A dramatic glimpse of the aftermath of a collision between two exoplanets is giving scientists a view at what can happen when planets crash into each other. A similar event in our own solar system may have formed the moon.

In physics, antimatter is simply the "opposite" of matter. Antimatter particles have the same mass as their counterparts but with other properties flipped; for example, protons in matter have a positive charge while antiprotons ...

Researchers at the Massachusetts Institute of Technology (MIT) have recently developed a metric that can be used to capture the space of collider events based on the earth mover's distance (EMD), a measure used to evaluate ...
When two protons collide, they release pyrotechnic jets of particles, the details of which can tell scientists something about the nature of physics and the fundamental forces that govern the universe.

A few millionths of a second after the Big Bang, the universe was so dense and hot that the quarks and gluons that make up protons, neutrons and other hadrons existed freely in what is known as the quark–gluon plasma. The ...

In particle physics, a jet is a shower of collimated particles generated by a highly energetic quark or gluon. In a lead-lead collision, jets must traverse through quark gluon plasma, altering their energy, track and consistency.

Collisions of lead nuclei take place under extreme physical conditions. Their course can be described using a model which assumes that the transforming, extremely hot matter—the quark-gluon plasma—flows in the form of ...
