Scientists Have Started Searching For Other Dimensions And Parallel Universes

Scientists have finally set out to search for parallel universes and other dimensions. The revolutionary mission will not only study gravitational waves and their potential influence in parallel universes and other dimensions but will offer scientists unprecedented scientific data that will help develop future missions.

“Extra dimensions have been discussed for a long time from different points of view,” said Emilian Dudas at the École Polytechnique in France in an interview with New Scientist. “Gravitational waves could be a new twist on looking for extra dimensions.”


The existence of other dimensions has always nurtured the imagination of scientists and lovers of science fiction. Now, the European Space Agency (ESA) has approved a mission that will initiate the hunt for gravitational waves in space, and with it the opportunity to finally prove the existence of extra dimensions, and/or parallel universes.

Gravitational waves—those small undulations in the space-time tissue of the Universe, believed to be caused by the movement of very massive cosmic objects were first discovered in 2015.

And since gravity is very likely to be able to spread through all dimensions that may exist, these waves have become a very promising way to detect any dimensions beyond those we know exist.

With the aim of looking for more of these waves in space, the ESA has given its Laser Interferometer Space Antenna mission (LISA) the green light for a 2034 launch, after decades of development and delays.

Speaking in an interview to New Scientist, Professor Mark McCaughrean, ESA’s senior adviser for science & exploration said: “I think there’s a mixture of super-excitement and ‘at last’.”

“We’re finally over the starting line – it’s great.”

The mission will be composed of THREE main, identical satellites which will be separated by a staggering 2.5 million kilometers, spread out in a triangular formation and will follow the orbit of our planet around the sun.

After entering a stable orbit, the satellites will fire powerful lasers between one another, searching for ripples in space-time caused by the existence of gravitational waves.


As noted by New Scientist, “…in order to detect these minuscule changes, on scales less than a trillionth of a meter, LISA will have to shrug off cosmic rays and the particles and light from the sun. The LISA Pathfinder mission, a solo probe launched in December 2015, proved that this sensitivity was possible and galvanized researchers working to realize the full LISA mission.”

With such high sensitivity, one challenge will be sifting through colossal amounts of data to find the signals with the most scientific promise.

“That’s the amazing thing – we can hear everything in the universe with gravitational waves,” said McCaughrean.

The LISA satellites will analyze how the gravitational waves warp space by detecting any changes in the distances the lasers travel.

Clever right?

According to experts, gravitational waves are created by cosmic objects which have a very strong gravity—like a pair of black holes merging.

But not only will scientists have unprecedented data regarding black holes, add ripples in space-time, it is a unique opportunity to search for parallel universes.

Recently, experts have offered evidence that parallel universes exist thanks to the so-called ‘Cold Spot’. The ‘anomaly’ which measures a staggering 1.8 BILLION light years across has left experts baffled.

Based on numerous measurements of the background radiation of our universe, experts found the anomaly to be COLDER than its surroundings by 0.00015 degrees Celsius.

According to experts, the humongous anomaly cannot be explained by missing matter, which means that it requires other explanations, with one being EVIDENCE of the existence of other ‘parallel’ universes.

According to Professor Tom Shanks, an astronomer at Durham University and coauthor of the study: We can’t entirely rule out that the Spot is caused by an unlikely fluctuation explained by the standard model of particle physics. But if that isn’t the answer, then there are more exotic explanations.

But definite evidence is still ‘missing’.

This is why scientists are getting excited about the study of gravitational waves.

In an interview with New Scientist, Gustavo Lucena Gomez, who is leading a study into extra dimensions at the Max Planck Institute for Gravitational Physics in Potsdam, Germany, said: “If there are extra dimensions in the universe, then gravitational waves can walk along any dimension, even the extra dimensions.”

As noted by experts, gravity is much weaker than any OTHER fundamental forces, making experts question whether this may be the result of GRAVITY escaping into other dimensions.

German experts calculated how another dimension would affect gravitational waves, coming across two weird effects: extra waves at high frequencies and a change in how gravitational waves are able to stretch space.

Experts found something totally unexpected. They discovered that as gravitational waves advance through extra dimensions, they should generate a ‘tower’ of additional gravitational waves with higher frequencies. Regrettably, we are unable to spot frequencies that high and experts are focusing on searching for lower frequency gravitational waves.

Dr. Lucena Gomez added: “If extra dimensions are in our universe, this would stretch or shrink space-time in a different way that standard gravitational waves would never do.”
