In our daily environment, we encounter matter in three different states: solid, liquid, and gas. In space, a fourth state of matter exists: the plasma state. Plasma is like a gas, with individual ...

Black hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of ...

In that paper, Maxwell laid out a long list of calculations (based on existing physics rather than observation ... a collection of rocks or ice or other space stuff, all held together in a ...

the standard model of particle physics has also overtaken experiment by successfully predicting what is later observed. Theories with extra dimensions of space could follow suit, but results 1 ...

Space agencies have systems in place to spot, track, and forecast the future orbits of potentially hazardous asteroids.
