What is Space-Time?
Space-Time is the four-dimensional continuum combining three dimensions of space and one of time, forming the stage where the universe unfolds.
The background video illustrates how massive objects, like the Sun, warp the fabric of space-time. Smaller objects, like Earth, follow curved paths due to this distortion, which we perceive as gravity. This visualization helps explain concepts introduced by Einstein's theory of general relativity.
Concepts
- Relativity: Demonstrates how time and space are interconnected.
- Gravitational Waves: Ripples in space-time caused by massive cosmic events.
- Black Holes: Extreme warping of space-time where gravity reigns supreme.
Applications
Space-time concepts are foundational for technologies like GPS, as well as understanding astrophysical phenomena like black holes and wormholes.
Fun Facts
Time passes slower near massive objects due to gravitational time dilation—an effect you experience near Earth’s surface compared to a spacecraft.
