  By the star physicist and author of multiple #1 Sunday Times bestsellers, a major and definitive narrative work on black holes and how they can help us understand the universe.  
  At the heart of our galaxy lies a monster so deadly it can bend space, throwing vast jets of radiation millions of light years out into the cosmos. Its kind were the very first inhabitants of the universe, the black holes. 
  Today, across the universe, at the heart of every galaxy, and dotted throughout, mature black holes are creating chaos. And in a quiet part of the universe, the Swift satellite has picked up evidence of a gruesome death caused by one of these dark powers. High energy X-ray flares shooting out from deep within the Draco constellation are thought to be the dying cries of a white dwarf star being ripped apart by the intense tides of a supermassive black hole – heating it to millions of degrees as it is shredded at the event horizon. 
  They have the power to wipe out any of the universe’s other inhabitants, but no one has ever seen a black hole itself die. But 1.8 billion light years away, the LIGO instruments have recently detected something that could be the closest a black hole gets to death. Gravitational waves given off as two enormous black holes merge together. And now scientists think that these gravitational waves could be evidence of two black holes connecting to form a wormhole – a link through space and time. It seems outlandish, but today’s physicists are daring to think the unthinkable – that black holes could connect us to another universe. 
  At their very heart, black holes are also where Einstein’s Theory of General Relativity is stretched in almost unimaginable ways, revealing black holes as the key to our understanding of the fundamentals of our universe and perhaps all other universes. 
  Join Professors Brian Cox and Jeff Forshaw in exploring our universe’s most mysterious inhabitants, how they are formed, why they are essential components of every galaxy, including our own, and what secrets they still hold, waiting to be discovered. 
  Supplemental enhancement PDF accompanies the audiobook.

  Endometriosis - Manage Pelvic...

  Endometriosis and adenomyosis are two chronic conditions that significantly affect the lives of women around the world. Both are often misunderstood, underdiagnosed, and associated with pelvic pain, yet they are distinct in their causes and manifestations. Understanding these conditions is crucial for improving awareness, diagnosis, and treatment options. 
  Endometriosis is a disorder in which tissue similar to the lining of the uterus grows outside the uterus, often causing inflammation, pain, and the formation of adhesions. This misplaced tissue can attach to organs such as the ovaries, fallopian tubes, and the outer surface of the uterus. The most common symptom of endometriosis is pelvic pain, which can vary from mild to debilitating. Women with endometriosis often experience pain during menstruation, intercourse, and bowel movements, and may also suffer from infertility. The condition affects approximately 10% of women worldwide, yet many go undiagnosed for years due to the subtlety of its symptoms and the lack of awareness among both patients and healthcare providers. 
  Adenomyosis, on the other hand, occurs when the tissue that normally lines the uterus grows into the muscular wall of the uterus. This can cause the uterus to become enlarged and tender, often resulting in heavy menstrual bleeding, cramping, and pelvic pain. Although adenomyosis shares some symptoms with endometriosis, such as pain and menstrual irregularities, it is distinct in its pathology and the way it impacts the body. Unlike endometriosis, adenomyosis is more directly related to the uterus itself, leading to a different set of challenges in terms of diagnosis and treatment.
