I wish I was taught Einstein's Special Relativity this way!

Support me   / floatheadphysics   to see how I learn relativity, get sneak peaks, and early video access. We all travel through space time at speed of light. But, what does it really mean? How does it explain the consequences of special relativity - time dilation, length contraction, relativity of simultaneity, and more.
