Singularities are infinitely ____ and infinitely ______
Small and dense
Free
Frreee
what is 6(7)-1
41
Nothing is proven, it is only not_________yet
disproven
1+1=
2
If you said 67 as your final answer, plus 800 points(-800 if you're winning)
What did our universe originate from?
A singularity
Describe the recombination
The recombination of electrons with the atomic nuclei that happened 380,000 years after the Big Bang at 2.73 Kelvin
Name one man-made element and its atomic number
double points, 111-118 are okay, but not 112
Stars get their energy from Nuclear_____
Fusion
UV rays to gamma rays are ____ radiation
Ionizing radiation (double points)
+100 if wrong
What is Deuterium
Deuterium is an isotope of hydrogen with 2 neutrons instead of one
The Big Bang created how many elements
(2x if you can name all of them)
3, maybe 4
hydrogen, helium, lithium, beryllium
Explain the cosmic background radiation for 300 or Hubble's Law for 300. If you do both, you get 900 points but I will be a lot more strict
I will decide (remember: Hubble's law, not Hubble's observations) Hubble's Law: The farther something is away, the faster it will move away. Evidence: Hubble observed 22 of 23 galaxies were red shifted. Cosmic background radiation: Light from the recombination is red shifted as the universe expands, there is a background of microwaves permeating the space around earth.
If Jimmy fought an alligator to make his 6th or 7th sandwich, where was he most likely
Easy Question!!!
FREEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE
600 points (Unless you're winning. If you're winning by a lot, -500, if you're winning by less than 301, -200
What is the formula for density
d=m/v
density = mass divided by volume
Another name for accretion disc is...
Proto-planetary disc
What are the three lines of evidence for the Big Bang
Hubble's law, elemental abundance, and cosmic background radiation
What does the weak force do?
It changes protons into neutrons and neutrons into protons
Stars created elements up to this element. Name its name or number to get it right. Also name the time period of the recombination and the temperature it happened at.
Iron(Fe), 23, 380,000 years after the Big Bang, 2.73 Kelvin
Recite the variables for the Drake Equation (doesn't have to be in order) as well as its creator and what the variables mean
(triple points)
R*, fp, ne fi, fc, fl, L, N
R*=number of stars being formed each year in our galaxy, fp=number of stars with planets, ne=fraction of planets in the habitable zone, fl=fraction of planets that can develop life that do, fi=fraction of planets that develop life that develops intelligent life, fc=fraction of intelligent life that develops the ability to communicate, L=lifetime of such a civilization, N=number of civilizations that can communicate with earth.
An accretion disc is a disc because...
It is flattened from a cloud into a disc by angular momentum
What was the order the forces separated from the unified force and what are the steps of the scientific method for double points
Gravity, Strong Force, and Weak and Electromagnetic forces separated at the same time.
Observations, questions, research, experiments, hypothesis, analysis, conclusion (100 if you messed up the last two for the Big Bang)
If Jimmy has 67 sandwiches, and his friend Jerry eats 6.7 of them, how many sandwiches does Jimmy have
60.3
The earliest stages after the Earth was made was called the ____ period
These events created the rest of the natural elements, tell me their name and how they happen
Hadean, Supernovae formed when a star dies
200 if you only at least one right, -500 if both wrong, +1000 if all three right
