I've personally seen green and pink meteors that my memory at least recalled as being this vivid. I doubt this image was processed any more than any other night landscape photograph would be.

No drinks? Does the surgeon not even get a chance to have someone hold a juice box to their face? Or is that more likely to make them have to unite, which would take them away for longer.

Traditionally the scrub techs and nurses are employed by the hospital, and as such are required to have 2 15 breaks and 1 lunch. They have a float person cover for breaks. Nurses give a brief rundown of what stage they are at and any pertinent medical history or charting stuff. Same for the scrub techs who cover breaks.

The doctors are independent contractors and usually work all the way through a long case. Longest was maybe 8 or 12 hours that I’ve seen. If they do need coverage usually their medical group has someone who they can contact to hand it off. Usually not though 99.999% if times

The nurses and scrubs rotate out for lunch and breaks and shift change; CRNAs too. The surgeons usually will stay in the whole time, no food, no drinks, no breaks. But it’s usually rare to have a case last that long, but I’ve seen poly trauma run longer than 12 hours and some big OMFS cases run long too.

Where's "Father" in your list? And it's only six generations.

The calculations of mass and gravity were calculated By Edwin Hubble around 1932. He showed that The Milky Way had only 1/5th the mass needed to hold the galaxy together. Thus was Dark Matter, or it's theory, born. This doesn't even address the biggest problem with the orbital dynamics of galaxy sized systems.

Consider a solar system. Mercury travels faster in it's orbit than Venus. Venus moves faster than earth, and so on. Predictably, all the planets in our solar system move at a greater velocity than Neptune. Everybody knows this and understands why.

Now consider the galaxy and it's spiral shape. In order to maintain this shape the stars at the farthest outskirts have to be moving much faster that those closer in to the center. This configuration should force the galaxy to fly apart, but it doesn't. the question is, why don't the stars fly out into intergalatic space. Spiral galaxies shouldn't exist and nobody knows why.

What you find is that as you go back, that you have so many great, great, great.... grandparents. So Edward was born 1020 years ago, which is roughly 40 generations. In that time you "should" have had 1 trillion ancestors. Which is about 10 times more people who have ever lived. Because the same people keep turning up on different branches of your family tree. Especially when you get to about the tenth generation.

Essentially we have so many ancestors that as long you have children and they have children. Your line will continue indefinetly and you'll have millions of descendants.
