minus-squarethere1snospoon@ttrpg.networklinkfedilinkEnglisharrow-up2arrow-down1·2 years agoBut doesn’t relativity explicitly state that c is the speed of light in a vacuum, and travelling through other mediums explicitly changes and is explained by relativity? I am 100% a layman and do not know the answer.
