Is Nature Converting Mass Into Energy Anywhere In The Universe?

Question

Except In Supernova And The Birth Of Black Holes

Answer 1

yes, every star converts mass into energy. During fusion (which all healthy stars go through), hydrogen atoms are pressed together to form helium. The helium ways less than the hydrogen it's made from; the excess mass in converted into radiation we receive as light and heat.

Answer 2

Just my own thought, i think we humans are the machines that nature uses in converting mass into energy. We put together different masses of things into a compound or another form mass suitable for our consumption or as fuel to sustain our body with energy to do our daily task and errands. Same with plants.

Answer 3

Mass does not change its religion. When a mass moves it is said to have energy.
Energy is a power transfer process. It is equal to the product of the quantity of the moving mass and the velocity square that its moving at.
A bruned out star is not a totally dead star( it just means nuclear fusion has decayed to a low level. nor is it a black hole:if black hole actually exist its only a scientific supposition.

Answer 4

Doctor_e99 is correct. However, I would add one more source and it is happening here on earth.

Nuclear fission is occurring all the time as heavy metals decay into lighter ones. This is why inside the earth is so warm. Remember we are living on a massive nuclear reactor and if it wasn't so the Earth would not be habitable.
