Professionally I am a Radiology guy.
One of the darn few new products that still employ a vacuum tube. X-ray generators, radar, and microwave ovens are the only common items I can think of, I'm sure there are others.

High voltage required, 45,000 - 120,000 volts on the anode for human diagnostics.
I'm a careful sort, that kind of voltage can make you a pile of ashes. I'm old, not bold.
186,282 miles per second in a vacuum, the ballpark speed of light. Classic physics. Einstein.

That may or may not be the "real" speed limit of the universe, stay tuned!
