Understood, but it's still funny.

It still amuses me to no end that we power our high-tech rockets with old lamp fuel.

BOOM BOOM NIGGAS!

RIDE A SHOOTING STAR!

Turbulence.

What's more important is we need to redefine the second in terms of fundamental physical constants instead of the properties of a particular element, ideally such that it will be an exact multiple of the Planck time.

From an evolutionary standpoint, it makes sense that astronauts, some of the most physically fit and capable specimens of our species, would be attractive. Because over the course of their bloodline, that attractiveness would have given them access to the choiciest of mates.

Hey, at around T+2min, it will be visible across most of the US East Coast. Neat.

Heh, Jersey resident here. Inland the weather is projected to be mostly pleasant over this weekend. The state parks have plenty of lovely lakes and whatnot, though it might be just too darn cool to make it worthwhile.

Most of the model guidance places the core of the storm somewhat further offshore. NE could get a soaking sometime midweek though.

Yeah, wind, but no rain.

Unfortunately it doesn't look that way.

Hurricane Hermine has hit the Florida Panhandle:

A cubic liter would actually be 1*10^-9 m^9

As far as we know, it's not a model. Electrons are literally point particles.

Dogs are servants. Cats are companions.

We do know how to warp space: pack a shitload of energy into a small volume, and space will contract around it. It's not like the popsci description, which makes it like some kind of rubber sheet, but I find a useful analogy from the material sciences is soft bodies, like a cube of gelatin.

If you were to imagine that the gelatin were somehow attracted to stuff placed in it, then the straight lines (geodesics) through the plain jello would be warped towards the embedded items. This is not just a conceptual analogy: the very same tensors used to describe spacetime are also used to describe the stress and strain in soft bodies.

Actually, scientists believe that no one actually domesticated cats. They just hung around grain storehouses and slowly domesticated themselves as the most adorable ones were the ones more likely to get additional food and belleh rubz.

Something like this would cool off the object to the wet-bulb temperature instead of the dry-bulb temperature, but I think in a freezer that wouldn't be much help because the RH would be close to 100%.

No, the Schwarzschild radius IS the radius of the event horizon sphere for a given mass. We don't know what size the actual singularity would be, assuming it has a property we could even call a size in the conventional sense.

Gaston is expected to reach hurricane strength today:

It's a purely classical thermodynamic analysis. Which goes to show just how much that breaks down at these scales.
