What is the big bang theory?
A theory that states that the universe started in a large mass and then imploded to form everything.
A theory that states that the universe was there, will be and is there. Is homogeneous and isotropic.
A theory that states that the universe is slowly coming back to a center.
A theory that states that the universe started in a small mass and then expanded, the expansion cooled down the temperature and that resulted in the formation of matter, energy, space and time.
What were the original two elements in our universe?
Hydrogen and Lithium
Helium and Oxygen
Helium and Hydrogen
None of the above
The red-shift in the spectral lines of light, reaching us from other galaxies implies that these galaxies ____________.
Are moving closer to one another
Are moving farther apart from one another
Are in rapid rotation
Redshift doesn´t exist

Multiverse Theory
Big Bang Theory
Steady State Theory
Cosmic Inflation Theory
When did the big bang occur?

How is the universe analogous to a rising raisin bread dough (or, like a balloon with dots on it)?
As the dough sits there, the raisins becomes smaller and smaller.
As the dough expands, the raisins bunch up together.
As the dough contracts, it becomes ready for the oven.
As the dough expands, the raisins move further apart from each other.
This is leftover thermal energy, or an echo, from the big bang.
red shifting
cosmic microwave background radiation
expansion
dark matter
What is the universe?
Everything you can see
Everything that exists
My crush
Watching KDrama
The steady state theory holds that the universe:____
Looks essentially the same from every spot in it and at every time. It is homogenous and isotropic in space and time. It has uniform density so matter is continuously created.
Is homogeneous and its density is uniformly distributed. At the beginning the tiny dot expanded and spread out all the universe´s density.
Is a black dot that expanded to form all space, matter, time and energy. It is continously changing and it probably is going to crush.
None of the above
The arguments supporting the Big Bang theory mostly contradicts some of the Steady State theory. Matter is created out of nothing and the neverchanging universe is refuted by: _____
Light from distant galaxies will get red-shifted, the wavelengths of light they're releasing will get longer, and thus redder.
Light from distant galaxies will get blueshifted, the wavelengths of light they're releasing will get shorter.
The law of conservation of matter states that matter is never created or destroyed, it is only transformed from one state to another.
None of the above
The term big bang refers to _______________.
The origin of the universe
The ultimate fate of the universe
A supernova explosion
The formation of a quasar
The universe is mostly made up of
dark energy
dark matter
ordinary matter
forces
