I know I'm jumping in late on these, but...
Yes to both of these.
Yes, but without the "(at least in today’s terms)" qualifier. Speed is, by definition, distance travelled per unit time.Do each of you agree that speed, (at least in today’s terms) is determined by distance/time?
Even if not suspended in mid-air, the directions I could choose to go in are endless (not spherical, that is a meaningless description for "direction")... but actually going in most of them would involve tunnelling or fighting gravity.Do each of you agree that if you are suspended in mid-air, the directions you could choose to go in are endless or spherical?
I disagree. Miles, feet, inches, km, cm and mm are different units describing the same concept, linear distance. The distance described by a mile can also be described as a certain number of inches, but inches do not "exist within" a mile, any more than volts or ohms "exist within" an electrical conductor.Do each of you agree in every mile or in every 1.609344 kilometers, exists 63,360 inches, 5,280 feet, 160,934.4 centimeters and 1,609,344 millimeters?
Barring further clarification, I disagree. "Everything", being all-inclusive, is meaningless.Do you agree that everything in the universe can be described within a mathematical equation?
