Getting hit by a car in Manchester England might do, painful as it sounds.

At least the Brit version of Life On Mars was original.

No. Niven’s Law. In any universe where time travel is possible and invented, the users of time travel will alter the universe’s history until they create a universe where time travel is never invented.

That’s the universe we live in now. Time travel will never be invented.

“The moon circles the earth”

Nope. The moon and earth orbit about their common center of mass.

The reason time travel is impossible is that we are never in one spot with in the universe, we are in constant motion.

You’re close. Time travel is impossible because time doesn’t “physically” exist. Time is simply a measurement. What does it measure? Motion. And, yes, motion exists.

What we’re doing is a one-way trip to our Final Destination. We can’t do time tourism.

Exactly. If it were possible to time travel to the past, there is no way the RATS would have let Donald Trump, or Ronald Reagan become President.

“Time is simply a measurement. What does it measure? Motion. And, yes, motion exists.”

Hmm. That is interesting but motion compared to what?

Einstein stated that any reference frame of view is as good as any other. My reference frame is centered on me with the rest of the universe in motion around me. I am sitting on my couch and the only thing in the universe not at motion but somehow time seem to move forward for me.

I think acceleration, not motion or velocity, changes our rate of moving through time compared to others with different acceleration.

I can accept “close” since I am a High School drop out (quit in 11th grade in 1964 to join the Army where I got to travel and see the world, at least Vietnam). LOL :-)

We don’t move through time. We move. Time measures the velocity (acceleration) so we can make sense of it (and utilize it).

I filled my car with thyme and drove in reverse.

Does that count?

Shatner’s UnXplained(sp) has a episode on his series on history channel that I saw a few nights ago, called The Time Travelers. The show talked about the US Navy experiment involving an incident with a destroyer (US Eldredge) and it’s involvement in a time travel attempt (The Philadelphia Experiment). It is worth watching if you’re interested in that type of thing.

Of course if Time Travel were possible, not only would I make sure No Hitler, but No Karl Marx, and No Mohammed.

License plate = ID. The DMC knows that she's:

OUTATIME:

Ancient Greek Orpheus with a violin (invented in the 16th century*)
rather than a lyre. A 17th-century painting by Cesare Gennari

https://en.wikipedia.org/wiki/Anachronism

In Greek mythology, Orpheus (/ˈɔːrfiːəs, ˈɔːrfjuːs/; Ancient Greek: Ὀρφεύς, classical pronunciation: [or.pʰeú̯s]) was a Thracian bard, legendary musician and prophet. He was also a renowned poet and, according to the legend, travelled with Jason and the Argonauts in search of the Golden Fleece, and even descended into the underworld of Hades, to recover his lost wife Eurydice.[1]

>>>

Greeks of the Classical age venerated Orpheus as the greatest of all poets and musicians; it was said that while Hermes had invented the lyre, Orpheus perfected it. Poets such as Simonides of Ceos said that Orpheus's music and singing could charm the birds, fish and wild beasts, coax the trees and rocks into dance,[15] and divert the course of rivers.

https://en.wikipedia.org/wiki/Orpheus

Ancient Greek Orpheus with a violin (invented in the 16th century) rather than a lyre.

YET,

lyre = kinnor = violin

Kinnor (Hebrew: כִּנּוֹר‎ kīnnōr) is an ancient Israelite musical instrument in the yoke lutes family, the first one to be mentioned in the Hebrew Bible.

Its exact identification is unclear, but in the modern day it is generally translated as "harp" or "lyre",[1]:440 and associated with a type of lyre depicted in Israelite imagery, particularly the Bar Kokhba coins.[1]:440 It has been referred to as the "national instrument" of the Jewish people,[2] and modern luthiers have created reproduction lyres of the kinnor based on this imagery.

The word has subsequently come to mean violin in Modern Hebrew.

the "national instrument" of the Jewish people...

In modern Hebrew a kinnor is a violin or fiddle and a nevel is a harp or lyre.

In the Bible they are found together.

In the Bible, "kinnor" is spelled without the yud.

As such, kinnor [כנור] + nevel [נבל]

= 358 = Messiah [משיח].

There's a Stradivarius for that, a kinnor.

*invented in the 16th century -- odd how that's also the claim for the midrash about little Serach playing her harp (kinnor) for her grandfather Jacob, to inform him that Joseph was still alive and living in Mitzraim.

Sefer HaYashar (midrash)

Serach bat Asher - The Transmitter of Secrets

(It's for a good cause.)

If time travel is possible, then either the human race dies out or we have a police state in the future, as we never see time travelers from our future.

Or perhaps we never solve the puzzle.

Somebody is sure to say, well perhaps the future travelers are able to disguise their presence. But you have to believe that if a lot are doing that, at least once or twice they would fail or forget.

Or perhaps the years up to 2024 are off limits, but some future year is not off limits and suddenly — time travelers up to your eyeballs.

Time travel:

I should have added that section (Berakhot 3b 20-29) about how David knew it was midnight. There was a debate over what time was what.

Source verses:

Pslam 119.62. At midnight I will rise to give thanks to you because of your righteous judgments:
Psalm 119.147. I rise before dawn, and I cry out; my hope is in your word:

Torah [תורה] = conspiracy [קונספירציה]

= 611 (119 upside-down)

Ergo, he was up with the Torah before dawn (aurora = "dawn").

HAARP: High-frequency Active Auroral Research Program
Alaska: "Land of the Midnight Sun" [ ארץ שמש החצות] = 1440

= 60 min x 24 hrs

Which is to say, when *isn't* it midnight in David's house. Or dawn, for that matter.

(It's for a good cause.)

To the chief Musician, according to Ayeleth HaShahar, a Psalm of David..
