A Day Without Yesterday 🤯 - Origin Of Universe - George Lameitre | w/ Professor Brian Cox

Appealing to the new quantum theory of matter, Lemaître argued that the physical universe was initially a single particle—the “primeval atom” as he called it—which disintegrated in an explosion, giving rise to space and time and the expansion of the universe that continues to this day.

What is the cosmological constant?
In modern cosmology it is the leading candidate for dark energy, the cause of the acceleration of the expansion of the universe. In the context of cosmology the cosmological constant is a homogeneous energy density that causes the expansion of the universe to accelerate.
