- I watched this video ( https://youtu.be/rKPv8zApee0 ) and these questions arose:
What is a vacuum if not a space devoid of things?
How did this experiment show there was a vacuum and not merely a different kind of "pressure" (or something else)?
If Evangelista Torricelli truly created a vacuum, then there would be nothing in it, yet you can see through it which means light is obviously still in there (and who knows what else), right?
If there was truly nothing in it, and glass is a highly viscous fluid, and fluids conform to fill empty space, wouldn't the glass have collapsed or deformed to fill that nothingness fairly quickly (for glass) without something holding it in place? Or are the forces holding the glass together stronger than whatever force that creates a vacuum? (What force DOES create a vacuum?)
If it IS empty, wouldn't light behave differently than in a glass filled with air, since there are no particles to distort its path, as it were?
