Astronomers can now predict an oncoming supernova just a few years in advance

Posted by in category: cosmology

We’re looking at you, Betelgeuse.

A team of astronomers believes they have found an effective method for predicting a supernova, a report from Space.com reveals. While stars do expand to massive sizes and become red giants before their demise, we have had no way of knowing how long it will take for a red giant to go supernova. It could take hundreds of thousands, if not millions, of years.

All of that has just changed though, thanks to a team of astronomers that has devised a method for spotting stars that are likely to supernova within only a few years — a tiny fraction of time in the context of astronomy.

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.

Does modern cosmology prove the existence of God?

Posted by in category: cosmology

The Kalam cosmological argument asserts that everything that exists has a cause, and what caused the Universe? It’s got to be God.

What are black holes?

Posted by in category: cosmology

They’re among the most interesting astronomical bodies but also one of the most misunderstood. In this video, Fermilab’s Don Lincoln debunks some common misconceptions about black holes and also explains some important truths.

Leonard Susskind Marrying Quantum Physics & General Relativity

Posted by in categories: cosmology, quantum physics

American physicist, professor of theoretical physics at Stanford University, and founding director of the Stanford Institute for Theoretical Physics, Leonard Susskind, explains black holes, quantum physics, general relativity and how they are intertwined.

Knowing how the laws of physics behave at the extremes of space and time, near a black hole, is an important piece of the puzzle we must obtain if we are to understand how the universe works. Leonard Susskind explains how general relativity and quantum mechanics are related.

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.”
