WebRichard Feynman discusses how Newton was able to explain gravity, the tides, and how we first calculated the speed of light. The full video can be seen here... Why do we need three time dimensions? To understand, we have to talk about some math. “[D]espite our common perception, time and space are strikingly similar according to relativity, and mathematically the only difference between them is the minus sign somewhere in the equations,” Dragan explains. That’s … See more There’s another interesting aspect to this research, because Dragan’s team wants to show that even at superluminal speeds, physics shows symmetry. “The idea … See more So, this paper isn’t about travelingat warp speed, but instead an analysis of physics to show how we can bring two very different physics branches together. Why is … See more
