Gravity is a ubiquitous part of our daily lives — whether we’re being tragically brought to our knees after tripping on the rug or gleefully jumping from a swing’s apex. But despite how common the ...

Physicists show knotted cosmic strings may have dominated the early universe before collapsing to create matter—a theory ...

Japanese physicists have revived Kelvin’s old idea of cosmic knots, showing how these tangled fields might explain why matter ...

If you’re superstitious, a black cat in your path is bad luck, even if you keep your distance. Likewise, in quantum physics, particles can feel the influence of magnetic fields that they never come ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. This article is more than 4 years old. The gravitational field on Earth ...

In quantum mechanics, charged particles like electrons can be sensitive to the effects of electromagnetic fields, even when placed in a region where both the electric and the magnetic fields are zero.

Just as ocean waves shape our shores, ripples in space-time may have once set the Universe on an evolutionary path that led to the cosmos as we see it today. A new theory suggests gravitational waves ...
