I've done some reading about different generations of phones, but there's still confusion. :eek:
Is LTE only in 3G phones? Only in 4G phones? what is it?
Will a 4G phone be usable when 5G comes around?
How did they take photos of a black hole when it's really black and invisible? ;)
Why is the last row of the text editor always grayed out? Oops, never mind:D
LTE:

4G will be around for many years. It takes a lot more 5G cell sites to cover the same area, and it will be many years, if ever, before all areas have 5G.
They don't photograph a black hole, they photograph the light outside the event horizon being emitted by the stuff falling into the black hole.
NCIS? never mind
