The cosmological constant, which explains how and why the universe is expanding, has been previously described by astrophysicists as “the worst prediction in the history of physics” due to its ...

Scientists have come up with a number of possible explanations. One of the leading concepts is the ‘cosmological constant’ theory, in which the energy of empty space itself causes cosmic acceleration.

Many scientists have also pointed out that the known properties of dark energy are consistent with a cosmological constant, a mathematical Band-Aid that Albert Einstein added to his theory of ...

That's why astronomers have thought that dark energy could be the same thing as Albert Einstein's "cosmological constant," which was an extension of his theory of general relativity. Einstein ...

Astronomers also use gravitational lensing to map dark matter — an invisible substance that makes up about 85% of the universe's mass. They create the maps by observing how much dark matter ...

For decades, scientists have worked to map the universe’s large-scale structure, testing cosmological models and ...

Examples include Einstein's Cosmological Constant, dark energy, the initial proposals of dark matter and inflation. A common feature of "fudge factors" in science is their arbitrariness, and their ...
