The universe bathes in a sea of light, from the blue-white flickering of young stars to the deep red glow of hydrogen clouds. Beyond the colors seen by human eyes, there are flashes of X-rays and gamma rays, powerful bursts of radio, and the faint, ever-present glow of the cosmic microwave background. The cosmos is filled with colors seen and unseen, ancient and new. But of all these, there was one color that appeared before all the others, the first color of the universe.

The universe began 13.8 billion years ago with the Big Bang. In its earliest moment, it was more dense and hot than it would ever be again. The Big Bang is often visualized as a brilliant flash of light appearing out of a sea of darkness, but that isn’t an accurate picture. The Big Bang didn’t explode into empty space. The Big Bang was an expanding space filled with energy.

At first, temperatures were so high that light didn’t exist. The cosmos had to cool for a fraction of a second before photons could appear. After about 10 seconds, the universe entered the photon epoch. Protons and neutrons had cooled into the nuclei of hydrogen and helium, and space was filled with a plasma of nuclei, electrons and photons. At that time, the temperature of the universe was about 1 billion degrees Kelvin.

Debate needed over research with ‘potential for something to suffer’, neuroscientists say.

The technology scans classrooms at Hangzhou No. 11 High School every 30 seconds and records students’ facial expressions, categorizing them into happy, angry, fearful, confused, or upset. The system also records student actions such as writing, reading, raising a hand, and sleeping at a desk.

The system is analyzing students’ emotions and actions in the classroom to tell whether they are happy, angry, or confused and to monitor whether they are working or sleeping at their desk. The facial-recognition technology has also replaced ID cards and wallets at the library and canteen.

Assumptions: The Case Against Reality

When it comes to scientific theory, (or your personal life) be sure to question everything.

United Parcel Service Inc. is striking a series of drone-delivery agreements with health-care groups as it develops new technology pitched to the growing medical market.

The plans include expanding the use of drones to deliver cargo such as medical samples and supplies on hospital campuses in Utah and elsewhere, and an agreement with CVS Health Corp. to evaluate the use of drones for home delivery of prescriptions and other products, UPS said Monday.

The agreements are the first UPS has announced since the package delivery giant won U.S. regulatory approval to operate commercial drone flights through the company’s Flight Forward subsidiary. The nod from the Federal Aviation Administration paves the way for UPS to scale up operations as it competes with FedEx Corp., Amazon.com Inc. and others vying to develop drone delivery services in the U.S.
