Preflare and postflare seems the same... I think that is something periodical or of impuls character... Is there a danger increasing level of radiation of any range down to The Earth?

It is a measurement of both. No?

No. It is a unit of distance.
Like a foot. Like a yard. Like a mile.

Sorry, my math is a bit fuzzy. I'm definitely not a mathematician nor physicist.
I thought that since a LY = d/t, then t = d/LY

LY = 9,460,887,210,432km / 31,558,118.4sec = 299,792.5km/sec

So 31,558,118.4sec = 9,460,887,210,432km / (299,792.5km/sec)
31,558,118.4sec = 31,558,118.4sec
which = 1
1 what?

I had to work it out for myself and see that the units cancel out. Jeez, I gotta hit the books again, heheh!

That's the problem. That is a simply a rate, in this case the speed of light. You have not included the duration (1 year). The correct formula is LY = d/t * t. That leaves you with d.

1 what?
One unit of distance. If calling it a lightyear is confusing call it a meeblewarp. One meeblewarp, the distance light travels in one year.

Solar flares will normally mess with our radio waves.

As an example, back when I lived in Colorado back in the 80's, I remember picking up radio stations on the FM dial all the way from Chicago and New york.

At first they would start to fade in, sometimes they would be strong enough to wipe out our local stations, but after about 2 minutes would fade out again. Then the cycle would repeat minutes later.

Even more accurately, a light year is a calculated distance based on our best ability to measure the speed of light over a relatively tiny distance, in an extremely tiny amount of time.

I did a little search, and it seems that the measurement of the speed of light has not been done in space.

math.ucr.edu...

www.lagrange.edu...

I would have thought that by now, an experiment would have been conducted with some deep space probe to actually measure the speed of light in space. We are not able to duplicate the vacuum of space in a lab. It seems that it is very possible that light moves at a very different speed in actual space, and we don't even have a clue about the nature of space outside of our sun's heliosphere.

Heck, even our calculations of the distances to the stars is pretty shaky, and in reality involves a whole lot of guess work.

We know that light speed changes depending on the media it moves through. Do we know how plasma effects the speed of light, being that we have a huge plasma sphere that surrounds our planet?

Light could be getting here from other stars a whole lot faster than we realize.
