Either that, or he lied about it.
In the above diagram, what is the source of gravitational interaction at focus 2?
Kepler’s 1st law is empirical, that is to say, is based on direct observation. Direct observation tells us that the planets appear to have elliptical orbits around the sun.
An ellipse is formed when an object is attracted to two sources of gravity. They are called Focus 1 and Focus 2.The plural is foci.
However, the explanation of Kepler’s 1st law doesn’t include a second source of gravity. The scientific explanation of why planetary orbits are elliptical is because they are ellipses.
Does that sound like circular reasoning to you?
According to science, Focus 1 and focus 2 are just the geometric points of the ellipse. They’re just there because the orbit is elliptical. There are more elaborate explanations about the curvature of space and gravity wells, but they are entirely fictitious. So even though Kepler’s law is empirical, the commonly accepted explanation for it is not. It is one of the major leaps of faith made in the dominant paradigm of science which it conveniently doesn’t mention.
Science = faith.
Science is abusing your trust.
Even though direct observation tells us that the planets appear to have elliptical orbits around the sun, science didn’t attempt to honestly account for why. Rather, it took off on its headlong rush to concoct a rationale for godless existence. This was a golden opportunity for the patriarchs of science to be able to hammer the last nails into the coffin of Geocentricity and they seized it. This is an example of intellectual abuse of the highest magnitude: confounding a simple issue in the obscurity of scientific jargon in order to hide and conceal truth.
Why are planetary orbits elliptical? they aren’t, they just appear to be. However, since science doesn’t have to prove anything to be able to make the cosmos work, it is safe to make up anything at all.
Do you want to know the answer?
Okay, I’ll tell you…
The source of gravity at focus 2 is the Earth.
The Earth-Sun radial distance is basically constant (give or take a minute amount of play). The other planets have elliptical orbits because they orbit the Earth-Sun system. The seasons are not the result of annual fluctuation in the earth-sun distance.
Mercury and Venus have elliptical orbits which have one focus inside the orbit (the Sun) and one focus outside (the Earth). The outer planets have elliptical orbits with both foci within them.
With this arrangement it is impossible to tell if Earth orbits the Sun or vice versa.
Now you will see that your empirical formulas aren’t empirical (because you have to guess missing information) and that a geocentric system accounts for all observations.
It is interesting that Tycho Brahe provided all the accurate data necessary to be able to give an honest explanation of Kepler’s 1st Law, but he was drowned out by the desire of sinful men to finally pin down the rationale for godless existence. Notice that in the heliocentric part of the .GIF they didn’t even both with ellipses. That is how cavalier the scientific community can be. They figure that saying the words is enough, most people are too stupid to understand anyway.
