The Pull of Half Life - Guns & Gravity (2020x26)

:

The last of our mini series of science in video games, we turn to one of the classics with full life consequences. One of the most ingenious & famous guns of Half Life is the gravity gun, a weapon that doesn't fire bullets but makes it so you can pull items to Gordon Freeman, or launch them into the stratosphere. But... how would that actually work on a science level? Dr. Erin Macdonald helps break down the science with gravitons, quantum gravitational fields and words that feel more comfortable in a scifi novel than actual science.
