Scientists Discover the Nearest Black Hole to Our Solar System Ever Found

Posted by in categories: computing, cosmology, physics

Astronomers have recently found the nearest known black hole to our solar system. According to scientists, the black hole is 1,570 lightyears away and ten times larger than our sun.

Known as Gaia BH1, the research was led by Harvard Society Fellow astrophysicist Kareem El-Badry, with the Harvard-Smithsonian Center for Astrophysics (CfA) and the Max Planck Institute for Astronomy (MPIA).

In addition, El-Badry worked with researchers from CfA, MPIA, Caltech, UC Berkeley, the Flatiron Institute’s Center for Computational Astrophysics (CCA), the Weizmann Institute of Science, the Observatoire de Paris, MIT’s Kavli Institute for Astrophysics and Space Research, and other universities.

‘Immortality Is My Goal’: 11-Year-Old Boy Gets Bachelor’s Degree In Physics

Posted by in categories: life extension, physics

Eleven-year-old Simons only took a year to complete his bachelor’s degree, which usually takes at least three years.

In a conversation with the Dutch daily De Telegraaf, Simons said that, “I don’t really care if I’m the youngest.” “It’s all about getting knowledge for me.”

“This is the first puzzle piece in my goal of replacing body parts with mechanical parts,” Simons said.

MIT Contributes to Success of Historic Fusion Ignition Experiment

Posted by in categories: energy, physics

MIT students are part of the large team that achieved fusion ignition for the first time in a laboratory. Researchers around the world have been engaged in attempts to achieve fusion ignition in a laboratory for more than half a century. It is a grand challenge of the 21st century. An approach called inertial confinement fusion (ICF), which uses lasers to implode a pellet of fuel in a quest for ignition, has been the focus of the High-Energy-Density Physics (HEDP) group at MIT’s Plasma Science and Fusion Center. This group, including nine former and current MIT students, was crucial to a historic ICF ignition experiment performed in 2021. The results were published this year on the anniversary of that success.

Released: James Webb Image We Were All Waiting For

Posted by in categories: physics, space

The James Webb Space Telescope has released stunning new images of the Orion nebula, a star-forming region lying about 1,300 light years away in the Orion constellation. The images are overflowing with details and are a significant improvement over the Hubble and the Spitzer images of the same. Structures down to the size of the solar system can be seen in them.

The details of the new Webb images will enable astronomers studying stellar astrophysics to understand star formation in detail. Star formation is still not fully understood, and several questions remain unanswered.

Researchers May Have Actually Managed To Hear The Background ‘Hum’ Of The Universe

Posted by in categories: physics, space

I know, it might sound a bit out there, but it seems we’re able to hear more than you’d expect. Researchers have managed to hear something that they believe is the ‘hum’ of the universe and well, the concept in itself is mind-blowing.

While this ‘hum’ isn’t exactly what you’d expect, it is quite interesting to learn about. You see, because there is no air in space it’s not actually a sound at all but rather more or less something quite different. This finding overall comes from astronomers at the North American Nanohertz Observatory for Gravitational Waves also known as ‘NANOGrav.’ Overall this hum could really help us better understand the history of the universe in time as we further research it.

NANOGrav wrote as follows on this topic:

Do the laws of physics and neuroscience disprove free will?

Posted by in categories: neuroscience, physics

Many have argued that free will is in illusion, but science does not support that. We should be grateful that free will exists.

China to produce clean energy with nuclear fusion by 2028, top weapons expert claims

Posted by in categories: engineering, nuclear energy, physics

So far, Chinese scientists have achieved a reaction running at a slightly cooler 70 million degrees celsius for more than 17 minutes.

China aspires to produce unlimited clean energy through nuclear fusion by 2028.

The “world’s largest” pulsed-power plant will be built in Chengdu, Sichuan province, according to Professor Peng Xianjue of the Chinese Academy of Engineering Physics, The Independent reported on Wednesday.

Does Cosmic Fine-Tuning Demand Explanation? | Episode 1208 | Closer To Truth

Posted by in categories: alien life, physics

The universe works for us because of deep physical laws. But if the values of these laws change much, then all we see and know could not exist. If small changes to the laws of physics would make life impossible, does fine-tuning require an explanation? Featuring interviews with Bernard Carr, David Deutsch, Richard Swinburne, Rodney Holder, and Christopher Isham.

Season 12, Episode 8 — #CloserToTruth.

Scientists think they have found a solution to one of the oldest problems in the universe

Posted by in categories: cosmology, physics

It’s one of the oldest problems in the universe: Since matter and antimatter annihilate each other on contact, and both forms of matter existed at the moment of the big bang, why is there a universe made primarily of matter rather than nothing at all? Where did all the antimatter go?

“The fact that our current-day universe is dominated by matter remains among the most perplexing, longstanding mysteries in modern physics,” University of California, Riverside professor of physics and astronomy Yanou Cui said in a statement shared this week. “A subtle imbalance or asymmetry between matter and antimatter in the early universe is required to achieve today’s matter dominance but cannot be realized within the known framework of fundamental physics.”

There are theories that might answer that question, but they are extremely to difficult to test using laboratory experiments. Now, in a new paper published Thursday in the journal Physical Review Letters, Dr Cui and her co-author, Zhong-Zhi Xianyu, assistant professor of physics at Tsinghua University, China, explain they may have found a work around using the afterglow of the big bang itself to run the experiment.
