“IT IS AN VACUUM ENERGY OR EMPTY SPACE ENERGY”
MORE EMPTY SPACE ∝ MORE DARK ENERGY
That is simply as the more empty space is created the more dark energy which proves all its points.
From this explanation we can simply approve all the points about dark energy as we can see as the more space is created more dark energy is created and thus this results into expanding of universe and as well increase the speed of expansion of the universe.
We can better understand this through the Friedmann’s equations:-
a = Scale factor
ä = Rate at which expansion is changing
𝜌 (rho) = pressure due to fast moving atoms or radiation
From this equation we can understand how dark energy beautifully fits in the general relativity
WHAT WILL BE ITS RESULT THEN:- From this explanation also indeed the fate of the universe is big rip the universe will keep on expanding till the time there is not light and only darkness in it
