Comments by "George Reynolds" (@karhukivi) on "How Gravity Actually Works" video.

The problem with videos questioning the "conventional" view of physics is that they appeal to those with no basic understanding of physics at all! These people will then challenge the physics teacher in school with comments like "gravity is an illusion, not a force" even if they are unable to understand the concept of inverse square. The teacher has to try to undo the garbled version before getting back to the basics.

@siddhantsawant272 There is nothing wrong here, but for beginners at physics, gravity can be considered as a force acting on a mass. Calling it an "acceleration" is confusing for beginners. Telling them that spacetime is "curved" does not help them calculate the period of the orbit of Jupiter! As a geophysicist I have done gravity surveys where we have to make corrections for elevation and latitude as well as the density of the crustal rocks. Even if I understand what is meant by "curved spacetime" it makes no difference to the calculations, it is almost a philosophical concept. Likewise for relativistic calculations, they can be ignored for most purposes. Offering advanced concepts to beginners who don' understand the basics doesn't help, people have to learn to walk before they can run. .

@glorytheman Yes, I agree with you on that. However, it can cause problems even among "experts". For example, a science museum I visited a few years ago had a display of elements and stated that "tantalum was the rarest element". Tantalum may be the rarest "primordial" element in the cosmos, but the element is not rare in the Earth's crust, the abundance is about the same as for arsenic. I pointed this out to the curator, a PhD guy who nevertheless got shitty with me when I said the caption of the exhibit was misleading. There are also videos about the radioactivity of bananas on YT and the comments they attract are evidence of the trouble that advanced concepts can cause when dumbed-down for non-expert viewers.
