TIL that our galaxy was made from a giant star that in its short life (due to its size) Supernova'd. Thus creating a large amount natural elements and gases. Due to the release of these extremely hot items, new stars and planets were created.
The one thing that Physicist write about is Dark Matter (it is dark because we cannot see it). Authors have written about Rouge Planets, Asteroids and comets. It comes to mind that all of those items can be made without a star to make them visible and could be just lurking out in the middle of space. No heat, no orbit just Dark Matter
In reply to MyMiatas :
Whenever I'm feeling down, I remind myself that we are all made of stars.
In reply to MyMiatas :
So, if dark matter only interacts with regular matter through gravity, shouldn't there be a lot of it that migrated to the center of the earth?
I thought "dark matter" was just non-radiative matter that we can't see with telescopes. We can see stars, we can see some planets, but we have planets we could only detect (at first) by calculating their gravitational perturbation.
How much mass does a completely dead star that didn't go nova account for?

"New, more accurate measurements of a group of colliding galaxies appear to indicate that the mysterious substance likely interacts with itself and ordinary matter only via gravity,"

From my readings it is a brown dwarf, with a maximum mass of 8 percent of our sun’s, or about 80 times the mass of Jupiter. They do not nova or become a different type of star. They end up just cold and drifting in there galaxy.
I think that you are talking about a Sun sized star becoming a White Dwarf which in the process of blowing off its outer shells at the end of its life, becomes a Red Giant which will engulf the Earth and what is left then shrinks down to the size of the Earth.
Density of "1 tonne per cubic centimetre". Or about the size of a sugar cube.

TIL (something that probably everybody else already knows) that silver is the most electrically conductive element. I had always thought that it was gold.

Congratulations Argentina in your World Cup Victory.
Not that anybody asked, but…
The chemical symbol for Silver, the most electrically conductive element on the Periodic Table, is “Ag,” from the Latin “Argentum,” after which Argentina is named.

It's also the most reflective. It might have at least one other "most" but I havent had eenuff coffee yet to remember..

^TIL.
In reply to Woody (Forum Supportum) :
When I was in the AF I won a free day off when my Staff Sargent said gold was the most conductive. I walked in the next day with a book from the library showing silver was and got the rest of the day off.
Gold's advantage is its non-tarnishing / corroding nature. I've got a lot of silver plated electrical connectors - they're used frequently in radio and microwave installations, especially military. But once they're exposed to oxygen they tarnish and need polished before reconnection.
In reply to Woody (Forum Supportum) :
IIRC, the advantage of gold over silver is it isn't as reactive with air, so doesn't lose conductivity like silver can.
Today i learned that a 5/8" fireplace door gasket is a different size than a 5/8"pellet stove door gasket.
Because of berkeleying course 5/8" isn't 5/8".
TIL that my wife has absolutely no sense of humor.
I added a new Ring security camera to my entry and for fun, I put on a hoodie, grabbed a crow bar, and did a cartoonish tip-tow up the entry followed by an equally cartoonish discovery of the camera / flustered run away.
She got the alert and just texted "thank you".

In the Corps you'd have done at least 100 push-ups for mouthing off to a staff NCO...
In reply to secretariata (Forum Supporter) :
That's why the AF values thinking over doing whatever you're told. You do know that the AF enlisted in the smartest armed force. We're the ones that send the officers off to fight while all the rest go fight for the officers. Love my Marine brothers. Semper Fi.

The grunts I know probably would have said it was worth it.

Baaah, sometimes thinking's overrated...
In reply to Appleseed :
Absolutely. I was just pointing out that it would not be a similar reward...

My mother worked for DEA in the late 70s/80s and for the EPA in the 90s. Our driveway always had some oddball drug seizure cars. Drug dealers/traffickers, with a few exceptions, have terrible taste in cars.
TIL that I can get tires in 185 45 15. An oddball size, but it can work very nicely on both the Firefly turbo, and the Spark. It's nice to have options
