I have 1 last question before 2023 is over - I already know what the speed of light is [ 299,792,458 metres per second (approximately 300,000 kilometres per second; 186,000 miles per second; 671 million miles per hour)], but what is the speed of dark?
@duglop dark matter; dark energy; dark speed: it’s still a mystery, man. Still a mystery. Say “hi” to Steven Wright for me….
