Who developed a model of the universe with the Sun at the center
<u><em>Nicolai Copernicus
</em></u>
The Earth-centered Universe of Aristotle and Ptolemy held sway on Western thinking for almost 2000 years. Then, in the 16th century a "new" (but remember Aristarchus) idea was proposed by the Polish astronomer Nicolai Copernicus (1473-1543).

Answer;
-Explosion of supernovas
Atoms heavier than iron are generally produced by the process of explosion of supernovas.
Explanation;
Many elements heavier than iron or all of the post-iron elements are formed supernova explosions. The amount of energy released during a supernova explosion is so high that the freed energy and copious free neutrons streaming from the collapsing core result into massive fusion reactions, long past the formation of iron.
For elements lighter than iron on the periodic table, nuclear fusion releases energy while fission consumes it. Chemical elements up to the iron peak are produced in ordinary stellar nucleosynthesis. Heavier elements are produced only during supernova nucleosynthesis.
The heart’s electrical system is responsible for making and conducting signals that trigger the heart to beat. These signals cause the heart’s muscle to contract. With each contraction, blood is pumped throughout the body. This happens 24/7 without us having to monitor it all the time so that our heart does not stop.
