What The IF the SPEED OF LIGHT were much much much much much s... l... o... w... e... rrrrrrrrrrrr? Like WTiF it were only 4 MPH, so that when you went walking, you were already rocketing along, step by measly human step, at HALF the speed of light? What if you RODE A BIKE and tried to pedal faster, faster, faster, could you push your way past the pokey 4 mph speed of light??? When he was a spry young 16 years old, Albert EINSTEIN imagined himself doing all kinds of crazy races with his bike against light beams. And boy did his imagination tell us some AMAZING and BIZARRE things about what we would experience in this (relatively!) magical bicycle ride down our street. Strap on your helmet, hop on your bike, and get ready to race a light beam. You can do it, all you have to do is shout, What The IF, and hit that play button!
