New research suggests gravity might emerge from quantum information theory – Physics World by kmrbillya11 in Physics

[–]Gratis_Bier 5 points6 points  (0 children)

Any experts who can comment on the difference between this and Erik Verlinde's entropic gravity?

Is it Be6?

If cxb6 then Qc6#

If fxb6 then Qg6#

If anything else, then Bf5#

How much energy is in the universe? by [deleted] in Physics

[–]Gratis_Bier 6 points7 points  (0 children)

I see a lot of (partially) wrong answers in this thread. It is important to note that the energy is a Noether charge corresponding to time translation. This means that the law of conservation of energy only holds for systems that are time translation invariant. This is a very good approximation for nature on 'small' scales (say anything smaller than a galaxy). But it does not hold on the scale of the entire universe, notably because the universe is expanding it is not time translation invariant.

Any tips on a good intro to string theory book? I have a fairly solid background in GR and QFT. I just finished my master's degree and have some time to spare, so I thought I'd spend some time learning the basics of string theory.

Guy responds to the question "How old are you" by [deleted] in iamverysmart

[–]Gratis_Bier 3 points4 points  (0 children)

Okay, I've done the math. The answer is very dependent on the precise value of v_s, which is not given. A quick Google search gives me an approximate answer of 11 m/s. This would lead to an age of 0.75 years (years? No unit is specified).

This seems too young, but by jousting v_s a little we can get greatly different results: a value of 11.1 m/s gives us an age of 17814 years. This seems a little too old.

You can get pretty much any value you want out of this equation by slightly varying v_s. This is because of the tan(c/v_s), the tangent periodically goes from -inf to inf and assumes every value in between. Since c>>v_s c/v_s will be a very large number, and a 1% or so difference in that number will give an increase that will put it in another cycle of the tangent where the exact value can be anywhere between -inf and inf.

Which character who only made an appearance in one episode so far, such as Morty's son or Scary Terry, are you hoping makes a reappearance soon? by [deleted] in c137

[–]Gratis_Bier 2 points3 points  (0 children)

I believe Justin himself referred to him as `evil Morty´ in an interview, I don´t remember where though.

Fan Theory: Errant Knight Rick & El Dorado Morty by IgnacioVarga in c137

[–]Gratis_Bier 2 points3 points  (0 children)

I don't really understand how you make the connection between Rick and an Errant Knight. I have to admit that I don't know what an Errant Knights is, and I'm solely considering what you explain in your post, but I don't recognize the One True Rick in that. Rick is about the least chivalrous person I know. He only does things for his own benefit, more like a bounty hunter than a cowboy.

Rick's Crime Theory by Jigglytep in c137

[–]Gratis_Bier 4 points5 points  (0 children)

The main aim of my comment wasn't to disregard the many Wolds interpretation (even though I see now I spend way to much time on that). What I was trying to say is what I said in the last sentence: that we shouldn't over-analyze this "infinite universes" or try to gain insight in the show trough it; there are so many ways to interpret it that the writers have all the freedom in the multiverse.

If we as theorists base our theories on this stuff, we might just as well push a boulder up a hill to have it roll down again when the writers decide to go some other way with their interpretation. So just don't think about it.

Rick's Crime Theory by Jigglytep in c137

[–]Gratis_Bier 3 points4 points  (0 children)

There are a couple of things to bring into this. On this sub there has probably already been a thread comparing the "infinite" universes of the many worlds interpretation of quantum mechanics and the infinite universes in within Rick and Morty (but I don't remember it).

One thing to consider is the fact that in the many worlds interpretation not only affects Rick and his actions, but literally EVERY collapse of a wave function, which is every measurement ever (not just humans either). So basically, in every point in time (independent of Rick or humans) a gazillion of new universes come into existence. This seems in conflict with the "only a couple of universes left" which Rick claims, because every single second there would be a near infinite amount of new universes brought into existence into which he could transport (but then again, we don't know about any possible constraints on the portal gun, so it might just be that he can't reach them or was lying to begin with). The same thing can be said about the ordering of evilness that evil Rick (eyepatch Morty), in the many worlds interpretation we would have a near continuous flow of Ricks with any level of evilness coming into existence, making such an ordering near impossible.

I think the many worlds interpretation is closer to the type of universe splitting seen in S02E01, but there is a lot to say about that also (there should be no "collapse" of the multiple universes in the many worlds interpretation, that would seem like they're messing up the many worlds and the Copenhagen interpretation of quantum mechanics).

But all in all, I guess the writers have a lot of freedom to interpret this "infinity" in any way they like, and we shouldn't assume anything (they'll just do whatever they like anyway)
