The Big Bang theory, a cornerstone of cosmology, posits that the universe began from an extremely hot, dense initial state and expanded over time. One of the key pieces of evidence supporting this theory is the existence of cosmic microwave background radiation, which is a remnant from an early stage of the universe.

How do stars produce elements?

Once the elements are out of the star the star will die. When the star dies and is cooling it will turn into a white dwarf, after that it will then turn into a black dwarf.
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.

How do systems outside of Earth affect Earth?

Final Answer:
As the stars move away from the earth the closer they get to the sun

Why does an object go faster as it gets closer to its star?

Star: is type of astronomical object consisting of a luminous spheroid of plasma held together by its own gravity.
The speed changes for every object that goes around, it depends on the temp and weather.
The farther it is from the Sun, the weaker the Sun’s gravitational pull, and the slower it moves in its orbit.

What evidence is there for the Big Bang?

The theory predicted the existence of background radiation throughout the universe before it was discovered.
