There are a lot of different aspects and areas, which are unanswered by nature, and this is the basic reason for a lot of research, which has been happening in the world today. Because of this curiosity, a lot of scientists and astronomers have come on to take up a lot of interest and effort in to solving these black boxes in science. An important question is, what is dark energy? If you look in to the field of astronomy, the black box is around the nature, composition and the size of the universe. You can see a lot of research in this era in this area and speculative analysis from the very beginning. In the area of astronomy, the greatest revelation from the scientists and the astronomers is the proving of the fact that the universe is expanding on a steady rate. There were a number of questions on the establishment of this fact. Out of all these questions, the major question was around the less amount of matter, which goes on to create the universe as a whole. As this matter, content in the universe is low and it is a known fact that the geometry of the universe is linear as a whole, the expansion of the universe can be attributed to something called as dark matter or dark energy.
A lot of scientists and astronomers are asking this question since long. The question is – what is dark energy. It is this dark energy, which is the cause of the acceleration in the expansion of the universe. However, there is yet another revelation around this dark matter or dark energy, which is quite baffling to know. This is around the fact that the effect of this dark matter or dark energy goes on to vary as well.
Apart from this, the exact composition of the universe as argued and proposed by the promoters and a supporter of this theory is extremely though provoking and interesting. There are different DE instruments available. These include Dave Smith Mopho and Doepfer’s Dark Energy. According to research, the dark energy goes on to contribute to as much as seventy percent of entire universe. Twenty-five percent of the universe can attribute to the dark matter, while every other matter, which we know, composing our earth and other elements is only about five percent. What this goes on to establish is that empty space is not empty after all- it is composed of something we now know as dark energy or dark matter – as proposed by Einstein.
