You experience no acceleration inside of a warp bubble-no relativistic effects occur to you, and thus you aren't limited by a lorentz transformation. you can't follow paths that lead to absurdities like time travel due to quantum feedback effects-it's like trying to go north of the north pole.

Alcubierre warp drive isn't about traveling faster than the speed of light, it's about shifting space around an object so that the object arrives at it's destination more quickly than light would.

My apologies, I was not aware of this.That being said, I was referring to exclusively dark matter.

Although this is an interesting theory, what I stated still holds. There is currently no proof of negative energy. This theory has not been tested yet. I agree that negative energy is a possibility. If it moves past validity as a theory and into truth, then the Alcubierre Drive is absolutely possible, but until that is determined, it's a big maybe.

it really does feel like that sometimes. Yo know when you spend all week playing video games or browsing 4chan and all the time just melts into one single blob? Or when you see a really high quality colour photo of many years in the past and realise that the gap between now and then is only in your mind? Or the opposite where you take some weird drug and time seems to go on forever or even stop. These feelings have started to scare me because the gap between now and my eventual death doesn't exist either. I am already dead.

He meant that the rate of the passage of time is just a measure of how fast particles changed, essentially time being the wavelength of physical matter. Since the human brain is made of matter, ohr perception of time is innately determined by the time dilation of said matter, and that without perception and comparison it is wholly meaningless and functionally instantaneous. There is no baseline speed of time because its wholly relative to one particle relative to another.

1st yr engineer student here. I feel at a crossroad because modern engineering is so removed from pic related and it's all about software/data/etc. Old school shit where you design a machine and build it is fading away. Part of me wants to switch to trade school/vocational school to do something more practical but at the same time, theoretical shit like math etc does fascinate me. However, out of college the jobs are so much more about coding and data which doesn't feel as rewarding to meas seeing the work of your own hands physically .

You won't, especially as a low level engineer. No one will trust you with design. It should "feel" more practical as you continue on in engineering school. If you want to dip because your not good enough to be an engineer, trade school isn't a bad option but if you are good enough to be an engineer and you don't do it you will probably regret it.

Same here. Just finished my MSc in Chemistry. Seems like a shitty life decision. All the jobs I seem to be able to get are Labtech jobs with atrocious pay for my qualifications and absolutely no possibility for future development. I have a publication, presented at an international conference etc.. But it don't matter.
Might have to bite the bullet and just do a PhD after all. Although I am competent, the passion for this whole science stuff has faded. And then the job hunt is porbably much harder since everybody has one by now. If I could just do smth with my current degree that would actually pay I'd just grab the opportunity and get into passive income/trading/whatever I need to do to maybe one day not needing to work at all. B-but at least I am at 2.9/4.5/5.25 right.

COMMENT: The basic ideas here is that computation is primary, and the discovered part of mathematics is the behavior of computer programs. Mathematics is real when it is stating a prediction for a computer program behavior (either a theorem, a conjecture, or a real example), and it is ambiguous when the content can't be stated as the behavior of a program (like the continuum hypothesis). This point of view is out of fasion today, but wrongly, so I defend it.

I will use the elementary school definition of area as the number of unit squares you can fit into it.
We have a rectangle with dimensions a,b and we want to prove its area is a*b.
Let's first assume the rectangle has natural number dimensions a,b.
Assume the height b is 1. Then we simply stack up a squares horizontally to fully fill the rectangle.
Now if we increase b we just add one new such row, so the answer is a more. By induction, we have the area is A=ab.
Now assume the rectangle has rational number coordinates.
a=p/q, b=s/t, p,q coprime, s,t coprime.
We stack up q such rectangles horizontally and stack up resulting figure t times vertically, to get a rectangle of width p and height s. Its area is ps.
But each smaller rectangle which makes up the big rectangle is congruent and so has the same area. Since there are qt such rectangles, the resulting area of an individual rectangle is ps/qt = ab.
Since the real numbers are fake we won't bother with them.

OP takes penis up his ass. The thickest part of the BBC that fucks OP can be represented by a circular trace, pi * r^2. This trace is obviously in units of length squared (A = 1/2 b * h, b = 2pir, h = r). Now, how do we know for certain that this trace exists in the first place? The area around OP's prolapsed sphincter can be calculated using pi * r^2, which is the formula for area that we previously stated. If we let r = 7 inches, we see the area of OP's sphincter after he gets fucked by his boyfriend Rodney. Attach a Desmos slider from r = 7 to r = 12, you've got OP's sphincter on a typical Friday night.
