Without Gravity Force

Glorimar Torres Pagan

Imagine walking through a park, all appears to be a quiet environment, a warm breeze, and the leaves of the trees moving by the wind, others falling down onto the ground, the birds singing and the children playing throwing the ball. We decided to sit on a bench, which is just below an orange tree, and suddenly "boom", an orange falling over our head. We got up from the bench and wonder ourselves how it may have fallen on me this orange, having a lot of space around me? It is then, where Isaac Newton leaves us the legacy of the law of gravity, where what goes up must come down because gravity is a phenomenon by which all objects with a given mass attract each other.

But what if there is no such force? If gravity did not exist then, neither exist the force of attraction of the masses, so that would not exist our planet. Earth would be a core of rock with a tendency to disintegrate; it would be like a rock floating in a vacuum. The atmosphere would not be there, so there would be no oxygen to breathe. The water would not be forming seas; there would be no plants, no life. In addition to considering the tectonic plates, would have plates being created and destroyed on the surface, generating the grit that tend to flew off the planet. If it would impact a meteorite, it will produce the total evaporation of the planet, or it will accelerate the existing one. Without gravity the final result would be the disappearance of any celestial body that could be formed.

Now, suppose that our scientific development has reached a level where we can breathe oxygen artificially. Still we would have physical changes, our muscles would be weak, and we would be taller and thinner. Similarly, the plants would be enormous and elongated. From the worldly point of view, we would be floating weightless. The universe would be only dust and gas, as gravity was the driving force that joined these masses to form stars. This dust and gas would be dispersed within the limits of the universe, forming a sort of vacuum oval inside and all the mass around it. The universe would be infinite because there would be force to halt the expansion. Moreover, since gravity is a manifestation of the curvature of space, in those areas of the universe, curvature would not exist thereby causing the time be the same anywhere in the universe.

Returning again to imagine us in the park, this time without the presence of gravity, we would be able to float from one location to another; the warm breeze would in this case, threatening, since it can raise an undetermined height. The leaves of the trees would be floating along with the trunk, being a dangerous object. The singing of birds is infinitely dispersed and children lose the ball after they thrown it. Finally, when we can sit on the bench, the orange are not going to fall on our head.
