The Universe in a lab: Testing alternate cosmology using a cloud of atoms

Posted by in categories: cosmology, information science, particle physics, quantum physics, space travel

In the basement of Kirchhoff-Institut für Physik in Germany, researchers have been simulating the Universe as it might have existed shortly after the Big Bang. They have created a tabletop quantum field simulation that involves using magnets and lasers to control a sample of potassium-39 atoms that is held close to absolute zero. They then use equations to translate the results at this small scale to explore possible features of the early Universe.

The work done so far shows that it’s possible to simulate a Universe with a different curvature. In a positively curved universe, if you travel in any direction in a straight line, you will come back to where you started. In a negatively curved universe, space is bent in a saddle shape. The Universe is currently flat or nearly flat, according to Marius Sparn, a PhD student at Kirchhoff-Institut für Physik. But at the beginning of its existence, it might have been more positively or negatively curved.

Amazon Taps SpaceX For Satellite Launch Despite Jeff Bezos’ Rocket Company: Elon Musk Says It Will Be ‘Fair And Square’

Posted by in categories: Elon Musk, internet, satellites

Billionaire CEO Elon Musk on Friday said that his rocket manufacturing company SpaceX launched the satellite systems of its rivals without favoring their own.

The CEO took to X to clarify the same after SpaceX entered into a contract to launch Amazon.com Inc’s AMZN Kuiper satellites, aimed at providing satellite internet along the lines of SpaceX’s Starlink.

What Happened: Under the newly announced contract, SpaceX’s Falcon 9 rocket will launch thrice to deliver Kuiper satellites to low-Earth orbit starting mid-2025. Project Kuiper is a project by the e-commerce giant aimed at providing broadband with the help of a network of satellites in low-Earth orbit like Starlink.

‘The great wealth transfer’ is here: Billionaires set to give trillions to their kids

Posted by in category: business

In recent months, the world’s new billionaires made more of their fortunes from inheritance than from entrepreneurship, according to the UBS Billionaire Ambitions Report.

It marked the first time in the nine-year history of the report that newly minted billionaires accumulated more wealth from inheritance than starting a business.

Fifty-three heirs inherited a total of $150.8 billion in the 12 months ending in April, exceeding the total of $140.7 billion accumulated by 84 new self-made billionaires, according to the Swiss bank’s report. The shift is likely to continue: The report said more than 1,000 billionaires are expected to pass $5.2 trillion to their children over the next 20 or 30 years.

Amazon taps SpaceX’s Falcon 9 rocket to help launch Kuiper satellites

Posted by in categories: business, Elon Musk, internet, satellites

Dec 1 (Reuters) — Amazon (AMZN.O) on Friday said it booked three Falcon 9 launches with Elon Musk’s SpaceX to help deploy the ecommerce giant’s Project Kuiper satellite network, tapping a rival in the satellite internet business for its multi-billion dollar launch campaign.

Amazon aims to build Kuiper as a constellation of 3,236 satellites in low Earth orbit to beam broadband internet globally and compete with SpaceX’s Starlink network, which already has some 5,000 satellites providing nearly global coverage.

Amazon, which vowed in 2019 to invest $10 billion into the project, will put an unspecified number of Kuiper satellites on three Falcon 9 rockets from SpaceX beginning in mid-2025, the company said Friday.

Spatiotemporal control of RNA metabolism and CRISPR–Cas functions using engineered photoswitchable RNA-binding proteins

Posted by in categories: biotech/medical, engineering

This protocol for the spatiotemporal control of RNA activity uses LicV, a synthetic, photoswitchable RNA-binding protein (RBP) that can bind to a specific RNA sequence in response to blue light irradiation, and provides an efficient and generalizable strategy for engineering photoswitchable RBPs.
