She could improve her manners.

"Mass attracting mass" is a simplistic description of what appears to happen on the Cavendish experiment. Not a definition, but not wrong either.

Sovereign Being 2y ago

Mass attracting mass was superseded by relativity, which is the warping and bending of space-time. It doesn't work on anything outside of a local scale, which makes it useless for space and cosmology. Relativity has the dark matter and dark energy problem, which they won't solve because it's a totally made up solution which cannot be observed or measured.

The problem with Cavendish is they have to try and isolate the effect to remove any external forces, which on such a scale would be very difficult since magnetism is a significantly stronger force than gravity claims to be.

This was actually covered quite a bit in witsit's stream last night, I've time stamped the discussion for you here - it starts with a discussion about a variant of Cavendish conducted in 2021 in Vienna:

(Outside of that, if you think you could answer any of Austin's questions posed earlier in the stream... I would love to see it (absolutely no sarcasm on my part here).

I really think everyone needs to listen to this stuff. I think flat earthers are wrong, but it’s important to know how convinced people who are wrong can be (whether you think the earth is flat or not). Lots of people just don’t even know how easy it is to be wrong.

When the human brain wants to believe something, no matter how wrong it is, it is somehow right. It's fantastic.

Yup. Sobering

Magnetism has no effect on lead.

The Cavendish experiment stands.

You can see gravity in action with your own eyes thanks to the Cavendish experiment.

I'm trying to find the exact minute on the video.

I guess these are the questions you are talking about?

"Can you provide evidence that the earth orbits the sun?" No, and it doesn't matter. In general relativity all bodies travel in space in a straight line. Therefore the "orbit" is there only at a solar system scale, not locally. That is why you can't "feel it", because you're not going in circles and, in a way, according to GR, the Earth is in fact stationary (except for rotation).

What you **can** prove, is that the moon orbits the Earth and is quite heavy. We can prove that we are being orbited, thanks to gravity.

The contradictions posited in the Newton vs Einstein picture are only apparent. Newtonian physics are OK and used for practical purposes mainly on the surface of Earth. General Relativity is used for planetary scale, stellar scale, galactic scale, etc.

Both approaches are wrong and right. For example, Newton ignored what Einstein discovered about space being flexible and how gravity works. Einstein ignored that the aether (that he refuted) would make a comeback with different names in the future (dark matter, dark energy, quantum physics, etc.) "Aether" is like a placeholder, a wildcard.

There is no perfect explanation of our universe yet. We have approximations to the Truth that are useful in practice. We can make predictions with them. We are grateful for these teachings, but we know that they aren't perfect. They are part of a learning curve for Mankind. Just that.
