A Theory By North Carolina State University Professors Rules Out Einstein’s Theory of General Relativity
Larry Silverberg and his research partner Jeffrey Eischen From North Carolina State University have proposed a surprising new model of physics that could entirely rewrite the way we have studied physics so far.

Mystery of Dark Matter is going to be solved soon
Have you ever wonder what is the universe made of? If you want to find the answer in syllabus books then it says the universe is made of energy and matter. If you ask the same question to a scientist then he will say it's dark stuff (Dark energy & Dark matter) then if you ask him what is dark matter? then his reply is probably is it's a riddle for science to solve. We are going to tell you about the mystery of dark matter and how scientists of LHC (Large Hadron Collider) gonna solve this mystery.

Primordial black holes and the search for dark matter from the multiverse
Astronomers are studying black holes that could have formed in the early universe, before stars and galaxies were born. Such primordial black holes (PBHs) could account for all or part of dark matter, be responsible for some of the observed gravitational waves signals, and seed supermassive black holes found in the center of our Galaxy and other galaxies

Astronomers Get Their Wish, and the Hubble Crisis Gets Worse
On December 3, humanity suddenly had information at its fingertips that people have wanted for, well, forever: the precise distances to the stars. “You type in the name of a star or its position, and in less than a second you will have the answer,” Barry Madore, a cosmologist at the University of Chicago and Carnegie Observatories, said on a Zoom call last week. “I mean …” He trailed off.

Flow of time is just an illusion
Many good stories begin with this magical phrase, but have you ever thought that "what is the story of time?" Does time exist? We always say time can be spent, time is money, we waste time, we are trying to save time, but what do we really know about the time? Is time an illusion? According to physicist Brian Greene, "all the time exist at once in spacetime"

Scientists find hidden ‘super planet’ in breakthrough observation
Astronomers have discovered a cold brown dwarf – otherwise known as a “super planet” – for the first time using a radio telescope. Brown dwarfs are vast, sized between 15 and 75 times the mass of Jupiter, and have gaseous atmospheres similar to some of the planets in our solar system. They are also often known as “failed stars” because of the way that they shine.

Has the hidden matter of the Universe been discovered?
Astrophysicists consider that around 40% of the ordinary matter that makes up stars, planets and galaxies remains undetected, concealed in the form of a hot gas in the complexe cosmic web. Today, scientists at the Institut d’Astrophysique Spatiale (CNRS/Université Paris-Saclay) may have detected, for the first time, this hidden matter through an innovative statistical analysis of 20-year-old data. Their findings are published on November 6, 2020 in Astronomy & Astrophysics.

What 50 gravitational-wave events reveal about the Universe
Astronomers observed 39 cosmic events that released gravitational waves over a 6-month period in 2019 — a rate of more than one per week. The bounty, described in a series of papers published on 28 October, demonstrates how observatories that detect these ripples — usually created by the merging of two black holes — have dramatically increased their sensitivity since the first identification was made in 2015.

Why is there a normal galaxy sitting at the edge of the Universe?
Aided by a trick of gravity, astronomers have found a normal galaxy. Big deal, right? The thing is, where they found it is not normal: The light we see from it left the galaxy 12.4 billion years ago, meaning we’re seeing it as it was when the Universe itself was only 1.4 billion years old! That’s what makes this so weird. A normal galaxy has no business being there when the cosmos was so young. But yet, there it sits.

NASA finds active galaxy far, far away that looks like a "Star Wars" TIE fighter
Scientists have spotted an active galaxy far, far away — and it looks like it could join Darth Vader's fleet. Located 500 million light-years away in the Cassiopeia constellation, Galaxy TXS 0128+554 bears a striking resemblance to the iconic aircraft from Star Wars. According to a paper published Tuesday in The Astrophysical Journal, the galaxy is active, meaning all of its stars are not capable of providing the amount of light emitted by the galaxy on their own.

Mystery of the dimming of massive star Betelgeuse explained
Astronomers have determined the cause of the dramatic dimming observed last year and earlier this year of one of the brightest stars in the night sky, a colossus called Betelgeuse that appears to be on its way toward a violent death. Based on Hubble Space Telescope observations, scientists said they believe Betelgeuse ejected a huge hot, dense cloud of material into space that cooled to form dust, shielding the star’s light and making it appear dimmer from the perspective of viewers on Earth.

Mysterious 'fast radio burst' detected closer to Earth than ever before
Thirty thousand years ago, a dead star on the other side of the Milky Way belched out a powerful mixture of radio and X-ray energy. On April 28, 2020, that belch swept over Earth, triggering alarms at observatories around the world. The signal was there and gone in half a second, but that's all scientists needed to confirm they had detected something remarkable: the first ever "fast radio burst" (FRB) to emanate from a known star within the Milky Way, according to a study published July 27 in The Astrophysical Journal Letters.

Why it’s time to take alternatives to dark matter seriously
In 1969, the American astronomer Vera Rubin puzzled over her observations of the sprawling Andromeda Galaxy, the Milky Way’s biggest neighbour. As she mapped out the rotating spiral arms of stars through spectra carefully measured at the Kitt Peak National Observatory and the Lowell Observatory, both in Arizona, she noticed something strange: the stars in the galaxy’s outskirts seemed to be orbiting far too fast. So fast that she’d expect them to escape Andromeda and fling out into the heavens beyond. Yet the whirling stars stayed in place.
