True. We think; the Oort Cloud is a hypothesis, because so far we are unable to detect small dark objects so far from the Earth. We have never actually detected anything in the Oort Cloud. But long-period comets come from SOMEWHERE, and Jan Oort's idea of a "cloud" of primitive objects makes sense.

No. We cannot alter gravity.
Over time the moon's gravity will drastically alter the Earth's rate of rotation.
Over time the moon's gravity will drastically alter Earth's pole star similarly precession will eventually alter Earth's rate of rotation.
He didn't alter them. He showed that his theory of planetary motion under gravity was consistent with them.
It's the force of gravity which acts on the planets and keeps them in their orbits. Gravity works both ways but the Sun is more massive by far so does not move very much at all. The planets are caused to accelerate towards the Sun by gravity. They move in their orbits with velocities, at any moment, at a tangent to their orbital paths. The result is that they move in a continuous curve around the Sun. If they move slightly closer they speed up, which causes them to move out again, so the orbits are stable. Potential energy and kinetic energy are being exchanged all the time for each planet but the total stays constant.
Yes, boiling does not alter the specific gravity of liquid water.
1. Length of the pendulum 2. acceleration due to gravity at that place
The sun's gravity has a number of effects on the planets. Primarily, the sun's gravity is what sets the orbits of the 9 planets. With one revolution around the sun equaling a solar year (365.25 days on earth). Planets closer to the sun orbit the sun at higher speeds due the sun's gravity being stronger at short distances (Gravity decreases exponentially as distance increases from an object) The sun's gravity also has major tidal effects on the planets. High and low tides cycles on earth are partially a function of differences in the sun's gravity on different portions of the earth. The sun's gravity pulls slightly more on the side of the earth facing the sun, causing fluids to bulge toward that side resulting in a high tide cycle. On Mercury, where the sun's gravity is much stronger, tidal forces are powerful enough to alter solid rock and effect the planets landscape.
In a word, no. At least not that we know of. We're still stuck at the bottom of this gravity well, and we have only limited tools that we can use to get out. None of those tools alter the gravitational constant one bit.
Mass and distance alter gravity Mass is directly proportional to the gravitational force, but distance is inversely proportional. (In other words, greater mass means greater force, and greater distance means less force)
Quantum physics determined that light acts like an electromagnetic wave and a particle at the same time.
Whales alter their bouyancy depending upon the amount of air that they have in their lungs.
