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.

Potentially habitable “super-Earth” discovered 100 light-years away

Posted by in categories: alien life, physics

An international team of scientists announced on Wednesday that they have discovered two new “super-Earth” planets just 100 light-years away. Both of them are significantly larger than our own planet — and one of them may even be suitable for life.

Super-Earths are a unique class of exoplanet in the solar system that are more massive than our planet but lighter than the ice giants, according to NASA. They are made by some combination of gas and rock and can get up to 10 times the size of Earth’s mass.

The findings, discovered with NASA’s Transiting Exoplanet Survey Satellite and the University of Liège’s Search for Habitable Planets Eclipsing Ultra-Cool Stars (SPECULOOS), will be published in the journal Astronomy and Astrophysics.

YouTube: Are we rethinking the Big Bang?

Posted by in categories: cosmology, physics

On this explainer, Neil deGrasse Tyson and comic co-host Chuck Nice break down Big Bang skepticism and what’s going on at the frontier of astrophysics.

What are the core tenets of the Big Bang Theory? We explore the frontier of scientific research and what ideas are being contested. We also walk through the scientific process and experimentations. Could the Big Bang just be a small piece of a bigger theory? Learn about Vulcan, the hypothetical planet pulling on Mercury that was invented to save Newton’s Laws. When Einstein’s relativity came along, why didn’t Newtonian physics go away?

Voxengo plugin developer says he’s broken into “some ‘backdoor’ in mathematics itself” that proves that the universe has a ‘creator’

Posted by in categories: cosmology, mathematics, physics

Vaneev posits that: “‘intelligent impulses’ or even ‘human mind’ itself (because a musician can understand these impulses) existed long before the ‘Big Bang’ happened. This discovery is probably both the greatest discovery in the history of mankind, and the worst discovery (for many) as it poses very unnerving questions that touch religious grounds.”

The Voxengo developer sums up his findings as follows: “These results of 1-bit PRVHASH say the following: if abstract mathematics contains not just a system of rules for manipulating numbers, but also a freely-defined fixed information that is also ‘readable’ by a person, then mathematics does not just ‘exist’, but ‘it was formed’, because mathematics does not evolve (beside human discovery of new rules and patterns). And since physics cannot be formulated without such mathematics, and physical processes clearly obey these mathematical rules, it means that a Creator/Higher Intelligence/God exists in relation to the Universe. For the author personally, everything is proven here.”

Vaneev says that he wanted to “share my astonishment and satisfaction with the results of this work that took much more of my time than I had wished for,” but that you don’t need to concern yourself too much with his findings if you don’t want to.”
