When you send a text to someone as I understand it they are transmitted to the other persons phone via a satellite. When the other phone is off they don't recieve this till later when it is switched on. Where is this text in the mean time? This may seem incredibly stupid but I could't figure it out.
I ask this because it took thousands of years to develop the most simple tools, machines once lasted hundreds of years then decades, and now it seems like my phone is out of date every month.
will we have everything, or will it be things are out of date every day, or will the growth reach a peak and stop at some point?
