Quick takeaways
Time is unidirectional and we can only move forward into the future, not back into the past.
Black holes reveal the relationship between gravity and time, with time appearing to slow down as an astronaut falls into a black hole from the perspective of an observer far away.
Deep dives
Time as a Unidirectional Force
Time is frustratingly different from space in that it only moves forward. We cannot go back in time, only into the future. This unidirectional nature of time is a significant aspect of our experience.
Black Holes and Time Distortion
Black holes provide insights into the nature of time. As an astronaut falls into a black hole, from the perspective of an observer far away, time appears to slow down for the falling astronaut. This time distortion around black holes sheds light on the relationship between gravity and time.
The Nature of Time and Change
Change is a fundamental aspect of time. Time is measured through the progression of change, and our perception of time is closely tied to the level of change we experience. Time is also associated with the increase of disorder, as events unfold in a more disordered manner, indicating the passage of time.
Time can feel like a subjective experience—different at different points in our lives. It’s also a real, measurable thing. The universe may be too big to fully comprehend, but what we do know could help inform the ways we approach our understanding of ourselves, our purpose, and our time.
Theoretical physicist and black-hole expert Janna Levin explains how the science of time can inspire new thinking and fresh perspectives on a much larger scale.
