Why you can’t use quantum entanglement for faster than light communication

Albert Einstein, with his theory of special relativity, established that the speed of light is the absolute speed limit of the universe.  A rocket ship attempting to accelerate to the speed of light encounters some well known effects: time dilation, mass increase, and length contraction.  The closer to the speed of light it gets, the … Continue reading Why you can’t use quantum entanglement for faster than light communication

Why faster than light travel is inevitably also time travel

I've always loved space opera, but when I was growing up, as I learned more about science, I discovered that a lot of the tropes in space opera are problematic.  Space operas, to tell adventure stories among the stars, often have to make compromises.  One of the earliest and most pervasive is FTL (faster than … Continue reading Why faster than light travel is inevitably also time travel
