The Big Bang may mark an end—not the start—of a previous universe's aeon. Penrose's theory sees the universe as an eternal ...

We review pedagogically some of the basic essentials regarding recent results intertwining boundary conditions, the algebra of constraints and hidden symmetries in quantum cosmology. They were ...

A new cosmological simulator logs its scientific predictions and refutations in real time, storing hashes in blockchain with full offline ...

Could the Universe have been born inside a black hole? This question, raised by a team of scientists, challenges the Big Bang ...

Includes bibliographical references (pages 447-486) and index Between 1920 and 1970, cosmology became a branch of physics. This text examines how the big bang theory drew inspiration from, and ...

What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

In the realm of physics, the speed of light is considered one of the most fundamental constants in the universe, dictating ...

New simulations reproduce high-redshift galaxies seen by JWST and propose a radical cosmological shift beyond ΛCDM. To simulate the universe with ...

India's contributions to mathematics are well-documented. The concept of zero, the decimal system, algebra, and trigonometry ...

The James Webb Space Telescope is only three years into operations, yet it keeps slipping the cosmic rug out from under ...

There are new hints that the fabric of space-time may be made of "memory cells" that record the whole history of the universe ...

The earliest and most distant supermassive black hole discovered thus far by JWST is CEERS 1019, which existed just 570 ...
