Mathematical equations have shaped our understanding of the universe, and these nine have played a key role in changing the world.

"As yet, nobody has managed to understand what gives rise to this strange phenomenon, and explaining dark energy remains one of the most formidable challenges of modern science." ...

Some attribute it to a cosmological constant, a fixed energy density filling space. Others suggest a more dynamic form of dark energy or even fundamental modifications to Einstein’s theory of ...

This is called the “heat death” of the Universe, but you can think of it instead as the death of heat. There will be no more differences in temperature anywhere, which means thermodynamics shuts down, ...

Einstein first toyed with this idea of a repulsive form of gravity in space, calling it the cosmological constant. Even more mysteriously, the current expansion rate appears to be different than ...

Fundamental physics, dark energy, matter, and universe expansion will be explored during a free lecture offered to high ...
