Event horizons , a issue of oecumenical relativity , freestanding black holes from the rest of the universe . If you make a singularity , an issue apparent horizon will look . But what if the supermassive objects at the center of galaxies are not black hole ?
This mesmerism has been studied in several alternative theory of somberness , so researchers from the University of Texas at Austin and Harvard decided to put them to the mental test . They front at what properties a monumental , not - tumble object would have and get through the conclusion that it would have a toilsome outside .
In a newspaper publisher published in theMonthly Notices of the Royal Astronomical Society , the research worker determined what would befall if a star were to slam into this severe surface . They decided that the star would be destroyed and stellar material would spread across the surface .
" Our motive is not so much to build that there is a hard surface , but to labour the boundary of cognition and encounter concrete grounds that really , there is an consequence view around black holes , " senior writer Professor Pawan Kumar said in astatement .
He added : " Our whole pointedness here is to turn this idea of an event skyline into an experimental science , and find out if event skyline really do exist or not . "
This theoretical background allow for a clear experimental forecasting . If general relativity is ill-timed and there are toilsome surfaces where event horizons should be , then we should be able to see the leading signaling . The squad used the Pan - STARRS telescope in Hawaii over a period of 3.5 years , looking for these objects .
" We estimated the rate of star fall onto supermassive smuggled holes , " lead writer Wenbin Lu added . " Nearly every wandflower has one . We only considered the most massive one , which weigh about 100 million solar great deal or more . There are about a million of them within a few billion idle - geezerhood of Earth . "
The team approximate that they should have had at least 10 sensing , but they saw none . Event horizons do seem to exist and oecumenical Einstein’s theory of relativity appear to have survived another test .
" Our work implies that some , and perhaps all , blackened holes have outcome horizons and that material really does disappear from the evident universe when pulled into these alien objects , as we ’ve expected for decades , " co - author Ramesh Narayan of Harvard conclude .
There is still plenty that we ca n’t excuse about gravitational force , so general relativity theory will have to be amended in time , but for now the hypothesis is safe .
