Our Seemingly Nearby Sun

[Radrook]

Many persons don't really appreciatye just how tremendously distant our Sun really is because it can be so blistering hot on sunmer days. But in reality, what seems to be a fairly nearby sun is actually an almost unimaginably enormous distance away. Here are some examples to illustrate just how distant our sun really is.

The Sun is approximately 93,000,000 miles (150,000,000 km) or 1 AU (Astronomical unit) from Earth.

Light traveling at 186,000 miles per second takes a full 8.3 minutes to reach us.

Voyager 1 speeding through space ~ at 38,000 mph which is approx 24 times faster than a bullet would take 101 days.

A Boeing 747 at cruising at ~550 mph which would traverse the continental United States in approx six hours would take over 19 years.

A car traveling at 70mph, would take 152 years

A horse galloping at ~30 mph, would take a whopping 354 years l

Walking at ~3 mph, would take you a brief 3,540 years which is almost a thousand five-hundred years longer than the time elapsed since Jesus walked the Earth 2000 years ago.



So whenever at the beach you think the sun is near-think again.

Nobody knows why, but the corona around the sun is much hotter than it's "surface". They have theories, but no total explanation that covers the amount of heating.

One thing that made me appreciate the scale of our solar system has been experiencing it in virtual reality. Even just the distance from the Earth to the Moon is mindbogglingly huge.

The Sun is also frighteningly large compared to the Earth.

Here is one a recent explanation concerning that perplexing phenomenon. According to them magnetic waves are transferring internal heat to the corona.

Light shone on star mystery: Why sun's corona is much hotter than its surface

"Our observations have permitted us to estimate the amount of energy transported by the magnetic waves, and these estimates reveal that the waves' energy meets the energy requirement for the unexplained temperature increase in the corona."

But the possibility does not fully explain the temperature results measured.

Kristian Birkeland and his team knew why the sun's corona is hotter than the surface, and they demonstrated a working model of that phenomenon in Birkeland's lab over 100 years ago.

The heat source of the corona is the kinetic energy of the electrical current that is flowing through that plasma. That same kinetic energy ionizes the Earth's aurora, as well as the aurora of every other planet in the solar system with an atmosphere and a magnetic field.

Based on his working laboratory model of the solar atmosphere Birkeland successfully predicted both types of high speed charged particles in solar wind, polar jets, coronal loops, electrical discharges in solar flares, and a whole host of observations that we observe today in modern satellite imagery of the sun.

It is indeed truly mind-bogglingly huge! Here are some examples of just how large it is:

Its diameter is approx. 864,938 miles (1.392 million km). which means that you could line up 109 Earths across it.

It has a circumference is about 2,713,406 miles as opposed to Earth’s meager 24,000 miles.

About 1.3 million Earths could fit inside the sun.

It has 333,000 times the mass of the Earth.

It contains approx. 99.8 of the solar system’s mass.

So why are other scientists expressing so much confusion over the matter if the cause was clearly demonstrated? over 100 years ago?

I should think the average distance to the Sun is second only to the number of minutes in an hour, in being a well known figure.

 

[Michael]

Well, for starters, most of them have never even read Birkeland's work in my experience, and none of them seem to understand it. The mainstream is unaware of the charge separation that exists between the surface of the sun and the heliosphere.

FYI, Hannes Alfven used *circuit* theory to model all the high energy behaviors of the solar atmosphere, whereas the mainstream uses "magnetic reconnection" in those same places. Alfven called magnetic reconnection theory "pseudoscience until the day that he died, and he's the guy that *wrote* MHD theory.

Talking about how big things are, or alternatively, how small we are... I kinda like this video:

 

[Michael]

This is a side-by-side image of an x-ray image of the sun from the Yohkoh spacecraft (right), with an image Birkeland created in his lab (left) which shows those same 'coronal loop" formations in his working model. It also shows the "polar jets" he was able to replicate in his experiments.

Massive Magnetic Ropes Found to Connect Earth to the Sun

Magnetic Rope observed for the first time between Saturn and the Sun

FYI, we've also recently verified that there are current carrying "magnetic ropes" which physically connect the sun to the Earth, as well as connecting the sun to other planets in the solar system.

Alven described "magnetic ropes" as current carrying "Bennett Pinches" in plasma. From his book Cosmic Plasma:

"However, in cosmic plasmas the perhaps most important constriction mechanism is the electromagnetic attraction between parallel currents . A manifestation of this mechanism is the pinch effect, which was studied by Bennett long ago (1934), and has received much attention in connection with thermonuclear research . As we shall see, phenomena of this general type also exist on a cosmic scale, and lead to a bunching of currents and magnetic fields to filaments or `magnetic ropes' . This bunching is usually accompanied by an accumulation of matter, and it may explain the observational fact that cosmic matter exhibits an abundance of filamentary structures (II .4 .1). This same mechanism may also evacuate the regions near the rope and produce regions of exceptionally low densities."

Could you clarify this, please? Kristian Birkeland died in 1917 - Kristian Birkeland - Wikipedia ; however, I understood that astronomers only realised that the corona had T ~ 1 MK after about 1940, when Bengt Edlén identified the 'coronium' line at 530.3 nm as Fe XIV - Coronium - Wikipedia .

Birkeland was well aware of the sun's corona, although I don't think he knew it's exact temperature. When he turned the sphere into a cathode he began to observe things that he compared to the sun, including comparing that blue colored corona in that video to the sun's corona. Keep in mind that spectrometry was in its infancy back then. I think he discussed "coronium" which was later demonstrated to be an emission line of ionized helium as I recall.

I'm certain however that he would have recognized all the features he observed in the lab with the images of the sun from satellites in space and he would certainly have understood it was an electrical process.

No, the 'coronium' line at 530.3 nm is a line of Fe XIV (iron that has lost 13 electrons).

If the Sun is a cathode, what did it do with all those protons? and, if it has been spewing out electrons ever since, how come it is still a cathode?

That could be.

 

[Michael]

If the Sun is a cathode, what did it do with all those protons? and, if it has been spewing out electrons ever since, how come it is still a cathode?

Based on the "soot" that accumulated on the walls of his experiments, Birkeland actually predicted that both types of charged particles came from the sun toward the Earth. Today we call it sputtering. The high speed cathode electrons slam into ions in the atmosphere and push and pull them out into space. The bulk of the current between the sun and the heliosphere is carried by the cathode rays (today it's called "strahl"), whereas the slower moving particles were mostly "neutral".

The sun is a gigantic generator in Birkeland's model. I'd assume he'd have chosen fusion today as the power source of his model, whereas he called it a 'transmutation of elements" in a New York Times article. I think he was open to fission or fusion, but fusion seems like the natural choice. Like the standard solar model, the sun is generating its own power in Birkeland's model.

I just checked, and you're right about the specific wavelength and the Iron ion.
