SpaceX CEO Elon Musk recently stated Starship has a roughly 50% chance of reaching orbit on its first try.

SpaceX’s massive next-generation Starship spacecraft could launch on its first orbital test flight within the next few weeks.

“We have taken a vital first step towards harnessing quantum light for practical use.”

Scientists have for the first time shown that they can control and distinguish tiny quantities of interacting photons — or packets of light energy — with high correlation, according to a study published in Nature.

Neutrinos created by LHC went undetected earlier, but FASER changed that and can help us learn more about deep space.

Researchers at the European Organization for Nuclear Research, commonly known as CERN, have detected neutrinos created by the Large Hadron Collider (LHC) experiment for the very first time. These were the highest energy neutrinos that were ever produced in a laboratory setup and are similar to those found in particle showers from deep space.

First detected in 1956, neutrinos are subatomic particles that play a key role in the burning of stars. Every time nuclei of atoms either come together (fusion) or break apart (fission) in the universe, neutrinos are released.

The powerful psychedelic can give you a near-death experience. Here is how it affects your brain on the inside.

Dimethyltryptamine, or DMT, is a powerful psychedelic whose effect on the human brain lasts for only some minutes, but in that short span of time, the user experiences some high-level mental changes.

The researchers examined the brain activity of the participants before, during, and after the DMT test. Here is what they found.

Dark matter does not emit or reflect light, nor does it interact with electromagnetic forces, making it exceptionally difficult to detect. Nevertheless, a research team from The Education University of Hong Kong (EdUHK) has proven that there is a substantial amount of dark matter surrounding black holes. The study results are published in the journal The Astrophysical Journal Letters.

The team selected two nearby (A0620-00 and XTE J1118+480) as research subjects, with both considered as binary systems. That is, each of the black holes has a companion star orbiting it. Based on the orbits of the companion stars, observations indicate that their rates of orbital decay are approximately one millisecond (1ms) per year, which is about 50 times greater than the theoretical estimation of about 0.02ms annually.

To examine whether exists around black holes, the EdUHK team applied the “dark matter dynamical friction model”—a theory widely held in academia—to the two chosen binary systems, through computer simulations. The team found that the fast orbital decay of the companion stars precisely matches the data observed.
