YouTube Description
as posted by the channelIn this StarTalk “grab bag” episode, Neil deGrasse Tyson and co-host Chuck Nice answer audience questions about relativity, black holes, and the speed of light. They explain that while motion at high speeds causes time dilation, length contraction, and mass increase, objects never become light or reach light speed, and gravitational slingshots cannot propel anything beyond the speed of light—even near a black hole.
