Earth is about 40,000 km in circumference, so there's about a factor of four left to win on that particular hop.
- kevhito 10y agoSpeed of light within a fiber optic cable is about c/1.5, so closer to a factor of 3. Throw in various continents that need to avoided, I'd guess it would be closer to factor of 2 in practice.
