In what is being called a 'huge milestone', scientists at CERN has been able to observe antimatter particles, the existence of which was predicted by Albert Einstein in his theory of relativity more than hundred years ago. Antimatter is the twin of visible matter that is all around us. The announcement of observation of antimatter was made on Wednesday (September 27).

The scientists have observed 'falling' antimatter. The observation definitively rules out that gravity repels antimatter upwards. If the previously held notion were to be true, it would have upended the vertu fundamental understanding of the Universe.

It is believed that the Big Bang, the unimaginably huge explosion that formed the entire Universe 13.8 billion years ago, formed equal amount of matter and antimatter.

Everything we see or feel is made of Matter while Antimatter is the equal but opposite counterpart.

However there is virtually no antimatter in the universe, which prompted one of the greatest mysteries of physics: what happened to all the antimatter?

"Half the universe is missing," said Jeffrey Hangst, a member of CERN's ALPHA collaboration in Geneva which conducted the new experiment.&nbsp;

"In principle, we could build a universe -- everything that we know about -- with only antimatter, and it would work in exactly the same way," he told AFP.

Physicists believe that matter and antimatter almost entirely destroyed each other after the Big Bang.

Presently, matter makes up for just five per cent of the Universe while rest is made up of dark matter and dark energy. Antimatter meanwhile vanished.

Scientists had been trying to find answer to a key question for years. It was, whether gravity caused antimatter the same way as normal matter. It was held that gravity repels antimatter.

So, to connect the concept with the famous story of Newton's Apple, if the apple would have been made up of antimatter, would it have shot up into the sky? If gravity indeed repelled antimatter, it may have meant that creation of impossibilities such as perpetual motion machine was possible

But the experiment at CERN, carried out by team of scientists, yielded different result.

The team constructed a 25-centimetre-long (10-inch) bottle placed on its end, with magnets at the top and bottom.&nbsp;

Late last year, the scientists placed around 100 very cold antihydrogen atoms into this "magnetic trap" called ALPHA-g.

As they turned down the strength of both magnets, the antihydrogen particles -- which were bouncing around at 100 metres a second -- were able to escape out from either end of the bottle.

It was then simply counted how much antimatter was annihilated at each end of the bottle.&nbsp;

It was found that around 80 per cent of the antihydrogen went out of the bottom, which is a similar rate to how regular bouncing hydrogen atoms would behave if they were in the bottle.&nbsp;

This result, published in the journal Nature, shows that gravity causes antimatter to fall downwards, as predicted by Einstein's 1915 theory of relativity.

Einstein proven right again, scientists find antimatter ‘falling’, not defying gravity

Albert Einstein continue to fascinate us with his brilliance. The equality of inertial and gravitational mass central to Einstein’s general theory of relativity has been confirmed at unprecedented sensitivities by the MICROSCOPE satellite.

Albert Einstein's mind-bending theory of relativity proven again

Albert Einstein's&nbsp;earliest notes on the theory of relativity sold for a record $13.17 million at an auction.

The manuscript was co-authored by Swiss physicist Michele Besso who was a friend of Einstein. It was written between 1913 and 1914.

The auction at Christie's in Paris set a record for Einstein's work whose earlier "God letter" had sold for $2.8 million three years ago and another letter had fetched 1.56 million in 2017.

Einstein's another letter describing the E=mc² equation was sold for 1 million euros at another auction in the United States in May.

The 54-page document provides a glimpse into Einstein's mind as he set about defining the general theory of relativity.

Christie's thanked&nbsp;Besso for preserving the document while calling it a "miracle". Reports say the auction house had estimated the handwritten notes would fetch $2.25-3.38 million, however, it shot way past the mark. The identity of the buyer has not been revealed.

Christie's said &nbsp;Besso and Einstein had together "attacked one of the problems that had been troubling the scientific community for decades - the anomaly of the planet Mercury's orbit."&nbsp;

Einstein put his thoughts on paper which was preserved by his colleague and friend Besso. Christie's said Einstein's work during this period is extremely rare while adding that it is an "extraordinary witness to Einstein's work".
