Recently had a zoom chat with my cousin in US (I am in India). Still blown away by the fact that millions of bits of video and sound data can travel across half the planet in seconds. How is it possible?
In: Technology
The distance (along the surface) between the US and India is about 13,500 km. Your data will travel close to the speed of light at around 300,000 km/sec. In an idealized sense, this means it will take roughly 50 ms (about a 1/20 of a second) for the data to travel.
Obviously there is some pre- and post- processing of data sent that must be done and the data doesn’t take a direct route, but all these things generally are much smaller factors than the physical travel.
