I wonder many times why exploring the universe is so important and why large hands like NASA and ISRO spend a huge amount of money on sending rockets into space. Later, I came to know that to survive mankind for a large scale of time being only depending on earth is not very safe, so mankind is trying to make life multiplanetary. Due to continuous reactions in the sun, the size of the sun keeps increasing for many years and after some billion years, approximately 7.2 billion years, the sun will add earth into itself. So being on a single planet wasn't safe enough, but from the latest information from astronauts is that before that 7.2 billion years a nearby galaxy called aroma will collapse to our milky way galaxy. The distance of our galaxy to travel edge of galaxy is approximately 20000 light years (light years =distance travelled by a light in one year). If we look into present technology, there aren't pleasant energy sources like petrol, helium to travel such a large distan...

Writing a diary took place today for me, not just for life memory, but also to use the app for usage of store reality ideas. It's started curious for me after knowing things get better by making things smaller. At initial age of computer it was known that computer was in larger size and the microchip consisted only 5 to 6 transistors at that time, but later the no. Of transistors per 1 microchip got increasing. In 2000 year , 2000 transistors fitted into 1 microchip, and now a modern smartphone from Apple company has 7 trillion transistors in microchip. By this analysis, I clearly understand that technology has advanced by making things smaller. It would be great work if something was done like this. And also today it's known that a technology called nano technology is similar to this. Curing of cancer by nano technology is mind blowing. The impact it has on the medical field would be great. The scientist who doesn't even have the least knowledge of medicine can save many l...

The technology received a vote of confidence from investors today, as 2 -year-old stealth startup Quantum Brilliance raised a nearly $10m seed funding round from a consortium of investors led by Main Sequence Ventures and the founders of QxBranch, the Australian quantum services company acquired by Rigetti. The funding will speed the commercialisation of the technology, which Andrew Horsley, CEO of the Australian-German startup, says could dramatically change the way quantum computing can be used. “It is simplifying the quantum computer and turning it into something that can sit in an ordinary server rack next to classical computers. Most quantum computers are giant mainframes; these will eventually be small enough to be embedded in mobile devices,” Horsley told Sifted. “The miniaturisation potential is huge.” So is the volume of quantum computers that could be created using this technique. “We are thinking about volumes in millions.” “We are thinking about volumes in millions, not the...

Measuring a black hole’s mass isn’t easy. A new technique could change that Flickering in the gas and dust of the accretion disk of a black hole provides hints of its mass Astronomers have figured out how to use the disk of hot gas and dust around some black holes (like the one shown in this artist’s illustration) to measure the black hole’s mass. MARK A. GARLICK, SIMONS FOUNDATION Share this: Email Facebook Twitter Pocket Reddit Print By  Lisa Grossman AUGUST 12, 2021 AT 2:00 PM An actively feeding black hole surrounds itself with a disk of hot gas and dust that flickers like a campfire. Astronomers have now found that monitoring changes in those flickers can reveal something that is notoriously hard to measure: the behemoth’s heft. “It’s a new way to weigh black holes,” says astronomer Colin Burke of the University of Illinois at Urbana-Champaign. What’s more, the method could be used on  any astrophysical object with an accretion disk , and may even help find el...

How Bell’s Theorem Proved ‘Spooky Action at a Distance’ Is Real By BEN BRUBAKER July 20, 2021 The root of today’s quantum revolution was John Stewart Bell’s 1964 theorem showing that quantum mechanics really permits instantaneous connections between far-apart locations 103 READ LATER Samuel Velasco/Quanta Magazine We take for granted that an event in one part of the world cannot instantly affect what happens far away. This principle, which physicists call locality, was long regarded as a bedrock assumption about the laws of physics. So when Albert Einstein and two colleagues showed in 1935 that quantum mechanics permits “spooky action at a distance,” as Einstein put it, this feature of the theory seemed highly suspect. Physicists wondered whether quantum mechanics was missing something. Then in 1964, with the stroke of a pen, the Northern Irish physicist John Stewart Bell demoted locality from a cherished principle to a testable hypothesis. Bell  proved  that quant...

Vaccines Are Pushing Pathogens to Evolve IMMUNOLOGY Vaccines Are Pushing Pathogens to Evolve By MELINDA WENNER MOYER May 10, 2018 Just as antibiotics breed resistance in bacteria, vaccines can incite changes that enable diseases to escape their control. Researchers are working to head off the evolution of new threats. 10 READ LATER Matthew J. Jones, a research assistant at Pennsylvania State University, takes a sample of dust collected from a chicken farm to test it for signs of the virus that causes Marek’s disease, an infection common among poultry. Some evidence suggests that the virus that causes the disease is becoming immune to yet another version of the vaccine that controls it. Sasha Maslov  for Quanta Magazine Andrew Read  became a scientist so he could spend more time in nature, but he never imagined that would mean a commercial chicken farm. Read, a disease ecologist who directs the Pennsylvania State University Center for Infectious Disea...
