Something strange has been happening lately. Lots of people are under the impression that images from the James Webb Space Telescope have somehow proven big bang cosmology wrong. This is very stupid and objectively wrong, but it has caused a confusion among even pro-science people, who have been asking me if there is any legitimacy to such claims. I decided a brief debunk was in order, to shine a spotlight on the fraud behind this frenzy, briefly explain why such a claim is so ridiculous, and link to other resources for further information. Enjoy!

We explore the possibility that a new universe can be created by producing a small bubble of false vacuum. The initial bubble is small enough to be produced without an initial singularity, but classically it could not become a universe — instead it would reach a maximum radius and then collapse. We investigate the possibility that quantum effects allow the bubble to tunnel into a larger bubble, of the same mass, which would then classically evolve to become a new universe. The calculation of the tunneling amplitude is attempted, in lowest order semiclassical approximation (in the thin-wall limit), using both a canonical and a functional integral approach. The canonical approach is found to have flaws, attributable to our method of space-time slicing. The functional integral approach leads to a euclidean interpolating solution that is not a manifold. To describe it, we define an object which we call a “pseudomanifold”, and give a prescription to define its action. We conjecture that the tunneling probability to produce a new universe can be approximated using this action, and we show that this leads to a plausible result.

There are calculations which say the universe weighed 10 pounds (4.5 kg) and was no bigger than 10-²⁶ centimeters across before it stretched and sprawled into the great, heaving landscape we know of today. It’s strange to imagine that billions of fiery-tipped stars and billions of husky blue or rosy galaxies could emerge…

Physicists agree, one day it may be possible for a person to create a universe. It won’t happen tomorrow, but the idea is in the works. There’s already one problem with the idea: If a universe is created, physicists say they wouldn’t know how to communicate with it.

The word “network” has become part of our everyday language, in particular since the rise of online social networks. However, human interactions are not only aimed at sociability and fun. Criminals also interact with each other to plan their illicit actions, especially in organized crime.

Motivated by openly available data and publicly released judicial documents from a law-enforcement operation named “Operazione Infinito,” which was conducted in Lombardy between 2007 and 2009 to tackle the ‘Ndrangheta mafia, Bocconi Professor Daniele Durante and his co-authors have developed a new class of statistical models for grouping together with similar connectivity patterns, thus shedding further light on the community structure of criminal organizations.

In fact, within most networks, not all the nodes—that here represent criminals—are connected to each other, and community structures typically arise. The simplest type of community structure is characterized by dense connections within each community, and sparser connections across different communities. This corresponds to the idea that each individual is more likely to connect with the individuals belonging to the same community.

Half of the universe is filled with expansionist alien civilizations, and it’s only a matter of time before they’ll reach us. OK, that sounded a little sensationalist. But it’s also the conclusion of a recent astrophysics paper. Let’s see how they figure this, and whether we should take it seriously.

Summary: Using monoclonal antibodies instead of conventional immunosuppressant drugs preserves stem cells in mouse brains.

A new approach to stem cell therapy that uses antibodies instead of traditional immunosuppressant drugs robustly preserves cells in mouse brains and has potential to fast-track trials in humans, a Michigan Medicine study suggests.

After several years of developing the theoretical ideas, University of Illinois Urbana-Champaign researchers have validated multiple novel predictions about the fundamental mechanism of transport of atoms and molecules (penetrants) in chemically complex molecular and polymer liquid matrices.

The study from Materials Science and Engineering (MatSE) Professor Ken Schweizer and Dr. Baicheng Mei, published recently in Proceedings of the National Academy of Sciences (PNAS), extended the theory and tested it against a large amount of experimental data. MatSE Associate Professor Chris Evans and graduate student Grant Sheridan collaborated on this research by providing additional experimental measurements.

“We developed an advanced, state-of-the art theory to predict how move through complex media, especially in polymer liquids,” Schweizer said. “The theory abstracted what the important features are of the chemically complex molecules and of the polymeric medium that they’re moving through that control their rate of transport.”
