Understanding Space-Time and Relativity

The video explores the concept of space-time, emphasizing its inseparability. It discusses how photons interact with space-time, particularly focusing on the implications of relativity and time dilation. As objects approach the speed of light, time slows down, and for photons, time effectively stops, making their journey from the Big Bang to the present instantaneous from their perspective.

What is the fundamental concept of space-time as discussed in the video?

• Space and time are separate entities.

• Space and time are interconnected.

• Space is more important than time.

• Time is more important than space.

How does a photon from the Big Bang reach us according to the video?

• It does not travel at all.

• It travels through both space and time.

• It travels through time only.

• It travels through space only.

What happens to time as you move faster, according to the video?

• Time reverses.

• Time remains constant.

• Time slows down.

• Time speeds up.

What is the effect of approaching the speed of light on time?

• Time speeds up.

• Time stops.

• Time remains constant.

• Time reverses.

For a photon, how is time experienced from emission to absorption?

• As a long journey.

• As an instantaneous event.

• As a series of events.

• As a delayed process.
