If you want t9 learn it. You have to do the exercises.

Well we have recreated an asymmetry in the lab…kaon oscillations…but it’s not strong enough to match large scale observations
2
No, it’s there. Maybe just “slightly annoying” tho. I have a relative who does it, and it bothers me. I think it’s a feminine way to talk, in that women do it more when explaining things. Great . Now it irritates the 🩸E F out of me.
2
You from andromeda? Right now that’s roughly when it is on earth there.
2
Can you timestamp the biggest offense? I don’t see crap, and I see other comments sayin this content is 💩, and just do. Not. Get. It. Why y’all complaining?
2
It’s Mankind.

Found one.

Search for the Einstein source, irc. It shows massive positron anhilation spectrum
1
Also, when it’s really hot anhilation and creation are in equilibrium, so stuff is created as fast as it’s destroyed
1
So we’re black holes.
1
Antimatter was observed in 1932
1
What are you talking about?
1
This guy is creepy af.
1
Why?
1
light travels perpendicular to its phase fronts. Those are lines of simultaneous phase.
1
She misspoke for sure. That is how the positron was discovered, though …in 1932, on mt wilson
1
I was married to a particle physicist. She just didn’t care about this stuff
1
Time stamp?
1
Doesn’t dark matter dominate entropy?
1
Why: because it’s a lot simpler than not being this way. When quantized, it enforces particles be boson or fermions, with the latter being matter.
1
I think you just covered. If time goes backwards, all futures point to a singularity, all directions lead to it…like inside and event horizon. Moreover, cosmic expansion means there is a horizon we can never reach…just like in a black hole
1
He didn’t explain that part too well, but if you look at positronium decay to two gammas, it’s the same as Compton scattering in a precise mathematical way.
1
Doctors put antimatter in your brain to anhilate part of it….way worse than injecting bleach
1
Me too. Such a dumb question is hard to forget.
1
so I like ppl who make clear problems. 20:50, you have numerical labels on "t" that are ordered, while having numerical labels on on particles, which are partially ordered, but no really. You have got to set problems up more clearly---I see more and more of this.
1
Wow, you even failed on newtons laws there
1
@kyle1562 velocity is not additive, but rapidity is. At slow speeds, they look the same to many digits.
1
@kyle1562 v/c = tanh(w) where w is omega (rapidity). You can use the hyperbolic trig identities to show that: w" = w + w' is the same as the standard velocity addition formula: v" = (v + v') / (1 + vv'/c^2) so in your example (in SI units): v" = (5+2)(1 + 10/c^2) = 6.999999999999998 m/s which differs from the Newtonian result by 1 foot per million years.
1
@kyle1562 c is always the speed of light, as in E = mc^2
1
But antimatter is charged, and charges couple to light, so it’s not dark
1
I don’t get it. I used to look like the CMB: almost perfectly smooth, and now I am a sack of low entropy, eating ordered food and making disordered 💩.
1
How do you think she feels about it?
1
1:09:20 Brian is so far off base here, at least as far as his pun is unintended.
1
I don’t know what he’s referring to
1
Undulating waves of probability really gives the wrong idea, even to ppl who study this stuff. The probability can be fairly smooth and uniform, but you have a complex undulating wave of probability amplitude under the hood-the phase- and that is where all the quantum woo happens, since we can't know the phase, we just see the smooth not undulating probability. We can't know phase, though we can know at how fast a rate phase changes in time and space---in fact we've even given those rates special names, without even knowing what we were doing: energy and momentum.

Leave out many worlds and strings, and it’s just as good
1
Can you just not? This is about blackholes
1
Because it’s exothermic. And the symmetry between them means everything that needs to be conserved is conserved.
1
Antistars would look just like stars in the EM spectrum, but they would emit antineutrinos as they turn antiprotons into antineutrons in the core
1
I guess that’s low entropy.
1
She’s not a theorist. She went out and found a blackhole. That is a different skill set from oooing an ahhhing over warped spacetime.
1
1:13:00 wait. This guy admits he thought Biden was mentally competent until has saw a debate in which they withheld his “medicine”? You cannot take anyone like that seriously ever again. Sorry, I’m out. And he’s creepy.
1
Timestamp? Or else..wat?
1
No anti gravity bc squares of numbers are alway positive. No flubber bc energy isn’t created, tachyons are whack, and so on
1
Physics isn’t that hard, actually. If you do it for a few decades it’s the same ol 💩.
1
No, charge needs to be conserved, as does baryon number. So far. Baryon number may break at some point.
1
Dirac eq is e=mc2 in the language of quantum operators instead of classical numbers
1
Perhaps the stupidest comment in the whole lot.
1
After estrogen therapy.
1
Too dangerous. Could be misinformation!
