It rolls up into the other side of the cassette. Just flip it over.
I thought the sentense was going to lead to something like “It rolls up into the other 8 inaccessibly tiny dimensions of our space.”
I love your oldschool explanation though!
It turns out the solution to quantum string theory is a double-sided tape.
Tell him about the day that music died
Great song 👌👌👌
It turns into memories and heat.
I’m not a scientist by a long shot, but my understanding is that sound if indeed a wave, carried by a medium (air, water, etc). Upon hitting your eardrum, this wave is converted by your eardrum and your auditory nerve into signals your brain decodes. The remainder of the wave continues though, until it runs out of medium, hits an obstacle (basically another medium) or dissipates. Again, just my layman’s understanding!
False, it gets stuck in my head, to be played over and over until the next song gets stuck in my head.
Don’t forget the inverse square law. Even without a change in medium or any obstacles, the strength of the signal decrease over distance until it is undetectable.
This is also why there are no extraterrestrial civilizations hearing any radio broadcasts from Earth. Our transmitters are so weak that any signals we send out fade into the CMB before they get any real distance.
You area conflating auditory waves with radio waves.
These are very much not the same thing. Sound waves require a medium while radio waves do not.
Radio waves travel vast distances through space while sound doesn’t travel at all.
Space is a medium, as exemplified by the fact that light curves around massive objects, because the space is curved.
Space isn’t a medium because mediums have privileged frames of reference.
You’re talking about spacetime which is a field, not a medium.
So you’re saying that light can travel through not-space?
Light is also not “stuff” - it’s electromagnetic radiation. It’s by the unprivileged intertial frame of reference that we define the speed of light. Light’s speed is the speed at which it travels unimpeded through the spacetime “field”. Additionally light does not accelerate or change speed in any way while traveling in that frame.
Unless you’re asking if light travels through things that are not the field known as the spacetime continuum in which case yes: light travels (and changes speed) through all sorts of materials. Like glass.
So Lrrr and Ndnd warching Single Female Lawyer 1000 years in the future is a lie?
Unless they have an extensive network of wormhole repeateds
They’ve probably just got a spy satellite around earth that transmits back. Or maybe an extremely directional antenna / receiver dish would work, since they’re focused on Earth specifically.
They would not have been able to watch it from an original OTA broadcast, no.
If we had FTL I’d be a radio archaeologist, flying out to various distances to attempt to capture lost episodes of old TV shows like Doctor Who
If they didn’t fade with distance,
So for now we are still quiet in the dark forest.
A little bit reflexts off your eardrumm too!
It gets stuck in my head for 3 to 4 days until something newer comes along and pushes it out.
Everyone knows this duh!
Into your heart!
Groove is stored in the heart
the music goes back again to be later re streamed to other people that might need it
In your ears
It goes out into the world, to be merged alongside all of the other sounds, until it can be recycled as “new” music and you can enjoy it again:-).
It goes on until it doesn’t? Seems like there’s a pseudo-scientific philosophical argument that it continues on forever at some quantum level?
There’s a physics argument that information can’t be destroyed, so in terms of causality it has an effect (see butterfly effect for reference) but because of various physical thresholds like the planck length, general limits on measurement precision (uncertainty principle, resolution limits, detection limits), chaos theory, etc, at one point it becomes indistinguishable noise.
“Ultimately it increases entropy… let me tell you about the heat death of the universe…”
“No, Mom! I’m still afraid of the False Vacuum monster laying underneath my ground state!”
If those were likely to hapoen during our lifetime then they would have already. Now prion disease…
Good night!
Scare me with prion disease?

The pony. He comes.
I was curious, what that looks like when he does come
What the fuck am I looking at
The pot of gold at the end of the rainbow in latent space for the phrase you just said. Er if that was you that I replied to.
So scientists are not entirely certain about the heat death of the universe. The heat death is the most reasonable prediction given what we know but there could be a force acting across the universe that may very slowly reverse the expansion of the universe that we have yet to discover and cause a big crunch over a ridiculously large amount of time. The fact is predictions that far in the future aren’t really very useful.
Does quantum foam occasionally spawn a new big bang
I don’t know enough to answer that, sorry.
I asked chatgpt and the answer is inconclusive
Does quantum foam occasionally spawn a new big bang ?
The idea of “quantum foam” occasionally spawning a new Big Bang is an intriguing concept, but it belongs more to speculative physics than established science, at least with our current understanding of cosmology. Quantum Foam:
Quantum foam (or spacetime foam) refers to a concept derived from quantum mechanics and general relativity. It was first proposed by physicist John Wheeler in the 1950s. The basic idea is that on extremely small scales, close to the Planck length (~1.6 × 10⁻³⁵ meters), spacetime is not smooth but fluctuates wildly due to quantum uncertainty. This is because, in quantum theory, at these incredibly small scales, particles and even spacetime itself undergo constant, random fluctuations, resulting in a “foamy” structure. Quantum Foam and Big Bangs:
The speculation that quantum foam might give rise to new universes or Big Bang-like events is tied to broader ideas in theoretical physics, including concepts like quantum cosmology, eternal inflation, and multiverse theories.
Quantum Fluctuations and Universe Creation: In some models of the universe, it is proposed that quantum fluctuations could give rise to entire universes. This is somewhat similar to how quantum fluctuations in energy can spontaneously create particles for brief moments (due to the Heisenberg uncertainty principle). Some cosmologists have extended this thinking, suggesting that a fluctuation in the quantum foam could create a new region of spacetime that expands and becomes a new universe—a new Big Bang, in essence. This is related to the idea of the multiverse, where new universes are constantly being generated through different mechanisms, including quantum fluctuations.
Eternal Inflation: Another theory that links the idea of new Big Bangs with quantum processes is the theory of eternal inflation, which proposes that our universe is just one “bubble” in a larger multiverse. In this model, the universe experiences a rapid expansion (inflation) in its early stages, and in some regions, this inflation never stops. Small regions of spacetime can “bubble off” from this eternally inflating space and form new universes with their own Big Bang events.
Cyclic or Bounce Models: There are also cyclic models of the universe (such as the ekpyrotic universe or conformal cyclic cosmology) where a universe goes through repeated cycles of expansion and contraction. In these models, the quantum foam might play a role in transitioning from one cycle to the next, though these are still speculative ideas.
Does Quantum Foam Directly Spawn Big Bangs?
Currently, the connection between quantum foam and the creation of new Big Bangs remains speculative and unproven. Our understanding of quantum gravity—the theory that would fully unify quantum mechanics and general relativity—is still incomplete. Many of the ideas related to the quantum foam, multiverses, or eternal inflation remain theoretical and lack direct empirical evidence.
While quantum foam might offer an intriguing arena for considering the birth of new universes, there is no definitive evidence that quantum foam occasionally spawns new Big Bangs, at least according to current mainstream physics. In Summary:
Quantum foam describes the hypothetical, fluctuating nature of spacetime on extremely small scales. Some speculative theories in physics suggest that quantum foam or related processes could, in principle, give rise to new universes (possibly via quantum fluctuations or other mechanisms). These ideas are part of multiverse theories or eternal inflation models but remain speculative and are not established as fact. The idea of quantum foam spawning Big Bangs is fascinating but is still in the realm of theoretical and speculative physics.
Scientific advancement, especially in quantum gravity and cosmology, might eventually give us more insights into whether such processes could occur.
I read a SciFi book where there was a group in the world that does general science in the name of averting the heat death of the universe.
Ah yes, the ol’ “If a tree falls in the woods does it make a sound?” approach to preventing the death of the universe.
I don’t quite understand. Care to elaborate?
Oh, dear child, it goes to the same place where you will go when you inevitably die one day: into complete non-existence, save for an echo in others’ minds, and after a while not even that.
Sweet dreams!
To retire on a farm upstate, unless my mom lied to me 🤔
Heat. Everything ends up as heat.
Until the day that even heat dies.
Well, heat just spread over a larger area but it doesn’t get destroyer nor turn into any other form of energy.
But it doesn’t die per se.
If you consider particle excitement to be the definition of heat and subparticle fields to be different forms of energy then it does actually change, but that’s just semantics.
If all discernable heat is unobservable and unobtainable, then semantics don’t matter. Everything still dies. I’d include “heat” in that mix, but that’s waxing philosophical
Well not all sound.
But yes 99.99%
So where do smells go?
they get trapped in your nose hairs, this is why old people have really stinky noses.
Really? How can you smell?
well i’m not very old yet so i can smell many different ways depending on how recently i showered and whether i put on perfume
Just open a window. I’m sure they noticed, but they’ll be cool about it.
Oh, and while the king was looking down
The jester stole his thorny crown
The courtroom was adjourned
No verdict was returned
And while Lenin read a book on Marx
A quartet practiced in the park
And we sang dirges in the dark
The day the music died
