I see gravity as a mechanical reaction, rather than some kind of mystical force.

This action is only momentary, just (A) Is a set of balance scales that are non-magnetic.

(a-1) This half is set over the (B) piece of iron

(a-2)This half is set out over free space

(B) Is a 1ft.x1ft.x1ft. piece of Iron at a temp as [Cold] as you can make it

© Is a high temp insulator

(D) Is a 1ft.x1ft.x 2ft piece of Iron at a temp as [Hot] as you make it

(E) Is a stand to hold the experiment.

(F) Is a glass pan filled with sand or any non-magnetic[ Mass] like pea

gravel.Once this is set up remove © the high temp insulator

(a-1) will lose gravitational pull on it making it rise and

(a-2) to lower and at the same time causing the non-magnetic

mass in (F) to be attracted to bottom of (D) thus we have man made gravity fields.

until the thermal differences equalizes.



What is being demonstrated is hot air rising. The cold iron above gets heated, causing the cold air around it to also heat by thermal induction and rising (as hot air does) pushing against the balance above the cold piece of iron as it heats up. Once it heats up to room temperature (or higher as the metal below simultaneously cools as it transfers heat into the cold lump above and both head towards room temperature) the effect ceases - proving nothing new. I would imagine this experiment would not work nearly so well (at all) in a vacuum. It makes an interesting Rube Goldberg device, though.

I'm not sure what to make of the original post that started this thread... I agree that gravity is most likely a field, but I can make heads nor tails of the post itself.

Curious... but what kind of numbers are we talking about here?

Mass in (F) will be gravitationally attracted to (D) anyway, but are you saying that (F) will actually levitate and be pulled upward by a force greater than g?

How hot is as [Hot] as you can make it and how cold is as [Cold] as you can make it?

Do you have photographic or video evidence of it? Thanks.




Well the hottest that I had was 1854° F and the coldest that I was able to get

with my equipment was 17°F.

And yes I did have video but I lost it and all my best equipment in hurricane Ike

few years back.
