All stars are the result of a balance of forces: the force of ... WebFeb 14, 2024 · Close up, that gravity crunches atoms together. And squeezing two atoms into one creates a powerful burst of energy, as humans witnessed firsthand when they built their own fusion bombs. Stars spend most of their lives repetitively compressing two hydrogen atoms into a single helium atom – plus a lot of energy, which is released as …
WebAccording to general relativity, gravity can be described as a distortion in the structure of spacetime. Objects like planets and even light follow the straightest possible path within that structure, but the stronger the gravity, the more curved the paths become. ...
