Some definitions:
1) Evolution
All life on Earth evolved from a single-celled organism that lived roughly 3.5 billion years ago.
2) The earth is round
The earth is a sphere.
3) The Big Bang
The universe started as a singularity with infinite density and expanded from there.
4) All people originated in Africa.
All mankind originated in Africa and migrated to all the other continents from there. This map shows the approximate time period based on actual fossil records that were carbon dated.
5) Einstein's Theory of Relativity
The speed of light within a vacuum is the same no matter the speed at which an observer travels. As a result, he found that space and time were interwoven into a single continuum known as space-time. Events that occur at the same time for one observer could occur at different times for another. As he worked out the equations for his general theory of relativity, Einstein realized that massive objects caused a distortion in space-time.
6) We are all star dust
Stars create new elements in their cores by squeezing elements together in a process called nuclear fusion. First, stars fuse hydrogen atoms into helium. Helium atoms then fuse to create beryllium, and so on, until fusion in the star's core has created every element up to iron. All atoms used to create life were formed in stars.
7) There are over a Billion galaxies in the Universe
There are approximately 100 billion galaxies in the Universe. Our galaxy, the Milkyway is just one of those galaxies and contains 100 thousand million stars like our sun.
These are just some of the basic concepts of science that ALL Scientists believe to be true.
