This is an amazing article about fire. Read it.
The universe is unbelievably big - trillions of stars and even more planets. Soo... there just has to be life out there, right? But where is it? Why don't we see any aliens? Where are they? And more importantly, what does this tell us about our own fate in this gigantic and scary universe?

Ben Affleck is going to be the best Batman of all time. Not a joke.
Another great lecture from the sometimes-too-enthusiastic NGT.
Hurray for Brad Bird.

How Hot Can It Get?
My notes :
15 million K - THE SUN
The sun is 93 miles away from Earth
Surface of the sun is 10,000 F or 5500 C
The center, where fusion happens, 28 million F, 15 million C, 15 million K
Kelvin at 0 is absolute zero
If you were to heat only the head of a pin to the temperature of the sun, it would kill anyone within 1,000 miles of it.
If you want something to be the right temperature to glow in the visible spectrum, you'll have to reach the Draper Point.
Draper point - 798 K. At this point, any object will glow a dim red.
Objects emitting heat, emit wavelengths.
Wavelengths get smaller and smaller, the hotter, and hotter the object gets.
When matter heats up as hot as the sun, matter becomes a fourth state : PLASMA
PLASMA - when electrons wander away from the nuclei.
350 million K - center of thermonuclear explosion
3 billion K, or 3 gigakelvin - Star 8 times larger than our Sun, on the last day of its life
1 terakelvin - the electrons, hadrons, protons neutrons, melt into quarks and gluons
Star named WR - 104 : mass equivalent to 25 of our suns.
When it dies, the explosion will amount to the energy our sun makes in its entire lifetime.
Even at 8000 lightyears away, 10 seconds of WR-104's explosion could deplete 1/4 of the Earth's o-zone, leading to mass extinction.
1 exakelvin - CERN's particle accelorators
1.4x10^32 K - the plank temperature. the wavelength is the plank length or plank distance. We don't know what would happen if it got hotter than the plank temperature.
Kugelblitz - a black hole made from pure energy.
The sun is 4.7 billion years old, half-way through its life-cyle. So far, it has burned the energy equivalent to 100 Earths.
The sun is the size of 300,000 earths.
Technically true: one cubic cm of human is hotter than one avg cubic cm of the sun.
