Why it is dangerous to build ever larger big bang machines

CERN has revealed plans for a gigantic successor of the giant atom smasher LHC, the biggest machine ever built. Particle physicists will never stop to ask for ever larger big bang machines. But where are the limits for the ordinary society concerning costs and existential risks?

CERN boffins are already conducting a mega experiment at the LHC, a 27km circular particle collider, at the cost of several billion Euros to study conditions of matter as it existed fractions of a second after the big bang and to find the smallest particle possible – but the question is how could they ever know? Now, they pretend to be a little bit upset because they could not find any particles beyond the standard model, which means something they would not expect. To achieve that, particle physicists would like to build an even larger “Future Circular Collider” (FCC) near Geneva, where CERN enjoys extraterritorial status, with a ring of 100km – for about 24 billion Euros.

Experts point out that this research could be as limitless as the universe itself. The UK’s former Chief Scientific Advisor, Prof Sir David King told BBC: “We have to draw a line somewhere otherwise we end up with a collider that is so large that it goes around the equator. And if it doesn’t end there perhaps there will be a request for one that goes to the Moon and back.”

“There is always going to be more deep physics to be conducted with larger and larger colliders. My question is to what extent will the knowledge that we already have be extended to benefit humanity?”

Doctoral Student Just Published a Paper Describing How Time Travel Would Be Possible

Posted by in categories: cosmology, physics, time travel

And how to build a time machine.

The concept of time travel has always captured the imagination of physicists and laypersons alike. But is it really possible? Of course it is. We’re doing it right now, aren’t we? We are all traveling into the future one second at a time.

But that was not what you were thinking. Can we travel much further into the future? Absolutely.

5 Sci-Fi Books Biotech Geeks Should Read Right Now

Posted by in categories: biotech/medical, robotics/AI, space travel, time travel

From space colonization to resurrection of dinosaurs to machine intelligence, the most awe-inspiring visions of humanity’s future are typically born from science fiction.

But among an abundance of time travel, superheroes, space adventures, and so forth, biotech remains underrepresented in the genre.

This selection highlights some outstanding works (new and not so new) to fill the sci-fi gap for biotech aficionados.

Scientists invented a real-life flux capacitor, but not for time travel

Posted by in categories: education, time travel

If you watched Back to the Future over the holiday weekend and wished the flux capacitor was a real thing so you could travel through time, we have sorta good news. Scientists from Australia and Switzerland have proposed a real-life flux capacitor — but you won’t be able to travel back to a high school dance in the ’50s with it.

The device is a new type of electronic circulator, which can control the directional movement of microwave signals. The scientists, who published their research in Physical Review Letters, have proposed two different potential circuits — one of them borrows the design of the three-pointed flux capacitor Doc Brown and Marty McFly used to travel to 1955 and 2015 in their DeLorean.

[1805.03035] Time travel in vacuum spacetimes

Posted by in categories: information science, time travel

The possibility of time travel through the geodesics of vacuum solutions in first order gravity is explored. We present explicit examples of such geometries, which contain degenerate as well as nondegenerate tetrad fields that are sewn together continuously over different regions of the spacetime.

These classical solutions to the field equations satisfy the energy conditions.
