TED-Ed: Is time travel possible? - Colin Stuart

The video explores the concept of time travel, highlighting Sergei Krikalev's experience as a cosmonaut who time-traveled into his future due to time dilation. It delves into the historical experiments by Michelson and Morley, leading to Einstein's theory of special relativity. The video explains time dilation through a thought experiment with Jack and Jill, and discusses real-world tests using atomic clocks on planes. It also examines the impact of time dilation on GPS technology and speculates on the future possibilities of time travel, emphasizing the energy challenges involved.

How does the speed of light affect the perception of time for Jack and Jill in the train example?

What experiment was conducted in the 1970s to test the effects of time dilation?

What challenges exist in achieving time travel close to the speed of light?
