When speaking of our universe, it's often said that "matter tells spacetime how to curve, and curved spacetime tells matter how to move." This is the essence of Albert Einstein's famous general theory ...

A team of researchers led by the University of Warwick has developed the first unified framework for detecting "spacetime fluctuations"—tiny, random distortions in the fabric of spacetime that appear ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...

Me: I am thinking about holography, but no one else seems to have thoughts like mine. I think it is self-evident if you look at the inflation diagram, but such inspiration does not seem to appear. I ...

A proposed experiment could shed light on the unknown interplay of quantum theory and general relativity. Quantum theory in curved spacetime can be theoretically understood beyond the limit at which ...

Few ideas in modern science have reshaped our understanding of reality more profoundly than space-time: the interwoven fabric of space and time at the heart of Albert Einstein’s theory of relativity.

Most of today’s leading theoretical physicists have a shared perspective about what the next revolution in physics will look like. They think reconciling Albert Einstein’s general theory of relativity ...

The quantum revolution in physics -- whose 100th anniversary we have just celebrated -- taught us that at the most basic level the world is bizarrely different than it seems. But, we appear to only ...

Mind-bending materials called quasicrystals have an orderly structure, but without a regularly repeating pattern. They’ve been found in meteorites and the debris from the first atomic bomb test.
