This Is The One Symmetry That The Universe Must Never Violate

Physicists use the term “CP” (for “charge parity”) to talk about matter-antimatter symmetry. If nature treated matter and antimatter alike, then ...

Towards the ultimate question - Inters.org

Travel back in time through those phase transitions, and we see an ever-greater simplicity and symmetry, with the fusion of the fundamental forces of nature and ...

Does the Universe Violate the Laws of Thermodynamics?

We have come to the limit of our cherished conservation principles: when time and space themselves are mutable, time symmetry is lost, and ...

structure of the Universe. Charge symmetry is one such symmetry principle, under this symmetry, if one were to convert the up quarks in a proton into down ...

C, P, T (And Their Combinations) – Of Particular Significance

So it was quite surprising to physicists when, in the 1950s and 1960s, it was learned that the weak nuclear force violates all of these symmetries. The only one ...

The Nobel Prize in Physics 2008 - Popular information

Nature's laws of symmetry are at the heart of this subject: or rather, broken symmetries, both those that seem to have existed in our universe from the very ...

Time-Reversal Violation Is Not the "Arrow of Time" – Sean Carroll

So T has to be violated, to cancel out the fact that CP is violated and make the combination CPT a good symmetry. Either that, or the universe ...

The Universe Began In A State Of Extraodinarily Low Entropy

The standard picture holds that the initial conditions for the universe must have produced a special, low entropy state, because it is needed to explain the ...

Cosmology of the Symmetrical Relativity versus Spontaneous ...

From the present perspective, nothing is a primordial vacuum, whose information has made the universe by condensing and igniting. It was not randomly created, ...

The Mystery of CP Violation - MIT Physics

One reason for this assumption was the CPT theorem, which states that all quantum field theories must be symmetric under a combined transformation of C, P and T ...

The search for leptonic CP violation - CERN Courier

However, cosmology tells us that just after the cosmic Big Bang, the universe contained equal amounts of matter and antimatter. Obviously, for ...

Charm-quark decays violate charge–parity symmetry | Physics Today

The Big Bang should have yielded equal amounts of matter and antimatter, which should promptly have annihilated each other, leaving nothing but ...

Charge-parity violation - Symmetry Magazine

One of the great puzzles for scientists is why there is more matter than antimatter in the universe—the reason we exist. It turns out that the ...

LHCb tightens precision on key measurements of matter–antimatter ...

In 1964, James Cronin and Val Fitch discovered CP symmetry violation ... one of the Universe's best-kept secrets. Find out more on LHCb's ...

Natural laws can't be broken but can they be defined? | Aeon Essays

For instance, to borrow an example from the philosopher Hans Reichenbach (1891-1953), perhaps in the entire history of the Universe there never ...

Entropy: The Hidden Force Making Life Complicated - Farnam Street

I suppose it's part of the joy and tragedy of our lives, but out there in the universe, those grand and epic cycles appear eternal and unchanging. But that's an ...

6 Symmetry Tests in Nuclear Physics - The National Academies Press

Reversal of time is the only discrete transformation of space-time that has not been demonstrated to be broken. A violation of time-reversal symmetry means that ...
