Question

-do protons decay?
-Why is there far more matter than antimatter in the universe?
-Why did the universe have such low entropy in the past, resulting in the distinction between past and future and the second law of thermodynamics? Why does time flow in one direction at all, on macroscopic scales, when there does not seem to be an arrow of time on the scale of fundamental interactions?

Answer 1

hi Fellow Genius !,
good question.

YES. Protons do decay. they have an average lifetime of about 10 to the power 32 years. Now, since this is an average, it should be possible to monitor a large enough collection of protons, and observe a few decays in the space of an year or so. Such experiments, involving 100s of tons of H2O or some other material, are underway in many parts of the world [eg.: a cave 600m below Lake Erie, Ohio]. However, none of them have yet [so far as I know] found any convincing evidence for the "predicted" decays of protons.

do take the trouble of replying if my answer satisfies ur curiosity or not. i am v. much interested in these questions. look out for my answer 2 the third part of ur question re the "arrow of time"

Answer 2

Some theories say that the decay of the proton does occur. None have been detected, so the answer is still a definite MAYBE.

I should say the following: The universe came to be in a certain set of initial parameters of density, temperature, energy, etc. and certain rules.What we are experiencing as time moving forward is the universes way of relaxing into a state of equilibrium, and following these rules. Clusters of matter are just some sort of statistical fluctuations on the way.

As to the 2nd law of thermodynamics, it is also statistical in nature. It states that anything wants to exist in a state of greater entropy. And entropy is a measure of in how many ways we can get the same effect. The more ways, the greater the entropy. So, the universe and everything will eventually arrive in the place that most roads lead to (Rome, probably)

As to the matter-antimatter question, I do not know and noone does for certain.

Answer 3

I deny genius status, but this is what i know:
- Yes. But it is more percise to say that protons CAN decay. The calculated mean lifetime of a proton is 10 to the 23 seconds. The universe has not yet been in existence that long. So as long as the lifetime of the universe is concerned, there is slim chance that a single proton has already decayed, let alone a number of protons have. So it is a bit incorrect to say that "protons decay", it is a statement in the perfect present.
- There are a number of explanations to this problem. One is that this question is too assuming. Some say that there might be equal ammounts of matter and anti-matter. The universe is just to big for them to mix like mambo. For example, some say there might be anit-matter galaxies and civilizations outside the visible universe. The supersting theories also seek to address this question. The bias of superstring theorists is that in the begginning, there has been a perfect symmetry in nature. But this symmetry was only broken by the separation of the fundamental forces. Another expalation is that total randomness has accidentally brought about a bias to the side of matter, just like tossing a single die for a finite number of times may violate a Gaussian distribution.
- I personally would like to think that entropy is not an arrow of time, but it is the other way around. Of course, I have no strong theory to back me up. Its just me.
The question of why time travels in one direction only has been a fundamental question for decades. That is why there is a problem with the gravitational force. The three other fundamental forces seem to be time reversible, while gravitation often times is not. When you see a video of an apple going up to the tree instead of falling down, you know that the video must be in rewind. As far as most classical thinkers are concerned, the increase of entropy of the whole universe is a fundamental law of things. They tend to think that it just is, like the fact that the value of the charge of the electron just is. So, in effect, the big bang is just a result of this fundamental law, that anything orderly is unstable and will always tend to be disordered, which seems to be more stable.

Answer 4

Protons are not living beings. They do not decay
Matter and Antimatter are equal in quantity. Matter can be seen while antimatter is not within the visible spectrum of human eye.
Entropy of the Universe is constant at all times.
Time is UniDirectional. Its motion is always relative to Space and Causation.
Time is not a fundamental interaction. It is a transcendental unit unrecognised in general physics

Answer 5

pal, Yahoo solutions is a pretty stay communicate board, i believe, the place human beings ,actual human beings work together and proportion what they understand with others ,or ask a question to get a competent respond to discover a answer to their situation despite it may be. there are particular greater souls answering right here in R&S area, and particular somewhat enormously knowledgeable human beings answering in different sections.So while you're trustworthy honestly you will benefit in this communicate board and improve mentally. The factors that come , and the ranges from one million to 7 are of no value to me.they are with the aid of -products.You be going and that they'd be acruing(factors) or depleting.do not hassle.this is not the standards that count, this is the Scholarly answer to our question that count. i myself experience that way please.

Answer 6

yes they do undergo decay
it takes 10^32 years





matter is more than anti-matter in this world
it's bcoz
if u r da matter , something against u is antimatter
i think now u have understood the fact



the dimension of time is not clear[for info on this, visit the Q on space-time in voting section]

Answer 7

no protons do not decay

Answer 8

We are not amused.In fact i'm baffled.

Answer 9

Sorry but What?

Answer 10

ummm......yeah....i guess...wait...what are we talking about??? : )
