I found this on NewsBreak: Dark energy could be getting weaker, suggesting the universe will end in a ‘Big Crunch’
The first year of Dark Energy Spectroscopic Instrument (DESI) data seems to show that dark energy is weakening over time, possibly the biggest cosmological discovery for 25 years.

I found this on NewsBreak: Most massive stellar black hole in the Milky Way discovered ‘extremely close’ to Earth.
Astronomers have found the most massive stellar-mass black hole ever discovered in our galaxy — and it’s lurking “extremely close” to Earth, according to new research.
The black hole, named Gaia BH3, is 33 times more massive than our sun. Cygnus X-1, the next-biggest stellar black hole known in our galaxy, weighs only 21 solar masses. The newfound black hole is located roughly 2,000 light-years away in the constellation Aquila, making it the second-closest known black hole to Earth.
A number of high-profile astronomers are set to convene at London’s Royal Society to question some of the most fundamental aspects of our understanding of the universe.
As The Guardian reports, the luminaries of cosmology will be re-examining some basic assumptions about the universe — right down to the over-a-century-old theory that it’s expanding at a constant rate.
“We are, in cosmology, using a model that was first formulated in 1922,” coorganizer and Oxford cosmologist Subir Sarkar told the newspaper, in an apparent reference to the year Russian astronomer Alexander Friedmann outlined the possibility of cosmic expansion based on Einstein’s general theory of relativity.
Astronomers have identified the most massive stellar black hole yet discovered in the Milky Way galaxy. This black hole was spotted in data from the European Space Agency’s Gaia mission because it imposes an odd ‘wobbling’ motion on the companion star orbiting it. Data from the European Southern Observatory’s Very Large Telescope (ESO’s VLT) and other ground-based observatories were used to verify the mass of the black hole, putting it at an impressive 33 times that of the sun.
Gateways between stars, wormholes through the fabric of reality, but could these be real, and if so, what would the civilizations using them be like?

Hyperjumps, wormholes, and warp drives sound like science fiction, but they’re actually based on real science! Though I believe out of the three, warp drives are the most plausible. The math seems to agree. Today I want to tell you about a new way of analysing and visualizing warp drives.
MYSTERIOUS signals are being detected coming from a star that has been radio silent for over a decade, according to scientists.
The radio signals are very powerful and their sudden appearance has baffled experts.
According to Live Science, the strange star is a magnetar that suddenly became very active again in 2018.
The brightest burst of light ever recorded was caused by a supernova, but that prompts new questions.
Astronomers detect long-sought compact object within the remnant of Supernova 1987A In February 1987, the closest supernova to Earth in almost 400 years exploded onto the scene. Designated Supernova 1987A (SN 1987A), it resulted from the death of a massive star in the Large Magellanic Cloud, a dwarf galaxy 160,000 light-years away. In the decades since, its remnant has been studied by telescopes at all wavelengths of light from X-rays to radio. Yet despite all the scrutiny, one mystery has remained.
