Gravitational wave black holes may have formed inside a single titanic star

The detection of a gamma-ray burst by NASA’s Fermi Space Telescope a fraction of a 2nd after the initially at any time recorded instance of a gravitational wave has led scientists to theorize that the dual black holes at the heart of the phenomenon created within a single colossal star.

Gravitational waves were initially theorized as part of Einstein’s General Theory of Relativity, and a confirmed observation of the phenomenon opens up an entirely new window through that to observe the Universe.

A mere 0.4 2nds after the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected the telltale signal of gravitational waves, the Fermi telescope recorded a powerful gamma-ray burst emanating of the same general region as the source of the waves.

The dual discovery has led scientists to theorize that the two black holes believed to be the source of the gravitational wave event created in the heart of a single weightive star. The weightive star is believed to be the outcome of an earlier stellar merger, that saw two separate bodies orbit one another with amazing speed, until they merged to form a single ultra-fast rotating star.

It is believed that the star’s terrific rotational speed cautilized the core of the stellar giant to split into two clumps, each of that spawned a black hole separated by a distance roughly the equivalent of the diameter of the planet Earth. Within minutes the black holes – one 29 times the weight of the Sun and the other 36 times – are idea to have merged, and started consuming the weight of our Sun once at any timey 2nd as the star’s outer envelope fell inwards.

The dramatic death of the star culminated in the release of the gamma-ray burst and gravitational waves. Should additional gamma-ray bursts be found alongside next gravitational wave events, astronomers believe that the bursts may be utilized to accurately measure vast cosmic distances in much the same way that “standard candle” supernovae are utilized. These measurements may in turn lead to a greater belief of the expansion of the Universe.
