Just because some things are ambiguous doesn’t mean all things are ambiguous

Well, parts of interstellar are accurate. :)

Wait, you’re telling me it’s not scientifically accurate to say that love is the one thing we’re capable of perceiving that transcends the dimensions of time and space? /s

You may think this breaks the symmetry I brought up earlier, and it does, but that symmetry breaking occurs when the rocket accelerates a whole bunch turning around and heading back home.

Ah, okay that answers my question then. It’s the acceleration and deceleration that changes things. Thanks for bearing with me so far and answering all my questions!

They also provide a protective layer that helps prevent the cereal from getting crushed. Potato chips do the same thing by adding a lot of air to the bag

I think the word ‘unironically’ has started to fill the void left behind after the word ‘literally’ was changed to mean ‘figuratively’

Where I’m from we have a major river flowing through the heart of our city and we turn it into a frozen ice rink every Winter. Works great until the windchill hits the minus forties or fifties, then it’s time to stay inside with a nice cup of hot tea

That’s interesting, thanks for explaining.

This means outcomes need to be symmetric.

I guess I’m just confused as to how you can have situations where someone ages faster than another due to time dilation. That doesn’t seem to be a symmetrical outcome. Like this scene in Interstellar (which, as I understand it, is scientifically accurate). In this scene Matthew McConaughey goes away for 3 hours and finds that, due to time dilation, his kids have aged 23 years. There doesn’t seem to be a symmetry here. Because Matthew McConaughey aged slower than his children, it would be weird if, from his point of view, his kid’s clocks were ticking slower than his (his kids can’t also think that he has aged 23 years in 3 hours). So how do you resolve this lack of symmetry with the requirement that outcomes need to be symmetrical from both these reference frames?

Granted, in this scene Matthew McConaughey ages due to gravitational time dilation. Is that somehow make things different? Would a similar scenario not be possible with time dilation solely caused by travelling at very fast speeds?

(Please let me know if I’m not making sense with these questions, and I’ll try to reword them)

Jesus Christ man this is schizo shit. Calm down. This post has 265 comments. I was inundated with stuff in my inbox. I wasn’t able to keep track of every link anyone ever sent me, and I couldn’t read every response immediately either

Okay, so I guess a takeaway here is that each person only observes relativistic effects in the other conversation participant, but not in themselves.

I’m still about confused though with how this would work with time dilation. Like, imagine a scenario where I go in a spaceship and approach lightspeed for a while and then come back (for me, subjectively) a short while later, only to find that I had grandkids that were all senior citizens. It makes sense in that scenario that, if I were to view Earth, time would seem to be moving slowly over there. But I don’t understand why, if people on Earth were observing me, they would also observe my time to be going very slowly. Intuitively it would seem that they should observe my time as moving very fast, since relative to them it is

How cold does it get there?

Do you think the people on lemmy repeating these claims are largely just falling victim for it, or are a lot of these accounts run by disinfo influncers?

How’s life in New Zealand?

Meshtastic does seem very cool

That’s interesting. How would this work with length contraction? Would both sides view the other participant in the conversation to be experiencing length contraction?

In context it doesn’t seem like much of a warning. “Shots fired” is an idiom, freedictionary.com defines it as follows:

a humorous phrase used to acknowledge that someone has said or done something insulting or argumentative.

When you look at the quote in context that seems to be how she is using the term

What can I, as a regular guy, do to help make this happen?

I remember reading something Darwin wrote, in the Descent of Man I think, and he said the brain of an ant is far more fascinating than the brain of a human. With human, you can at least kind of understand how you can fit all that intelligence in a brain of that size. But with an ant, it’s way more intelligent than you’d expect given its brain size, so an ant brain is more interesting. Something similar could be said about bees

Although, if it was real, then the Secret Service really fell down on the job.

I heard they caught the guy at the first security checkpoint, or is that not true

The exact opposite…

I see

The lemmy administrators did recently get into a spat with someone who seems…motivated and unique.

What happened here?

Was it a bad idea for there to be mass defederation of the MAGA instance? Not asking because I support that viewpoint (like most Canadians I am very anti-MAGA) but I wonder if it would have reduced the echo-chamber effects you’re describing
