100
This is what neutron stars are made up of.
What are neutrons?
100
This is the major tenant of special relativity.
What is that all observers agree on the speed of light / nothing can travel faster than light?
200
This is the theoretical last stage of a low mass star.
What is a black dwarf?
200
This is the lightest element that cannot be fused to release energy.
What is iron?
200
This is the name given to a Type 2 supernova.
What is core-collapse?
200
This is how massive a neutron star is.
What is 1.5 - 3 solar masses?
200
This is the name given to the "surface" of a black hole.
What is the event horizon?
300
This is the core temperature needed to fuse helium into carbon during the red giant phase.
What is 100,000,000 Kelvin?
300
This is the distinction between a high mass star and a VERY high mass star.
What is 8-20 masses for high mass, and 20+ solar masses for very high mass?
300
This is the name given to a brief re-ignition of a fusion reaction on a low mass star.
What is a nova?
300
This is how big a neutron star is.
What is ~ 10 mi in diameter, or the size of an average city?
300
This is the name given to the size needed to compress any mass to the density of a black hole.
What is the Schwarzschild Radius?
400
This is the element that makes up most of white dwarf stars.
What is carbon?
400
This element is one possible product of carbon fusion.
What is Magnesium or Neon/Helium (and others)?
400
This is this mass limit for a low mass star before it undergoes a supernova explosion.
What is 1.4 solar masses?
400
This is the difference between a pulsar and a neutron star.
What is all pulsars are neutron stars, but only neutron stars that point their beams of radiation toward Earth are considered pulsars?
400
This is how the gravitational force is explained under relativity.
What is the idea that mass warps the 4D fabric of spacetime, creating pushing forces that appear as gravitational pulling forces?
500
As a red giant evolves, it becomes this object, even though it has nothing to do with planets.
What is a planetary nebula?
500
This is the process that creates heavier elements that iron in high mass stars.
What is photo-disintegration during a supernova?
500
This is the remnant left behind after a 10 solar mass star undergoes a supernova explosion.
What is a neutron star?
500
This is theoretical explanation given to x-ray bursts.
What is pairs of binary neutron stars creating a nova-like release of energy?
500
This is how Einstein proved his theory of General Relativity.
