Even the existence of dark energy

Dark energy hypothesis seems to be the observation of the accelerating expansion of the universe today one of the most popular in the interpretation of the results. But now scientists about the 114mm carbon seamless steel pipe china suppliers nature of dark energy and the localization of research, suspected of being no progress. It's very clear they know nothing to the object of research so far, is that right?

Implicit in this argument, a very powerful question: since astronomers always show their study progress is slow, dark energy is always complaining about the research object of the mysterious, isn't even the existence of dark energy, they are not sure?My answer is pretty sure, they can confirm the existence of this kind of material. Let's go back the long radius butt weld pipe elbow discovery process of dark energy.

Since the big bang theory is widely recognized and receiving in the 1960 s, scientists have been trying to calculate, a reduction factor of digital, it describes the process of the expansion of the universe because internal material gradually slow down the rate of attracted to each other. Reduction factor is so important, have the following several reasons. carbon steel concentric reducer First, it tells people the observable universe total quality, as well as its ultimate fate, gradually slowing expansion to rest, and then the whole process in reverse. Second, it is a key factor to determine the age of the universe. Because it records since the big bang the universe's expansion rate of change.

And to calculate the reduction rate, scientists will need to present the expansion of the universe, and it compares the performance of conceptions in the distant past. Fortunately, because light has a fixed speed and become the natural measuring scale: observe a galaxy 1 million light-years from earth, for the human, actually see is that it is like 1 million years ago. Billions and billions of galaxies, thousands of light-years away, the same is true of.

In the 1990 s, three scientists according to this principle, this paper proposes a new method of computing the universe reduction factor: observe a very far away from earth, a supernova in the outbreak. This method not only let them 11 years was awarded the Nobel Prize in physics in the next century, more bring the dark energy.
In their experiment, with the observation data, calculate the reduction factor also gradually become smaller, until zero - represents a no quality of the universe. Three scientists do not believe in it so far, and sure enough, then reduction factor becomes smaller than zero. This represents the end of the universe to slow down, began the accelerated motion. And, more importantly, to accelerate the power of not gravity, but also the power of an unknown. Three people decided to call it - the dark energy.
In 1998, when the first paper on observing distant supernovae was published, many scientists say. But with the passage of time, consistency and repeatability of the method and results have been verified. Cosmic background radiation, the evolution of clusters, such as research, and illustrates its correctness.So, now is not what dark energy mystery, it's more like a copy of our observable universe behavior specification.

Like all the speech ended with Thanksgiving. After answer the above questions, explore the magazine pointed out that the answers for these important proposition, is not, but from all over the world to dive and toil of astronomers and physicists, of course, want to thank all of our telescopes and countless hard the top equipment apparatus.
Finally, and most importantly, we must understand that for the origin of the universe and annihilation, as there are too many have hit areas and we have to know the truth, many now regarded as the something of the truth, may soon be upset by new knowledge - that was the crystallization of centuries, is now in a few book in a hurry, some become truth, some as errata - but whatever it is, in science to explore the historical long river, the scientists who are uplifting and clarification of the human psyche, cognition about the universe as a whole structure and operational mechanism, will never be as time flows and weaken the charm.
