If universe is expanding without a limit and dark and vacuum energy are created as it expands…?
That's really interesting. Do scientists have any idea why dark energy is causing the expansion of the universe to accelerate?
Actually, scientists are still trying to figure that out. One theory is that dark energy is actually a cosmological constant, which means it is a property of space that is pushing the universe apart. Another theory is that dark energy is related to an unknown force that is causing the acceleration.
