What does it mean to ask about the end of the universe? Can the universe even have an end? What would end? In the far, far future, what happens to stars, galaxies, and black holes? What about mass and energy, even space and time? What’s the ‘Big Crunch’ and the ‘Big Rip’? And what if there are multiple universes, will the multiverse ever end?

Its demonstration nuclear power plant is expected to be ready by 2035.

The Experimental Advanced Superconducting Tokamak (EAST), popularly known as China’s “artificial sun”, set a new record on Wednesday by running for 403 seconds in a steady-state high-confinement long plasma operation, Chinese news outlet CGTN

In the early 1900s, Albert Einstein proposed the theory of general relativity, which challenged everything scientists believed they understood about the universe at the time. Over the years, scientists have questioned whether this theory was true. However, a newly created dark matter map finally gives undeniable proof.

We must first look at Einstein’s original theory to fully understand this new development. Before Einstein proposed the theory of general relativity, scientists believed space to be almost featureless and changeless. Further, they thought that time flowed at its own pace, oblivious to clocks that tried to measure it, as Isaac Newton had suggested two centuries earlier.

However, Einstein proposed that both space and time were one force, spacetime, and that matter within this ever-changing stage was controlled by the curving path that gravity dictated. But to create gravity, we needed mass, a force so strong it could literally curve spacetime around it. This is where dark matter comes into play.

— What’s the biggest black hole in the universe?

LISA will consist of a trio of satellites orbiting the sun that will constantly monitor the distances among them. When a gravitational wave comes by, the satellites will detect the telltale signature, like buoys in the ocean recognizing a passing tidal wave.

To search for IMBHs, the astronomers have to hope for a lucky break. If an IMBH in the galactic center happens to capture a wandering dense remnant (like a smaller black hole, a neutron star, or a white dwarf), the process will emit gravitational waves that LISA can potentially detect. Because the IMBH itself will be orbiting around the central supermassive black hole, these gravitational waves will undergo a Doppler shift (like the shifting in frequencies from a passing ambulance) due to the IMBH’s motion.

Some mysteries in science vanish with more accurate measurements, resolving gaps with a puff of new data. And sometimes, a second look simply reinforces the fact you have a mystery on your hands.

It’s the latter in the case of a new study that challenges the Universe’s most fundamental laws of physics.

The Hubble constant is an expression of the speed of Universe’s expansion. Unfortunately, there’s more than one solution for it, depending on how it’s measured.

Astronomers have long debated the source of ULXs, chalking their brightness up to optical illusions. A new study confirms that they’re all that they appear.

Researchers replicated the classic double slit experiment using lasers, but their slits are in time not space.

A magnetic cage keeps the more than 100 million degree Celsius hot plasmas in nuclear fusion devices at a distance from the vessel wall so that they do not melt. Now researchers at the Max Planck Institute for Plasma Physics (IPP) have found a way to significantly reduce this distance. This could make it possible to build smaller and cheaper fusion reactors for energy production. The work was published in the journal Physical Review Letters.

Research by the Atacama Cosmology Telescope collaboration has culminated in a significant breakthrough in understanding the evolution of the universe.

For millennia, humans have been fascinated by the mysteries of the cosmos.

Unlike ancient philosophers imagining the universe’s origins, modern cosmologists use quantitative tools to gain insights into its evolution and structure. Modern cosmology dates back to the early 20th century, with the development of Albert Einstein’s theory of general relativity.
