Bet you never thought about this?
This debate about the science of speed will make you THINK. The speed of light has been discussed and measured obviously but what about a different way of measuring the universe and its properties? If memory serves correct the speed of light is about 186,000 miles per second. Even the closest star Alpha Centaurai would take us 4.3 years to travel to if going that fast. Think about galaxies billions of light years away wow. It is tough to get one’s mind around that. Without getting into quantum entanglement and really crazy theoretical physics, this question as demonstrated by the ever clever “Vsauce” is something to ponder.
