Yeah- you make good points. I think what I was upset about was that we started with a given (they obviously work in space) and then half the class argued they didn’t for a while.
A better question would have been “how can they work since space has no air in space?” which leads to great q & a I think.
Make sure you’re not mixing up MBps and Mbps. Internet speed is almost always measured in megabits (Mbps) not megaBytes (MBps), the former being 1/8 of the equivalent megabytes per second.
55 megaBYTES per second is just fine, that’s a full HD movie download in about 3 minutes. 55 megaBITS would be about 24 minutes for the same thing. Would that matter to you? No idea. But if you’re currently at 100, everything would take about twice as long as before the switch regardless.
