Scientists Across The Globe Celebrate The Mysterious Element Holds Universe Together:

This Halloween,Scientists Celebrate In A Different Way:

Dark matter and dark energy holds universe together

Witches, goblins and the quest to solve the mystery of dark matter.

This Halloween, Scientists across the world are going to celebrate the mysterious element they believe holds the universe all together.

People who are interested in the dark and the unseen will soon have a new reason to celebrate. They will be able to honour, on Halloween, the hunt for dark matter, the mysterious, unseen, invisible material that is thought to permeate space and hold galaxies all together.

Across the US,Britain and Europe, talks, demonstrations and parties highlighting this massive astronomical search will be held on 31st October 2018, which has been remarked 'Dark Matter Day' by scientists who are seeking to discover the make up of this elusive material.

“I don’t think you could pick a better date to celebrate a hunt for something that is as ephemeral and mysterious as dark matter,” said physicist Chamkaur Ghag, of University College London. “We can see its effects, but cannot detect it directly. It is the ultimate in ghostly 
In fact, after 20 years of searching and the investment of tens of millions of pounds,not a single Wimp has ever been detected, either at Cern or in underground detectors built in Britain, Europe and the US.

“So far we have found absolutely nothing that fits the bill,” admitted Professor Ofer Lahav, of University College London. “Nevertheless I would say 99% of physicists would still say they believe Wimps exist.”

This point was backed by Ghag. “It is frustrating not to have found dark matter after all this effort. The trouble is that we have absolutely no idea how big Wimps are. They could be the size of a hydrogen atom or they could be absolutely tiny by subatomic standards. Or they could come in lots of different sizes. That affects the kind of instruments we need to detect them.”

Nor was the absence of corroborating evidence for dark matter unusual, Lahav stressed. In the 19th century astronomers discovered major aberrations in the orbit of Uranus but solved the puzzle when they realized another planet must be disturbing it. That led to the discovery of Neptune. Then disturbances in the orbit of Mercury were discovered. This time the explanation had to wait until Einstein published his general theory of relativity in the 20th century.

“So a final understanding of the nature of dark matter could be a relatively straightforward one, as in the case of Neptune, or something that is revolutionary, like the theory of relativity,” added Lahav.

In this latter category, some scientists now argue that it is the nature of gravity that is not understood properly and that the odd rotation of galaxies could be explained by re-evaluating Newtonian physics. Dark matter simply does not exist, say these scientific apostates. Most researchers disagree, however.
