| Re: Satellite said by jstack  :said by PolarBear :The pings can NEVER get better. 22,000 miles will never be any less than 22,000 miles. It's a lot more than that if you think about it. It's 22,300 miles up, another 22,300 down, then it gets routed to the website on ground, and then finally, it goes back up and down to you. It totals about 90,000 miles. Er, internet packets are a form of electromagnetism. EM waves travel at ~186,000 miles per second. This means even if it were 90,000 miles round trip, the packets could traverse the distance in about half a second.
The satellites are 22,000 miles above the equator, which means that if you look at the geometry, it will be further away than that from us folks in North America. Nonetheless, it still would take well less than a second for the round trip. |
