What is the differential pull of the moon on the
Earth?
14
These are extreme tides that occur when theMoon,
Earth, and Sun are aligned as in a new moon anda
full moon.
Find out the answer
15
What are Spring tides.
16
This causes one high tide to be an additional 25
minutes later thanjust 12 hours from the
previous high tide.
Find out the answer
17
What is the amount of revolution of the moon
around the Earth in 12 hours?
18
The sun exerts a much larger force on the Earth
thandoes the moon, but the difference between
the force on the near and far side of the Earth
is greater for the Moon than the Sun.
Find out the answer
19
Why does the Moon effect the tidesmuch more than
the Sun?
20
The sphere surrounding a black hole where the
escape velocityequals the speed of light.

21
What is the event horizon?
22
This name refers to black holes that could
nothave been formed from a star. It is believed
they can be foundat the center of every galaxy,
have a mass of billionsof suns and are
responsiblefor holding the galaxy together.
Find out the answer
23
What is a super massive black hole?
24
These are streams of particles shooting out at
near the speed of light and directed as if they
were emitted from the center of the black hole
perpendicular to the disk of debris orbiting the
black hole.
Find out the answer
25
What are jets?
26
This is the name given to the material orbiting
and spiralingAround a black hole.
Find out the answer
27
What is an accretion disk?
28
This term was coined to mock the concept by
Hoylewho didnt believe it was true, but the
term stuck and is nowthe name we give to the
theory of the creation of the universe.
Find out the answer
29
What is the Big Bang?
30
This phrase describes the fact that galaxies that
are far away are moving so fast away from us
that their light appears to have a lower
frequency and longer wavelength than we would
normally expect.
Find out the answer
31
What is red shift?
32
This is the name given to the constant of
proportionalitythat relates how far away a
galaxy is to its speed relative tous. This
constant is somewhere between 50 and 100 ( km/s
) / (Mega parsec).
Find out the answer
33
What is Hubbles constant?
34
This object, discovered in 1974, and
namedEinsteins cross is a great example of this
phenomenon.
Daily Double!!!

35
What is gravitational lensing or The bending of
light by gravity?
36
If the mass of the moon was doubled and keptin
the same location, then this number
woulddescribe how much stronger the force of
gravityof the moon on the Earth would be.
Find out the answer
37
What is 2?
38
The Universal Gravitation law (and other
mathematically similar laws) is know by this
Descriptive name because it has the Distance
between the objects squared in the denominator.
Find out the answer
39
What is the inverse square law?
40
This is the answer you get when you plug in your
mass, the mass of the Earth, the radius of the
Earth, and the value of Ginto the universal
gravitation equation.
Find out the answer
41
