The quest to crystallize time
Bizarre forms of matter called time crystals were supposed to be physically impossible. Now they’re not.

Christopher Monroe spends his life poking at atoms with light. He arranges them into rings and chains and then massages them with lasers to explore their properties and make basic quantum computers. Last year, he decided to try something seemingly impossible: to create a time crystal.

The name sounds like a prop from Doctor Who, but it has roots in actual physics. Time crystals are hypothetical structures that pulse without requiring any energy — like a ticking clock that never needs winding. The pattern repeats in time in much the same way that the atoms of a crystal repeat in space. The idea was so challenging that when Nobel prizewinning physicist Frank Wilczek proposed the provocative concept1 in 2012, other researchers quickly proved there was no way to create time crystals.

But there was a loophole — and researchers in a separate branch of physics found a way to exploit the gap. Monroe, a physicist at the University of Maryland in College Park, and his team used chains of atoms they had constructed for other purposes to make a version of a time crystal2 (see ‘How to create a time crystal’). “I would say it sort of fell in our laps,” says Monroe.

And a group led by researchers at Harvard University in Cambridge, Massachusetts, independently fashioned time crystals out of 'dirty’ diamonds3. Both versions, which are published this week in Nature, are considered time crystals, but not how Wilczek originally imagined. “It’s less weird than the first idea, but it’s still fricking weird,” says Norman Yao, a physicist at the University of California, Berkeley, and an author on both papers.

Time is relative, and flexible and, according to Einstein, “the dividing line between past, present, and future is an illusion”. So reality is ultimately TIMELESS. This sounds pretty bizarre from the view of classical physics, but from the view of consciousness theory and spirituality, it fits in perfectly.

Black holes are a passage to another universe, says Stephen Hawking
Humans could escape from black holes, rather than getting stuck in them, according to a new theory proposed by Stephen Hawking.

Unfortunate space travellers won’t be able to return to their own universe, according to Hawking. But they will be able to escape somewhere else, he has proposed at a conference in Stockholm.

Black holes in fact aren’t as “black” as people thought and could be a way of getting through to an alternative universe.

“The existence of alternative histories with black holes suggests this might be possible,” Hawking said, according to a report from Stockholm University. “The hole would need to be large and if it was rotating it might have a passage to another universe. But you couldn’t come back to our universe. So although I’m keen on space flight, I’m not going to try that.

Hawking’s proposal is an attempt to answer a problem that has tormented physicists about what happens to things when they go beyond the event horizon, where even light can’t get back. The information about the object has to be preserved, scientists believe, even if the thing itself is swallowed up — and that paradox has puzzled scientists for decades.

Now Hawking has proposed that the information is stored on the boundary, at the event horizon. That means that it never makes its way into the black hole, and so never needs to make its way out again either.

That would also mean that humans might not disappear if they fall into one. They’d either stay as a “hologram” on the edge, or fall out somewhere else.

“If you feel you are in a black hole, don’t give up,” he told the audience at the end of his speech. “There’s a way out.”


Finally! Hawking finally said it! YES!

“His passing has left an intellectual vacuum in his wake. But it’s not empty. Think of it as a kind of vacuum energy permeating the fabric of spacetime that defies measure.”

So I know durinswizardwheezes just made a powerpoint but she inspired me to make one too because YOU CAN NEVER HAVE ENOUGH AND OMG THIS SHOW I SWEAR

This is inspired by durinswizardwheezes’ powerpoint and ninthfeather’s post quantum-angel’s powerpoint and and envy-loves-you’s post (spoilers in the last two)

“If there is energy within the substance it can only come from without. This truth was so manifest to me that I expressed it in the following axiom: ‘There is no energy in matter except that absorbed from the medium…’ If all energy is supplied to matter from without then this all important function must be performed by the medium.”

“When radio-active rays were discovered their investigators believed them to be due to liberation of atomic energy in the form of waves. This being impossible in the light of the preceding I concluded that they were produced by some external disturbance and composed of electrified particles. My theory was not seriously taken although it appeared simple and plausible. Suppose that bullets are fired against a wall. Where a missile strikes the material is crushed and spatters in all directions radial from the place of impact. In this example it is perfectly clear that the energy of the flying pieces can only be derived from that of the bullets. But in manifestation of radio-activity no such proof could be advanced and it was, therefore, of the first importance to demonstrate experimentally the existence of this miraculous disturbance in the medium. I was rewarded in these efforts with quick success largely because of the efficient method I adopted which consisted in deriving from a great mass of air, ionized by the disturbance, a current, storing its energy in a condenser and discharging the same through an indicating device. This plan did away with the limitations and incertitude of the electroscope first employed and was described by me in articles and patents from 1900 to 1905. It was logical to expect, judging from the behavior of known radiations, that the chief source of the new rays would be the sun, but this supposition was contradicted by observations and theoretical considerations which disclosed some surprising facts in this connection.

“Light and heat rays are absorbed in their passage through a medium in a certain proportion to its density. The ether, although the most tenuous of all substances, is no exception to this rule.  Its density has been first estimated by Lord Kelvin and conformably to his finding a column of one square centimeter cross section and of a length such that light, traveling at a rate of three hundred thousands kilometers per second, would require one year to traverse it, should weigh 4.8 grams. This is just about the weight of a prism of ordinary glass of the same cross section and two centimeters length which, therefore, may be assumed as the equivalent of the ether column in absorption. A column of the ether one thousand times longer would thus absorb as much light as twenty meters of glass.  However, there are suns at distances of many thousands of light years and it is evident that virtually no light from them can reach the earth. But if these suns emit rays immensely more penetrative than those of light they will be slightly dimmed and so the aggregate amount of radiations pouring upon the earth from all sides will be overwhelmingly greater than that supplied to it by our luminary. If light and heat rays would be as penetrative as the cosmic, so fierce would be the perpetual glare and so scorching the heat that life on this and other planets could not exist.

“Rays in every respect similar to the cosmic are produced by my vacuum tubes when operated at pressures of ten millions of volts or more, but even if it were not confirmed by experiment, the theory I advanced in 1897 would afford the simplest and most probable explanation of the phenomena. Is not the universe with its infinite and impenetrable boundary a perfect vacuum tube of dimensions and power inconceivable? Are not its fiery suns electrodes at temperatures far beyond any we can apply in the puny and crude contrivances of our making? Is it not a fact that the suns and stars are under immense electrical pressures transcending any that man can ever produce and is this not equally true of the vacuum in celestial space? Finally, can there be any doubt that cosmic dust and meteoric matter present an infinitude of targets acting as reflectors and transformers of energy? If under ideal working conditions, and with apparatus on a scale beyond the grasp of the human mind, rays of surpassing intensity and penetrative power would not be generated, then, indeed, nature has made an unique exception to its laws.

"It has been suggested that the cosmic rays are electrons or that they are the result of creation of new matter in the interstellar deserts. These views are too fantastic to be even for a moment seriously considered. They are natural outcroppings of this age of deep but unrational thinking, of impossible theories, the latest of which might, perhaps, deal with the curvature of time. What this world of ours would be if time were curved…“

“The Eternal Source of Energy of the Universe, Origin and Intensity of Cosmic Rays.” October 13, 1932.

In Steven Moffat’s Listen, we learn from a jaunt into Gallifrey’s, and the Doctor’s, past that, had the young First Doctor not passed his Time Lord initiation, he would have been sent to Gallifrey’s army (and I suppose this would be the case of all Gallifreyan children?). I think an implication of the episode is that he would have failed the initiation and become a soldier had he not been visited and given courage by Clara… 

In the late Craig Hinton’s The Quantum Archangel, the Quantum Archangel creates a timeline where the Doctor is an Admiral of the Time Lord army and timeship fleet in a time War parallel and nearly identical to the War in Heaven seen in Alien Bodies and The Taking of Planet 5, with the key difference being the identity of the enemy strongly implied to actually be the Daleks. While the implication of the novel’s passage is that this version of the Doctor is the Sixth, the star of the novel, it never actually asserts it… 

Rachael Stott, comic artist and frequent contributor to Titan Comics’ Twelfth Doctor canon, has been producing images on her own time that demonstrate a very interesting AU for the Whoniverse… 

And… 

… how seriously do I want to canon weld the timeline seen in The Quantum Archangel into a version of reality where the Doctor did fail his Time Lord initiation, was sent to the military academy with the Master, lived their lives in the service of greater Gallifrey, before a dark and terrible War in Heaven, preceded by the machinations of Faction Paradox and the splintering of the Celestis, the screaming and raging enemy of Skaro aiming its angry eye at the Shining World of the Seven Systems, calling the Twelfth Doctor (not the Sixth) to duty? 

Pretty goddamn seriously. 

The soul of humanity

“So, that should about cover it Captain.”
“That’s good Roger. I trust that you have a handle on things. It all looks good.” He tapped a few places on his data pad Before setting it down to lift a still steaming cup to his lips.
“I know I’ve been here two months, and I’ve tried not to ask, but…” He paused, looking up at the wall over the Captain’s shoulder. “Is it real?”
The captain raised his eyebrows as he swallowed, recognizing that gleam in his new first officers eyes. “Real?” He put down his cup. “Yes it’s real. That is absolutely sure. Is it the original? There’s no way to know something like that. It could have been changed out a dozen times before such things mattered.” Nathan stood and moved to the small relic hanging on an ornate plaque. “It is the oldest confirmed however. Would you like to hold it?”
“Can I?” He sat forward excitedly.
“Sure.” Nathan lifted it reverently from its place, and carefully handed it to Roger. “The problem becomes the same as the ship of theseus. How many parts can be replaced before something just isn’t the same thing anymore?”
The knife was somehow heavier than he expected. The handle had been roughly drilled out to accommodate the bolts for the brackets which had once held it in place. While obviously well cared for, and fogged with a resistant nano-coating, the blade was pitted with age. It was a standard issue kitchen knife for the time it had been issued, not special on its own in any way. He examined the point, and could see where it had been repaired and resharpened uncountable times. The point had either been rounded off or broken at some point, and ground back into piercing sharpness.
The Captain continued, “They kept ‘em running for dozens of years past any of the others of his model. Scavenged parts at first, when manufacturing stopped. Custom machined bits when those ran out. They say that some of the last silicon based micro processors in existence are on one of his motherboards in the smithsonian back on earth.” He held his hand out, and Roger carefully returned the blade. “He was a wonder. A hero.” He set the knife back on its perch. “In many ways he embodied our collective human soul.” Nathan turned back to Roger, “I saw him once myself, as a child, at a parade before the incident with the K’arneen. Saved the whole Goddamn human race by throwing himself into that reactor.”
“I’m proud to be serving here on his namesake Sir.”
“Good. I am proud to be her captain.” The emergency klaxon chimed as a red light blinked above the Captain’s ready room door. “Looks like it’s go time. Let’s show them what it means to piss off humanity.” They both passed through the door to the bridge, filled with a flurry of controlled madness. “Status helm?” Nathan said, looking up at the Imperial dreadnaut filling the forward screen. A dozen miles in length, and half as many thick. He could see energy pulses issuing from it, and being directed towards it. Explosions randomly blossomed and died across it, seemingly doing little damage.
“Battle was already in progress when we arrived. I believe we have been able to detect the main reactor core, targeting now.” The helmsman said, not looking up from her controls.
“Good. Engineering? Are we ready?”
“We are ready. Activating integrity field, and quantum string edge now.” The voice from the communication panel chimed. Energy danced out across the hardened, disk shaped, hull. An elongated prow jutted from the bow, a knife edge forged from pure neutronium, pulled from the heart of a dead star, honed until the edge was lost in the plank scale quantum foam of time-space.
“Target locked Captain.”
The Captain pressed his com for a ship wide announcement. “All hands brace for attack. Helm. Ramming Speed.”
“Aye sir.”
The E.S.S Stabby McStabface was suddenly thrust toward the dreadnaught by powerful sublight ramjump engines. The enemy was crew shocked, fully unprepared for such an insane maneuver. Their energy shields were useless, heavy armor no match for the sharpened density of high velocity neutronium. Stabby plunged full bodied into the enemy ship, cleaving through its heart before emerging unscathed on the far side. As she turned to begin another pass; a blast wave of radiation, gas, and debris rocked Stabby as the Dreadnaught came apart.
“Captain enemy vessels are beginning to move away from the area.”
“Follow them, and take them out. Target larger vessels first. Show ‘em what Stabby’s got.”
“Aye sir.” The Helmsman said, plotting the next attack vector before engaging the ramming drive.

anonymous asked:

Is there something like the shortest possible time in physics?

Yes! The shortest length of time is known as the Planck time, and is about 5.3*10^-44 seconds long. Of course, this might not make much sense, as you could always keep cutting this in half to make shorter and shorter times, but that doesn’t really work in quantum mechanics.

In quantum mechanics, certain properties of a system will always have some uncertainty associated with them. For instance, if you were to measure the amount of time it took for a particle to decay, the most precise you could ever possibly measure it would be to the nearest Planck time. There is no possible way you could get any more precise than this in principle, which makes this the smallest possible unit of time.

The same can be said for units of length, as well. The smallest unit of distance possible is the Planck length, which is about 1.6*10^-35 meters long. Just like with the Planck time, it is impossible to measure the position of an object below the precision of one Planck length.

Note, it’s not that we don’t have the technology to measure below these levels, it’s that time and space actually behave differently below these units. It makes no sense to talk about half a Planck length or Planck time, since our concepts of space and time don’t really exist on these levels.
