The European research centre announced its spoof discovery with pictures showing its scientists using The Force in everyday life.
It was one of many April Fools jokes seen on websites around the world.
Others included a selfie shoe, driverless pizza delivery and thought-powered web search.
"The Force is what gives a particle physicist his powers,"  said Cern scientist Ben Kenobi of the University of Mos Eisley, Tatooine in a press release.
Many scientists at the centre were already using The Force, said the release, to communicate over long distances, influence minds and for "lifting heavy things out of swamps".
Microsoft used the background image for its main Bing search page to tout its April Fools joke in which it claimed the search system could read palms and minds to ensure people got the results they really wanted.
Anyone could try thought-powered search by putting their right hand on a screen where the Bing homepage indicated.
"The innovative new search function intelligently analyses the electrical signals transmitted through the hand to calculate the relevant search term," said the software firm.
Many other firms and sites produced spoof announcements and products for 1 April.
Smartphone maker Samsung produced a spoof page for a Blade edge version of its Galaxy smartphone that, it claimed, was designed for cooks. The limited edition handset incorporates a diamond-edged blade so the phone can also be used to chop food when it is not being used for calls, texts, or browsing the web.
HTC joined in with fake product pages for the Re-Sok - the "world's first truly smart sock". The technology-enhanced footwear is engineered with GPS so pairs of socks can easily find each other and have an automatic hole warning system to alert owners when their intelligent footwear is running thin.
For its April Fools parody, Motorola went to the trouble of making a lavish video showing two craftsmen producing selfie-sticks out of wood and leather.
New York-based footwear maker Miz Mooz joined in and produced a pair of shoes that have smartphone docking ports in each toe so each one can be used to take selfies.
Other parodies included cab-calling firm Hailo introducing piggy-back rides around cities; Domino's pizza introducing a driverless pizza delivery system using autonomous scooters; BMW making the ultimate rugby mouth guard and Sony making a wearable add-on for the PlayStation so players can take part in games when they are swimming.

Crews were called to a building site in Bloomery Circle, Llanwern, at 21:15 BST on Wednesday.
The blaze burned for more than 10 hours before it was extinguished.

A Gwent Police spokesman said: "Officers are investigating the circumstances surrounding the fire... which is believed to have been deliberately set."

Officials in the city of Novosibirsk ruled that Parnas, the main opposition coalition, had failed to collect enough valid signatures to take part.
Russian opposition leader Alexei Navalny called the move a "blow to the democratic freedom of Russians".
The regional ballot is seen by Russia's opposition as a key test in the run-up to next year's parliamentary vote.
The three hunger strikers were detained by police and fined for staging a protest.
They and other activists in the Siberian city had spent weeks collecting the thousands of signatures required to register for election.
But the election commission in Novosibirsk - Russia's third largest city - found faults with more than 1,000 of the 11,000 signatures they submitted.
The activists insist they were valid, and said the authorities used out-of-date databases to check them.
In one case, a woman's signature was ruled out because her middle name came up in records as Timurovich, a man's name, instead of Timurovna.
The three - Leonid Volkov, Sergey Boyko and Yegor Savin - have said they will eat nothing and drink only water until their case is reviewed.
Mr Navalny warned that the "surreal" action could be replicated in other elections, both regional and national. He is a fierce critic of President Vladimir Putin, accusing the government of large-scale corruption.
"There is a political order not to let the opposition take part in elections," he told Moscow Echo radio station.
The Force - the mysterious energy field used by the Jedi in Star Wars - has been discovered by researchers at the Cern laboratory.
