Traditionally, we’ve done science by observing nature in person or setting up experiments in the lab. Now, a relatively new scientific technique is proving a powerful tool—simulating nature on supercomputers.
A few years ago, Caltech astrophysicists released a supercomputer simulation of a supergiant star’s core collapsing just prior to going supernova. Apart from a stunning visual, simulations like this hinted that Type II supernova explosions were asymmetrical—a guess just recently backed by empirical observation.

Harnessing “Black Holes”: The Large Hadron Collider – Ultimate Weapon of Mass Destruction
Why the LHC must be shut down
What would you have done to stop catastrophic events if you knew in advance what you know now.
We have the moral obligation to take action in every way we can.
The future is in our hands. The stakes are the highest they have ever been. The Large Hadron Collider developed by the European Centre for Nuclear Research (CERN) is a dangerous instrument. The start-up April 5 has initiated a more reckless use of LHC’s capabilities.

Title: Super Physics for Super Technologies
Sub Title: Replacing Bohr, Heisenberg, Schrödinger & Einstein
Author: Benjamin T Solomon
Paperback: 154 pages
Publisher: Propulsion Physics, Inc. (March 19, 2015)
Reviewer’s comments: “Benjamin is the second researcher I have met who has tried to consider a nonsingular cosmology. The first was Christi Stoica, which I met in 2010″.
Andrew Beckwith PhD
The Objective: This book, Super Physics for Super Technologies, proposes that a new physics exists. The findings are based on 16 years of extensive numerical modeling with empirical data, and therefore, both testable and irrefutable.

I have two examples to offer: c–global and cryodynamics.
c–global is based on overcoming an oversight Einstein had made in December of 1907. He assumed c to be reduced in proportion to his newly discovered gravitational redshift valid downstairs, while in reality an optically masked size increase occurs down there. The newly reconstituted c–global rules out cosmic expansion.
Cryodynamics is the new sister discipline to thermodynamics. It governs gases made up from mutually attractive particles. It explains the observed cosmological redshift without expansion.
Although both findings are in the literature for years, it is impossible to evoke any response. This despite the fact that cryodynamics promises limitless free energy. There is no support for its aficionados anywhere.

The Super Bowl isn’t just a football game. It’s an opportunity to discuss physics. Let’s look at some of the interesting physics concepts that go with the game.
Deflategate and Ball Pressure
I don’t know about you, but I’m getting a little weary of the whole “deflategate” thing. In case you missed the controversy, it appears that some of the footballs in the playoff game between the Indianapolis Colts and the New England Patriots had below-acceptable inflation pressure. Now, it’s true that if you put a balloon outside on a cold day, the balloon deflates with the colder temperature. Could something like this have happened to the deflategate balls? The answer is: probably not. If you want more details, Chad Orzel has an excellent piece that looks at the physics of pressurized football. He shows experimentally that a ball in a 50°F football game wouldn’t drop 2 PSI due solely to the temperature change.

The study of consciousness and what makes us individuals is a topic filled with complexities. From a neuroscience perspective, consciousness is derived from a self-model as a unitary structure that shapes our perceptions, decisions and feelings. There is a tendency to jump to the conclusion with this model that mankind is being defined as self-absorbed and only being in it for ourselves in this life. Although that may be partially true, this definition of consciousness doesn’t necessarily address the role of morals and how that is shaped into our being. In the latest addition to The Galactic Public Archives, Dr. Ken Hayworth tackles the philosophical impact that technologies have on our lives.
Our previous two films feature Dr. Hayworth extrapolating about what radical new technologies in neuroscience could eventually produce. In a hypothetical world where mind upload is possible and we could create a perfect replica of ourselves, how would one personally identify? If this copy has the same memories and biological components, our method of understanding consciousness would inevitably shift. But when it comes down it, if we were put in a situation where it would be either you or the replica – it’s natural evolutionary instinct to want to save ourselves even if the other is an exact copy. This notion challenges the idea that our essence is defined by our life experiences because many different people can have identical experiences yet react differently.
Hayworth explains, that although there is an instinct for self-survival, humanity for the most part, has a basic understanding not to cause harm upon others. This is because morals are not being developed in the “hard drive” of your life experiences; instead our morals are tied to the very idea of someone just being a conscious and connected member of this world. Hayworth rationalizes that once we accept our flawed intuition of self, humanity will come to a spiritual understanding that the respect we give to others for simply possessing a reflection of the same kind of consciousness will be the key to us identifying our ultimate interconnectedness.

The ups and downs of Bitcoin as an internet currency may be compared to the eventual demise of Google Glass due to its lack of purpose among consumers. While it does not significantly hold true for bitcoins, which apparently have a more supportive and enthusiastic followers, the path that these two have taken and will take may be substantially similar than we like to admit.
For one, Bitcoin’s staggering price decline in the recent days left some people wondering what road it will eventually take in the near future. Is it only taking a detour or is it bound for a dead end?
In the case of Google Glass, it received much attention during its inception a few years ago. It was even named by Time magazine one of the best innovations of 2012. However, despite the ingenuity behind a supposed-to-be groundbreaking invention, Google Glass lacked a tangible sense, its purpose incoherent.
You need a pocket mirror, a laser pointer and a counter. Then measure both the up-down time (or distance) and the down-up time (or distance). The two are different.
This means, taking light-radar as a reliable measuring device, that the two measured heights are different. As far as I know, the experiment has never been done in spite of its simplicity.
Why is it worth doing? This “V-Lambda” experiment can also be called “WM” experiment, with the two letters printed on top of each other. You then get XXXX. Very regularly, no shifts. That is, upper and lower time intervals interlock even though being different.
You can do the same experiment between earth and a neutron star (provided a mirror can be deposited on its surface). Then the two time intervals that interlock differ by a factor of about 2.
