Space Mysteries in our Solar System — Do Black Holes Create New Universes?

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.

In a breakthrough Experiment scientists are now seeing past and the Future

Posted by in categories: cosmology, robotics/AI

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.

The Big Bang Never Happened — And There Might Be Traces Of An Earlier Universe, Scientist Claims

Posted by in categories: cosmology, mathematics, singularity

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.

Hawking’s black hole paradox explained

Posted by in categories: cosmology, media & arts, particle physics, quantum physics

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.

Before the Big Bang 6: Can the Universe Create Itself?

Posted by in categories: cosmology, information science, media & arts, neuroscience, particle physics, quantum physics, time travel

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:

Can stringy physics rescue the universe from a catastrophic transformation?

Posted by in categories: cosmology, particle physics, quantum physics

Our universe may be fundamentally unstable. In a flash, the vacuum of space-time may find a new ground state, triggering a cataclysmic transformation of the physics of the universe.

Or not. A new understanding inspired by string theory shows that our universe may be more stable than we previously thought.

Within the first microseconds of the Big Bang, the universe underwent a series of radical phase transitions. The four forces of nature — electromagnetism, gravity, the strong nuclear force and the weak nuclear force — were at one time unified into a single force. Physicists do not know the character or nature of this force, but they do know that it didn’t last long.
