David McClintock Presents: We Need a New Kind of Physics.
Near us at the ordinary "standard" forces we are familiar with and experience, Newtonian mechanics work alright.
At galactic distances, Einsteinian mechanics work.
At very small sub-atomic distances, quantum mechanics work.
We still haven’t managed to put all those different mechanics together, but something new has arrived:
Under enormous forces, things appear to work in ways we have no understanding of.
We can see, observe, and show that stuff can do things we cannot even imagine good theories for - yet.
1. We cannot (yet) spin any magnet at any speed and get out a stream of anti-matter.
But neutron stars do that.
From observations at many neutron stars, we are quite sure that spinning magnetic forces of huge intensity do emit matter and anti-matter.
We sure don’t know how.
We need new thinking about the physics involved with such enormous forces.
2. Since the Big Bang, we have evolved various ideas about the expansion of our universe.
We have reasoned it might be slowing down. We have measured its changing rate of expansion.
We now have data more precisely accurate than ever before.
To a three sigma level of confidence we have to take seriously that our universe is not expanding more slowly but is instead expanding ever faster.
Why? What force(s) cause things to accelerate faster and faster away from each other?
We profoundly do not know.
We need a new thinking about the physics involved there.

Stephen Goodfellow Presents: The Coronal Heating Problem
The Sun's core is supposed to be 10 Million Degrees Kelvin.
The Outer Atmosphere (Corona) is 2 Million degrees Kelvin.
...But the Sun's visible shell (Photosphere) is only 6000 Degrees Kelvin....how can that be?
...And what are the implications?

Phyllis Pitluga, our resident planetarium expert gives us a heads up:
I though that some of the science group might be interested in the Jan31st lunar eclipse. So here are the facts:
This Full Moon will again be closer to Earth than average so it is called a "Super Full Moon"
Also it is the second Full Moon in January (the other was on January 1st) so this makes it a "Blue Moon" but the color won't be blue. This refers to the rarity of two Full Moons in a month as "once in a blue moon." Since a month of phases is 29.5 days, usually there is only one Full Moon a month. So January 31st we will see a Super Blue Moon being eclipsed in Earth's shadow! Further, it will be at dawn when the skies at our longitude and on the opposite side of Earth affect the color of Earth's shadow. Cloudy skies equal a darker shadow and clearer skies refract the color of sunrise giving us a redder eclipsed Moon.
Looking northwest in San Miguel, the Moon enters Earth's shadow as follows:
31st lunar eclipse
5:48 a.m. Partial eclipse begins (on the left side of the Moon)
6:51 a.m. Total eclipse begins
7:21 a.m. Moon sets while partway through Earth's shadow (time depends on your horizon)
and the Sun is rising opposite the setting Moon-in-eclipse
Hope this inspires some to get up early!
