Closest Supermassive Black Hole Pair to Earth Discovered, On Verge of Collision
Newsweek via msn ^ | 30 November 2021 | Robert Lea

Posted on 11/30/2021 9:11:05 PM PST by blueplum

Astronomers have discovered the closest pair of supermassive black holes to Earth. Not only are they the most proximate objects of this type to our planet, but they are also closer to each other than any such pairing ever before observed.

This closeness indicates that the black holes, which are 89 million light-years away from Earth in the galaxy NGC 7727 in the constellation Aquarius, are moving towards each other and will eventually collide and merge, forming an even more massive black hole....

...The two supermassive black holes are separated by just 1,600 light-years, half the separation ...

Well, it has long, long, long, long , long, …long since happened. The article states they are 89 million light years away and only 1600 light years apart. So whatever was going to occur happened long ago even at sublight rates of closure.

The distance is indeed vast but the time is even longer.

No worries, the Ohmicron variant will kill us all long before the black holes will.

If you keep getting all the jabs they want for you, you won’t feel a thing...

On Verge of Collision

Since we are seeing the state of things 89 million years ago, that "verge" is long in the distant past.

"will we feel it and how will we feel it?"

Gravity strains your body. When you stand up, your body is shorter than when you are lying down. Strain is measured in how many inches you shrink compared with how many inches tall you are. In most things the shrinkage is quite small, so strain is often measured in micro-inches per inch of length.

A micro inch is a millionth of an inch. The smallest measurable strain using conventional techniques is about one micro-inch per inch. That's one inch per million inches, or one inch in 17 miles. That, in itself is something you would never feel. If you were 70 inches tall and shrank that amount, you would shrink about 0.0001 - a tenth of a thousandth of an inch. That's less than one tenth the thickness of a human hair.

Gravity waves are many orders of magnitude smaller than that. One analogy places the gravity wave sensitivity detectors as sensitive to stretching the distance from the earth to the sun by an amount equal to the diameter of a hydrogen atom. You won't feel that!

No, we won’t feel it. We will have died move that 1,500 years before it happens.

We have 1,600 years to perfect that technology.

Typical stupid reporting...
These black holes WERE that close 89 million years ago...
Who knows what their situation is now...
Maybe they should point their scopes towards Chicago if they want to observe “current” black hole events...
