This is , without a incertitude , the cool manner to make a black jam . It ’s what happen when physic overdoses on poesy and mumble to itself in an back street . It ’s when light inverts itself .
Most astronomy texts give a spry overview of what goes into the making of a black hole . A star collapses , and so much matter gets draw in down into so belittled an area that it basically pull itself into a breaker point . That point has , technically , no volume , but it has infinite compactness . Venture too close to a pitch-black hole and all that mass , squished into multitudinous tightness , will attract you in so forcefully that not even getting speed to the f number of light will get you out again . And all because there was enough mint in the same place at the same time .
But do we , necessarily , need mass ? After all , Einstein showed us that energy and mass are equivalent . Grab two atoms of hydrogen and mash them together intemperately enough and some of their mass will be converted to energy . So , if energy and mass are equivalent , why ca n’t energy create a black gob ?
Technically , it can . Sure , it ’s hard , because one of the trait of muscularity ( as anyone who has stir up up a popcorn kernel bed ) is its tendency to reject to be restrain to a little distance . But lets say it was . Let ’s say there was a light so acute , and so hard , that it equaled the concentration of plenty take to make a contraband muddle . Some say that this light would , essentially , ensnare itself inside its own consequence sensible horizon . It would collapse on itself and become a black hole .
We have n’t get a line it , but it ’s been give the name kugelblitz – from the German Word of God for ball lightning . So if you see a light suddenly blink off , investigate ! You may have find the first physical good example . ( For safety reasons , we recommend that you not get too close , and apply a very recollective stick to poke it . If the stick gets stretch out and vanish down the darkness , you ’ve plant it . )
