We have observed the acceleration of the expansion of the universe. To explain this phenomenon, we usually introduce the dark energy (DE) which has a negative pressure or we need to modify the Einstein's equation to produce a term which is equivalent to the dark energy. Are there other ...
Célérier, M.N.: Is the apparent acceleration of the Universe expansion driven by a dark energy-like component or by inhomogeneities? astro-ph/0612222 (2006)C´el´erier, M.N.: Is the apparent acceleration of the Universe expansion driven by a dark energy-like component or by ...

I think it's common sense to understand that if you stretch a rubber band with your fingers, you're going to feel a force trying to counteract the expansion of the rubber band. It's just as logical to understand that if galaxies out in the universe move away from one another, the for...

New Atlas, 24 Oct. 2024But research that began in the 1990s has shown that something sparked anaccelerationof the universe’s expansion about 6 billion years ago, and the cause remains a mystery.— Ashley Strickland,CNN, 23 Oct. 2024See all Example Sentences foracceleration ...
Recent observations of near supernova show that the acceleration expansion of Universe decreases. This phenomenon is called the transient acceleration. In the second part of work we consider the 3-component Universe composed of a scalar field, interacting with the dark matter on the agegraphic dark...
