The Rocket & String Paradox
This video is about Bell's Spaceship Paradox of Special Relativity, wherein a pair of rockets (or spacecraft) connected by a weak thread accelerate with uniform acceleration, maintaining the same separation, and the question is: does the...

Length Contraction and Time Dilation | Special Relativity Ch. 5
This video is chapter 5 in my series on special relativity, and it covers how things that are moving (that is, moving relative to an inertial reference frame) at different speeds appear to be shorter in length... and longer in...

Impossible Muons
This video is about how terrestrial muons are part of our experimental proof of time dilation, length contraction, and special relativity in general.

Spacetime
In this video Paul Andersen explains how the dimensions of space and time are combined in relativistic mechanics. Gravity and velocity can affect both space and time according to Albert Einstein's Special Law of Relativity.

Special Relativity: Crash Course Physics
So we've all heard of relativity, right? But... what is relativity? And how does it relate to light? And motion? In this episode of Crash Course Physics, Shini talks to us about perspective, observation, and how relativity is REALLY weird!

What You Would Experience Near the Speed of Light
All the light that we see are electromagnetic waves. All different wavelengths are equivalent, except that waves of higher frequencies are more energetic. The speed of all these EM waves, however, is the...

Special Relativity Part 3: Length Contraction
Time dilation was pretty weird, huh? Well we aren't done yet! Time is relative, and so is space! Different observers measure different lengths for objects and journeys. Weird stuff!

Einstein's Relativity (3): The Famous Equation E=mc2
Time dilates, contracts, is relative, and can travel? Yes, all these components of Einstein's Theory of Relativity have been validated in the scientific community through extensive experimentation. What have they learned? Discover...
