error the time traveler had made in his return calculations. As he reached for the phone to call for the shutdown of the generator, he heard the explosion at the power plant several miles away.
The time traveler had returned to his point of departure inside the shell of the generator. His mass of 180 pounds had been added, off center, to the rapidly spinning rotor. The resultant imbalance tore apart the generator, shorting the circuits, etc...

I saw a TV movie years ago (don’t remember the title) about an Elvis impersonator who travels back in time and meets Elvis just before he made his first recording at Sun Records. The two end up getting into a fight, and he accidentally kills Elvis. Realizing what he’s done, the impersonator tells himself that there cannot be a world without Elvis Presley in it, so he decides to take his place, does the recording session at Sun, and lives the rest of his life as the person that everybody thinks was the real Elvis Presley.

Absolutely amazing video:

Exactly!
I've brought this up many times in time-travel discussions. The Earth, she rotates. She also travels around the sun. The solar system travels around the galaxy's rotation. The several galaxies in our local group have relative motion relative to each other. The universe itself appears to be expanding. Taken together the cumulative Delta-V is significant. If you want to go back to see the dinosaurs, you're going to need not only a time machine, but a spaceship with an FTL drive, and damn good records of the relative positions of not only our sun within it's galaxy, but the motions of the Local Group as well.
The computation required just to find your way home would be ... astronomical.
All that said, I still really like time travel stories, as long as the writer remembers causality. Breaking causality pisses me off.
