Battery-electric propulsion is considered poorly suited for most full-scale aircraft due to battery weight, positioning hydrogen as a promising alternative with high energy content per pound. The main ...

Why did they form at that time? Astronomers know from observing distant exploding stars that the size of the universe has ...

GENEVA (AP) — Scientists running the world’s largest atom smasher used the $10 billion machine’s accelerator to speed up proton beams for the first time Tuesday, in a step toward experiments about the ...

At the subatomic level, particles interact not only with one another, but with the quantum fields inherent to space, both owing to the presence of charged sources and also to the quantum vacuum of ...

Static electricity works because electrons are strongly attracted to protons, right? But, in atoms, electrons are right there, next to the protons in the nucleus. Why don’t the electrons zip directly ...

Stress is a very real factor in the structure of our universe. Not the kind of stress that students experience when taking a test, but rather the physical stresses that affect everyday objects.

Although tiny, a proton takes up a finite amount of space, enough to fit three quarks, a host of virtual particles, and their associated gluons. The size of a proton’s radius is determined by these ...

GENEVAGENEVA — The world’s largest atom smasher used its accelerator Tuesday to speed up proton beams for the first time as scientists moved ahead in efforts to learn more about the universe. The $10 ...
