Answer:
3.42e+58J
Explanation:
Energy E=mc^2
C=speed of light=3*10^8
m=mass
Note that each planet contains 10^11 masses of the sun.
Energy released = (10^11*1.9*10^30)*(3*10^8)^2
Therefore, Energy released by the matter=1.71*10^58
And the energy released by the antimatter is also 1.71*10^58
Therefore total energy released by both matter and antimatter= (1.71+1.71)*10^58
=3.42e+58J
The total energy released if a matter-antimatter galaxy pair annihilated will be 3.42e+58J.
What is a galaxy?
A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems. A galaxy is held together by gravity. Our galaxy, the Milky Way, also has a supermassive black hole in the middle. When you look up at stars in the night sky, you're seeing other stars in the Milky Way.
Galaxies are thought to begin as small clouds of stars and dust swirling through space. Scientists have been able to segment galaxies into 4 main types that are spiral, elliptical, peculiar, and irregular.
