Geocentricism

My opponent forgot one teensy-weeny thingTHE SPEED OF LIGHT IS THE SAME FOR ALL OBSERVERSHopefully I don't need to prove this since it's arguably the fundmental postulate for a majority of modern theories.Yes, it is true that the speed of light slows donw in certain mediums relative to others, but in the Michelson Morley expirement, the light is always travelling through air, making that point irrelevant. Why there arrive at the same time is a much more "fun" question and was brought into light by Einstein's theories of Relativity. In his theories, Einstein states that space and time are intertwined into a thing called "space-time". This essentially allows for the speed of light to remain constant for all observers. For example, say you are travelling at 0.99c, since D = RT --> T = D/R. Now imagine a light clock on this ship that looks a little something like this: Where the first light clock is what the observer's light clock would look like to the observer and the second one is what the spaceship's lightclock would look like to the observerObviously D increases since the light has to travel a much longer path; however, time is here to save the day. Time would seem to slow down in the spaceship relative to an observer, and vice versa since the spaceship would see the observer travelling at .99c in the opposite direction. It's obviously much mroe complicated than that, but I don't think my opponent will want to challenge Einstein. However, for the Michelson-Morley expirement, not only does time slow down but space can contract by the equation Ask any physict about this problem, and they will always tell you how the length contraction * the expected time delay = 1. Let me quickily clarify that if you walk 10 miles at v = 5 km/hr, that is not the same as walk on a conveyor belt for 5 miles that boosts your speed of 1 mph and then walking the other for 5 miles (slowing you down by 1 mph) for obvious reasons... (the second scenario is slower)You can calculate how much slower it would be via the equation 1/(1-(v/V)^2)where V is the velocity (5 mph)and v is the velocity of the conveyor belt (1 mph) Now let's look at a relavant example, let's say the Earth was rotating at .5c (obviously hypothetical).Using the above equation (plugging in c for V and the rotational velocity of the Earth for v) you get that the Michelson-Morley expirement should find that the time should be 1.1547 times slower for the second light beam. However, if you calculate for the Lorentz contraction, you get a value of 86.6% (meaning, that the length of the trip for the second light beam would be 86.6% of that of the first light beam's)Multiplying these two... gets you... wait for it... 1! (When you use exact values, I gave approximations obviously).As you can see, Einstein's theory of Relativity clearly predicts the Michelson-Morley expirement, even though it wasn't specifically meant for this expirement. It works perfectly fine for a rotating Earth and doesn't require a stationary Earth.Now... I want my opponent to present a model that can A.) Explain how the Sun would rotate around the Earth, even though the Sun's mass is hundreds of thousands times that of Earth's... unless my opponent would care to disprove both Einstein's and Newton's theories of gravity (which haven't failed a single test so far)B.) Explain the retrograde motion of Mars to be EXACTLY what we observeC.) Explain the phases of VenusD.) How day and night and the seasons workE.) The planet's moonsF.) How we are able to detect exoplanets via Doppler shift and Transit method if the star goes around the planet(s)Oh, and show how evidence for each part of the model... don't simply say "It's obvious", you're the one who called me Stupid :).Enjoy
