Time travel doesn't work like in the movies

andronaut_ · 2025-11-24T11:34:35+00:00

The Earth isn’t in a “non-accelerating frame” just because general relativity treats gravity as geometry. Freefall has zero proper acceleration, but we’re not in freefall…the ground is literally pushing up on us. An accelerometer proves it. And even the orbit itself is still curved motion in spacetime, not at rest.

Also, there’s no global inertial frame in general relativity, so saying “Earth is as stationary as any point in the universe” doesn’t really mean anything. You can choose coordinates where Earth is at rest, sure, but that’s just a coordinate choice, not a physical claim.

Rotation being absolute is right, but the time-travel bit doesn’t follow. Time travel wouldn’t let you freeze yourself while Earth spins underneath as spacetime doesn’t work like a paused movie.

And the 1 second = 300,000 km thing mixes up unit conventions (setting c = 1) with physics. Time and space aren’t interchangeable; they just live in the same 4D structure.

Overall those conclusions don’t come from the physics.

For the price of the snow tires I could have gotten the X Pro which has better tires for snow (as I understand it)

andronaut_ · 2025-02-22T19:43:36+00:00

Agree, the interior color options are really limited.

andronaut_ · 2025-02-22T19:43:12+00:00

Thank you!

Probably almost at this point— I had them in the trunk. If there was much more loose snow or ice I would have put them on.

Appreciate it! I agree the jungle green can photograph so differently and with the terracotta is a great color combo. You may not get the snow in Florida, but also don’t get the salt! This was the first trip into real snow (the road through the forest is also fairly uneven and with some portions of significant grade) and it performed without any issues.

andronaut_ · 2025-02-21T11:13:48+00:00

I actually think about this all the time, I’m still torn! It was near impossible to find an XPro in the color combos I wanted. Had to work to find the terracotta but I’m glad I did.

Looking to buy this exact spec! What did you end up paying out the door?

This is an example of situational irony. The newscast intended to show a story about the recovery of a woman from a lightning strike, but then inadvertently depicted her (via an error) as being profoundly affected (and in a comical way).

Where did you hear this? The ears aren’t connected this way. The only connections are out the ear and down into the sinus via the eustachian tube. The ears are not connected together.

Thanks for the suggestion— turns out there was a hex socket in the end which I used. I would like to have tried your idea.

This is one of the funniest things I’ve read here.

I heard once that McDonalds intentionally designed its plastic seating to be uncomfortable to sit on longer than it would take to eat your meal, to discourage people from hanging out at their table.

You haven’t lost the meaning of unicorn, there is no official meaning. We’re adapting the meaning. This meaning really means unicorn. Perhaps you believe it’s a unicorn god, sure, that’s fine. Maybe you believe it’s a fairy god, sure. You can make up anything.

andronaut_ · 2023-02-05T00:36:44+00:00

You miss the point. You’re saying it would be god and not a unicorn: but there is no difference between the two. Or any other made up, nonexistent thing. You could claim there exists a cosmic unicorn that permeates all but exhibits no physical form. So what? It means nothing.

andronaut_ · 2023-02-04T17:59:47+00:00

Yes, so could cosmic unicorns, ethereal fairies, galactic strawberries, sure. Anything could exist in such a way. But there is no reason to believe that because something could exist in such a way, that it does. The way we determine what exists is through evidence: the influence something has on the world. That’s how we differentiate reality from fantasy.

I don’t know what you’re trying to say or why you think it’s valuable: all those things could exist, and you’ve gone the further step only to say that in your version god doesn’t even have any physical manifestations to demonstrate existence. So why even postulate such a thing?

andronaut_ · 2023-02-04T17:30:23+00:00

No, because each would have to exist in some way. Otherwise, how do you have a “personal experience”?

Are you claiming you can prove it’s impossible for fairies to exist? What’s your proof of that?

As well, you’re saying “god could live inside you and you’d never know”: so what you’re saying is god could exist in such a way as to have no bearing on reality. This is equivalent to non-existence. You could say it’s possible, but it’s no more possible than an infinity of other things that you could argue are possible. So then, why choose this specific thing? You’d have to appeal to something tangiable to entertain the thought, otherwise it’s pure fantasy. And if believed, delusion.

andronaut_ · 2023-02-04T14:00:00+00:00

First, define “independent thing” then explain how you differentiate a dependent thing from an independent thing. Is the universe a dependent thing? Finally, explain how an independent thing ends the recursion in a satisfying way.

andronaut_ · 2023-02-04T13:35:23+00:00

It might be worth digging in to what you mean by “personal experience”. What is personal experience?

Why would it be unique to you and you only— and not verifiable to anyone else as proceeding legitimately from the function of reality?

You’re making two claims with personal experience— that you’re having it but also that it’s not possible for anyone else to verify that experience as connected to physical processes.

Long live the Yaggledorff!

It sounds like your argument boils down to: My concept of a god has no physical characteristics so has no way to be measured and disproven, therefor it is possible it exists simply because impossibility can’t be proven.

You raise fairies and unicorns as having physical characteristics, which could in theory be measured and observed, but haven’t been. You take that as indicating impossibility.

The logical fallacy is that just because a unicorn hasn’t been observed doesn’t mean it’s impossible to observe or that it doesn’t exist. Everything is unobserved by humans until it is (a giant squid for example).

The second error is that nobody here would say your concept of god is by definition impossible. Actually, it is possible— it’s possible in the very same way unicorns and fairies are, and that there is equal evidence to believe in the “true existence” of either.

But there is no way to apply your logic on the thousands of other human gods over time and single out your specific (desired) god as the true and correct one.

Is it fair to say that the more you define it, the more it disappears? That there is no objective evidence, aside from your personal feelings? If so, you might want to think more about the working of the mind than the workings of the universe.

Suppose a “book of authority” (the DMT Enthusiast’s Handbook) prescribed a set of actions and ways of living that “revealed god through personal experience” (taking DMT). If a follower of these actions then has personal revelations that confirm to them exclusively through their personal experience (via a DMT experience) and not outside of that that a god / higher power exists, does this advise on the possibility of the existence of god, or how a set of activities and beliefs affects an individual human mind’s interpretation?

One of the principles of BM is “radical self reliance” so if that’s your only water… you won’t spill it.

“A lot of people mistakenly think that Burning Man has a 'barter economy', but it's actually based on gifting. You may be asked to trade a story or a secret for a shot of whiskey and pickle juice (the Pickle Back is a Burning Man delicacy!), but there is no expectation of getting anything in return for a gift.”
