In a paper published in the Journal of Cosmology and Astroparticle Physics, scientists examined the theoretical and observational cases for a ‘cosmic...
In April 2019, the Event Horizon Telescope (EHT) Collaboration reported the first-ever event-horizon-scale images of a black hole, resolving the central...
In a new paper, astrophysicists from Australian National University present an overview of the thermal history of our Universe and the sequence of objects...
Physicists from the ALPHA Collaboration at CERN’s Antimatter Factory have demonstrated the existence of gravity between antimatter and Earth, reaffirming...
A fundamental consequence of the relativistic picture of expanding space is cosmological time dilation, where events in the distant Universe appear to...
Using data from NSF’s Atacama Cosmology Telescope, astronomers have produced the most detailed map of dark matter distributed across one quarter of the...
In November 2019, the nearby single, isolated white dwarf LAWD 37 aligned closely with a distant background source and caused a so-called microlensing...
This is the first time such an effect, known as precession, has been seen in black holes, where the twisting is 10 billion times faster than in previous...
A new theoretical paper, published in the journal Classical and Quantum Gravity, reignites the debate about the possibility of superluminal (faster-than-light)...
The 2017 observations from the Event Horizon Telescope (EHT) of M87*, a 6.5-billion-solar-mass black hole in the center of the giant elliptical galaxy...
At the center of the Milky Way lurks Sagittarius A*, a supermassive black hole that is four million times the mass of the Sun. Located 26,000 light-years...
In April 2019, the Event Horizon Telescope (EHT) Collaboration released stunning images of the supermassive black hole in Messier 87, a giant elliptical...
High-speed particle jets from gamma-ray bursts may exceed the speed of light in surrounding gas clouds, but do so without violating Einstein’s theory...
One of the fundamental principles of quantum mechanics is quantum superposition, in which a particle exists in two or more states simultaneously. In a...
In a test of Einstein’s theory of general relativity near the supermassive black hole at the center of our Milky Way Galaxy, an international group of...
Loop quantum gravity is a theory that uses quantum mechanics to extend gravitational physics beyond Einstein’s theory of general relativity. Previous...
