Typically, we will work through the conventional means of observation of astronomy to substances known as luminescent material or baryon substances.

These substances, of course, not necessarily to light, such as low-temperature gas, issued may just microwave; nor is the baryon (protons and neutrons), such as e-mail, but we usually so call to participate in the process of electric and magnetic materials.

Dark matter and dark energy

The universe of luminescent material was only 5 percent less than it was 10 years ago.

The rest of the? if we don't get very solution, can be summarized in one sentence is the dark components and does not participate in electromagnetic effects, at least not directly involved in the electromagnetic field, so the Earth there is technical, we simply "do not see" them. If we want to know a bit more, these dark components into two distinct parts, called dark matter, dark energy of a call.

Einstein's relativity theory tells us that the substance is energy, energy is substance, why here we have to be dark matter and dark energy in separate» because although it is the energy of the dark matter, dark energy is the energy, but they are completely different physical characteristics.

Dark matter in astronomy behaves much like ordinary substances, for example through gravitational attraction, and ordinary matter between gravitation, more "humane". It can be said that there was material somewhere dark matter.

Dark energy is different, they are not special affinity and dark matter in the Universe evenly, where there is space, there is dark energy.

And, there is no dark energy, gravity there repulsion, the repulsion Einstein as early as the 1930s was raised, and later with the astronomical observations, Einstein gave the proposal. Dark energy between repulsion may cause the universe to accelerate the speed continuously. Last century's last three years, cosmologists is doing by discovering the universe to accelerate expansion to infer the universe is full of dark energy and dark matter and dark energy more and the sum of the material. In this way, Einstein accidentally released the Elves can no longer be accepted into the lamp.

A model of harmonious universe

I blog on the universe of all classes will be compared to a harmonious society class.

Dark matter less than the dark energy, more than the substance, only the middle class, material smallest, can be compared to a minority of wealthy classes. More interesting is that cosmologists have will have dark energy and dark matter in the universe model known as harmonious universe model, or consistency model of the universe. Here's a harmonious mean is not to say that the universe to get along with the various constituents of harmony, but this model of the universe and all the astronomical observations, there are no longer apparent contradiction.

Astronomers of the data in the dark universe model seems to be harmonious, and study the universe theorists have unprecedented inconsistencies, disharmony.

I like to say how many cosmologists as the number of dark energy theory, in fact, the number of dark energy may is greater than the number of cosmologists. Therefore, in a variety of cosmology seminar, we often see a variety of theoretical, often see cosmologists. The simplest theory is Einstein's theory of that year, dark energy is a constant that is the unit volume of vacuum energy, never change. However, the easiest is probably the most difficult to explain the theorists, and why vacuum can exist and why vacuum so small — relative the Earth common energy density? why vacuum, however, can also greatly — relative average substance in the universe density?

Dark universe gives me a black eye

Dark Energy's theory are to cosmologists can throw away some of the important in physics.

For example, there is akind of dark energy theory that dark energy of the higher density will change, and will ultimately lead to big rip, tear of galaxies first, then the galaxies to tear, and the solar system was torn, and finally the atoms and elementary particles to tear. This theory, though contrary to some physics "common sense", but some theorists believe that experimental aspects of evidence. Two years ago, I also made their own dark energy theory that dark energy's size by a scale of the universe, this theory is based on the principle of the so-called holographic universe can contain a spherical space to describe, in other words, everything in the universe can be faithfully projected onto one of the "human" boundary. My theory is the market, but there are a lot of opposition. Recently, in Suzhou's dark universe meeting some fellow discussed this theory, it was also questioned. Discuss and question the benefit of research, perhaps, the seminar helped me in the future other theory.

Decide the fate of all hypothetical future experiments.

Currently, theorists of situation can modify a poem to sum up: "dark universe gave me a pair of black eyes, and I use it to find the light. " Naturally, the light is dark universe behind the profound physical laws.
