Paris, March 30 2021: The recent discovery of “Goldilocks”, a medium-sized black-hole may help answer questions about the formation of the said objects. Black-holes are fascinating objects with strong gravitational pulls and are marked by their ability to even stop light from escaping.
According to past research, black-holes usually fall between 2 size ranges; the stellar-class and the super-massive, with the former being up-to 10x larger than our Sun and the latter which can be up-to billions of times heavier. The newly discovered “Goldilocks” is a rare find in that it falls right in the middle of this mass range (55000x solar mass) according to scientists at the journal Nature Astronomy.
The origins of stellar-classed black-holes are better understood compared to their larger matter-eating counterparts. This is the question scientists like Rachel Webster of the University of Melbourne hope to answer. The “Goldilocks” was observed via a technique of gravitational lensing that analyses gamma-ray bursts resulting from star genesis or collapse, and is likely an ancient relic the likes of which may have acted as seeds for super-massive black-holes.
scientists believe that there are about 40,000 black-holes in the Milky-Way and that they are simply “born that way”, whatever their size, since it is hard for them to accumulate so much mass by themselves over the lifetime of the universe.
The gravitational waves that can bend light, allowing for the detection of black holes were first measured in September 2015.
Albert Einstein’s research theorized that gravitational waves spread through the Universe at the speed of light.
