Futuristic Cosmic Technology: GRADAR could map invisible universe

Researchers claim that a pro­posed future instru­ment called “GRADAR” might use grav­i­ta­tion­al wave reflec­tions to map the invis­i­ble uni­verse in an arti­cle accept­ed to Phys­i­cal Review Letters.

These sig­nals could help astronomers locate dark mat­ter or faint, unusu­al stars and uncov­er infor­ma­tion about their interiors.

The very fab­ric of space and time is being shak­en by grav­i­ty waves, which were first iden­ti­fied in 2015. Grav­i­ta­tion­al waves are used by astronomers to observe dra­mat­ic occur­rences like the merg­er of two black holes, which is extreme­ly chal­leng­ing to observe with sim­ply light. How­ev­er, physi­cists are also aware of the illog­i­cal capac­i­ty of grav­i­ta­tion­al waves to change direction.

Using Ein­stein’s the­o­ry as a guide, they cal­cu­lat­ed the strength of the sig­nal that would come from waves dis­pers­ing with­in a star itself.

This would make it pos­si­ble for researchers to look for large space objects that would oth­er­wise be impos­si­ble to locate, such as dark mat­ter clumps or lone neu­tron stars on the far side of the observ­able uni­verse.

This dis­cov­ery could also be used to map the uni­verse in greater detail and trace the innards of stars.

The lat­ter grav­i­ta­tion­al wave sig­nals, often called “grav­i­ta­tion­al glints,” had always been thought to be too faint to be seen. But due to Ein­stein and his the­o­ry of grav­i­ty, Cleve­land, Ohio’s Case West­ern Reserve Uni­ver­si­ty physi­cists Craig Copi and Glenn Stark­man made a breakthrough.

Can the gravitational wave “radar” be a foundation for futuristic cosmic technology?

Not intel­li­gent yet, but grav­i­ta­tion­al wave “radar” could be devel­oped into an intel­li­gent sys­tem. In order to do so, physi­cists will have to devel­op a sys­tem that can detect small sig­nals from astro­nom­i­cal objects dis­tant from Earth. The sig­nal com­ing from a small object, such as a neu­tron star, would be only about one tril­lionth the inten­si­ty of sun­light. To get enough infor­ma­tion to observe detailed pat­terns, the sig­nal needs to be more than 100 tril­lion times stronger.

The Uni­verse is made up of bil­lions of atoms and galax­ies. Dark mat­ter, or invis­i­ble mat­ter, makes up 68% of the Uni­verse, but we can’t see it. It could be a kind of repul­sive grav­i­ty that dri­ves galax­ies apart, or some­thing unknown.

And the Uni­verse has also been expand­ing since its very cre­ation. Quan­tum mechan­ics explains about a “hun­dred per­cent” of what hap­pens on Earth, the Uni­verse, and even big­ger scale. In such, we need help from Arti­fi­cial Intelligence(AI) to explore the uni­verse further.

For the pur­pose, sci­en­tists could devel­op the grav­i­ta­tion­al wave “radar” (GRADAR) as an AI. “GRADAR AIs” could be cre­at­ed with the help of Machine Learning(ML) tech­niques that are still maturing.

The intel­li­gent GRADAR would be like an intel­li­gent cal­cu­la­tor that col­lects data from a space probe (observ­ing sta­tion). It will process, orga­nize and trans­fer data to an intel­li­gence that can make deci­sions and send it to ground controllers.

Future use of the finding

If sci­en­tists find dark mat­ter, it would be a huge help to astro­physi­cists who are try­ing to under­stand how the Uni­verse began. Dark mat­ter was first hypoth­e­sized in the 1930s by two physi­cists named Fritz Zwicky and Jan Oort.

In addi­tion to this, Grav­i­ta­tion­al wave “radar” could be devel­oped into an arti­fi­cial intel­li­gence. GRADAR AIs could be cre­at­ed with the help of Machine Learning(ML) tech­niques that are still matur­ing. It would be like an intel­li­gent cal­cu­la­tor that col­lects data from a space probe.

Copi said, “It’s a very hard cal­cu­la­tion”. But in the end, we’ve dealt with a lot of sit­u­a­tions like this pre­vi­ous­ly. Con­sid­er the Large Hadron Col­lid­er or even the entire grav­i­ta­tion­al wave detec­tion nar­ra­tive. Once upon a time, it was like­wise believed to be an improb­a­ble scenario.

It will be a sig­nif­i­cant step toward a more thor­ough knowl­edge of the Uni­verse if this research is val­i­dat­ed and con­firmed. We can hope­ful­ly increase our under­stand­ing of the invis­i­ble Uni­verse by fur­ther research and experiments.


Now, detec­tion of grav­i­ta­tion­al waves in the invis­i­ble uni­verse has almost become pos­si­ble. Sci­en­tists hope that GRADAR AIs or fur­ther futur­is­tic cos­mic tech­nol­o­gy would be devel­oped in future. This arti­fi­cial intel­li­gence would be like a space probe or tele­scope. And, it would col­lect data from the uni­verse and send it to an imag­i­nary world!

Our AI could be used for all kinds of pur­pos­es, includ­ing these stud­ies that run on data gath­ered from space probes such as the Voy­ager and Cassi­ni mis­sions, among others.
