How your immortal consciousness will travel the universe

Posted by in categories: life extension, neuroscience, physics, space

In about 100 years, theoretical physicist Michio Kaku believes we’ll explore the universe as pure consciousness — traveling at the speed of light, looking at asteroids, comets, meteors, and eventually the stars. “All of this within the laws of physics,” he says.

Is panpsychism accurate? Modern physics delivers a reality check

If philosophers don’t try to mesh their long-held views with new scientific insights, then we have a problem. For instance, panpsychism may be due for an update: panprotopsychism, a view that says when fundamental “ingredients of reality” combine, they give rise to conscious experience — and that those fundamental ingredients are “quasimental.”

In this video, NASA’s own Dr. Susan Schneider, who specializes in astrobiology, explains further.

Could a black hole be used as portable gravity device?

Posted by in categories: cosmology, mathematics, physics

I don’t use the term artificial gravity because, the gravity from a black hole is real.

If you have harnessed and are able to control a black hole would you be able to use it as portable gravity device?

I don’t really have the physics and the math to to figure it out. But it would seem that if you are in a low gravity environment, you could place a black hole under the floor, and have gravity. Presumably by changing the distance between the floor and the black hole you could adjust to 1 gravity or partial gravity.

How To Build A Black Hole Laser

You can amplify light by bouncing it between the horizons of a black hole and a white hole. Now physicists have worked out how to build such a device in the lab.

Towards a light driven molecular assembler

Posted by in categories: biological, chemistry, nanotechnology, physics

A team of chemists built the first artificial assembler, which uses light as the energy source. These molecular machines are performing synthesis in a similar way as biological nanomachines. Advantages are fewer side products, enantioselectivity, and shorter synthetic pathways since the mechanosynthesis forces the molecules into a predefined reaction channel.

Chemists usually synthesize molecules using stochastic bond-forming collisions of the reactant molecules in solution. Nature follows a different strategy in biochemical synthesis. The majority of biochemical reactions are driven by machine-type protein complexes that bind and position the reactive molecules for selective transformations. Artificial “molecular assemblers” performing “mechanosynthesis” have been proposed as a new paradigm in chemistry and nanofabrication. A team of chemists at Kiel University (Germany) built the first artificial assembler, that performs synthesis and uses light as the energy source. The system combines selective binding of the reactants, accurate positioning, and active release of the product. The scientists published their findings in the journal Communications Chemistry.

The idea of molecular assemblers, that are able to build molecules, has already been proposed in 1986 by K. Eric Drexler, based on ideas of Richard Feynman, Nobel Laureate in Physics. In his book “Engines of Creation: The Coming Era of Nanotechnology” and follow-up publications Drexler proposes molecular machines capable of positioning reactive molecules with atomic precision and to build larger, more sophisticated structures via mechanosynthesis. If such a molecular nanobot could build any molecule, it could certainly build another copy of itself, i.e. it could self-replicate. These imaginative visions inspired a number of science fiction authors, but also started an intensive scientific controversy.

Physicists Accidentally Discover a Self-Destruct Button for the Entire Universe

I think this type of thinking could also create a force field to protect against collapse. o.o! circa 2016.


Unfortunately, humanity will never see it coming.

Electromagnetic radiation protection shields developed

Posted by in categories: education, nanotechnology, physics

The environment contains electromagnetic radiation and magnetic fields of natural and artificial origin. Even a short electromagnetic pulse is enough to knock any equipment out of operation. Candidate of Sciences (Physics and Mathematics) Aleksey Trukhanov, senior research fellow at the SUSU Nanotechnologies Research and Education Center, is studying electrolytic films to develop electromagnetic and magnetic shields capable of neutralizing this radiation.

“The issue of electromagnetic compatibility of devices is very topical today. One of the most popular methods of equipment protection used around the world is shielding—creating electromagnetic and magnetic shields. But every developer has his own design approaches and secrets, which he naturally wouldn’t share. Suffice it to say that the cost of products with and without protective shielding may differ tenfold and more,” says Trukhanov.

Normally, heavy elements are used as the material for shielding, as they efficiently absorb high-energy radiation. Bismuth is a heavy metal with high density and high number of shell electrons. This makes it analogous to such widely used materials as lead. However, in the ratio of the protection efficiency to mass-size parameters (as well as with consideration to the ecological aspect) bismuth is the best option.

The Chrysalis Conjecture: Solution to the Fermi Paradox?

Posted by in categories: biological, existential risks, physics

It appears that the physics of information holds the key to the solution of the Fermi Paradox — indications are that we most likely live in a “Syntellect Chrysalis” (or our “second womb”) instead of a “cosmic jungle.”

Within the next few decades, we’ll transcend our biology by leaving today’s organic Chrysalis behind, by leaving our second womb, by leaving our cradle, if speaking in tropes.

This particular version of “human universe” is what we “see” from within our dimensional cocoon, it’s a construct of our minds but by no means represents objective reality “out there” including our most advanced models such as M-theory that are only approximations at best.

SpaceX Scores NASA Contract to Launch Black Hole Spacecraft

Posted by in categories: cosmology, physics, space travel

“We cannot directly image what’s going on near objects like black holes and neutron stars, but studying the polarization of X-rays emitted from their surrounding environments reveals the physics of these enigmatic objects,” Paul Hertz, director of NASA’s astrophysics division, said in a statement at the time. The project, he said, “will open a new window on the universe for astronomers to peer through.”

A preliminary launch date is set for April 2021 on a Falcon 9 rocket from Launch Complex 39A in Florida. It’s unlikely it will take up the full payload of the rocket, as SpaceNews.com points out.
