The ‘ultramassive’ black hole discovery has big implications for our future understanding of space.

The Big Bang may have not been alone. The appearance of all the particles and radiation in the universe may have been joined by another Big Bang that flooded our universe with dark matter particles. And we may be able to detect it.

In the standard cosmological picture the early universe was a very exotic place. Perhaps the most momentous thing to happen in our cosmos was the event of inflation, which at very early times after the Big Bang sent our universe into a period of extremely rapid expansion.

Scientists at Durham University say the black hole is 30 billion times the size of the sun.

The story of modern physics has been one of reductionism. We do not need a vast encyclopedia to understand the inner workings of Nature. Rather, we can describe a near-limitless range of natural phenomena, from the interior of a proton to the creation of galaxies, with apparently unreasonable efficiency using the language of mathematics. In the words of theoretical physicist Eugene Wigner, ‘The miracle of the appropriateness of the language of mathematics for the formulation of the laws of physics is a wonderful gift which we neither understand nor deserve. We should be grateful for it.’

The mathematics of the twentieth century described a Universe populated by a limited number of different types of fundamental particles interacting with each other in an arena known as spacetime according to a collection of rules that can be written down on the back of an envelope. If the Universe was designed, it seemed, the designer was a mathematician.

Today, the study of black holes appears to be edging us in a new direction, towards a language more often used by quantum computer scientists. The language of information. Space and time may be emergent entities that do not exist in the deepest description of Nature. Instead, they are synthesized out of entangled quantum bits of information in a way that resembles a cleverly constructed computer code. If the Universe is designed, it seems, the designer is a programmer.

A sparsified SYK model is constructed using learning techniques and the corresponding traversable wormhole dynamics are observed, representing a step towards a program for studying quantum gravity in the laboratory.

WASHINGTON, Nov 30 (Reuters) — In science fiction — think films and TV like “Interstellar” and “Star Trek” — wormholes in the cosmos serve as portals through space and time for spacecraft to traverse unimaginable distances with ease. If only it were that simple.

Scientists have long pursued a deeper understanding of wormholes and now appear to be making progress. Researchers announced on Wednesday that they forged two miniscule simulated black holes — those extraordinarily dense celestial objects with gravity so powerful that not even light can escape — in a quantum computer and transmitted a message between them through what amounted to a tunnel in space-time.

Researchers have created a computer simulation of early universe in the epoch after the Big Bang. It’s designed to help them interpret real data in future.

Generative AI, the technology behind ChatGPT, is going supernova, as astronomers say, outshining other innovations for the moment. But despite alarmist predictions of AI overlords enslaving mankind, the technology still requires human handlers and will for some time to come.

While AI can generate content and code at a blinding pace, it still requires humans to oversee the output, which can be low quality or simply wrong. Whether it be writing a report or writing a computer program, the technology cannot be trusted to deliver accuracy that humans can rely on. It’s getting better, but even that process of improvement depends on an army of humans painstakingly correcting the AI model’s mistakes in an effort to teach it to ‘behave.’

Humans in the loop is an old concept in AI. It refers to the practice of involving human experts in the process of training and refining AI systems to ensure that they perform correctly and meet the desired objectives.
