Lots of those nifty ‘artists renderings’ of which you’re so fond.
How else would you prefer the phenomena of merging black holes to be portrayed? Raw data from the Laser Interferometer Gravitational-Wave Observatory?
Lots of "art" but very little science going on around there. Don’t you love their Lima bean shaped event horizons? Is the "singularity" postulated to occupy (how can something with no dimensionalality be said to ‘occupy’ anything?) the center of that event horizon being similarly distorted into a no-sized bean?
In the Electric Universe Black Holes can’t exist. . . and since we live in an Electric Univers so Black Holes don’t exist. There are alternative explanations for the observations the Gravity Cosmologists conclude mean they exist. . . The energy, the "Black Hole Corona" is a glow discharge plasma easily explicable in an Electric Universe as are Super Novae, including the newly discovered cyclic Super Novae that have the Newtonian gravity Cosmologists stunned in shock.
