"hot gas"... what is the problem with them using the correct term "Plasma"?

If you want on or off the Electric Universe Ping List, Freepmail me.

Incidentally, atoms at a temperature of 170 million Kelvin will most likely no longer have any electrons associated with the nucleus... they will be shared by the mass of all atoms. A plasma. No wonder they are getting high energy X-Rays.

Boy. I’m sure glad our thermometers don’t go as far as “170 million degrees Celsius”... we’d need some serious sun block for that.

Or has Glob Al been at work again?

Even Al would burn off his lips if the gas coming out of his mouth were 170 million C...

170 M Kelvin is beyond anything I have ever heard of...can there even be protons and neutrons?

Plasma: The other 99.9%

How do you see the Solar System? The simple view is gas giants and rocky asteroids and planets moving through nearly empty space. The sophisticated view illustrated above, shows the heliospheric current sheet, a component of the interplanetary plasma we call the Solar Wind, awash throughout the Solar System.

Over 99.9% of the universe is made of plasma, including the Sun and all stars, and most of the space in between. So if you don’t know the basic properties of plasmas, then you might not understand the properties of most of the universe.

Did you know...

1. Plasmas are formed by adding energy to gas, causing it to ionize (an atom looses one or more electrons). For example, if hydrogen ionizes, it produces equal numbers of negatively charged electrons and positive ions (in this case, protons). Even a one percent ionized gas may be considered to be a plasma, and have the properties
of a fully ionized plasma.

2. Plasmas are affected by electromagnetic forces 1039 times greater than the force of gravity. So strong is its influence that it creates the ballerina’s skirt shaped heliospheric current sheet (see diagram), the largest structure in the Solar System, extending out
beyond the orbit of Pluto.

3. Plasma is not always electrically neutral. In general it is quasi-neutral, meaning that localized regions of charge separation may occur. And objects that comes into contact with a plasma will charge negatively, such as dust, spacecraft and the surface of the Moon.

4. Plasma is a better conductor of electricity than copper. Its conductivity and response to electromagnetic influences distinguishes it from a gas. Indeed, metals can be classified as plasma, too, because they contain free electrons.

5. Moving plasma can self-generate electromagnetic fields.
6. Plasma can store energy in magnetic fields.

7. Plasmas form double layers between regions of different densities, temperatures or magnetic field strengths. A double layer:
(a) consists of two layers of opposite charge
(b) tends to form cellular structures with the double layer as the “cell wall.” (eg. magnetosphere, photosphere, heliosphere)
(c) can form in filamentary current channels known as “Birkeland currents” (see below);
(d) can explode, as discovered in mercury rectifiers used in high-power direct-current transmission lines;
(e) can accelerate charged particles, in opposite directions up to velocities approaching the speed of light.

8. Relative movement of different plasma regions produces electric currents within them.

9. Electric current in plasma produces “pinched” filaments known as Birkeland currents. Birkeland currents form the cosmic power lines and the “wires” of cosmic circuits. An example is found in the ionosphere where these filaments carry up to a million amps, and power the aurora. Those in the Sun’s prominences have been estimated to carry up to 100 billion amps (1011 A).

10. Birkeland currents collimate “jets” of matter and charged particles. Astronomical “jets” were so named by astrophysicists because they look somewhat like fluid jets produced in the laboratory. Yet astronomical jets look nothing like a supersonic jet coming out of a nozzle, with all the attendant fluid instabilities. Heated gas should quickly disperse in space but the magnetic pinch of a Birkeland current can maintain filaments of glowing matter over thousands of light years.

11. Synchrotron radiation from pinched current filaments can be in the form of x-rays and gamma rays.

12. The pinch effect can be used in nuclear fusion reactors.

13. Plasma phenomena scale in size over at least 14 orders of magnitude. So the same phenomena may be seen in a dense laboratory plasma and a tenuous space plasma.

14. Parallel plasma filaments attract one another with a force inversely proportional to their distance apart. Compare this with gravity, which attracts matter with a force inversely proportional to the SQUARE of the distance. That makes pinched Birkeland currents by far the most effective way of condensing rarefied dust and gas to form molecular clouds and stars.

So since the Universe is 99.9% plasma, the important question is not IF the properties of plasma are important in cosmology, but HOW come we focus on the puny force of gravity?

I guess, in plasma state. :’)

Let's make certain Freepers not familiar with plasmas REALLY grasp the magnitude of the forces involved... it's not "1,039 times greater," it's 1039 greater!

That's 1,000,000,000,000,000,000,000,000,000,000,000,000,000 times greater!

it's not "1,039 times greater," it's 10(to the power of)39 greater!

That's the second time I've done that, sorry! Sure looks purdy with all those zero's: 1,000,000,000,000,000,000,000,000,000,000,000,000,000

Two explanations have been put forth to explain this massive explosion: a cosmic collision and a supermassive black hole.

The insert on the last photo looks more like ejecta from the central body rather than collisions.

I've done it, too. It happens when you cut and paste... the HTML tags are left behind.

Plasmas are formed by adding energy to gas, causing it to ionize (an atom looses one or more electrons).

Does it (set) loose one or more electrons, or does it lose one or more electrons (or, IOW, was this piece possibly written by a FReeper)?

(Sound of grey_whiskers purring.)

Thanks for the informative post.

Cheers!

It loses one or more electons.

Glad to help, Ma'am!

Cheers!
