After you've watched the film. Take some tyime and concider this: The universe is expanding, hence, the negative pressure is building up, since the universe is basically made out of vacuume. What happens if you throw something into a vacuume? It grows, and the gravitation forces grow accordingly within the material you throw in.

60 million years ago, the dinosaurs suddenly died out. Why? Because of what I just said. Since the negative pressure of the universe around us makes the Earth bigger, and no longer could the huge dinosaurs live under their own weight. A T-Rex would have collapsed today, just by it's own weight. Hey, even the elefants suffer today

Negative pressure is not building up because the universe is expanding. The universe is expanding because of something like positive pressure within it, this pressure is a function of the cosmological constant, and is caused by dark energy. The universe is being pushed apart by a positive force within it.

As you go higher and higher the pressure decreases, as it approaches the extremely low pressure of space.

Gravity is related to size, not weight. Newton even explained it long ago. Density change won't change the weight of anything, but if density decrease, mass will change, however, this relative change in mass, will not change the weight of the atoms in that body, but the size will change. Heat something, and it defies gravity, weather is based on this, due to density change, however, the total gravity on Earth will rise, due to how the atmosphere is actually growing when you heat it up, and the positive pressure in the same atmosphere rises and the Earth itself expands.

That isn't right. Look at any basic physics text, or even just google any of this stuff. At this point you're way off.
Mass determines weight, weight is force due to gravity(thats why you weigh less on the moon). Mass is a measure of energy density by e=mc^2. Energy density is what causes the deformation of spacetime which is responsible for gravitational effects. This stuff is at the foundation of modern physics.
mass (from Ancient Greek: μᾶζα) commonly refers to any of three properties of matter, which have been shown experimentally to be equivalent: inertial mass, active gravitational mass and passive gravitational mass. In everyday usage, mass is often taken to mean weight, but in scientific use, they refer to different properties.

Didn't you just say that the Universe was expanding since there was such high pressure up there? The pressure of space is infact negative, and the expansion of the universe is not due to pressure, but something called accelerating and moving dark matter, making the overall pressure of space to be continuously decreasing. Niob anyone? Since you're such an expert, tell us all what happens when mass explodes. Tell us about the winds and pressures involved, and explain it, don't trench it by drowning us in sunreliable sources.

Well, apparently not. It may conflict governing science, and the body of science is one which is very fond of orthodoxy and is often reactionary in relation to new ideas and thougts. or like William James said back in the 19th century:
"A new idea is first condemned as ridiculous and then dismissed as trivial, until finally, it becomes what everybody knows."
When it comes to the reverse version, dissmissing "aknowledged facts" are almost impossible to go through with. For more than a millennium, the Church proved this.

Galileo was a genius ahead of his time. He made sure his science was consistent with data.
