In some interpretations of quantum mechanics, such as the Many-Worlds interpretation or the Pilot Wave Theory, parallel universes may form every time a subatomic particle goes through any interaction.
A wild theory suggests that consciousness may explain quantum mechanics, by forcing the subatomic particles to choose one concrete outcome.
According to quantum mechanics, the physics theory that describes the zoo of subatomic particles, all matter can be described as both particles and waves. But is it real?
What lurks at the center of a black hole? Studying the space-time ripples from black hole collisions could reveal an answer.
Our 13 billion-year-old galaxy has gone through many growing pains — usually to the detriment of its smaller neighbors.
Most matter in the universe cannot be seen — but its influence on the largest structures in space can.
Short answer: We don't really know how the universe was created, though most astrophysicists believe it started with the Big Bang.
The Standard Model is the modern physical understanding of three of the four forces of nature: electromagnetism, the strong nuclear force and the weak nuclear force.
A team of physicists has found that the remnant of a neutron star merger observed in 2019 has just the right mass to be a strange hypothetical quark star.
Dark energy could be caused by pressure from giant voids of nothingness that may be flinging the universe apart.
Albert Einstein's famous equation E = m^2 connects energy to mass via the speed of light. Find out why E = m^2.
If aliens exist, they do exist, they might be hanging out on Dyson spheres circling the husks of sunlike stars called white dwarfs.
Humans aren't just making Earth warmer, they are making the climate chaotic, a stark new study suggests.
Reference Pulsars are the ultradense cores of gigantic stars that emit beams of radio waves in regular pulses, like cosmic lighthouses.
Reference It's quite a big question and a lot is still unknown about the universe, but we'll tell you everything that we do know, from how the universe was created, how old it is and what it's even made of.
An ultraprecise measurement of the mass of the W boson may diverge from the Standard Model, a long-reigning framework that governs the strange world of quantum physics.
Reference From the beginning of the universe to the present day, it's one of the few things we regard as regular and unchanging. But is it really so constant? We take a look at the physics of time.
A seemingly intractable black hole paradox first proposed by physicist Stephen Hawking could finally be resolved — by wormholes through space-time.
REFERENCE The northern lights appear in the sky when charged particles from the sun slam into molecules in the atmosphere, releasing energy in the form of colorful lights.
