Once time travel is invented who knows when it was invented?

 

 

I grew up on science fiction.  I've always enjoyed discussions about the nature of time travel.

 

Now, we have the new physics, which has a mathematical model of three dimensions of space -- and a dimension of time.  Interesting stuff.

 

Using this model, it seems to me that if the past is fixed and unchanging -- I hope -- then maybe the future is also fixed and unchanging.  It seems contrary to the uncertainty principle -- but who knows?

 

If the past can be changed, then reality is subject to revision.  This is where we get the fictional stories, about various time patrols -- to prevent tampering.

When the first time traveller tells me his story, I'll say, "What a load of crap!"

In a sense, we are all travelling forward in time.  It's reversing the arrow of time, that presents the problem in physics.

 

The alleged time travellers are already on Youtube.

What happens when you set your time machine for, say, 6 months into the future or past, you rematerialize, and the Earth is on the other side of the Sun?

It really depends on the physics involved.  If the Earth's gravitational field remains in constant contact with the machine; no problem at all.  You get pulled along.  Other wise, it is so much worse than that.

 

Earth does travel around the Sun.

 

The Sun travels around the center of the Milky Way Galaxy, as the Galaxy rotates.  We are near the rim.  But it's worse than that.

 

Our Galaxy is part of a Galactic Cluster.  We are in a larger rotation around that central point.  But it's worse than that.

 

The space between the Galactic Clusters, is expanding.

 

If the time machine loses contact with Earth's gravity -- within mere seconds, the traveler will be stranded in deep space.

This produces a freeze dried time traveler in orbit around the Sun.

Be careful if you encounter yourself in the past or future, do not make any physical contact, you will rip a hole in the universe.

I'm not sure how quickly the freeze dried effect would occur.

 

In zero air pressure, all the blood and other fluids would burst outward.  The eyes in particular.

 

If the fluids do freeze before they explode, they will still expand.  Think of water freezing in a crack in the sidewalk.  Now think of this happening to the entire vascular system.  The entire cellular system.

 

The air in the lungs would explode outward, even before the fluids.

 

It would be as bad a death, as anyone ever experienced.  

 

 

Don't be so sure that the traveler would remain in orbit around the Sun.  Again, the Sun is in rotation around the galactic center.  In half a year, the Sun would have moved thousands of miles.  We are still talking about being stranded in deep space.  Unless, the Earth's gravity pulls the traveler along.

 

 

This would be an effective means of preventing time paradox.  Time travel, combined with space travel, might make such paradox possible.

Maybe.  Maybe not.  Discoveries in quantum mechanics, suggest that location in space, is not what we thought it was.

 

One reason why I don't need the supernatural in my life -- the natural is strange enough.

When time traveling do not accidentally kill your mother a year before you are born.

If you're a man, don't have sex with her.  You could be your own father.  Like Jesus.

I reckon Jesus is his own grandfather too.

One of my favorite ideas about time travel; is that the past can't be changed.  If I travel back into the past -- I become part of the past.  Things unfold as they already have.

Multiverse theory.  You can change the past, but doing so creates an alternate timeline, and you can never return to your original timeline.  So if you altered history by killing Hitler as the popular fantasy often goes (not a good idea, for myriad reasons) you would return to a timeline where Goebbels became German Chancellor.  And if you killed your own parent, you'd end up in a timeline where someone else was your parent.

 

Sometimes I think we're living in an alternate timeline where Hillary Clinton rigged the Democratic primaries against the rightful president Bernie Sanders, to ensure that her longtime friend Donald Trump got into office and would never break up the big banks, thereby ensuring her continued flow of Wall St. wealth.

Yes.  It's a popular idea in fiction.  I have doubts about the physics behind that -- but maybe.
