Okay, I'm a very amatuer astronomer but that's pretty close from what I've read

oh, and it's not to scale

Ideas for Kids Star Wars Party! (Kids Talk Post)

Fjnbk says...

Make a corn hole, but call it Trench Run or something better than that. The beanbags the kids toss are actually proton torpedoes, and the holes to toss them into are thermal exhaust ports.

This idea isn't very good, but... C3PO Race. The kids have to walk like C3PO as fast as they can. Yeah, not very good.

That's what I can think of now, I'll post some more if they come to me.

How to: Demolish a house using AntiMatter!

demon_ix says...

The book (and now movie) Angels & Demons is built around the premise that someone (CERN and a random particle accelerator) managed to:

A. Create enough anti-matter to make a visible amount, or, a big blob of anti-matter. Kinda hard when collisions produce single atoms. Especially if you know what Avogadro's Number means.
http://en.wikipedia.org/wiki/Avogadro's_number

B. Separate that anti-matter from the rest of the atomic mess that would result from the actual generation of the anti-matter.

C. Contain that anti-matter without allowing it to touch any other matter, including pesky matter such as air, tables, containers of any kind, etc. In the book they solve this by creating magical vacuum containers with perfect magnetic fields that suspend the anti-matter in the exact center without allowing it to move in any direction. Since anti-protons would be negatively charged, I suppose that's a technical problem, not a theoretical one.

Anyway, I think Billy has his work cut out for him.

Well, some of the dust has settled (Blog Entry by MarineGunrock)

Spore Research: Outtakes

Free Radio Saturn

ELee says...

The audio is a representation of radio frequency signals measured at Saturn. The RF signals are described as 'kilometric' - which means wavelengths around a kilometer. This means they have a frequency around 300 kHz (on the lower side of AM radio) - since the speed of light is 300,000 km/s - i.e. a 1 km wave goes by at a frequency of 300,000 times per second. To let us hear the patterns in the signal, they shifted these RF signals down by a factor of 30 or so, and converted them to sound - around 10 kHz.

These RF signals are due to the motions of charged particles (electrons and protons) trapped in the magnetic field of Saturn. As the particles cycle back and forth along the magnetic fields, they move at different speeds and spread out, with different frequencies coming at different times. Converted to sound, it becomes these eerie tones.

The giant planets have very large magnetic fields. The charged particles come from the Sun, and also interact with the moons and rings. Jupiter has an even more powerful magnetic field, and radio bursts indicate that lightning bolts jump the space between Jupiter and the inner moons.

Here is a video that shows a model of Saturn's magnetic field.
The video must be correct, since the narrator has a british accent.

Gogol Bordello - Super Theory of Everything (Live)

MrFisk says...

First time I had read the Bible
It had stroke me as unwitty
I think it may started rumor
That the Lord ain't got no humor

Put me inside SSC
Let's test superstring theory
Oh yoi yoi accelerate the protons
stir it twice and then just add me, 'cause

I don't read the Bible
I don't trust disciple
Even if they're made of marble
Or Canal Street bling

From the maelstrom of the knowledge
Into the labyrinth of doubt
Frozed underground ocean
melting - nuking on my mind

Yes give me Everything Theory
Without Nazi uniformity
My brothers are protons
My sisters are neurons
Stir it twice, it's instant family!

I don't read the Bible
I don't trust disciple
Even if they're made of marble
Or Canal Street bling

My brothers are protons
My sisters are neurons
Stir it twice dlja prekrastnih dam...

Do you have sex maniacs
Or schizophrenics
Or astrophysicists in your family
Was my grandma anti anti
Was my grandpa bounty bounty
Hek-o-hek-o-hej-o
They ask me in embassy!

'Cause I don't read the Bible
I don't trust disciple
Even if they're made of marble
Or Canal Street bling

And my grandma she was anti!
And my grandpa he was bounty!
And stir it twice
And then just add me!

Inside The Sun - A Closer Look At Our Star

Enzoblue says...

This is just way too dumbed down. "Not only is the sun the largest star in our solar system, it's the only one!" WTF

Is this correct?

The shear amount of mass that just makes up the sun is enough to cause that much pressure and heat to begin with because of the immense gravity having a role. If the sun were some significant amount less massive, it just wouldn't cut it.


Yep, that's correct. At the very core there are protons of hydrogen running around and in order for the sun to shine they need to get close enough together to fuse. (this nuclear fusion is the first step in the Proton - Proton chain reaction that converts hydrogen to helium). Since protons are positively charged they repel each other, so you need a lot of gravity to force them together, i.e. bigger sun. (They are repelled by the electromagnetic force and need to get close enough together that the strong nuclear force can take over and fuse them.)

Interestingly enough, the sun still isn't large enough to force them together, but it gets them close enough that quantum tunneling can take effect.

Look this stuff up and get into it. It's very rewarding and you'll be able to explain it to your kids.

Tomorrow, we will be consumed by a black hole (Geek Talk Post)

shuac says...

As I understand it, they're smashing protons which are smaller than atoms.

This uproar reminds me of the Mars convergence back in July 2005: where the sky-is-falling types were screaming about Mars colliding with the Earth. It's so mind-numbingly stupid, that I believe them to be joking. Hence, I think the black hole people are joking too. Pretty funny.

...but maybe not.

We can smash protons together at near light speed in hopes of resolving the grand unified theory, but still no personal jetpacks! I was promised jetpacks! Why not put 8,000 physicists to work on something I can use!

Plasma cosmology - Electromagnetism is the dominant force

Irishman says...

No this is it, this is exactly right. Electromagnetism is matter, you can derive equations for matter, for particles, including DeBroglie waves that quantum physicists completely ignore, from Maxwells equations for electromagnetism.

It doesn't say that Einstein was fundamentally wrong, it says that the interpretation of relativity was wrong, and it was, unfortunately. Einstein said that the more predictions that quantum theory made the sillier it looked. This clip is exactly the line of thinking that Einstein was on, so was Tesla, so was Maxwell, so was Bohm.

You only need two forces for this to work, gravity and electromagnetism. And we have only ever detected those two forces. The mainstream view is that you need four forces, gravity, EM, and strong and weak nuclear forces. Guess what, no matter how big a particle accelerator we build we cannot find those nuclear forces. Every time we build a bigger one the equations are changed and they put the Higgs at a higher energy level. When you try to work them out on paper you need infinite energy to hold the protons together in the nucleus of every atom. They botch the infinities, they normalise them, it's a complete mess.

I'll tell you what's not convincing, dark matter, dark energy, and force carrying particles like the Higgs and the other Bosons. You can derive everything from gravity and EM, you can even derive relativity from the same EM wave equations.

If you want to study something that isn't convincing, you need look no further than the mess that is quantum mechanics and string theory. Many are abandoning the field. Relativity is safer in the hands of the plasma guys than it is with the charlatans of QM and String.

Mini Black Holes and the Large Hadron Collider

deathcow says...

yeah! remember that country song???

What if Jesus came back like that...
A planck sized dot of inifinite mass!

What if Jesus came back like that...
Decayed right away.. and gone like that!

What if Jesus came back like that...
But years too early.. from the proton smacks!

What if Jesus came back like that...
Light speed, burned.. and pissed at Cern!

Hawking radiation

jwray says...

If black holes could be formed by random high energy collisions of particles on a micro scale you would expect black holes to randomly, accidentally, be formed at any time during the life of a star. According to the maxwell-boltzmann distribution, in the core of a red giant, with a temp of 100,000,000K, a few protons per million would be moving at half the speed of light.

It might be the case that black holes don't really exist. That would solve the conundrum of how the big bang could ever have happened without forming an event horizon and collapsing back in on itself.

http://space.newscientist.com/article/dn12089-do-black-holes-really-exist.html

It may remain slightly less dense than what is necessary to form an event horizon, by some quantum mechanical mechanism, but still cause enough gravitational redshift of outgoing light to render it almost undetectable.
