The Geometry of Causality | Space Time

This episode is sponsored by Audible. The special theory of relativity tells us that one person’s past may be another’s future. When time is relative, paradoxes threaten. Today, we peer deeper into Einstein’s theory to find that the immutable ordering of cause and effect emerges when we discover the causal geography of spacetime. Recently, we’ve

Quantum Entanglement & Spooky Action at a Distance

In the 1930s, Einstein was displeased with quantum mechanics. He published a speculation experiment, According to this experiment, the point at which an event occurs in the universe can immediately affect another arbitrary event, He calls it “ghostly meta-range effect” and thinks it is ridiculous Because it means breaking the limitation of relativity on the

Speed of Light Thank You!

Dear citizens of the universe, You probably know that light can reach two hundred ninety nine thousand, seven hundred ninety two measly kilometers in a second, but did you also know that physics can now reach over two hundred ninety nine thousand, seven hundred ninety two amazing people in a minute? We’ve broken the speed

How did we Measure the Speed of Light

The speed of light is 299 792 458 meters per second. Exactly. No seriously. By coincidence? No let me explain. The most successful measurement of C was done in 1972 using laser interferometry… laser interferometry. Sounds familiar? Let me help you, LIGO. Laser Interferometer Gravitational-wave Observatory. Yes the technology used to measure the speed of

Misconceptions About the Universe

It has been a time of time in which the universe was expanding so rapidly that its parts were far apart For some of them larger than the speed of light itself this time we live now many people are fascinated From the fact that during the expansion of the universe immediately after Anbthaqh into

Anti-Gravity Wheel?

I am here at the University of Sydney where the mechanical engineering shop has built this incredible piece of apparatus for me. It is a forty pound, that is nineteen kilogram flywheel on the end of a meter long shaft. Can you imagine trying to hold this out horizontally with just one hand at this
