I’m glad time travel isn’t real

In a different time-line

In that case it’s meaningless to travel back in time in the first place. Unless you just wanna get to vibe in a 70’s disco just for fun or something like that.

We had tv shows that had different earths.  Something in the past changed what the course of history.

They did not make the change themselves, just what the charges became.

Sliders

A boy genius and his comrades travel to different parallel universes, trying to find their way back home.

Quantum Leap

During a government experiment into time travel, a scientist finds himself trapped in the past, “leaping” into the bodies of different people on a regular basis and sorting out their problems whilst trying to get back home to his own time.

Revisit the past.  Relive the past.

Of course, going back in time, has alot of other hazards.

How far back can you travel and still be able to communicate (language and dialects change over time).

So going back in time 500 years to when “old english” was spoken, the odds you could talk to some and understand them is small.

Then there is the diseases.  Would the time traveler be immune to the diseases of that era?  Would people of that era have immunity to any disease a time traveler might bring with them?

That is, if we can physically travel back in time.

Would it be like Star Trek or Terminator?  With full technology or just organic material?

But if we could only observe the past, would that be enough?

Instead of telescopes looking to objects far far away, and a different point in time (billions of years in the past), if we can view earth’s past, should we?

We can finally explain how the pyramids were made, by seeing them being made (but not being able to interfere).

We can finally see what a full colored Sphinx looked like, and further back if it was a lion before being re-carved into the sphinx we now know of.

We can finally see if the Sahara at one time used to be a lush forest.

We can finally see the seven wonders of the ancient world.

We can finally see what exactly killed the dinosaurs.

We can finally see what happened between the five ice ages of earth.

We can finally see how stone hedge was made, as well as easter island’s statues.

There is so much we can learn by just observing the past.

There’s a theory in quantum physics that all outcomes exist until you observe the environment – and because we are stuck in one particular timeline we are confined to only being able to witness one outcome, so one of the more likely outcomes is picked for us to observe at random at the point of observation. If true then this means that the Pyramids were constructed in every possible way (made by God, aliens, humans, other species, they spontaneously formed…) until you see how they were constructed and then it is fixed to only that way – like Schrodinger’s Cat being dead and alive at the same time until your observation determine the outcome for you. This also means that if you and I each separately observed how the pyramids were built – as long as you and I never interact with each other – we could each see different ways that they were built. So for all intents and purposes we will exist in separate timelines. It’s like a game that’s procedurally generated for each player.

Bad idea just like preventing slavery, it would basically erradicate mankind as we know it, you would never been born, no afro american would ever been born, who knows what else.

That’s what the multiverse is for, our time-line/universe stays intact while we mess up contless other realities to see what happens 🤪
