I got my glasses a few days ago, so I'm good. Monday is getting close and the 90+% that I will see here is scheduled for 10:14 A.M.

Lucky! Using a tool "Vox" put out, I'll be seeing around 66% at it's peak. Still pretty good, but nowhere as good as up in Washington

Default Re: goggles for eclipse?

If I were a couple hundred miles south, I'd be seeing a total eclipse. I'm happy to see what I will get to see here. It has not rained here in almost two months. Watch it be cloudy out on Monday.

Default Re: goggles for eclipse?

Might rain. You never know. When they were trying to use a total solar eclipse to prove/disprove Einstein's theory of relativity they had to go back and do it another time because the weather blocked out the many groups first attempt. The idea was to see if the stars around the sun had moved position because of the gravity of the sun on their light reaching earth. It was later proved to be true this way, but not by the many groups doing it on the first try. Even then, there was only one or maybe two that got a good enough clear sky to photograph the event.


Edit: This is totally from memory, so if there was some part I got wrong, it is because of that. This did happen though.

Default Re: goggles for eclipse?

Gravitational lensing, If Einstein's theory was right they should be able to see a star that was known to be behind the sun because such massive objects as the sun create enough gravity to warp spacetime that bends the stars light around the sun and lets the star be visible before it should be......

Yeah you basically got it.. IIRC.

I saw a documentary on that light warping
experiment done by a scientist that went
to some far off country to observe the effect.
Was so long ago I can't remember all the details
but he did prove Einstein's theory as fact.

Just found this informative link....

Default Re: goggles for eclipse?

Two or more "teams" were racing to be the first to successfully conduct that experiment that would prove Einstein's theory was correct or not and there was bad luck to go around like getting scientific equipment confiscated and being detained for suspicions of being spys, If i remember it correctly ?

It was during WW I and it was not a good time to be traveling all over the world with a lot of equipment to photograph this event. Many people were detained as spies.

Just found this informative link....

Another one I find fascinating is "Einstein's Cross".
This is where a quasar is G.lensed around a galaxy that sits directly in front of it yielding four images of the quasar around the original image of the quasar.
Check it out, it's amazing.

For God did not send His Son into the world to condemn the world,

“He who believes in Him is not condemned;
but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.
And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil.
For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed.
But he who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God.”
(John 3:16-21)

More gravitational lensing only in that case it's the gravity of an entire galaxy that creates the much larger gravitational lensing and creates four images of the quasar (a active supermassive black hole at the center of a galaxy) that is behind the lensing galaxy...

That is a nice one, Andrew. I have also seen two images of a galaxy lens around a closer one, too. There are many examples of this type of gravitational lensing.

Yeah. Unfortunately it seems like we have only the Hubble Telescope to see them. Well, I guess there are others too, but not for us poor slobs.
