In the Back to the Future movie, Marty’s young grandmother and teenage mother, living in 1955, took a look at Marty’s sleeveless vest and asked him if he was in the Coast Guard.

When Marty woke up in the bed at his grandparent’s house the next morning, Marty’s teenage mother back in 1955 saw his designed underwear and assumed his name was Calvin Klein.

All you need is a Delorean, and a flux capacitor.

You ain’t going nowhere without Mr. Fusion.

In “Back to the Future” didn’t they repeatedly ask McFly why he was wearing a lifejacket?

Time travel would be a navigation nightmare. The Earth rotates on its axis, but the axis also wobbles. The Earth orbits the sun, yet that orbit isn't circular. The sun orbits the center of our galaxy. The galaxy is moving along another path.

Let us go back to some point in time and materialize. What could go wrong?

For humans for the foreseeable future (and I am talking many millennia); time travel is impossible; forward or reverse.
Consider. We have no idea of where the boundary of our universe is; none. We only know what we have been able to observe but that in no way means there isn’t a vast expanse beyond what we can or cannot observe. Hence, we have no idea where we are in the universe as a whole. None because it all is expanding and we don’t know where the “edge” is which means we cannot possibly calculate where WE actually are as we hurdle through “space”.
Minus Andromeda, most everything else is flying away from us so we can’t get a good fix on where we are in the universe (because for all we know we are just part of a large chunk of what we “see” still moving about). That is the piece that stymies us and most likely always will. If we have no fix on where we are, how can we even travel two minutes into the past when we have no idea where the location of the Earth WAS at our time of departure two minutes in the future? Two minutes could put one of us on the other side of the Earth in a vacuum considering how fast our solar system is moving. 2 Seconds might put one of us in the Earth’s core.
Also consider the Earth’s rotation, the Earth’s position in the solar system; the Earth’s “wobble”, the solar system’s position in the galactic arm we inhabit; the dance our solar system does on the galactic plane moving above and below, The galactic arm as it spirals, etc..etc.. etc.
The math is staggering. To compute it alone will require mind boggling amounts of computational capacity let alone the energy it would probably take to pop a hole through a higher dimension to drop back (or forward) through space/time.

Just my $0.02

Thanks for the thread...I enjoy these types.

Ronald Reagan became President. Twice.

Knowing liberals as I do, this alone means that time travel is impossible.

f you owned a vacant lot, and hopped in your “DeLorean” and went 25 years into the future,

You would be in orbit around the Sun, not on the surface of Earth.

Actually, you'd be somewhere in interstellar space ...

Well that was fun, the only point I might dispute in all of those comments would be the difficulty of a time traveler “fitting in” — going forward, yes, because you don’t know what to expect, but going backwards, you do know and you could prep like an intelligence agent might do. Some might be more skilled than others at this. I would love to travel back to Mozart’s time, join his orchestra (possibly as a backup keyboard player) and amuse myself by playing Beethoven tunes not quite written yet (in 1788 let’s say).

People might not think I was that unusual except maybe for the constant washing of the hands that a modern person would no doubt be doing in that day and age. I could also amuse myself by writing letters such as this to the Times of London (if it existed then — I know there was no postal service so a personal visit might be needed) ... Sirs, I have developed a technique to foretell the weather and can inform you with considerable confidence that the winter forthcoming will be exceptionally cold. Your ob’t servant, Peter O’Donal — dated 15th November, 1794.

Time travel has not, does not, nor never will exist.

Why?

Because it doesnt exist now.

Yes.

This entire monstrosity is moving thru space at breakneck speed orbiting around the center of the Milky Way. If you travel back to a physical place in time, Main street in front of City Hall by the local movie theater aint gonna be where you think it was.

Very nice! It too easy to think our local theater stays put.
