revised Dependency of buoyancy on volume and mass of submerged object
formatting, use "object" in place of "mass" where it seems more appropriate to remove ambiguity about meaning of "mass"

comment How precise can current technologies measure the mass of an object?
I vote the mosquito-sandgrain-gigameter be adopted as a new standard unit of force. so we can just say the force is 0.6 Floris ;-)

It is not a question of opinion but of evidence produced from 1887 until 2016 (129 years of research)

If "Space is the boundless three-dimensional extent in which objects and events have relative position and direction" - doesn't it follow that your question is "not even wrong"?

Space. What level of answer do you seek? What dictionary definitions have you read and what part of those needs clarification?

comment Why water's temperature is less than air?
@AbtaheeSalekeen: You really need to quantify "after sometimes" and "increases". For example make readings of temperature of both air and water in Celsius every 60 seconds for two hours and keep notes of time and temperature. Quantify the volume of the bowl. Measure the volume of the water and/or weigh the bowl before and after to estimate the losses due to evaporation. Etc. What are the numbers? What are possible sources of error? Are people opening & shutting doors/windows or occasionally operating machinery nearby?

comment Is the CHAMP missile capable of doing what they say it does?
Reported in 2009, tested in 2012 against typical commercial PCs (actually rather elderly ones with CRT displays) in a typical office building - not against EMP-hardened targets.

comment effect of opening the barrier between a tube with one side pressurized and the other side a vacuum
I did a few sums and concluded a Saturn V produces 50 times as much initial thrust as this vacuum tube. As the water reaches the top, a 5 km Saturn-V sized tube would be lifting 375,000,000 Kg of water. The speed of the column as it neared the surface might be less than many people might think.
