Only from the cube's frame of reference. The problem here is that space itself is being manipulated

>>729663892
Well we understand it now not as an attraction towards one another, but as a straight path through a spacetime that is curved by a massive object.

I'm sure you've seen the analogy of the bowling ball on a trampoline kinda shit? It's basically like that except time curves and warps as well. And what you see depends on your position in a coordinate system.

The equation above is actually a set of ten equations called the Einstein Field Equations. They relate the curvature of spacetime to the mass-energy content that is causing the curvature.

>>729664099
agreed, from the perspective of the portal the cube is comming in with a high velocity.

>>729662381
why is the behaviour of matter affected by observation? ie. self-interference of particles/waves.

>>729664745
It seems like, for some reason, the presence of mass and energy geometrically warps spacetime. This means that anything, including light rays, that pass close to the warped spacetime will be deflected. In relativity, it's important to note that in a given frame of reference, the universe will not look any different, no matter how fast you are going. I.e. if you performed an experiment going at 0.99c, it would look the same as if you were going at a regular speed. Also, a related idea is that no matter how curved the spacetime is, on a small enough scale, it will always look flat.

Sorry for ranting, I'm studying for relativity exam just now.

At time t2 measure the momentum of this particle to an arbitrary accuracy

Do this such that (t2-t1)*c < hbar/Delta p = delta x

It's got a fundamental effect on the nature of matter.. this shit should concern all physicists. Like, how do they ensure that the particle flying down the dildo collider stays a particle at the moment of impact?? Or how do they know it was in fact a particle when it hit the other atom?

>>729665746
I don't think so, and I'm not sure why you would need one. I think the uncertainty principle on its own can describe relativistic particles.

>>729665802
Confusing as fuck, but exciting as fuck. Optimising the shit out of everything sounds like a good deal tbh.

Apparently tunneling happens instantly and the particle just appears on the other side of the barrier. How does that not violate causality or the speed of light? I've read that it doesn't, but I've never seen a good explanation.

>>729666791
Well it does concern physicists. But no one knows why observing particles "collapses the wavefunction". There are many theories on it, but none have yet been verified or falsified. Some think it's to do with the complexity of the system that "observes" the particle(s), and some think every time you observe a particle, you create a whole separate universe, where your value for the particle is true. We just don't know. But that's why we study physics isn't it?

Will I get a job with a bachelor in physics?

>>729662381
If law and effect exist, how can there be free will?

Is there an assumption that quantum mechanics follow some yet unknown rule?

>>729667297
yes

>>729667030
It doesn't violate causality because you can't actually transmit information faster than light. When you entangle, the particles, you have created the system and its possible values are already determined. Separating them means nothing. The information is already there, but looking at it determines which exact value it takes.

>>729664933
Topkek

>>729667376 Not OP here but a cracked out attack helicopter who wanted to say something. Basically it's as if you have a die and you are going to roll it, although you know it will be (for d6) a number between 1 and 6 you can't predict with 100% accuracy what it would be. So then you say, well if you know all parts of the environment and of the roll of the dice maybe it no longer exists. Which pretty much means that God (something all knowing) would negate free will but they are always busy fucking hookers and we're too stupid to ever know 100% every single part of the universe so relatively we have the illusion of free will, and it might as well be until we become God.

>>729662381
Is it possible to create something out of nothing? Explain please.

>>729662381
Where in the mathematical equation does it break when you want to "observe" light but then it act like a particle or a wave?

>>729667376
Free will doesn't exist, but determinism also doesn't exist. You brain functions fundamentally on quantum particles. Their behaviour is inherently unpredictable, but you have no more control over this than you would over a completely deterministic system. So the non-deterministic nature of your brain does not imply you have free will. And on top of this, your brain is large enough and contains enough particles that it behaves pretty much exclusively in a classical way. I.e. the outcome of an event can be predicted (at least in theory) with perfect accuracy. So it is essentially a deterministic system.

>>729662381

when you use an aerosol as a flamethrower, why doesn't the aerosol ignite inside the can? particularly, while the fluid slows down as you pull your finger off the valve.

>>729668075
Well it's to do with the Heisenberg uncertainty principle. It says something can't have both a well-defined momentum and a well-defined position.
Particles have a well-defined position, so they must have a "fuzzy" or ill-defined momentum.
Waves have a well-defined momentum, but an ill-defined position.
If you have a situation which neither strongly constrains position nor strongly constrains momentum, an object can exist in a kind of in-between state called a localised wave-packet, or a quanta.

>>729668004
"nothing" is a philosophical concept. It means the absence of anything, even "empty" space. As soon as you give something a property, it ceases being nothing. So the short answer is that something can't come from nothing, but the big bang does not imply that nothing exists "outside" of the universe. It implies that there is some form of structure that is separate from the universe, and which the universe comes from. Please don't jump on muh gad.

Yes, in fact I think Feynman came up with this idea. It seems very unlikely, but it is possible. It was given as an explanation as to why no electron can occupy the exact same space and time and quantum state as another electron. So it is possible that there is only one electron in the universe that is in every electron position at once.

>>729664392
how does dark matter bend space time

>>729670260
E=mc^2 and D=ct if c=1 then c^2=1 and: E=m, D=t

So you see that no one says time is a dimension and energy is matter, but with a factor of c they become mathematically equivalent. They are distinct for a reason, but they behave mathematically very similarly to each other.

I believe people have very good emotional reasons for believing in god, but if there is some prime creator of the cosmos (which no one can disprove) then it is certainly nothing to do with human concepts of god. It doesn't give a damn about life and it certainly doesn't offer life after death. If you believe there is something "more" then you aren't appreciating fully what "is".

>>729670626
The exact same way normal matter and energy bend spacetime. It's just that it doesn't seem to interact with any other the other fundamental forces. Could interact with the weak force if it is some form of exotic neutrino, but we don't know as of yet. Hopefully the LSST will shed more light on this.

Nice trips. To be honest, they could look completely different. I could make up my own symbols and say it means the exact same thing.

>can do an alright amount of math?
No I dont know very much about math at all. The farthest level of math I got in school is high school algebra and I barely passed that and have since forgotten it. On my own studying CS books I wonder what these runes mean so I skimmed though some math books until I find what looks like similar stuff like it looks like some of these symbols come from linear algebra books and some other symbols look like they are even from high school algebra books chapters about binomial and series sequences something. But the books never really connect that to what's in the CS books its like there is a link missing in the chain.

>>729665090
A QM particle travels all possible paths exactly once. Given two slits, a QM particle goes through both. Assume there is no QM field biasing the system. Then the particle goes through both slits an equal number of times (paths). Assume an observer is introduced. This dramatically increases the number of paths through both slits (to values like 10^10^10^10^10^10). It's possible but extremely unlikely that there is still no bias. It's very likely that >99.9999% of the paths are through one slit, hense the "collapse".
