The scientific method depends on…
…organised skepticism, where scientists and rewarded for disproving the findings of others.
At the dawn of the universe, how did new elements form from hydrogen and helium?
Through gravity slowly but surely pulling them together until the collective mass forges new elements.
Which two elements did the universe start with?
Hydrogen and Helium
What is the process called when two elements fuse to create a new element, releasing energy?
Fusion
Which element requires energy to fuse rather than expels energy, thus causing a supernova?
Iron
How did heavy elements like carbon get distributed across the universe?
Through exploding stars (supernovas)
