Lucky those who get to see this. My system says I need new Adobe Flash Player, which is not true. Thanks for nothing.

Check out [url=https://asterisk.apod.com/viewtopic.php?p=286373#p286373]bystander's post[/url]. There is a youtube video there that is the same as the APOD. You can watch it there.

I notice Vega (located at 10^9.6 in the scale) is wobbly in the animation. Being wobbly doesn’t point to varying brightness, or bulging at the equator, or a debris cloud, which are known/implied [url=https://en.wikipedia.org/wiki/Vega]characteristics[/url] of Vega.

Hey, I noticed that Vega looked bluer in the animation than B-type Regulus and O-type Alnitak! Well, I'm [i]sort of[/i] okay with that, because due to the fact that it is quite flattened and that we see it pole on, where it is hottest and bluest, Vega really is the most obviously blue-looking of the bright stars in the sky. Certainly through a telescope!

Ahh, I stand corrected... :oops:

Thank you Charles and Ray Eames.

Great job. Remember seeing 'power of ten' as a child. This presentation will be of use to me, as it gives me understanding of the values of displacement from the smallest to the largest measurements we, as humans, can comprehend. Now if I can just wrap my mind around the extremes; tough to imagine. This is a fantastic show of dedication and application of intelligence. thx, C.

Flash? I can’t believe you are using this even though it’s been blocked by many browsers and all Apple products. Nothing is worth the security risk that program brings with it. Shame on you apod.

Thanks, bystander. I wouldn't have been able to see the APOD if you hadn't posted the youtube video.

Well, it's a Sunday repeat, dating back to when flash was acceptable. But yeah, if the authors of this nice interactive tool want to keep an audience, they need to update the content to HTML5. An awful lot of people are locked out of this, or have to jump through too many hoops to make it worth their while.

Fantastic job. Unfortunately the chosen Flash format makes it unavailable for those using Firefox or Chrome. I had to install Opera to see it.

Windows 10, Google Chrome just blocked flash. All you had to do is to allow it by pressing allow.
By the way it must be awful being a Zeptometer. And I don't mean to belittle it.

I came here to complain about the Huangs having the audacity to estimate the size of the universe, and I find mostly complaints about Flash! Not that I find that odd in retrospect.

Flash works fine on my Firefox (Firefox Quantum Extended Support Release 60.2.2est (64-bit) Firefox for openSUSE Leap 15.0). I haven’t gotten rid of it because there is one site I visit regularly that still uses it. And no, that site is [b]not[/b] skyandtelescope.com; I found an [url=http://www.etwright.org/astro/plani.html]HTML5 planisphere elsewhere[/url] on the Web.

But, yeah. Firefox has a special jaundiced eye on Flash, and tolerates it only because so many people keep doing stuff like submitting Flash apps to APOD. Firefox summarily blocks Flash every time Mozilla gets wind of a security hole, and nobody gets to run it again until they install the patch.

For years I’ve had Firefox configured to give that one aforementioned site a pass, and ask me to activate flash ad hoc for all other sites. I almost never do so; I did today, just because it’s APOD.

Flash? You've got to be kidding. Even Adobe is on its way to being rid of flash. I've long kept my computers flash-free because of the many security vulnerabilities of Flash.

Interesting! I'm still staggering on with a steam driven Vista platform but Chrome on mine works the Flash format just fine.

I'm not the first to suggest there's only one electron. Professor John Wheeler did but he immediately rejected the notion but he was right!!
[/quote]
This is a nice new size-zoom, and it is indeed impressive how utterly fantastical is the range of size measurements: from the electron (no measurable size) to the universe itself (possibly infinite in size). But DomeLord is right, it distracts from the more fundamental fact that there aren't actually ANY 'things,' there are just measurements.

I quite like this offering apart from the very minor quibble about the suggested size of the electron but there again by its very nature it precludes accurate measurement. They could have maybe shown the possible range though.

At some point it will be realized by all that there is only one electron visiting & animating all levels of reality everywhere apart, of course, from so-called black matter. I'm not the first to suggest there's only one electron. Professor John Wheeler did but he immediately rejected the notion but he was right!! How else, for example, does one solve the EPR Paradox? It is simply not possible in this space/time continuum to be simultaneously the observer & the observed.

Btw, should anyone want to know more about the contents of the Planck Epoch, do please get back to me. Have a nice day.

You're welcome. :ssmile:

The first time that I‘m disappointed about APOD, what a strange idea to present something in flash format. Well at least they triggered me to write my first comment.

No Flash allowed. It's 2018.
