The Big Bang may have not been alone.

The Big Bang may not have been alone. The appearance of all the particles and radiation in the universe may have been joined by another Big Bang that flooded our universe with dark matter particles. And we may be able to detect it.

In the standard cosmological picture, the early universe was a very exotic place. Perhaps the most momentous thing to happen in our cosmos was the event of inflation, which at very early times after the Big Bang, sent our universe into a period of extremely rapid expansion. When inflation ended, the exotic quantum fields that drove that event decayed, transforming themselves into the flood of particles and radiation that remains today.

Dr. Emily Rice, an Associate Professor of Astrophysics at the Macaulay Honors College of CUNY and resident research associate in the Department of Astrophysics at the American Museum of Natural History (AMNH), is one of the keynote speakers at the TEDxCUNY conference to be hosted on March 10, 2023.

Dr. Rice is extremely involved in the scientific community through her role as a researcher and professor. Dr. Rice co-founded the research group Brown Dwarfs in New York City (BDNYC) with Dr. Kelle Cruz from CUNY Hunter College and Dr. Jackie Faherty from AMNH. Brown Dwarfs are objects that have masses between giant exoplanets and low mass stars. Dr. Rice explained there was a lot about Brown Dwarfs that scientists were yet to explore and understand.

“The three of us started this research group following a small project we had collaborated on,” Dr. Rice said. In 2010, Dr. Cruz had started their work with Hunter College, Dr. Rice was wrapping up her postdoctoral work, and Dr. Faherty was finishing up graduate school. “We all happened to be in New York City at the time, and we were all working with Brown Dwarfs, so we decided to create a research group focused on these substellar objects,” Dr. Rice remarked.

A green bullet train capable of touching 200 miles per hour

The proposed 218-mile high-speed network will connect Las Vegas and Southern California with technology that allows it to maintain a cruising speed of 200 miles per hour (321 km/h). This means the travel time between the cities will be just over an hour. In comparison, a journey by car takes over four hours.

The expenditure on the project is expected to provide a much-needed boost to the economy, including the creation of nearly 35,000 jobs during the construction phase and around 10,000 permanent jobs. According to Brightline, the fully electric, emission-free system will be one of the greenest forms of transportation in the U.S., removing 3 million cars and 400,000 tons of CO2 each year.

You’re going to have strong feelings about this redesign.

Gustav Söderström has worked at Spotify for a long time; his first big project was leading the launch of its mobile app back in 2009. That makes him the perfect company leader to talk to about Spotify’s recent redesign, which introduces a visual, TikTok-like feed for discovering new content on the app’s homepage. As his boss, CEO Daniel Ek, put it last week, it’s the biggest change Spotify has undergone since we introduced mobile.

Spotify is launching a feed that will help you discover new artists, podcasts, and audiobooks.

The news comes after 13 percent of the company was cut in November. ‘This will be tough and there’s no way around that,’ CEO Mark Zuckerberg told employees.

Meta will lay off an additional 10,000 employees through multiple rounds of cuts over the coming two months, close hiring for 5,000 open roles, and cancel more low-priority projects, CEO Mark Zuckerberg announced on Tuesday. These cuts come just four months after he laid off 11,000 employees, or 13 percent of the company, last November.

Meta plans to cut its workforce by another 10,000 people and withdraw around 5,000 open roles that it had yet to fill, company co-founder and CEO Mark Zuckerberg said Tuesday, confirming recent rumors that another round of layoffs was imminent.

Zuckerberg also said that the company will cancel “lower priority projects,” adding that he “underestimated the indirect costs” associated with these initiatives.

OpenAI has released a powerful new image-and text-understanding AI model, GPT-4, that the company calls “the latest milestone in its effort in scaling up deep learning.”

GPT-4 is available today to OpenAI’s paying users via ChatGPT Plus (with a usage cap), and developers can sign up on a waitlist to access the API.

Pricing is $0.03 per 1,000 “prompt” tokens (about 750 words) and $0.06 per 1,000 “completion” tokens (again, about 750 words). Tokens represent raw text; for example, the word “fantastic” would be split into the tokens “fan,” “tas” and “tic.” Prompt tokens are the parts of words fed into GPT-4 while completion tokens are the content generated by GPT-4.
