The Concept of Space and How it Relates to Our Universe
How do we know that we’re in Space? We can’t breath there, but there are many things we do know about space. First of all, it is a vacuum, which means it’s made of small, discrete bits. Then, we know that Space is a continuum, and that we’re part of a large continuum. This article will explain the concept of space and how it relates to our universe.
It’s a vacuum
If you’ve ever been in space, you’ve probably wondered if it’s a true vacuum. There is no atmosphere in outer space, and so there is no air to fill it. But is this really the case? Is gravity real in space? You may be surprised to learn that space is actually a vacuum. And the answer is actually quite interesting. This is not to say that gravity doesn’t exist, though.
It’s made of tiny discrete bits of space
The modern concept of discrete nature derived from Ancient Greek atomism, which argued that nature is composed of indivisible individuals and discrete bits of space. It was thought that nature was not static, but was a composite of atomic matter in motion. Because of this, it is possible to observe and measure all objects and phenomena using only discrete measurements. Unlike classical physics, however, this new concept is more complex.
It’s a continuum
The idea of a space-time continuum may sound like something that only scientists can explain in science fiction, but this is not the case. Einstein, a brilliant scientist, first put forward the concept in 1905, when he developed the general and special theories of relativity, which are the basic concepts of quantum physics. Specifically, they looked at the laws of physics surrounding the speed of light.
It’s a sheet of rubber
A floppy sheet of rubber, if made of enough mass, can represent gravity waves. A bowling ball tossed in space would cause a disturbance, but the ripples propagate in finite time. In contrast, Newtonian gravity predicts that a reaction will occur immediately. The rubber sheet analogy impedes further understanding of gravitational fields. While it can illustrate the idea that space-time is curved, it fails to address the implications.
It’s an unbounded continuum
If the world is an unbounded continuum, then everything exists in the same state and time. However, if you look at a state composed of discrete spectra, they are all equally bounded. If, however, the world is an unbounded continuum, then the entire state has an average energy that is much larger than the energy of the discrete spectra. Similarly, if a state consists of unbounded, finite-length, and infinite-length paths, then it is an unbounded continuum.
It has curves
In two-dimensional geometry, the surface of the earth is a sphere. This curved surface is a classic example of curved space. Despite its complexity, this surface is still a surface. In Einstein’s theories of relativity, all matter in the universe acts gravitationally on the stage of space-time. Here are some examples of curved spaces. These spaces have the potential to change shape as light changes it.
