I asked myself, "what did I have for breakfast tomorrow morning", my answer, " I don't know, haven't ate breakfast tomorrow yet", so, how can forward time travel be at all possible if future events have not happened yet?
... this is a common SF fudge, that is correct.Then you could go back in time, kill your grandfather, and continue to exist because in the new time line you created by going into the past you never would have existed in the future, and therefore there is no paradox...
Yes, but the premise is still the same, how can you travel to an event that has not happened yet in any timeline? Backward time travel is only possible to the point at which the machine was built, so we build a backward time travel unit, launch it to go to the exoplanet of our choice, say it takes 10,000 years to get there, when it does it turns itself on and connects to the second unit we built in our time. Just a thought passing through the vacuum of space in my mind.Simon Bridge said:... this is a common SF fudge, that is correct.
OP question remains confused because, to specify a date/time uniquiely requires specifying the timeline also. This was not done so the question is poorly posed.
"What I had for breakfast tomorrow" referrs to tomorrows date in the other timeline.
This is something you'd have to account for in your story.Madpoet626 said:Yes, but the premise is still the same, how can you travel to an event that has not happened yet in any timeline?

You often see this statement in sci fic but I'm not aware of any actual such limitation on an actual magical device that could travel backwards in time, I think it's just another sci fic statement based in making your own rules for the magic (after all, you can't use physics rules so you might as well make up your own).Madpoet626 said:...

This topic is not appropriate here. If you wish to say it's for writing, then you need to follow the rules for that forum and post in that forum.

Time travel is the concept of moving between different points in time in a manner analogous to moving between different points in space. It has been a popular topic in science fiction and has been studied by scientists and philosophers.
There is currently no scientific evidence that time travel is possible. While there are theories that suggest it may be possible, such as wormholes and time dilation, these are still theoretical and have not been proven.
Some unanswered questions about time travel include: Is time travel restricted to the past or can it also occur in the future? Can we change the past if we travel back in time? What are the potential consequences of time travel?
Many time travel theories propose that changing the past could create a paradox, such as the grandfather paradox where a person travels back in time and kills their own grandfather, thus preventing their own existence. However, there is no scientific evidence to support these theories.
If time travel were to become a reality, it would greatly impact our understanding of the universe and the laws of physics. It could potentially challenge the concept of cause and effect, as well as the idea of a linear timeline. It could also open up new possibilities for space exploration and understanding the origins of the universe.
