Origins of Black Holes: Gravity at Its Extreme
Dr. Feryal Özel, Associate Professor, Astronomy/Steward Observatory, University of Arizona. Presented March 1, 2011. Gravity is the most important force in the universe, holding together planetary systems, stars, and galaxies. It is what makes the stars hot enough to shine and what keeps the Earth close enough to the Sun for life to form. It is also what ends the life of every massive star with a spectacular collapse and the formation of a black hole. Finding and studying hundreds of black holes within the Milky Way and in other galaxies brings us closer to understanding gravity at its extreme. Cosmic Origins is the story of the universe but it’s also our story. Hear about origin of space and time, mass and energy, the atoms in our bodies, the compact objects where matter can end up, and the planets and moons where life may flourish. Modern cosmology includes insights and triumphs, but mysteries remain. Join the six speakers who will explore cosmology’s historical and cultural backdrop to explain the discoveries that speak of our cosmic origins. cos.arizona.edu

I want to check voltage to a hot tub motor. There is a white, a red, a black, and a green going to the motor. ?
Question by Buzzie8: I want to check voltage to a hot tub motor. There is a white, a red, a black, and a green going to the motor. ?
I think that I should get 120 volts if I probe white to black or white to red. Should I get 240v if I probe red to black? I know green is a ground. Also, are there any wires that I should not probe together with my volt meter?

You’ve got it right. !20 between neutral (white wire) and either of the hots ( black and red wires) and 240 between the two hots.

Mysterious Black Holes
Mysteries of Deep Space: Part 4 of 6. In the fold of our home galaxy, the Eagle Nebula is one of the richest of the great star nurseries. Intense stellar winds have sculpted a majestic castle of gas. Inside these giant columns, stars are being born. Yet for the dying stars that set this process in motion, the consequences are grim. Supernovae leave in their wake a range of bizarre objects. Among them, tiny ultra-dense objects called neutron stars, and their strange, other worldly cousins, black holes.

Question by : Let me clear something up for people who are mad the the “Green Lantern” is going to be white and not black?
Ok, there are many green lanterns, every time the old Green Lantern dies, as he is dying he gives it to a new person, so yeah at one point in time it was black, but this one is when he was white.
All you people who thought “racist”, are stupid and know nothing about comics.
