Large Boom Theory
The actual name of the theory that the universe began as a single primordial atom, a "hot/dense state".
What is the "Big Bang Theory"?
This is the name for the energy that is allegedly causing the accelerated expansion of the universe.
What is dark energy?
This is the weakest of all the universal forces.
What is gravity?
This was Einstein's "biggest blunder".
What is the cosmological constant?
This is the name for the incredibly large expansion rate at the very beginning of the universe.
What is inflation?
The four-word name for the energy that Penzias and Wilson found, which over time and space has been stretched into a larger wavelength during universal expansion.
What is CMBR or Cosmic Microwave Background Radiation?
This is the name for the "missing matter" in the universe that cannot be observed directly through any means we have yet developed.
What is dark matter?
These are the names of the other three universal forces, not gravity.
What are Electromagnetic, Strong Nuclear, and Weak Nuclear?
Assuming the universe is expanding at the same rate over time, scientists can use this constant to help them calculate the age of the universe.
What is Hubble's constant?
Since we have discovered that the expansion of the universe is accelerating, we now predict that our universe will do this in the future.
What is it will expand forever?
Because of the Big Bang Theory, older galaxies have these two characteristics.
What are Bluer and Brighter?
Darth Vader, Darth Maul, Darth Sidious use this, which sounds like it belongs in the cosmology chapter.
What is the "Dark Side of the Force?"
This is the only force which cannot be unified with the other universal forces.
What is gravity?
This constant is responsible for astronomers being able to measure great distances to other stars and galaxies.
What is the speed of light?
Since the universe has expanded so much, the current shape of the universe appears to be this.
What is flat?
Because the Big Bang happened about 13.8bya, scientists believe that the farthest we can see in the universe is about 13.3 million light years. This is the name for that spherical region beyond which we cannot see.
What is the "cosmic light horizon?"
The time from the Big Bang all the way up to 200 million years later when the universe was dark, before the first stars formed.
What are the "dark ages"?
At high temperatures, these two forces are the first to unite, becoming the same force.
What are electromagnetic and the weak nuclear force?
The cosmological constant is now used for this purpose.
What is dark energy OR it creates an outward pressure helping explain the expansion of the universe?
Due to the major expansion of the universe, we have found the universe is not shaped like these two objects.
What are a sphere and a saddle?
When scientist say that the CMBR is the same in all directions, they say that the universe is this.
What is isotropic?
The WMAP found some things that are truly small and dark, originally predicted to be there by the Big Bang theorists.
What are neutrinos?
This is the force which is responsible for breaking the universal symmetry, giving us more matter than antimatter, one more than one billion particles compared to one billion antiparticles.
What is the weak force?
This theory is the opposite of the constant expansion of the universe. In fact it predicts that the expansion rate has changed over the course of the universe's lifespan.
What is "quintessence"?
The first three elements created in the first three minutes of the Big Bang were Hydrogen, Helium, and Lithium. These two reasons are given for why no heavier elements formed at this time.
What are the expansion of the universe was so fast that it cooled things down so that it wasn't hot enough for them to form?
