Rocket | Science
Here, it probably IS rocket science. A place for me to discuss astrophysics and space exploration, although other sorts of science, math, and technology are likely to make appearances.

spaceplasma:

On August 24th at 12:17 UT, NASA’s Solar Dynamics Observatory recorded this M5.6-category explosion near the eastern limb of the sun.

The source of the blast was sunspot AR2151. As the movie shows, an instability in the suspot’s magnetic canopy hurled a dense plume of plasma into space. If that plasma cloud were to hit Earth, the likely result would be strong geomagnetic storms. However, because of the sunspot’s location near the edge of the solar disk, Earth was not in the line of fire.

Even so, the flare did produce some Earth effects. A pulse of extreme UV radiation from the explosion partially ionized our planet’s upper atmosphere, resulting in a Sudden Ionospheric Disturbance (SID). Waves of ionization altered the normal propagation of VLF (very low frequency) radio transmissions over the the dayside of Earth, an effect recorded at the Polarlightcenter in Lofoten, Norway: data.

earthstory:

Earthquakes take place at times that are basically random, but they occur in specific locations around the world defined by plate tectonic boundaries. If you ever wanted to understand what that means, head through this video; it shows every detected earthquake above a certain size limit over a 4 month period.

The month of April actually had a series of large earthquakes worldwide, but you should get a sense of how that can happen just by random chance from watching this.

What are the units?

There are many kinds of the net of the tesseract.

Hawking radiation mimicked in the lab
Sound waves used to imitate light particles predicted to escape black holes.
Scientists have come closer than ever before to creating a laboratory-scale imitation of a black hole that emits Hawking radiation, the particles predicted to escape black holes due to quantum mechanical effects.
The black hole analogue, reported in Nature Physics1, was created by trapping sound waves using an ultra cold fluid. Such objects could one day help resolve the so-called black hole ‘information paradox’ - the question of whether information that falls into a black hole disappears forever.
