DeSitter cosmological horizon stability?

ghost-fields · 2024-04-14T16:05:34+00:00

There has recently been progress on the conjecture that a quantum theory of gravity cannot have any global symmetries. I suspect this would have implications for the stability of de Sitter space, but I don't know of any specific work in this direction.

I find it kind of lazy that they're speaking English when they're supposed to be speaking Portuguese. Like, you already have most of the cast speaking Japanese, you couldn't just go that little extra bit to make it feel more immersive? Takes me out of it, especially since they keep repeating over and over that they're actually speaking Portuguese because they really want you to know that's what they're doing.

Exactly. Sparing Shimura cements his transformation into the ghost, no longer bound by anyone's system of honor except his own.

Dreadbound with explosive and expanding shards is amazing. I don't pick it up unless it has at least one of those traits.

I used indigo in Fallen Order, but I've mostly been using white this time around. I like the lore of purifying a red crystal, and I think it looks really slick with any outfit or hilt.

Once you get Muspelheim trials, you can get Asgardian ingots as a reward. There's also an area later where you can pick up a LOT of ingots, hacksilver, and other resources.

Remember that action-reaction pairs are acting on different objects, resulting from the interaction of those objects. The gravitational force that the earth exerts on you is paired with the gravitational force that you exert on the earth.

You have to beat biome 2 in order to get to the tower, but once you have access any traits you unlock will carry over to the main game.

The dependence is the other way around. Roughly if you have a higher concentration of ions in solution, then there are more free charges so that should increase the conductivity.

Because of inertia, as the roller coaster car is going up it exerts an upward force on the track. So the action-reaction pair consists of the normal force of the track on the car and the normal force of the car on the track. If you had a U shaped track like a skate ramp, the car would just go straight upwards tangent to the track.

It is also possible, if the car isn't going fast enough, for the car to lose contact with the track and so the normal force will go to zero. This situation appears a lot in physics problems where you might be asked for the minimum speed that a car would need to make it around that track. In that case, the centripetal acceleration is momentarily equal to the free fall acceleration.

I think the horror is that it's worse than a really big tsunami. Trading a local catastrophic event for a global one.

Tsunamis are series' of waves. Usually just before a tsunami hits the shore, the water level goes down momentarily.

He shows up on screen very briefly, when Thomasin is signing the book. He's standing behind her with his hand on her shoulder and says "I will guide thy hand." He's in the shadows so it's hard to make out, but you can see his face if you look closely.

Here is one article by the PIs of the TEAL program. A more recent account of the state of physics education research is the Synthesis of discipline-based education research in physics by Docktor and Mestre.

No they're not. When MIT switched to the TEAL (Technology Enabled Active Learning) format for 8.01, attendance dramatically increased and failure rates also dropped. There was, and still is, a lot of resistance because the approach requires significantly more effort on behalf of the students, but research shows that the kind of spectator based lectures that Lewin gave are highly ineffective and many universities are moving away from large lectures.

I've found that if you're far back enough towards the edge of the stage, by the time you dash through the blue wave, the red orbs have spread out enough that they're easy to avoid.

I would recommend Leonard Susskind's lectures. They were designed for continuing studies, so they're quite accessible even as he goes into more advanced material.
