Inbox, #7, Weird (and Worrying) Questions from the What If? neutron star: [noun] a dense celestial object that consists primarily of closely packed neutrons and that results from the collapse of a much larger stellar body. The neutron stars we can observe average about 1.8 million degrees Fahrenheit, compared to about 9,900 degrees Fahrenheit for the Sun. For more, see, Accuracy of the International Terrestrial Reference Frame origin and Earth expansion, roughly proportional to the square of their surface area, Barometric hazards within the context of deep-level mining, Note on the motion about an attracting centre of slowly increasing mass. (Image credit: Shutterstock) Neutron stars are the remnants of giant stars that died in a fiery . 125. Sadly, we don't have the technology to build comet-lowering cranescertainly not in time to help mitigate climate change.

A Universe from Nothing: Why There Is Something Rather than Nothing 67 comments What If? Dig down, and the pressure increases relentlessly. Before you go on a cosmic road trip, feed the residents of New York City to a T. rex, or fill every church with bananas, be sure to consult this practical guide for impractical ideas. Additionally, the star loses a lot of mass in the process and winds up only about 1.5 times the Sun's mass. That was unexpected. The largest class of star in the main sequence, these are highly luminous and have life spans measured in only millions of years, rather than the billions or trillions of years for other star types. Okay, if you insist. They'd need to evacuate quickly; they'd have at most a few months before the station reentered the atmosphere and deorbited. Well, if you hooked it up to a generator, you could use the slowly-descending comet to produce electricity. : Serious Scientific Answers to Absurd Hypothetical Questions As he consistently demonstrates, you can learn a lot from examining how the world might work in very specific extreme circumstances.

Outside of low-pressure domes, the air would become unbreathable for a different reason. Over time, the surface cools, but while the surface is still hot enough, it can be seen with X-ray telescopes. Soda Sequestration March 18, 2014. While a normal black hole has the mass of 9.945e+30 (five times the sun. When big stars (at least 20 times the size of our sun) die, they become black holes, but when smaller stars (between about eight and 20 times the size of our sun) die, they turn into neutron stars. As gravity increases, then air gets heavier. (Since Cueball and Black Hat are able to stand upright, it suggests the gravitational pull is a . Unfortunately, comets would affect the Earth's temperature in another way. Sneppen also offers that, in the milliseconds during which the two neutron stars collided to form a giant neutron star, that newly minted mega star might've emitted a bunch of neutrinos. Water that goes over Niagara Falls, for example, gains enough kinetic energy during the 50-meter plunge to warm it up by about 0.1C by the time it reaches the bottom. At that speed, as long as you were in the right place at the right time, you could snatch it out of the air. 2 What would happen if a neutron star was placed close to the earth? people had noticed that the continents fit together.
