Dark energy may be vacuum

Researchers at the University of Copenhagen’s Dark Cosmology Centre at the Niels Bohr Institute have brought us one step closer to understanding what the universe is made of. As part of the international collaboration ESSENCE they have observed distant supernovae (exploding stars), some of which emitted the light we now see more than half the age of the universe ago. Using these supernovae they have traced the expansion history of the universe with unprecedented accuracy and sharpened our knowledge of what it might be that is causing the mysterious acceleration of the expansion of the universe.

In modern terms the cosmological constant is viewed as a quantum mechanical phenomenon called the ‘energy of the vacuum’. In other words, the energy of empty space. It is this energy that is causing the universe to accelerate. The new data shows that none of the fancy new theories that have been proposed in the last decade are necessary to explain the acceleration. Rather, vacuum energy is the most likely cause and the expansion history of the universe can be explained by simply adding this constant background of acceleration into the normal theory of gravity.

So how do we exploit all this energy? Nicola Tesla labeled this phenomenon “Aether” and supposedly claimed that he could tap into this mysterious energy.

Until we see an example of this “energy” harnessed, we should consider this and other “Aether” like theories with a jaundiced eye.
