Loop quantum gravity theory offers glimpse beyond the event horizon

Posted by in categories: cosmology, quantum physics

In principle, nothing that enters a black hole can leave the black hole. This has considerably complicated the study of these mysterious bodies, which generations of physicists have debated since 1916, when their existence was hypothesized as a direct consequence of Einstein’s Theory of Relativity. There is, however, some consensus in the scientific community regarding black hole entropy—a measure of the inner disorder of a physical system—because its absence would violate the second law of thermodynamics. In particular, Jacob Bekenstein and Stephen Hawking have suggested that the entropy of a black hole is proportional to its area, rather than its volume, as would be more intuitive. This assumption also gives rise to the “holography” hypothesis of black holes, which (very roughly) suggests that what appears to be three-dimensional might, in fact, be an image projected onto a distant two-dimensional cosmic horizon, just like a hologram, which, despite being a two-dimensional image, appears to be three-dimensional.

As we cannot see beyond the event horizon (the outer boundary of the back hole), the internal microstates that define its entropy are inaccessible. So how is it possible to calculate this measure? The theoretical approach adopted by Hawking and Bekenstein is semiclassical (a sort of hybrid between classical physics and quantum mechanics) and introduces the possibility (or necessity) of adopting a quantum gravity approach in these studies in order to obtain a more fundamental comprehension of the physics of .

Planck’s length is the (tiny) dimension at which space-time stops being continuous as we see it, and takes on a discrete graininess made up of quanta, the “atoms” of space-time. The universe at this dimension is described by quantum mechanics. Quantum gravity is the field of enquiry that investigates gravity in the framework of . Gravity has been very well described within classical physics, but it is unclear how it behaves at the Planck scale.

Transhumanist visionary Zoltan Istvan believes Donald Trump, Hillary Clinton need him to win

Posted by in categories: geopolitics, life extension, transhumanism

Here’s an article on transhumanism in Oregon’s largest paper, The Oregonian: It highlights something I’m trying to create: the impact of a “longevity vote” in the elections to make a difference for the length of people’s lifespans.


Zoltan Istvan is ready to encourage his supporters to vote for either Hillary Clinton or Donald Trump in November — if one of the major-party candidates agrees to put him to work in the White House.

And they’d better take his offer seriously, because he figures he just might be able to tip the election whichever way he wants.

These ‘stealth motorcycles’ DARPA commissioned could run on nearly any fuel

Posted by in categories: energy, transportation

Say this for DARPA, it’s not shy about picking ominous names for its projects. Or, in this case, not worried when the partners it works with choose them. Pictured above: the “Nightmare” a “stealth bike” developed by LSA Autonomy for DARPA that has just been moved on to the second stage of development, according to Defense One. DARPA commissioned both it and another bike from Logos Technologies to meet some specific goals: run quietly on electric power, but also run on whatever fuel a soldier in the field.

Alex Dzwill of Logos told Defense One that its bike, the SilentHawk, could run on anything from gasoline to propane to jet fuel:” It will figure it out.”

Apple’s flirtation with buying HBO parent hints at content ambitions

Posted by in categories: augmented reality, business, media & arts, mobile phones, singularity, virtual reality

While Amazon, Google, and Microsoft are moving forward with nextgen technologies such as VR & AR, QC, bio & nano technologies, etc used to advance areas such as Singularity and longevity.; Apples going bigger in the entertainment and media space.


Even if Apple never made an actual move to buy Time Warner, a tentative approach shows that the iPhone maker is serious about getting into media content.

Eddy Cue, who’s in charge of iTunes and Apple Music, brought up the idea of a possible deal with Time Warner corporate strategy head Olaf Olafsson in a meeting late last year, according to a person familiar with the situation. While the two never started negotiations, Time Warner, which owns HBO and the Warner Brothers studio, is on the top of the list of media companies Apple would buy should it eventually commit to the content business, the person said.
