GPS location apps on a smartphone can be very handy when mapping a travel route or finding nearby events. But how does your smartphone know where you are? Wilton L. Virgo explains how the answer lies 12, 000 miles over your head, in an orbiting satellite that keeps time to the beat of an atomic clock powered by quantum mechanics. Lesson by Wilton L. Virgo

Im having a hard time beliveing every cell phone on earth is directly connected to a sattelite. Cellphones are connected with cell phone towers on earth. Cellphones can broadcast to something 12 000 miles away? The sattelite is broadcasting at the speed of. . light? Directly to your cellphone? Doesnt it take a lot of power to get a radio signal to travel far? Then why would there be a delay while communicating with the ISS for instance? Is the cellphone simultaniously connected to the sattelite and the cellphone tower?

I know why the video has so few views. It's because people are like;
70% of them = it's cause I've turned on the location on my phone duh.
30% of them = it has to do something with satellites.
They are missing the whole thing

I guess at some point, Humans need to part away into separate groups of those who believe in science and those who keep mocking it.
I mean, we already hv group of bunch of people who believe in different kind of religions.

If you include that you are on earth and in the range you the current cellphone tower you are connected to (and sometimes the wifi networks you can see) you can narrow it down to 2 or 3 satlights.

So the energy transition between atoms is induced by the probe laser? Am I correct in assuming that the animation at 1: 37 happens 9 billion times a second? Please help.

Imagine every human ever born has brains like this and working hard together for the human evolution! Maybe we'd be watching a ted ed video from Mars or Moon by now.

All it takes. Billions of your tax dollars to track your every move to a tee. We know so much about science but how its used is often questionable.

This video doesn't explain the main problem: my smartphone doesn't have atomic clock, so the time difference couldn't be measured that simple.

GPS was originally designed to enable the United States to drop a nuclear weapon down any smokestack in Russia. Still could.
