The European Space Agency (ESA) has approved a 2034 space project to scan for gravitational waves in the vastness of the Universe. The program, called, LISA, can open a road for testing ripples in the space-time fabric, which can attest for the existence of parallel universes. Something which until recently was mere phantasy or hypothesis.
Hunt for Gravitational Waves to Commence in 2034
Although the necessary technology is not yet available, by 2034 the LISA program can provide a route to scan for ripples in the space-time fabric.
Gustavo Lucena Gomez, the lead scientist of the study into extra dimensions at the Max Planck Institute for Gravitational Physics, Potsdam, Germany, said that
“If there are extra dimensions in the universe, then gravitational waves can walk along any dimension, even the extra dimensions”.
The argument is that gravity is weaker than the other fundamental forces. And one theory would be that it is so because it is escaping into an extra dimension. The German team of researchers is trying to calculate just how exactly would an extra dimension affect gravitational waves. Until now, there are only two variants. The first: extra waves travel at high frequencies; the second: there is a change in how gravitational waves stretch space.
Researchers found that, while gravitational waves move through an extra dimension, these waves generate a “tower” of extra gravitational waves with higher frequencies.
For the time being, observatories do not have the means to scan and hunt for gravitational waves at that high of a frequency. Instead, they are focusing on the lower frequency of gravitational waves.
While there is serious doubt in spotting the gravitational wave towers, detecting the change in the way gravitational waves stretch space might be easier, say researchers. Of course, an extra dimension would add another way for gravitational waves to stretch space. This mode is called “breathing mode”. The analogy is with the lung: as lungs expand during breathing, gravitational waves make space expand and contract.
Scientists are now happy that, in the not so distant future, they will be able to scan and hunt for gravitational waves, hoping that they might find that the existence of parallel universes is not just an idea or concept. If this were to be true, it would completely change the way in which we understand the concept of “reality”.
