re: Can someone confirm this astronomical calculation re: distance of nearest black hole?

I wanted an excuse what I learned about red shift in this thread but failed.
Find a doc that uses graphics for it. As an adult, you’ve probably no concept of what the kid can understand, and it’s far less than what you assume. Hell, Brits don’t get how it doesn’t take four hours on a train to go from Atlanta to the “north.”

Does the black hole of Calcutta count?
Posted on 8/7/25 at 10:08 pm to 4Bagger
Grok says this is the closest black hole
I assumed two 0.1mm thick sheets of paper
So…. If we are to believe Grok, it appears you were exaggerating

The black hole is all around us. Our universe is already in a black hole. Tigerdroppings is the singularity.

“Shitifino, baw” is the correct answer.

If it's 98 million times father from earth than the sun would it be 2mm x 98m? If so, then that's 121 miles. But I may be wrong again.

It’s 0.2mm…. Which multipled by 98m is 12.1 miles and in the ballpark of your 20 mile estimate.
So Grok failed at math or misinterpreted my prompt..
ETA: dumbass Grok thinks there’s 1.6 million meters in a mile.

Sounds good to me.

The distance from the center of the Earth to the center of the Sun is also known as an Astronomical Unit (AU for short). The nearest black hole, Gaia BH1, is about 98,611,760 AU away.
If I assume the sheets of paper are laid longitudinally and round up(for ease of calculation) to 12 inches per page, then we will say 2 feet is the space between the blue and yellow sheets.
2 x 98611760 (197,223,520) is the representation of the distance to the black hole in feet in this model.
Divide by 520, and that is your distance in this model to the black hole.
That works out to 37,353 miles. Slighlty more than 20 miles.
My calcs are always suspect.

I appreciate the response. My calculation was based on the sheets of papers being stack on top of each other with each sheet being .1mm, so the distance between the two outer sheets is .2mm. That seemed like an easier way to illustrate.
What is the 520?

I think that's a fairly close calculation, but how far off am I?
I checked the math and assuming you are using a standard 8.5x11 sheet the calculations prove exactly 20 miles from the blue sheet.
Well done.

I find it funny just how little people understand distances in space. Even from the Earth to the Moon, most people see it as...
O__o
When it is actually...
O____________________________o
(You can fit thirty or so Earths between the Earth and the moon)

Tell him there are wandering black holes and we’d have relatively little warning if there were one right outside our solar system. Then send him to bed.

Let me try again.
The nearest black hole, Gaia BH1, is about 98,611,760 AU away.
Using stacked paper as you pointed out, and saying .2 millimeters is the scaled AU measurement you would say .2 x 98611760 (19,722,352) is the representation of the distance to the black hole in mm in this model.
1,609,000 mm per mile so 19,722,352/1,609,000
That works out to 12.25 miles. 20 is not that far off.

It's pretty wild.

Sagittarius A* (Sgr A*) is a supermassive black hole located at the center of our Milky Way galaxy. It has a mass about 4.3 million times that of our Sun and is approximately 26,000 light-years from Earth. While not exceptionally large compared to black holes in other galaxies, its proximity to us allows for detailed study, providing valuable insights into black hole physics and galaxy evolution.

Pretty sure that's not true.

I got as small as millimeters in my calculation and sheets of paper are usually .1mm thick.
I just meant if the earth and a piece of paper were .1mm thick the sun would be the 10,000+ sheets away not 3
