Black holes

What is an accretion disk?

• a disk

• found in the black holes

• an event horizon

• a structure formed bu the diffuse material in orbit around a massive central body like a start or black hole

The minimum speed needed to a free object to escape the gravitational influence of a massive body

• escape veolocity

• accrection disk

• gravitation

• whirlpool

Formed when star explodes

• minature black hole

• supernovea

• fusion

• nova

NGSS.HS-ESS1-3

System where there are two astronomical bodies that are close enough that their gravitational attraction causes them to orbit around each other

• system

• earth and sun

• 2 star system

• binary system

NGSS.HS-PS2-4

The point in the center of the black hole where we believe that physics as we know if may cease to exist

• accretion disk

• singularity

• supernova

• quasar

A neutron star is

• an extremely dense mass of neutrons formed at the core of a supernova; neutrons are formed by the compression of electrons and protons

• a bright star in the North pole

• a dense star in the center of a black hole

• I have no idea

NGSS.HS-ESS1-3

A region in spacetime beyond where events cannot affect an outside observer, this is the point at which there is no return and time is said to standstill

• accretion disk

• even horizon

• supernova

• escape velocity

We can see black holes because

• light can escape it

• energy can escape it

• I have x-ray vision

• we see the light of the stars at its event horizon, they reflect off of objects around the accretion disk

Supermassive black holes are thought to be in the center of our galaxy (the milky way)

• true

• false

Astrophysicists believe that miniature black holes may have formed when

• during the big bang

• during a red giants collapse

• when the dinosaurs died off on earth

• from a nuclear explosion in space
