The first-ever image of a black hole has been released

Looks like we have a bunch of smart guys in here.. Answer this.. What is the most important hole of all?


Lol

That is a question only a mom can answer, I think.

Maybe. If the four orders of magnitude more massive means it is ingesting four orders of magnitude more of its surrounding mass than Sag A*, assuming perfect conversion, the intensity of the of the emitted radiation would be approximately four orders of magnitude greater by E=mc^2. By the inverse square law, M87 would have to be 16 orders of magnitude further away than it is for the intensity of the radiation reaching Earth to be the same as that reaching the Earth from Sag A*.

So, assuming I am not making too many ass_umptions, and I actually know what I am talking about, the intensity of the radiation from M87's SMBH reaching Earth may very well be on the order of two orders of magnitude greater than the intensity of the radiation reaching Earth from Sag A*, and like any brighter object, it would also be easier to photograph.

The inverse square law only attaches to the area of a flat plane. The inverse cube law attaches when you're trying to determine area in three dimensions.

A base example 1 x 1 = 1. But for plane area 2 x 2 = 4 (doubling the side dimensions quadruples the flat plane area).

Adding the 3d dimension (depth), doubles the flat plane area. 2 x 2x 2 = 8 (now cubic area) For spherical area, Pi becomes the coefficient.

For point source illumination, increasing the distance of an object by 1.4 times, (roughly the square root of two) would result in it receiving 1/2 the light. (That's how they come up with those screwy F stop numbers). Each F stop more closed halves the available light, and is calculated my multiplying the previous number by 1.4.

This is a very old, (read ancient), joke. The answer is the hole that removes the solid waste from your body. Without it functioning properly, every thing else in the body craps out. <pun intended..

You post made me feel like I was back in 5th grade. cheers!

Small step for the photography (200 ppl only involved, 201 of them on the calc),
but a BIG LEAP for the forum, try'n to looks like "we have a bunch of smart guys in her..."
hell yeah, literally

Wow just wow!

6.5 bllion times more massive than our sun. Is that diameter, volume, or mass(ive) ?

 

[ButtonPusher]

When they say stuff like "6.5 billion times more massive than our sun", my mind can't comprehend that. If the sun was a marble, what's 6.5 BILLION times more massive?

 

[SBKenn]

True, but diameter is a lot more than if it is area or volume !

Using the word massive refers to mass.

Why did they use a galaxy so far away? 55 million light years? The milky way is only 120,000 light years across with the Andromeda galaxy being around 1.2 million light years away.

I'm sure they have their reasons, but it isn't like galaxies are rare, we have over 100 within a million light tears of us.

There is something here https://www.bbc.co.uk/newsround/47868061

"The scientists have also tried to take a picture of the Sagitarius A*, the black hole which sits at the centre of our galaxy, some 26,000 light years away.

However they've said this is more difficult to photograph than the big one in M87, because our black hole is not as big or bright."

And I think I read somewhere that they plan to try our black hole soon.

I wonder if the U.S.S. Cygnus, commanded by Dr. Hans Reinhardt, is perched at the edge while final calculations are being made before entering it.

Wonder where it leads to? See everyone on the other side!

It doesn't lead anywhere. There are no wormholes. That concept was invented by Einstein because he couldn't explain quantum entanglement. So he though that particles communicate slower than light through some kind of "wormhole". Einstein couldn't accept that something can be faster than light, so he insisted on this failed wormhole concept till his death.

A few years after Einstein died, British genius mathematician John Bell envisioned an experiment to prove or disprove Einstein's assumption. The experiment was later conducted (in 1980'es) where it was proven that Einstein was wrong and Quantum Entanglement is actually thousands of times faster than light. That wasn't the first time Einstein was wrong, but it was one of his biggest blunders.
