Timeline of fundamental physics discoveries
This timeline lists significant discoveries in physics and the laws of nature, including experimental discoveries, theoretical proposals that were confirmed experimentally, and theories that have significantly influenced current thinking in modern physics. Such discoveries are often a multi-step, multi-person process. Multiple discovery sometimes occurs when multiple research groups discover the same phenomenon at about the same time, and scientific priority is often disputed. The listings below include some of the most significant people and ideas by date of publication or experiment.

gollark: Do those exist? Can you *guarantee* such properties in a cave without heating or anything?
gollark: I don't like caves, they're generally small, cold and wet.
gollark: I don't really think "can make you wear masks in an emergency situation" is much of a problematic power though, really.
gollark: no.
gollark: That is not a high bar.
