Black holes are one of the more well-known features of space, a science fiction staple, and something we still don’t know much about. We do know…
How Do Black Holes Die?

In other words, the study suggests black holes might actually burrow into a kind of multidimensional object called a brane, and give birth to an entirely new universe in another colossally big bang.
A new study has revealed that researchers have used artificial intelligence to create a map that allows them to predict the distribution of dark matter throughout the universe.
The new study has been published in the Astrophysical Journal and shows that researchers have taken a different approach to creating a model of the distribution of dark matter. So far, researchers know that dark matter makes up 80% of the universe, and creating a model of the distribution of dark matter allows cosmologists to construct what is called a “cosmic web”.
With this cosmic web, cosmologists and researchers will be able to see how dark matter impacts the motion of galaxies in the past, present, and future. Researchers in the new study used machine learning, a branch of artificial intelligence, to construct a new model. The AI was fed a large set of galaxy simulations that include galaxies, dark matter, visible matter, and gases.
Black holes are terrifying objects that never let anything escape them!
Scientists just brought black holes to the human planet.
A physicist from the University of Campinas in Brazil isn’t a big fan of the idea that time started with a so-called Big Bang. So Instead, Juliano César Silva Neves imagines a collapse followed by a sudden expansion, one that could even still carry the scars of a previous timeline.
Updated version of the previous article.
The idea itself isn’t new, but Neves has used a fifty-year-old mathematical trick describing black holes to show how our Universe needn’t have had such a compact start to existence. At first glance, our Universe doesn’t seem to have a lot in common with black holes. One is expanding space full of clumpy bits; the other is mass pulling at space so hard that even light has no hope of escape. But at the heart of both lies a concept known as a singularity – a volume of energy so infinitely dense, we can’t even begin to explain what’s going on inside it.
Today, one of the biggest paradoxes in the universe threatens to unravel modern science: the black hole information paradox. Every object in the universe is composed of particles with unique quantum properties and even if an object is destroyed, its quantum information is never permanently deleted. But what happens to that information when an object enters a black hole? Fabio Pacucci investigates.

Richard Gott, co author with Neil De Grasse Tyson of “Welcome to The Universe” argues the key to understanding the origin of the universe may be the concept of closed time like curves. These are solutions to Einstein’s theory that may allow time travel into the past. in this film, Richard Gott of Princeton University explains the model he developed with LIxin Li. Gott explores the possibility of a closed time like curve forming in the early universe and how this might lead to the amazing property of the universe being able to create itself. Gott is one of the leading experts in time travel solution to Einstein’s equations and is author of the book “Time Travel In Einstein’s Universe”.
This film is part of a series of films exploring competing models of th early universe with the creators of those models. We have interviewed Stephen Hawking, Roger Penrose, Alan Guth and many other leaders of the field. To see other episodes, click on the link below:

According to the predominant cosmological model, the first stars in the Universe formed roughly 100,000 years after the Big Bang. Known as Population III stars, these…
Researchers observed an ultra-rare particle interaction that reveals the half-life of a xenon-124 atom to be 18 sextillion years.

New mathematical formulation means huge paradigm shift in physics would not be necessary.
