The Forgotten Victims of Jack the Ripper

We are fascinated by the Ripper – he is a legend, with countless books and films dedicated to his mystery. There’s an entire field dedicated to the study of his crimes: Ripperology.

 

But who were his tragic victims? Let’s find out…

 

 

The Forgotten Lives Of Jack The Ripper’s Victims
By Elisabeth Sherman

 

Because he was the first celebrity serial killer, Jack the Ripper’s victims and their tragic lives were always overshadowed by the man himself.

 

“Head to London for a dose of the macabre, and you won’t be disappointed. Guided tours of the Whitechapel district — where in 1888 legendary serial killer Jack the Ripper brutally cut the throats of five prostitutes and removed their organs — continue to draw in droves of tourists to this day.

 

There’s the Jack the Ripper museum, too, which opened last year to controversy. According to historian Fern Riddell, the museum intended to tell the “history of women in the East End,” but activists said the museum mainly “glamorises sexual violence against women.”

 

Beyond the outcry, it’s not entirely surprising that the museum shifted focus away from Jack the Ripper’s victims and back onto the killer himself. After all, the mystery surrounding who he was and his motivations never ceases to captivate an audience — so much so that there’s a whole field dedicated to the study of his crimes: Ripperology.

 

As some have noted, though, at its core this “thriving Ripper industry” is misogynistic, and “commercially [exploits] real-life murder victims.”

 

Regardless of the truths these criticisms may highlight, fascination with Jack the Ripper and serial killers like him endure — and experts don’t see that changing any time soon. As appears in Psychology Today, “the incomprehensibility of such actions drives society to understand why serial killers do incredibly horrible things…serial killers appeal to the most basic and powerful instinct in all of us—that is, survival.”

 

This, coupled with media market dynamics, helps cement sustained public interest in figures like Jack the Ripper…”

Einstein said this was impossible, but the Hubble just proved him wrong

This is how amazing the Hubble is (it’s even proving Einstein wrong lately) —

 

“Imagine a firefly moving from one side of a U.S. quarter to the other side. You have to detect this movement from 1,500 miles away,” he says. “Second, there is a bright light bulb [the white dwarf] next to the firefly. And you have to detect the small movement of the firefly in the glare of the bright light bulb.”

Einstein’s ‘Impossible’ Experiment Finally Performed
The Hubble telescope just weighed a star using a technique the famed physicist described but said humanity would have “no hope” of using.

 

By Nadia Drake

 

“Leave it to the Hubble Space Telescope to prove Albert Einstein wrong. Or at least, unnecessarily pessimistic.

 

Recently, Hubble spied a dead star about 18 light-years away warping the light of a more distant star that appeared to pass behind it. Einstein predicted this effect would happen based on his general theory of relativity, but he then claimed scientists had “no hope” of actually seeing it.

 

Of course, he wrote that dour phrase nearly 60 years before humans launched a rather impressive piece of hardware into Earth’s orbit.

 

Now, Hubble has managed to witness the spectacle, and astronomers were able to read clues carried in the curved starlight and discern the mass of the dead star, called Stein 2051B. The result perfectly matches a prediction of the star’s mass made a century ago…”

Massive Black Hole Smash Ups Observed

It wasn’t very long ago that black holes were considered merely theoretical — Einstein predicted the existence of black holes, but the first one was not discovered until 1971. Now with LIGO (the Laser Interferometer Gravitational-Wave Observatory) three massive black hole collisions have been measured to date, the most recent, a merger of “a pair of mammoth black holes resulting in a pit of infinitely deep darkness weighing as much as 49 suns” — the science of black holes is in full swing…

Third Gravitational Wave Detection, From Black-Hole Merger 3 Billion Light Years Away

By DENNIS OVERBYE

 

“The void is rocking and rolling with invisible cataclysms.

 

Astronomers said Thursday that they had felt space-time vibrations known as gravitational waves from the merger of a pair of mammoth black holes resulting in a pit of infinitely deep darkness weighing as much as 49 suns, some 3 billion light-years from here.
This is the third black-hole smashup that astronomers have detected since they started keeping watch on the cosmos back in September 2015, with LIGO, the Laser Interferometer Gravitational-Wave Observatory. All of them are more massive than the black holes that astronomers had previously identified as the remnants of dead stars.
In less than two short years, the observatory has wrought twin revolutions. It validated Einstein’s longstanding prediction that space-time can shake like a bowlful of jelly when massive objects swing their weight around, and it has put astronomers on intimate terms with the most extreme objects in his cosmic zoo and the ones so far doing the shaking: massive black holes.

“We are moving in a substantial way away from novelty towards where we can seriously say we are developing black-hole astronomy,” said David Shoemaker, a physicist at the Massachusetts Institute of Technology and spokesman for the LIGO Scientific Collaboration, an international network of about 1,000 astronomers and physicists who use the LIGO data….”
