I PASSED MY BEGINNING ALGEBRA CLASS WITH A B!

Wish I could see the image.

The Nana afterglow is over. You'll have to hope I get to go down on Christmas weekend so you get another reprieve when I get back.

All things back to normal I see.

OHHHHHHHHHHHHHHHHHHHHHHHHHHYESSSSSSSSSSSSSSSSSSHHHHHHHHH

Congratulations, what an awesome job! My daughter has an algebra exam this coming Tuesday that she isn't exactly thrilled about!

Silly people. They use algebra all the time. No, we don't sit at home and think of 2(a+b)=c equations. But the logic that goes into it, the linear method of calculation, the breaking of an issue into component parts - we do that all the time. We just don't call it x, y, z.

Thank you.

Yep yep! It took me so long to realize that higher math teaches you a methodical way of thinking that's useful in most of life. As someone whose mind is going a mile a minute and making huge jumps all the time, the thinking skills I learned from math are invaluable. I tell my kids that now, and they just roll their eyes. They'll learn.

Oh, and congrats, Connor!

Well done you! Just never could figure it out.

You get an A

next question related to what you said... Is there a black hole at the center of galaxies? Does it move?

Sorry, bouncetastic! Missed this.

Yes, there's a black hole in the center of the galaxy, a massive one. May likely be a black hole at the center of most galaxies, which makes sense - you have a lot of mass in galaxies that will gravitate (nyuk!) toward itself inwardly. Maybe the whole appearance of our galaxy is a huge accretion disc.

Yes, the black hole moves. Black holes have spin. And since the galaxy is moving its way through its galactic neighborhood specifically and the cosmos generally, the black hole at the center is moving along with it.

Thanks I didn't know if it was just theory or if it was pretty much accepted as fact. It's logical.

I'm sorry Connor B I did not mean to turn your thread into a math and science classroom lol. I've been out of school for too long Quarks hadn't even been discovered when I was in school.

Next question... Are wormholes science fiction or fact?

Fact!

Fact!

Well, they're certainly science fiction. But they might also be fact. They're hypothetical.

Imagine a black hole, a singularity, gobbling up matter and the gravity around it. If you use the stereotypical example of a weight on a trampoline surface, the weight is getting heavier and heavier, and the rubberized surface is dimpling deeper and deeper. Rover's chew toy, loose change, a tennis ball, even dust that is on that surface keep getting sucked down to that weight, making it heavier and dimpling yet more. It's really stretchy. It's stretched down a few hundred feet now.

And so in our weight/trampoline thought experiment, what happens is that the weight gets so heavy that a piece of that surface finally rips open near the bottom. The weight and its accretion is still weighing down the surface, so you've still got that big, deep dimple, but now some long-lost keys are sliding down, and rather than adding their mass to all that weight, they slide through the rip, out of that long dimple-tube, to the world outside.

Now, there's a lot more that actually would go on with a real wormhole, and I'm sure that astro/quantum/theoretical physicists would sneer at my description. But there you have it, best I can do.

That's theoretical. But lots of theoretical stuff, such as black holes and subatomic particles, have an interesting way of actually being proven.

I opened a can of worms when I mentioned mathematics, didn't I? Einstein and Nash are reading this thread in Heaven and having fun.

I like your trampoline example and I will not sneer Thanks for taking the time to explained it!

Yes you did lol. *hides Connor B's can-opener*

A repeat of The Big Bang Theory was on yesterday evening, the one in which Neil deGrasse Tyson was a guest star. Sheldon is angry at him for declaring Pluto is not a planet.

Why isn't Pluto considered a planet? And if Pluto isn't a planet, what is it???

It doesn't meet the third rule set up by the International Astronomical Union. Here are the three rules they've determined are the criteria for designation as a planet:

• A planet must be round.
• A planet must orbit the sun.
• A planet must have “cleared the neighborhood" of its orbit. This means that as a planet travels, its gravity sweeps and clears the space around it of other objects. Some of the objects may crash into the planet, others may become moons.

Oops, forgot the last part of your question. It's now considered to be a "dwarf planet" as it still meets the first two criteria.
