Fragments of energy may be the fundamental building blocks of the universe. The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time.

A radical new theory regarding the origin of the universe suggests that gravitational waves, tiny ripples in spacetime first ...

A fringe new theory suggests that time is the fundamental structure of the physical universe, and space is merely a byproduct. According to Gunther Kletetschka, a geologist — not a physicist, you'll ...

Einstein’s Theory of General Relativity, an immensely important update to Newton's Law of Universal Gravitation, is currently ...

Seeking endorsements for her new book, Chanda Prescod-Weinstein finds herself staring at fundamental questions of space, time ...

Many theories are rock-solid: Scientists have just as much confidence in the theories of relativity, quantum mechanics, evolution, plate tectonics, and thermodynamics as they do in the statement that ...

"It may take decades before we find out what really happens in black holes." Reports of the singularity's demise may have been premature. Earlier this year, new research suggested a potential solution ...

Astronomers used a method once theorized by Albert Einstein to find a mysterious and rare planet on the edge of our galaxy. The planet, AT2021uey b, is a Jupiter-sized gas giant located about 3,200 ...

Astronomers detected in unprecedented detail a collision between two black holes. Their observations confirm predictions made by Albert Einstein and Stephen Hawking.

The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time. The researchers used the theory to answer two problems solved by Einstein.
