Question

the big bang theory is the best explanation that we currently have about the formation of the universe. what makes it a scientific theory? * 1 point
○ it is a scientist’s initial idea or statement
○ it explains the natural world as we know it
○ it has been tested over and over again withstanding the falsification process
○ it is a fact and for all our purposes it is seen as \true\

how does the big bang theory suggest that the universe started? * 1 point
○ from a very hot, dense, singular point from which the universe expanded
○ a large collision of two cosmic objects that created the universe
○ a huge explosion that caused everything we know of now in the universe to form
○ none of the above are what the big bang theory states

Explanation:

First Question:

A scientific theory is well - tested and withstands falsification. A scientist's initial idea is a hypothesis. A theory explains but the key is rigorous testing. A theory isn't a fact (facts are observations, theories explain). So the correct option is the one about being tested repeatedly.

The Big Bang theory states the universe began from a very hot, dense singularity that expanded. It's not a collision or a typical explosion. So the correct option is about the hot, dense singular point.

Answer:

It has been tested over and over again withstanding the falsification process
