I don't know whether you see supermassive black holes as bullshit objects or not. Otherwise, there is a red supergiant star "Stephen 2-18" with radius about 2000 times the radius of the sun.
Or do you want most massive?

>>11660728
supermassive black holes
biggest one we know about is TON 618, which has a mass of 66 billion suns, which means it has a radius about 1300 times that of the distance between the sun and the earth

Youre mostly empty space

>>11661013
This and everything else actually

>>11660728
probably some star we don't even know of...just imagine what horrors are there in the universe RIGHT NOW. shit that would erase humanity in a nanosecond

>>11660728
Deez nuts.

Everything is "mostly empty space." Atoms are "mostly empty space."

I always hated this high school level argument. Just because mass is centralized in the nucleus doesn’t mean the rest of the atom is “empty space”. Electrons are responsible for half the charge, nearly all of the atom’s chemistry, and quantum mechanics tells us the electrons is probably more like a spread out wave. Since other atoms are surrounded by electrons too which repeal one another, atoms definitely don’t treat one another like they are “empty space”. And since you are made of these atoms it’s obvious why it doesn’t feel empty. Just because high energy alpha particles can pass through gold foil in rutherfords experiment doesn’t mean this space is actually empty. I guess it’s good for demonstrations how small the nucleus is.

Even in a very dense star's core?

>>11660728
Everything is mostly empty space. Learn what an atom is dumbass

>>11661724
Still atoms

>>11660792
>black holes
that could be just mostly empty space behind the EH, with all the mass in the center

A neutron star is genuinely solid, and they're all about the same size. So there's your answer OP.

>>11660953
Do we know the actual size of black holes or just their event horizon?

>>11660728
Your mother

>>11661859
it's all just guesstimates beyond the EH
even a big bang occurring inside couldn't get out

>>11661858
If 1987A is this, then it would be even denser

that guy is weird

>>11661859
Try not to think about a black hole as a physical object, its a region of extremely warped spacetime.

>>11661858
They're not exactly large, though. I think OP wants the largest "coherent" object measured in extent, not mass/density.

https://en.wikipedia.org/wiki/IC_1101

>IC 1101 is a supergiant elliptical galaxy at the center of the Abell 2029 galaxy cluster and is one of the largest known galaxies. Its halo extends about 600 kiloparsecs (2 million light-years) from its core, and it has a mass of about 100 trillion stars. The galaxy is located 320 megaparsecs (1.04 billion light-years) from Earth.

>I'm talking about something that isn't mostly empty space.
Technically speaking, you are mostly empty space as well.

>>11660953
Just use AU and let people google it.

>>11661625
all evidence till now points to atoms being mostly "empty space" and that their corpus and interactions are mostly sustained by electrodynamics
on the other hand quantum field theory basically implies theres a "aether simil" where all matter come to exist by way of perturbations(vibration) of specific character in quantum fields...
