comment Plot of gauge coupling unification
Ah I see they are of the same order. Thanks for clarifying.

comment Plot of gauge coupling unification
What is meant by "consistent" here? Is it "making up for discontinuity"?

comment Horizon problem in the standard cosmological model
Thanks John for the answer. So, how does inflation solve this? And does it abandon the infinite universe assumption?

comment Running of gauge couplings in the Standard Model
I agree, and I don't think it will be helpful to anyone except me since I made a mistake and realized it has nothing to do with physics. ;-p

Or even better is the LogLinearPlot function which plots log scale on the x-axis only.

comment Running of gauge couplings in the Standard Model
Yes you are right, I took it twice like any stupid would do.. I suspected I did something wrong in my plotting. Now I get the desired plot when I use the LogLogPlot function. Previously I used Plot, with the interval being from Log[MZ] to Log[10^16] so the log was taken twice.

comment How to handle Yukawa contractions in calculating SUSY beta functions?
Thanks a lot Dr Motl, now I managed to go through all one-loop and some two-loop calculations :) All the best Sir.

comment Which SUSY models are affected by the recent LHCb result?
Thanks indeed for this. Dr. Motl's answer helps a lot. Especially the comment that models requiring large $\tan \beta$ and squarks below 1 TeV. But I hope to get a more elaborative answer here.

comment mSUGRA boundary conditions and the MSSM
@user788171 $m_{H_u}^2$ is negative at the weak scale, allowing electroweak symmetry breaking radiatively. I suggest that you read Martin's reference that I mentioned earlier.

comment mSUGRA boundary conditions and the MSSM
@Anirbit I believe I was reading Martin's Susy primer: arxiv.org/abs/hep-ph/9709356.

comment Hierarchy is no problem and susy is a mathematical tool for data fitting
I know I asked this long ago, but what I understood from you and Lubos and Matt, that there is a real hierarchy problem in the SM. But what about those who say, if there's nothing but the SM, then there's no problem at all since the theory is normalizable?

comment Why does the running of the gauge couplings show $\frac{1}{\alpha}$ > $\frac{1}{\alpha_w}$ at low energy?
The plots that you are seeing and asking about are plotting the inverse of $\alpha's$. So, nothing is messed up. The larger will become smaller, and the smaller will become larger when you take the inverse of things.

Thanks Dr Motl for the answers and the link to your blog post.

comment Non linear QM and wave function collapse
Can you explain to us what is the probabilistic ontology and what is the issue of global rescaling?

@jaskey13 I honestly have no idea. I hope I could understand the argument of this whole issue.

About the zero energy universe, there's a good discussion here: mathoverflow.net/questions/38659/total-energy-of-the-universe

@MattReece I hope you consider adding an answer for the benefit of all. Especially about the mass-vev confusion.

comment How can I explain why the weak nuclear interaction between individual nucleons is 'weak'?
-1: a number of people won the Nobel prize for their work on these two interactions!

comment How exactly does time slow down near a black hole?
Your last remark reminded me of the twin paradox. So the one who returns to Earth will be back in the future? To me the situation you described is similar in principle, right?
