Nasa starts hunting for double giant black holes

NASA has announced that it is improving computer simulations of black holes. The goal is clear: to lay the foundation for the search for these mysterious singularities and to prepare the ground for future research missions.

Strangeness, which is a black hole, is doomed to remain a mystery, but Astrophysicist Scott Noble of the Goddard Space Flight Center has developed computer simulations that can provide a better understanding of these space monsters. In a statement dated 26 May, NASA reported that replicating a double black hole by the Noble Group could lay the foundation for the search for such double systems.

Finding Black Holes: Can't the mission be carried out?

Black holes are extremely difficult to detect and even harder to observe because their luminance is very weak. Dr. Noubl says, "But there is one obstacle to this assertion. The detection of gravitational waves remains irregular. This happens when two black holes with the same centre of rotation eventually merge, most often into a supermassive black hole. As a result, there will be a distortion of space-time, which will be perceived on Earth to an infinite extent.

The first direct detection was made on 11 February 2016 by the joint teams Nasa and CNRS, Ligo and Virgino. At the same time, direct surveillance of black holes is almost impossible. The M87* picture, to be presented in 2019, required several observations during 2017, thanks to the array of the Event Horizon Telescope, followed by several months of image processing and summation to produce a known result today.

In order to overcome these difficulties, there is still a solution to modeling. The knowledge gained over the decades about these invisible giants has allowed the creation of images that reproduce the dynamics of two or three blacks orbiting each other. ", adds Astrophysics Jeremy Schnittman. The image created by Noubl and his colleagues is based on calculations that are almost impossible to do manually, and allows us to model the physical interactions that occur around the horizon of events without depicting it. This method has now determined that the gases that revolve around singularity are glowing in ultraviolet and X-ray rays.

Researchers from the Goddard Space Mission Centre also want to prepare the ground for the future mission "Lisa" scheduled for 2034. A space antenna with a laser interferometer led by ESA, in cooperation with NASA, will be responsible for detecting gravity waves from low orbit. American astrophysicists hope to advance the space probe and gather enough new knowledge to know where to find the desired dual systems.
