Dark Energy Definition:
IT IS NOT WELL UNDERSTOOD AND ITS NATURE AND PROPERTIES ARE STILL A MYSTERY!
Dark energy is a hypothetical form of energy that is thought to exist in order to explain the observed acceleration of the expansion of the universe.
According to the laws of physics, nothing can travel faster than the speed of light in a vacuum. This is known as the speed limit of the universe and it is a fundamental aspect of Einstein’s theory of relativity. The speed of light is the maximum speed at which energy, matter, and information can travel, and it is a fundamental constant of the universe.
There is no evidence to suggest that dark energy, or any other form of energy, can travel faster than light. In fact, the idea that dark energy could travel faster than light conflicts with our current understanding of the laws of physics and would require a fundamental revision of these laws.
