When Rush Limbaugh says I'm not a scientist, I'm charmed - I smirk.
When we see the shadow on our images, are we seeing the time 11 minutes ago on Mars? Or are we seeing the time on Mars as observed from Earth now? It's like time travel problems in science fiction. When is now; when was then?
Interpretation
What this quote means
This quote explores the concept of time perception, particularly in relation to distant objects in space, using Mars as an example.
Bill Nye's quote delves into the complexities of understanding time as it relates to distance and observation. When we view images from Mars, we are not seeing them as they are 'now' but rather as they were moments ago, creating a distinction between our perception of time on Earth and the actual sequence of events on Mars. This idea mirrors the intriguing time-related dilemmas often depicted in science fiction, challenging us to think about the nature of 'now' and 'then'.
