Dark inflation opens up a gravitational window on the first moments after the Big Bang

Dark matter and dark energy may have driven inflation, the exponential expansion of the universe moments after the Big Bang. A new cosmological model proposed by physicists at the University of Warsaw, which accounts for dark inflation, is the first to outline a precise chronology of the main events during the early history of our universe. The model makes a spectacular prediction—that it should be possible to detect gravitational waves formed just fractions of a second after the creation of spacetime.

Dark energy is an unknown form of energy which is hypothesized to permeate all of space, tending to accelerate the expansion of the universe.

force more mysterious and more powerful than any other has been discovered in the universe. Dark energy has the opposite effect to dark matter, pushing galaxies apart and eventually causing the rest of the universe to disappear beyond sight...

We owe our existence to the triumph of matter over antimatter.

For every billion particles of antimatter there were a billion and one particles of matter and it was the one extra particle in each volume that was enough to build the universe.
