The mystery of the naked black hole

A new version of a still-to-be-properly-understood stellar object, it would appear.

This of interest to you, mate?

I thought this article was about obama’s head?

Careful folks...

Any time an object seems to be manipulated by another object that can’t be seen, it’s a black hole. Too bad the math shows that black holes cannot exist.

[TruthWillWin]

Yes, with that title this thread could get interesting.....

I thought it was about Reggie and what brought tears to obama's eyes.

Sorry everybody

[Harmless Teddy Bear]

It ate them.

What math is that? Common Core?

I kinda thought it might be about something that Laz might hit.

WARNING! Do NOT Google this title!

??? Who but the completely clueless (not you, mate) still use the Goog? Why not simply click on the link and read the article referenced in the thread?

The idea of a “black hole” was first proposed by John Mitchell in 1783. He hypothesized that there might exist massive bodies so big that their “escape velocity” would be greater than the velocity of light. This is the original source of the mistake.

The mistake is this: yes, a stone thrown up from such a body could never escape: it would lose energy by losing velocity (E = 1/2 mv^2), and hence surely be brought to rest and pulled back down. But light cannot lose velocity; rather it loses energy by becoming redder (E = h nu).

If you do the math, you will discover that a light ray emitted from a massive body, no matter how massive, can never be red shifted into extinction. I have the math on my home machine; I’ll bring it in and post it.

I am soooo glad this didn't have anything to do with Moochelle.

Is that wrong?

“...a merger of two galaxies”

I’ve been through this crap. The little planets are going to get SCREWED OVER, big time.

[Do the math]

Black holes exist. The famous mathematician and engineer Laplace was the first person to consider the existence of black holes. He was correct and you are wrong. Scientists have found hundreds of black holes.

You’re using classical physics to analyze something predicted by relativity. Not even wrong.
