Jericho,
You claim that you do not believe in gravity, but you believe in electromagnetic forces, correct? Neither of these forces contradict Christian teaching, in fact they can both point toward a Creator. The formula for calculating the force of gravity is F = G*M1*M2/r^2. Where G is a measured constant, M1 and M2 are the masses of the objects in question, and r is the distance between the two objects. (This is why gravity can hold the moon in place but we can jump, the moon weights about 7.3*10^22 kg (or 730000000000000000000000 kg) and we weight about 60 kg, so the force of gravity on the moon is that many times stronger than the force on us!) The gravity constant G is about 6.674*10^-11 m^3 kg^-1 s^-1. (don't worry if you don't know what that means, its small number). Meanwhile the electomagnetic force is calculated by F = k * Q1 *Q2 / r^2, and the constant k is 9 * 10^9 ( a large number). Both of these constants, K and G, are extremely precise and fine tuned. If gravity were any stronger, starts would collapse into black holes, and if it were weaker they would just be collections of dust. If the electromagnetic force constant was stronger then electrons in atoms would enter the nucleus of atoms and chaos would follow. If it were weaker, electrons would exit the electron clouds and nothing good would happen. (I'm no nuclear physicist ok!). The fact that both of these constants are exactly what was necessary for life to exist points toward a planned universe. You should look this up its very interesting!
You said that things fall when you remove something underneath them, but why do they fall? anything you drop will fall if there is empty space underneath it, and they are all attracted to the center of mass of Earth. you could perhaps attribute this to the electromagnetic force, but that would mean that all objects would need to be charged the such an extent that the force could produce that kind of acceleration.If an apple were charge to that extent it would rip itself apart! (lets say the earth is negative and the apple is positive because opposite charges attract. Positive charges repel other positive charges, so the apple would repel itself and same goes for the earth.) Ionic compounds wouldn't be able to exist because there wouldn't be enough electrons!
You said gravity is used to explain planetary evolution, which is true. Of course, not all Christians believe that planetary evolution is false (a whole other discussion), but lets say you're in the camp that Christianity is only true if planetary evolution didn't happen. (AKA God made everything as it is instantly). With this logic, if you know God is real, then planetary evolution has to be false. However, this doesn't prove that gravity has to be false, and I will explain how. Lets say you come home and the oven is on and the there is a fresh cake on the counter. You're not sure how either of these things got there, but you assume that someone used the oven to bake the cake. Of course, the cake could have just appeared there, but that doesn't mean that the oven isn't turned on, because you can still observe that. Another example, you walk into a room and read a clock that says 3:30. it is ticking and will soon hit 3:31. Most people think that since it is ticking now it was ticking at 3:29 and just turned, but could it not have been set just prior to you walking in the door? If it was, this does not mean that the clock has to set every minute, perhaps the person who set the clock also wound it up so that it will keep ticking in the future.
You also mentioned a quote of Tesla. Just because a famous person said something doesn't make it true. Just look at ancient scientist thinking that the sun revolved around the earth.
One final point (for the Christians reading this). God made us as rational creatures. with rational thought comes science. He knew we would explore the world that he has made, so he made laws of nature for us to discover. He would not make anything that would disprove himself because he is a just God, therefore all science points toward God.
If any of my science or logic is wrong please let me know I don't want to lead people astray.
