For decades, astronomers have relied on Einstein’s theory of relativity to explain the expansion of the universe, assuming ...

Any object lifted above the ground has gravitational potential energy (\(E_{p}\) or GPE). The amount of gravitational potential energy an object has on Earth depends on its: mass; height above the ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding ...

From forces to electricity, energy to gravity, we are going to explore some ... be sure to grab a pen and paper so you can make notes and try out equations throughout the episode.
