Comments on: New measurements of the universe’s expansion rate https://behindtheblack.com/behind-the-black/new-measurements-of-the-universes-expansion-rate/ Fri, 27 Jan 2017 21:49:52 +0000 hourly 1 https://wordpress.org/?v=6.9.4 By: Edward https://behindtheblack.com/behind-the-black/new-measurements-of-the-universes-expansion-rate/#comment-961468 Fri, 27 Jan 2017 21:49:52 +0000 http://behindtheblack.com/?p=43907#comment-961468 My comment, while intended to be humorous, was also intended to point out the uncertainty of science, the need to verify previous conclusions, and the confusion many people have between precision and accuracy. Usually I am not that succinct on even a single topic.

Wayne, Joe, and Edward: Though I admit to many concerns and doubts about the James Webb Space Telescope, it is precisely the instrument we need to study deep space cosmology such as the Hubble Constant. This is what it was designed to do, and when launched, this will be its primary task, assuming of course it works as planned.

I would also concur.
A new telescope in Hawaii, would be a good start.

Saw that…. it’s “creepy.”

This experiment intersects with our discussion of the “Kara” robot / android and what consciousness and what being human may become.

Excellent Public-Lectures

Two recent lectures– on gravitational-waves & the science & non-science of Star Wars, are pretty good.

Absolutely. I totally forgot about Arp until you reminded me of him, so… good deal.
>It’s necessary to keep all these people (and their theories,) on their toes! (dead or alive)

I don’t mean to imply Dr. Penrose, has all the right answers, either.
Personally I do find his Conformal Cyclical Cosmology stuff to be fascinating.
He doesn’t like the “inflation” aspect of Bang Theory

a multiple repeat from me–

( I could watch Penrose play with overhead-projectors, all day long.)

Cool! Have all Susskind’s class-lectures downloaded and try to watch & re-watch them intermittently–I pick up new stuff every time, and the Math is becoming more familiar.

(Not a string-theory guy myself, but do find Susskind to be a ‘good explainer.’ And he’s the Master of Chalkboard’s!))
-Have seen the Theoretical Minimum lectures, and that topic is pretty complex.

My favorite super-genius, is Dr. Roger Penrose. (Master of the Overhead Projector) He’s been on a book tour promoting his new book — no new revelations from him, but very enlightening stuff.
>”Fashion, Faith and Fantasy in the New Physics of the Universe.”
Multiple videos from him at YouTube, discussing it.

His whole Theoretical Minimum series is well worth viewing.

Most excellent!

Have to disagree with Arp, although he raises some good questions.
As was noted in his obituary write-up, “He took a whole Cosmology with him when he died.”

Personally, I have problems with Bang Theory & Lambda-CDM myself, (but I only play a Cosmologist on the interweb) but it does appear to explain a lot.
(I also think we are on the verge of a major paradigm-shift but don’t think it will morph to Arp type stuff.)

I’d pivot slightly and recommend an enlightening lecture from Dr. Susskind, (although I’m not a string-theory guy myself.)
