#SciFi fans know that (#retrograde) #Time #Travel breaks basic #logic. If #interdimensional #transport is to be pursued, then logic may have to be violated.

Gavassino's new #study doesn't so much remove the #GrandfatherParadox, as it suggests how higher #physics could provide a workaround.

When reading maths or physics texts, I often struggle with ambiguities none of my peers seem to be seeing. Here's an example about time travelling.

People say, if you could move faster than light, then you'd move backwards in time.

To me, this is ambiguous, but most just go on and say that that would cause problems with causality, and destroy the universe.

What? Let me be more explicit:

If a spaceship moves near the speed of light, time _on it_ would move slower, and if it, after a reasonably long journey, would return to earth, its clocks would say, "we've been underway for a few months". But they would find themselves on earth where a decade had passed.

So if that spaceship could travel #fasterThanLight, its crew would not have started the journey yet by a few months, but the clocks on earth would still have measured a decade!

See what I mean? I run into problems like these all the time, still struggling, while people are already discussing the #GrandfatherParadox.

CW: (SPOILER) Quantum Leap Season 01 Finale reaction

#QuantumLeap s01e18 was the best episode and very satisfying season finale.

Before anything, #SPOILER!

---

Top 4 things I love the best:
1. Ben using quantum entanglement to explain their “fate”.

Wow. I used that explanation with my 15-year girlfriend. But the thread of fate, I mean, our entanglement was disentangled in late 2020. LOL.

2. Addison's reaction to Ben's quantum entanglement reaction.

Was so perfect and fitting. The moment I heard Ben used it, I had the exact same reaction as Addison. That's exactly how you react to a quantum entanglement cheesy pick-up line. ROFL!

3. The use of “quantum bubble” / “time bubble”.

I reacted so lively when I heard it, because, as a time travel fan and writer that phrase is rarely used as a label and as an explanation. I independently came up with it in the mid-90s as a way to: (1) keep a single timeline; and (2) avoid a grandfather paradox. BUT, I am not the only one who came up with it. In fact, it has been around far earlier than the mid-90s. It just so happen the phrase and the word ‘bubble’ are rarely used. Yet the idea has been used here and there for the exact same purposes: keep a single timeline; and avoid a grandfather paradox.

4. The shortest and simplest explanation of a quantum/time bubble.

Yep. It is the shortest and simplest explanation I've ever heard. “Time inside the bubble is in flux.” Because, that's exactly what's happening inside a quantum/time bubble. There is no past, present, or future, there is only “now”. Anything and everything are constantly being created and destroyed.

Kudos QL Season 1 team! I can't wait for Season 2!

@dredmorbius solution to the #GrandfatherParadox: stick him in a box with a flask of potion and a radioactive source and make sure no-one can ever observe him.
Now he can be both dead and alive to solve the paradox. ;)

Well, I guess you also have to stick your grandma in there too...

Huh, perhaps the exposure to the radioactive source is the source of John Oldman's perfect regenerative powers...

MFW I realise that scene in The Man from Earth is an inversion of the Grandfather Paradox...
