How are we not just in a black hole right now?
Because black holes are actually white holes.

>>16952687if so, where is the singularity?
>>16952687The mass is spread out like a gaping anus that gaped too wide. A black hole can have any mass as long as it's packed densely enough.
>>16952687Est. mass of universe - 10e54 kgEst. Schwarzschild radius of universe - 7.8 lyEst. comoving radius of universe - 4.7E10 lyThat's why we're not a black hole right now
>>16952921Yup, OP is an idiot. The better question is how come the universe didn't collapse into a black hole when it was younger and much, much smaller.
>>16952934what if it collapsed and we are inside it now
>>16953076Nothing changes. It would have to be one strange blackhole, especially since every astronomical observation ever made lines up with us not being inside a blackhole.
>>16952921>>16952934>Est. Schwarzschild radius of universe - 7.8 lyNo? Where the fuck did you get this? It's 2GM/c^2.2(6.674e-11)(10^54) = 1.3348e44 / (2.998e8)^2 = 1.4850906e27m = 156974200280 lyThat's ~1.57e11 ly. Which is bigger than 4.7e10 ly.
>>16953100>every astronomical observation ever made lines up with us not being inside a blackholedo we really know how astronomical observations work behind a black hole's event horizon though?
>>16953156If we didn't then GR would no longer work and all the observations wouldn't match what we would expect.
>>16953165they don't
A black hole is a solution to the Einstein field equation. Its not just a function of mass and density. That mass has to uniformly distributed in a sphere with nothing outside to satisfy the black hole solution assumptions.
>>16952934Because its was that dense everywhere. Every point would have equal claim to be the singularity
>>16953156Yes. The solution that tells you blackholes exists tell you the metric inside the black hole. And its not the FLWR metric.
>>16953217>That mass has to uniformly distributed in a sphere with nothing outside to satisfy the black hole solution assumptions.No it doesn't.
>>16952687Universe is inside a black hole. It just doesn't really have any effect on us from our perspective.
>>16952820Why didn't it collapse into one giant black hole when Universe was densely packed?
>>16953267Because space itself was also jammed in there. Anselm's ontological God created the universe, not Euclid
>>16953237Yes it does. The Schwatzchild solution describes spherically symmetrical mass, vacuum outside the black hole, and a cosmological constant of zero.
>>16953267Because that isn't what the Einsteins field equations do for a uniformly distributed mass.
>>16953494Einstein fucked his cousin
>>16953493The Schwarzschild exterior is only a function of total mass and doesn't care how that mass is distributed internally, that's literally whole point. You don't need uniform density, you don't need a sphere of mass, the exterior metric is the same regardless of what the interior looks like. This has nothing to do with the interior of a black hole in the first place. Dumbass spherical cow retard.
>>16955179t. Retard.The total mass doesn't even appear in the Einstein field equation. Its the mass distribution. And Schwartchild describes a radially symmetric mass surrounded by vaccum with zero cosmological constant.
