Star speed proves gravity is wrong

The theory

As indicated in the articleThe-paradox-of-gravity-not-respecting-the-energy-conservation-principle/ satellites are subject  to a double  different  force, the gravitational one and the centrifugal one. This implies that the  nearer a satellite is orbiting around the earth,  the faster it has to move  to win the bigger gravitational force and the other way round. To better describe  this idea we have to introduce the concept of angular moment. This is the product of the impulse of the satellite ( I=mxv  where I is the impulse, m is the mass of the satellite and v its speed) and the distance  of the satellite from the Earth, R. Read more

The paradox of gravity not respecting the energy conservation principle

Bernoulli’s theorem

A body orbiting around a planet is in equilibrium between two forces: the centrifugal force and the gravitational force

where Fc is the centrifugal force, Fg is the gravitational force, m1 is the mass of the orbiting body, m2 is the mass of the planet, v is the speed of the body while orbiting, r is the distance of the body from the center of the planet, G is the gravitational constant

111, 333, 666, and many other curious digits. What are Demlo numbers?

The Earth map used in the UN flag: 33 sectors

A grid, probabl
y representing parallels and meridians, divides the Earth in 33 sectors. Another special number is 11, 33 being a multiple of it. You probably wonder what  it means and what relation have these numbers with the Earth.

33 appears immediately as a particular number, being a palindrome. Moreover 3×3=9;  33×3=99… another palindromic digit I like is the number 12321. If you sum all digits, you’ll obtain 9 again. Read more
