comment How long would it take to get to Kepler 189f?
Perhaps because it's not a very interesting question. You're basically just asking us to do some calculations for you. Why wouldn't you just do them yourself? There's nothing particularly enlightening about these calculations that would make them interesting to anyone else.

Hi PleaseHelpMeOut, and welcome to Physics Stack Exchange! This is not a homework help site, so the sorts of questions you're asking are off topic. If you would like to post questions here, please take a look at our homework policy and make sure you're asking conceptual questions after having shown some effort to work through the problem.

comment Normalizing the sum of wavefunctions and calculating probabilty - understanding concepts
(1) It's not true that $\phi_1(x)\phi_1^*(x) = 1$. The product $\phi_1(x)\phi_1^*(x)$ is a function, which will in general vary with $x$. Only when you integrate it do you get 1. (2) I had made a mistake by omitting the absolute value signs; $a^*a = \lvert a^2\rvert$, not $a^2$, but accounting for that, yes that is the reason you get $\lvert a\rvert^2 + \lvert b\rvert^2 = 1$. (3) Exercise for the reader :-) Try the procedure I showed you on that function and see if it's normalized.

comment Why don't we substitute for $p$ in $E = pc$?
It might also be worth mentioning that $\gamma\to\infty$ as $v\to c$.

I've edited your question to improve the wording. Could you verify that it still accurately reflects what you wanted to ask?

comment Solving oscillation-related problems using energy
Hi lbicsi, and welcome to Physics Stack Exchange! This is a site for focused questions about specific concepts; just asking for links to documentation/tips/explanations in general is not on topic here. (Also, the sample problems don't seem to contribute anything useful to your question in its current form.) If you can edit your question to ask something specific, I'll be happy to reopen it.

comment How Are Galaxies Receding Faster Than Light Visible To Observers?
By the way, it's generally better to edit your existing answer, rather than deleting and posting a new one (unless the new answer is really completely independent of the original one).
