New research from theoretical physicists at the Perimeter Institute proposes that our universe may have emerged from a black hole in a higher-dimensional universe. The big bang poses a big question: if it was indeed the cataclysm that blasted our universe into existence 13.7 billion years ago, wh

The Big Bang Hypothesis - which states the universe has been expanding since it began 14 billion years ago in a hot and dense state - is contradicted by the new James Webb Space Telescope images, writes Eric Lerner.

KB: We asked ourselves, "what obliquity, what misalignment would Planet Nine induce in the solar system?" because it must induce some. We know that Planet Nine's orbit in inclined. As a result, when Planet Nine torques the rest of the solar system, the two sort of act as two precessing tops.

A subatomic particle has been found to switch between matter and antimatter, according to Oxford physicists analyzing data from the Large Hadron Collider. It turns out that an unfathomably tiny weight difference between two particles could have saved the universe from annihilation soon after it...

Much remains unknown to scientists about the era immediately following the big bang, when the universe was hot, dense, and devoid of spiral galaxies like our modern Milky Way. Consequently, it's difficult to pin down when the first complex galaxies were born. But we're beginning to close this cosmic gap of empirical darkness.
