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

(Image credit: NASA/JPL-Caltech/University of Arizona) Scientists revisiting a mysterious signal from the south pole of Mars have suggested a new potential explanation, and it doesn't bode well for hopes of finding liquid water on the Red Planet.

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.

Astronomers have created a 3D map of a cosmic structure so gigantic that it's almost impossible to even comprehend. The "South Pole Wall" is a flabbergasting 1.4 billion light years across and contains hundreds of thousands of galaxies, Live Science reports.

Astronomers detected mysterious radio waves from the center of the galaxy that vary dramatically and seem to shut off at random. The waves' origin is unknown, so they hint at the existence of a new type of celestial object. The signal doesn't look like the kind that comes from stars, planets, or even dead stars.

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.

U.S. Navy holds patents for enigmatic inventions by the aerospace engineer Dr. Salvatore Pais. He came up with potentially revolutionary technology that can "engineer" reality, devising an ultrafast craft, a fusion reactor and more. While mostly theoretical at this point, the inventions could transform energy, space, and military sectors.

An eminent astrophysicist argues that signs of intelligent extraterrestrial life have appeared in our skies. What's the evidence for his extraordinary claim? On October 19, 2017, a Canadian astronomer named Robert Weryk was reviewing images captured by a telescope known as Pan- STARRS1 when he noticed something strange.
