How does gravity affect the balance of an egg and muscle strength?

[junk0]

Referring to following video starting at 7:00 minutes, there are something related to gravity, I don't understand,

• Why can egg stand up without falling?
• Why do your muscles stronger in different locations?

Does anyone have any suggestions?
Thanks in advance for any suggestions

Edit, yet another crackpot link deleted.

1.If you take time to balance it, an egg can stand pretty much everywhere.

2.Look up ideomotor effect.

Bottom line is: nothing to do with gravity.

There is, at the "rounder" vertex of an egg, an air-sack. One common trick is to strike the egg sharply enough on the table to crack it slightly and flatten out that air sack (because it is an air sack, no egg leaks out) and let the egg stand on the flattened end.

As Bandersnatch said, this has nothing to do with "gravity". Pretty much everything said in that video is non-sense. I assume you know, of course, that just being at "lattitude 0" means you are on the equator and does NOT mean you are at the "center of the world". The equator goes all the way around the earth. Looks like a tourist trap to me.

That video is garbage. The center of the world? Seriously? The sink trick is nonsense, the egg trick is nonsense.

I would like to address the questions raised in the video regarding gravity. Firstly, the reason why an egg can stand up without falling is due to the center of gravity being located at the bottom of the egg. This allows for stable equilibrium, meaning that any slight disturbance will not cause the egg to tip over. This is also why a spinning top can maintain its balance while spinning.

Regarding the question about muscles being stronger in different locations, this is due to the distribution of muscle fibers in different areas of the body. Some muscles may have a higher concentration of fast-twitch muscle fibers, which are responsible for generating quick, powerful movements. Other muscles may have a higher concentration of slow-twitch muscle fibers, which are responsible for sustained, endurance-based movements. This can vary depending on genetics, exercise habits, and other factors.

It is important to note that while gravity plays a significant role in these phenomena, there are also other factors at play such as anatomy, biology, and physics. I would caution against relying solely on videos or articles from non-scientific sources for understanding complex scientific concepts. It is always best to consult reliable scientific sources or consult with a trained scientist for accurate information. Thank you.
