“Is Dark Matter and Dark Energy a Fluid?”

Dark Energy

 

“We now think that both dark matter and dark energy can be unified into a fluid which possesses a type of ‘negative gravity’, repelling all other material around them,” said Jamie Farnes from the Oxford University e-Research Center in 2018 about the what is perhaps the great unsolved mystery of  the Universe. “The outcome seems rather beautiful: dark energy and dark matter can be unified into a single substance, with both effects being simply explainable as positive mass matter surfing on a sea of negative masses.”

What if gravity is an illusion, a cosmic side effect of something else going on at deeper levels of reality? The classical theory of gravity is in dire need of new approaches, since it doesn’t combine well with quantum physics. Both theories, crown jewels of 20th century physics, cannot be true at the same time. A Dutch theoretical physicist and string theorist, Erik Verlinde, proposes a starkly different theory – the t
heory of emergent gravity. “For me gravity doesn’t exist,” he says. “We might be standing on the brink of a new scientific revolution that will radically change our views on the very nature of space, time and gravity.”

The Great Unknown –Is Dark Energy New Exotic Matter or an ET Force Field?

Dark Energy

 

Welcome to the biggest mystery in physics: one of the great known unknowns of the universe is the nature of dark energy, an antigravitaional  force field making the universe expand faster. Current theories range from end-of-the universe scenarios to dark energy as the manifestation of advanced intelligent life. It is the proverbial elephant in the “cosmic” room. (more…)

“Truly Incredible” –Our 95% Dark Universe May Be Powered by Unknown Magnetic Forces

Dark Energy

 

“Honestly, our discovery may just be a coincidence. But if it isn’t, it is truly incredible. It would change our understanding of the universe’s composition and why it is expanding at an ever-increasing rate,” says Steen Harle Hansen, an associate professor at the Niels Bohr Institute’s DARK Cosmology Centre, who created a new computer model that replaces dark energy–the mysterious, elusive phenomena that pushes the cosmos to expand so rapidly and which is estimated to account for 70% of the contents of the universe – with a model that combines with dark matter in the form of magnetic forces.

Beyond the Cosmos –“Worlds Utterly Unlike Anything We Can Imagine”

The Multiverse

 

The universe we see –stars, moons, planets, galaxies– is but a small, accidental tip of an infinite cosmic iceberg. During the epoch of inflation, thought to have been triggered by the phase transition that marked the end of the grand unification at approximately 10−36 seconds after the Big Bang, the accelerating expansion of space was far more dramatic than in today’s universe, expanding at an absolutely staggering rate, tearing space asunder. During this period no objects—even two elementary particles—remained close enough to one another for long enough to interact.

Big Bang

 

Something is messing with our universe, and that something is the enduring mystery astronomers have dubbed dark energy –which comprises about two-thirds of the mass and energy in the universe.
