Your best bet is to snoop state property auction sites and bid on 'scientific equipment' auctioned off by universities. Sometimes you can find electron microscopes in those lots. Whether they work or not is another matter entirely.

>the size of a black hole (some bigger than out entire solar system) is literally just the empty space beyond the event horizon

For some weird reason i always assumed the mass of a black hole is also defined by some sort of material, but it all is focused in the singularity at the center. So every black hole in theory has the same "size", the singularity. What differs is how far the event horizon stretches out?

The black hole is literally just empty space bounded by the event horizon with all the 9000 suns crammed in the singularity (a single point with no volume) in the center.

>The P versus NP problem is a major unsolved problem in theoretical computer science. Informally, it asks whether every problem whose solution can be quickly verified can also be quickly solved.
I don't understand why this is such a huge problem. Isn't the world full of things that obviously constitute solutions to certain optimization problems, merely by virtue of their existence? Things that attest to their own fitness with respect to reality's complex criteria, because they logically could not exist otherwise? For example, you hardly need any computations to determine that terrestrial life solves the problem of maintaining its own structural integrity over time under terrestrial conditions, meanwhile producing such a solution involves a monumental amount of computation no matter what.
>>
>>16840504
Terrestrial life need not to be optimal in any way, only to be good enough. There are many aspects of the human anatomy that is deeply suboptimal but good enough to see a new generation brought up.
>>
>>16840615
>Terrestrial life need not to be optimal in any way
That's not the point. They represent acceptable solutions to a myriad nontrivial computational problems, which you can deduce immediately from their mere existence. I'm sure this doesn't count for whatever reason. I'm just waiting for some compsci fag to explain why not.

Earth is about 4.54 billion years old. The average day length has increased over time due to tidal friction. Early Earth rotated much faster, estimated 5 to 6 hours per day.

Using a rough integration of changing day length over geologic time:

~4.5 billion years ago: ~5 h days ~1,752 days per year

Today: 24 h days 365 days per year

Average across history: about 900–1000 days per year

Total rotations ≈ average days/year × years = (≈950) × (4.54 × 109) ≈ 4.3 × 1012 rotations.

>muh causes
>muh effects
>muh causality
You realize this is pure head canon, right? You can't demonstrate that something "makes" something else happen. You can't even explain what it means for anything to "cause" something. All you can do is observe a recurring sequence of events and fill the logical gaps between them with this mysterious "causality".

Consider how differently a murderer, a pathologist and a cellular biologist see a victim's cause of death: for one, the death was caused by stabbing the victim in the neck; for the other it was caused by a ruptured carotid artery; for the last, it was maybe some cascade of necrotic cellular processes. Each one will treat his "X causes Y" just-so story as an adequate and objective explanation, oblivious or indifferent to its failure to completely rule out other conceivable outcomes.

No matter how much you drill down, the logical gap between your causes and their supposed effects never goes away. You can never logically demonstrate that the effect follows from the cause the way a conclusion follows from a premise, except by way of extra premises that are circular or defeasible.

is not a retarded question at all
even if you take the much more lax condition of logical consistency, one thing following from another according to axioms of some logical system, well, most people don't do that with their minds most times
to say that something in the immediate environment of the thinker "caused" a thought is also kinda silly
say I hear Dworak played by Art Tatum and I am reminded of my grandparents - does this happen "because" my grandparents existed? "because" of Art Tatum? "because" of Youtube? "because" of something unrelated I did last evening which affects my mental state now? coincidence? happenstance? algorithm?
then you have the really weighty questions - the ones about the world outside of our minds
what "causes" pi? how about the fine structure constant?

Quantum immortality says you can never die.

String theory says that there are extra dimensions.

Standard quantum immortality is a dreadful thing, but if these extra dimensions of string theory are relevant to life in any way, it is possible that a dying person could pass into another brane and life happily rather than suffering the terrible fate that standard quantum immortality proposes.

The math works out, it's just untestable.

Image for a moment that the gravity magic of Lord of the Rings or Elden Ring is real.

You can create a bubble of a few cubic meter inside of which gravity instantly ticks over to 4G.

What happens to air in this sort of a situation? Is there cavitation at the top of the boundary? Does the system pressurize? Does it turn into a dyson bladeless fan? Does it catapult you up like a rocket? Does nothing happen?

Keep in mind this is magic, no curvature, its a step transfer from 1G to 4g, there is no slope.
>>
>>16840138
>Is there cavitation at the top of the boundary?
No
Atmosphere at earth gravity is anywhere from 10km to 100km deep depending on your use case, double gravity roughly speaking packs the same air in half the space so even at 4x that same column would extend at least 2.5km up. For a closed bubble of 2 meters in height the top would "feel" the same as if you climbed up to 8 meters in real life so you would not feel a thing from that. You could certainly measure the effect but you wouldn't be able to intuit the pressure difference.
>Does the system pressurize? Does it turn into a dyson bladeless fan?
If the magic bubble is permeable to air then ye it would turn into a fan of sorts. Air would drop into it from the top and then exit from the bottom. Small bubble like that would not accelerate much air nor to great speeds but I presume you could feel it moving.
>Does it catapult you up like a rocket? Does nothing happen?
Nothing would happen to you except of course being slammed to the floor by the 4 gravities which is what the wizard was aiming for, he wins you lose.

Stupid question, but light is "electromagnetic radiation". But what part of light is "electromagnetic"? I heard it's supposed to be fluctuations of the E and B fields but I don't really understand what that's supposed to mean or if that's even right. Does it interact w/ electric and magnetic fields? If I have a really strong current or electric field, can I use it to affect the trajectory of light? I know that electromagnetic interactions are supposed to be mediated by photons but what exactly does that mean?

>This is the part that confuses me. Where are these photons when an iron sticks to a magnet?
These are not actually photons. In a calculation, they just show up as integrals. You can calculate the forces just doing the integrals, and not giving them silly names.
Feymann tried to create a human-readable narrative of what was going on, and created an equivalency between the abstract math and his drawings of diagrams with real and virtual particles, all of which are otherwise dry integrals with no name.
Strictly speaking, virtual photons are a narrative device by Feynman, the source is just a scattering calculation that requires solving the schrodinger equation for interactions.
