The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the baryon class are reported from the LHCb experiment located at the Large ...

The universe, with its vastness and complexity, continues to confound scientists. Recently, the detection of anomalous particles has pointed towards even more mysteries waiting to be unravelled. These ...

Primordial black holes are hypothetical black holes thought to have formed moments after the Big Bang. Because they supposedly formed about 14 billion years ago, and black holes are thought to ...

As the name suggests, particle accelerators involve accelerating subatomic particles to incredibly high speeds and smashing ...

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

How old is the universe? Learn more about the age of the Universe, from it's explosive beginnings to how we on Earth can measure its age. Roughly 14 billion years ago, a tiny pinpoint of extreme heat ...

The universe's matter-antimatter asymmetry, where matter significantly outweighs antimatter despite their theoretically equal creation at the Big Bang, remains a major unsolved problem in physics.

Roughly 14 billion years ago, a tiny pinpoint of extreme heat and density erupted in a grand explosion, leading to the creation of between 100 billion and 2 trillion galaxies, one of them being our ...

Forget about turtles; for all practical purposes, it’s really particles all the way down. Consider the seemingly simple matter of their size, the very thing that makes them so alien. We’re typically ...
