Theorem of a Supernova - The NuSTAR Mission
NuSTAR has provided the first observational evidence in support of a theory that says exploding stars slosh around before detonating. That theory, referred to as mild asymmetries, is shown here in a simulation by Christian Ott of the California Institute of Technology, Pasadena.
In this simulation, a supernova explosion is already underway. The small circle in the center represents the material that will form the dense star at the center of a supernova remnant, called a neutron star. The bright ring surrounding it is the shock wave created in the explosion. The colors represent temperature fluctuations. When the movie starts, the explosion has “stalled out,” because the material falling back onto the neutron star has backed up, like too many cars on the freeway, blocking the shock wave from progressing.
As the explosion continues, material starts to slosh around, reenergized by particles called neutrinos. The neutrinos heat up the material more and more, causing the hot regions to rise into the cooler regions and form large bubbles in the material. Once the bubbles break through the surrounding material, it’s as if the top of a pressure cooker blows off. There’s nothing holding back the shock wave any more and the star explodes.

At first I thought this was a cell, seen under a microscope. It’s funny how something so big can look like something so small.

I attended an “empowering women” sort of seminar and they taught us to use the phrase:

I’m sorry my success bothers you

If people were making snide comments.

Hello! Do you know where I can purchase the t-shirt with a scientific equation on the front, which Benedict is wearing in his Ice Bucket Challenge video?

wearsherlock:

Hi! Sadly we haven’t been able to identify it yet, only that the equation is (as many have already pointed out) for the Bekenstein-Hawking entropy of a black hole:

There also appears to be some kind of diagram on the back of the shirt - if there are any astrophysicists out there who can identify it, please get in touch!

Wait wait wait
So a couple hours after Benedict did the ice bucket challenge, I realised that ALS is also called motor neuron disease, which is the thing Stephen Hawking has. And Benedict has played Stephen Hawking. So his shirt was an oblique shout-out to Stephen Hawking? Damn this guy is clever.

In the model you can change the number of dots and the deviation too. If you set the “type demo” to dynamic it will make possible to analyse how the wave-pattern changes when deviation grows.

so you’re telling me there’s an alien who regenerates into a completely random form, that he cannot control or determine himself, and who understandably could take millions of different appearances, but who all 13 times just turned into a different skinny white guy
