Physicists just confirmed a pear-shaped nucleus, and it could ruin time travel forever (Could be a paradigm shifting discovery)

[Master Disaster]

Brace yourself, this is a long one. 

 

Physicists have just discovered a second pear shaped nucleus in an element, something which until 2013 was thought to be an impossibility, this discovery of a second instance proves the first discovery was correct and that atomic nuclei can come in more than the previously thought 3 shapes. 

Quote

Physicists have confirmed the existence of a new form of atomic nuclei, and the fact that it’s not symmetrical challenges the fundamental theories of physics that explain our Universe.

 

But that's not as bad as it sounds, because the discovery could help scientists solve one of the biggest mysteries in theoretical physics -where is all the dark matter? - and could also explain why travelling backwards in time might actually be impossible.

 

"We've found these nuclei literally point towards a direction in space. This relates to a direction in time, proving there's a well-defined direction in time and we will always travel from past to present," Marcus Scheck from the University of the West of Scotland told Kenneth MacDonald at BBC News.

 

So let’s back up here, because to understand this new form of atomic nuclei, you have to get to know the old ones first. Until recently, it was established that the nuclei of atoms could be one of just three shapes - spherical, discus, or rugby ball. 

 

These shapes are formed by the distribution of electrical charge within a nucleus, and are dictated by the specific combinations of protons and neutrons in a certain type of atom, whether it’s a hydrogen atom, a zinc atom, or a complex isotope created in a lab.

The nuclei shapes were thought to be bound by a theory which entails C symmetry and P symmetry. 

Quote

The common factor across all three shapes is their symmetry, and this marries nicely with a theory in particle physics known as CP-Symmetry. CP-symmetry is the combination of two symmetries that are thought to exist in the Universe: C-Symmtery and P-Symmetry. 

 

C-Symmetry, also known as charge symmetry,  states that if you flip an atomic charge to its opposite, the physics of that atom should still be the same. So if we take a hydrogen atom and an anti-hydrogen atom and mess with them, both should respond in identical ways, even though they have opposite charges.

 

P-Symmetry, also known as Parity, states that the the spatial coordinates describing a system can be inverted through the point at the origin, so that x, y, and z are replaced with −x, −y, and −z. 

 

"Your left hand and your right hand exhibit P-Symmetry from one another: if you point your thumb up and curl your fingers, your left and right hands mirror one another," Ethan Siegel from It Starts With a Bang explains.

 

CP-Symmetry is a combination of both of these assumptions. "In particle physics, if you have a particle spinning clockwise and decaying upwards, its antiparticle should spin counterclockwise and decay upwards 100 percent of the time if CP is conserved," says Siegel. "If not, CP is violated.”

 

The possibility that the Universe could actually violate both C-Symmetry and CP-Symmetry is one of the conditions that have been proposed to explain the mystery of antimatter in the Universe. But proving that would mean the Standard Model of Physics needs a serious rethink.

 

According to the laws of physics, at the time of the Big Bang, equal amounts of matter and antimatter had to have been created, but now, billions of years later, we’re surrounded by heaps of matter (solid, liquid, gas, and plasma), but there appears to be almost no naturally occurring antimatter.

 

"This is a puzzling feature, as the theory of relativistic quantum mechanics suggests we should have equal amounts of the two," mathematician Gianluca Sarri from Queen's University Belfast in the UKwrites for The Conversation. "In fact, no current model of physics can explain the discrepancy."

This discovery is likely going to have a pretty big impact in the physics world with some theories having to be rewritten and others dropped entirely, including the Standard Model and current theories on anti matter (or the lack thereof). 

Quote

Okay, so back to our atomic nuclei shapes. Most of our fundamental theories of physics are based on symmetry, so when physicists at CERN discovered an asymmetrical pear-shaped nucleus in the isotope Radium-224 back in 2013, it was a bit of a shock, because it showed that nuclei could have more mass at one end than the other. 

 

Now, three years later, the find has been confirmed by a second study, which has shown that the nucleus of the isotope Barium-144 is also asymmetrical and pear-shaped.

 

"[T]he protons enrich in the bump of the pear and create a specific charge distribution in the nucleus," Scheck told the BBC. "This violates the theory of mirror symmetry and relates to the violation shown in the distribution of matter and antimatter in our Universe."

 

While physicists have suspected that Barium-144 has a pear-shaped nucleus for some time now, Scheck and his team finally figured out how to directly observe that, and it turns out its distortion is even more pronounced than predicted.

So about now your probably thinking, "What does this have to do with Time Travel exactly?" 

Quote

So what does all of this have to do with time travel? It's a pretty out-there hypothesis, but Scheck says that this uneven distribition of mass and charge causes Barium-144's nucleus to 'point' in a certain direction in spacetime, and this bias could explain why time seems to only want to go from past to present, and not backwards, even if the laws of physics don't care which way it goes. 

 

Of course, there's no way of proving that without further evidence, but the discovery is yet another indication that the Universe might not be as symmetrical as the Standard Model of Physics needs it to be, and proving that could usher us into a whole new era of theoretical physics. 

 

The study has been published in Phyiscal Review Letters, and can be accessed for free at arXiv.org.

Quote honestly, this seems like one of those paradigm shifting discoveries that will radically change our understanding of physics. 

 

I won't pretend to fully understand everything I just posted but from what I do understand, matter seems to inherently want to only travel forward in time. 

 

Thoughts?

Look at all these words i don't understand. Cool i guess ?

Boulderdash!

 

My flux capacitors still work just fine.

[HoiDaniel]

I don't think people fully understand how much of a milestone this is for anyone who is into physics!

 

Amazing that they discovered a confirmation for a weird assumption they made back in 2013. I'm curious to see if there are more elements which lead to these pear-shaped isotopes. Maybe they will discover that some elements won't produce any more forms, which could cause a lot of confusion

 

PS: CERN is awesome; been there last december and it's literally the coolest physics 'lab' i've ever seen!

It wasn't an assumption, I believe they measured Radium and discovered the pear shape, announced it and we're met with some resistance so they've repeated the experiment with Barium and discovered the same thing. 

 

Also calling CERN a lab is like calling a Lykan Hypersport a car, it's true but we all know that it's wrong.

OMG YOU NOOB WAIT FOR THE RX 480 TO COME OUT "LTT members before the RX 480"  

I personally never been into physics all i care is the world gonna be ok or are we all doomed from the Cookie Monster

Well we've know time travel will never exist since ever basically. If it would exist we would have it already. Or Earth died before we could discover it fully.

That's a hypothesis only for backwards time travel and does not rule out other possibilities for why we have not encountered time travelers. This one if true rules out all other possibilities.

[Starelementpoke]

Does this change the probably of dimension hopping?

One would assume anyone intelligent enough to backwards time travel successfully wouldn't get caught.  I seem to remember reading into a lot of articles dating modern items back way before their time.  I believe one was a watch found in a previously undiscovered, unopened sarcophagus and a metal hammer or axe with a wooded handle encased in stone.

 

EDIT:  The Hammer is 'The London Hammer' the other is a ring etched to look exactly like a swiss watch.

Thoughts? 

Time in almost every theory is just another coordinate. So instead of a 3 coordinate system that describes position (x, y, z) you have 4 which needs a different mathematical system to be described. This system however does not put any restrictions in regards of the values an object takes inside it, which means there is no reason any object in it has to only move forward on the 4rth coordinate( time). This contradicts our every day observations and can be translated in 2 ways : Either the mathematical description is inaccurate or we just haven't found how an object travels backwards on the time coordinate. This discovery seems to prove the first one right.

It does exist, everyone who ever goes into Space is a time traveller by a tiny margin. The thing is we can only ever go forward in time, not backwards.

At the rate of one second per second.

[Bsmith]

I was planning to make a comment that the shape of the nucleus might be a result of the difference in matter and anti matter in the early stages of the universe.
But after reading some of the comments I already noticed it would be to waste here.

True, yes. I'd much rather travel Forward in time aswell.

That's some BS. Why would someone travel time just to place something old into even older times? lol.

Total proof.

If we found something that is far beyond our Technology then i'd believe it (probably not, just if i found it myself lol).

I don't know, it's just strange and unexplained. I brought it up because there's actually quite a large amount of unexplained artifacts that date way back. The ones I listed were from recent memory, but far from the most exciting (Antikythera Mechanism IMO). Not saying it's definitive proof or anything, I just enjoy thinking about the unexplained.

 

Curious... Most curious.
