I don't understand what you mean by "gravity that is external".
These objects exist.
I am not questioning whether the object in the photo exists - it does. I mistakenly used eternal interchangeably for infinity.
I'm referring to stars original mass that is quantifiable pre- black hole…..then a finite mass collapses and creates infinite density, infinite gravity within a volume that is infinitely small.
According to the big bang theory the universe is finite. Black hole theory presumably lives within this big bang universe. So if the universe itself is finite, and the stars are finite, while functioning according the laws of physics… all am asking is how can something exist within a finite universe that creates "infinite" gravity, density and size ? In order to get the characteristics of a black hole mathematically you have to divide by zero…..now if the definition of infinite is - "limitless or endless in space, extent, or size; impossible to measure or calculate.", then using science is impossible outside of simulations based on these theoretical mathematical assumptions. Because there is an never will be a way to test these concepts….however we can observe our universe and this is where it gets interesting….
"ALMA has revealed the telltale signs of eleven low-mass stars forming perilously close -- within three light-years -- to the Milky Way's supermassive black hole, known to astronomers as Sagittarius A* (Sgr A*). At this distance, tidal forces driven by the supermassive black hole should be energetic enough to rip apart clouds of dust and gas before they can form stars."
Also, a gas cloud "G2" came within 36 light MINUTES of the black hole mentioned above and survived….
Astronomers watched in fascination as an object called G2 appeared to edge closer to our Milky Way’s central black hole. But G2 survived!
As you know, one of the test of a sound theory is how accurately can it make predictions…there are many examples like the ones above, of observations that are unexpected given what the current paradigm of cosmology expects to find…
