SpaceX aborts launch with initial satellites for Space Development Agency

Posted by in categories: internet, satellites

It is interesting to watch SpaceX continue to massively expand, with the goal of going from 61 launches last year to 100 launches this year.

SpaceX’s old record for a month was 7 launches, but in March they completed 8 launches, and almost did 9 but their latest launch had technical difficulties, and the closest they got to launch during the past two days was an abort with 2 seconds to go. They will try a 3rd time to launch this rocket tomorrow.

Is Our Universe a Hologram? Physicists Debate Famous Idea on Its 25th Anniversary

AdS/CFT Proves Its Usefulness

One of the first uses of AdS/CFT had to do with understanding black holes. Theoreticians had long been grappling with a paradox thrown up by these enigmatic cosmic objects. In the 1970s Stephen Hawking showed that black holes emit thermal radiation, in the form of particles, because of quantum mechanical effects near the event horizon. In the absence of infalling matter, this “Hawking” radiation would cause a black hole to eventually evaporate. This idea posed a problem. What happens to the information contained in the matter that formed the black hole? Is the information lost forever? Such a loss would go against the laws of quantum mechanics, which say that information cannot be destroyed.

Great Mysteries of Physics 4: does objective reality exist?

Posted by in categories: cosmology, particle physics, quantum physics

That means that these two people will say that the state of reality is different – they’d have different facts about where the particle is.

There are may other oddities about quantum mechanics, too. Particles can be entangled in a way that enables them to somehow share information instantaneously even if they’re light years apart, for example. This challenges another common intution: that objects need a physical mediator to interact.

Physicists have therefore long debated how to interpret quantum mechanics. Is it a true and objective description of reality? If so, what happens to all the possible outcomes that we don’t measure? The many worlds interpretation argues they do happen – but in parallel universes.

Multiverse or Cyclic Universe? Alan Guth vs Roger Penrose

Posted by in categories: cosmology, entertainment

Do we live in a multiverses or a cyclic universe? Most cosmologists today accept the universe underwent a very rapid period of expansion called inflation. But inflation seems to lead to an infinite multiverse. Not everyone is happy with this multiverse ; and some cosmologists have sought alternatives to inflation. These alternative schemes are often cyclic. The chief proponent of one such cyclic model is 2020 Nobel Prize Winner Sir Roger Penrose. In this video the father of inflation Alan Guth and Sir Roger discuss the pros and cons of the inflationary multiverse versus Sir Roger’s Conformal Cyclic Universe.
We highly recommend watching our film on eternal inflation with Alan Guth and colleagues.

and our film on CCC with Roger Penrose and colleagues.
and other films in our Before the Big Bang Series which features Stephen Hawking, Alex Vilenkin and others.

Study finds centenarians possess unique immunity that helps them achieve exceptional longevity

Posted by in categories: biotech/medical, life extension, policy

There are approximately 30 trillion cells in a human body and our health is predicated on them properly interacting with and supporting each other, with the immune system playing a particularly pivotal role. One of the defining characteristics of aging is a decline in the proper functioning of our immune system. Centenarians, a rare population of individuals who reach 100 years or more, experience delays in aging-related diseases and mortality which suggests their immune systems remain functional into extreme old age.

Led by researchers from Boston University Chobanian & Avedisian School of Medicine and Tufts Medical Center, a new study finds harbor distinct immune cell type composition and activity and possess highly functional immune systems that have successfully adapted to a history of sickness allowing for exceptional longevity. These may help identify important mechanisms to recover from disease and promote longevity.

“Our data support the hypothesis that centenarians have protective factors that enable to recover from disease and reach extreme old ages,” said lead author Tanya Karagiannis, Ph.D., senior bioinformatician, Center for Quantitative Methods and Data Science, Institute for Clinical Research and Health Policy Studies at Tufts Medical Center.

D3dcompiler_47.dll: If AV raises an alerts about this Microsoft signed dll file, you are in trouble

Posted by in categories: cybercrime/malcode, encryption, internet

Threat actors used a well-liked piece of corporate communication software from 3CX, according to security experts. In particular, reports state that a desktop client for the 3CX VoIP (Voice over Internet Protocol) service was used to specifically target 3CX’s clients.

It is believed that the attack is a multi-part process, with the first stage using a hacked version of the 3CX desktop application. Although the.exe file and the MSI package have the same name, preliminary research indicates that the MSI package is the one that may include DLLs that have been maliciously modified.
