If I was in a space shuttle or even strapped onto a Delta 4 rocket...Would I see the curveture of the earth at 99,999 feet??? Would I start seeing the bluish-tinge or black atmosphere were you see it at the edge of space?

Also...is there like a chart that can tell me how high and what earth would like at 99,999 feet? I can always look at Google earth...but Im talking about temperatures at that altitude, how dark will it be in that altitude?

From what I recall reading about the SR-71, they would start to see the "black" of space instead of blue somewhere lower than 99,999 feet, but I don't remember any exact number. You would also definitely see the curvature by a hundred-thou.

Simple answer is of course.
You can see the curvature of the earth standing just 150' or so above the ocean. The horizon is very slightly but surely curved. From a mere 35000 or so it is rather obvious if you can see 90 degrees or so of arc. But that is not really the curvature of the earth. It is the area described by the limits of your vision as a function of the earth being curved below you.

Hold a basketball at arm's length and you can clearly see the curve of its edges. Now bring it up 'til it is half an inch or so from your eye. You can no longer see the 'horizon' but you can see a roughly circular area.

It depends on how you define the 'curvature' of the earth. The true curvature is the radius of the planet.

The radius is about 3448 nautical miles.
Distance to the horizon from 99,999' is about 389nm.

So from 45 degrees to the left of your nose to 45 degrees to the right of your nose is an arc of 90 degrees on a circle with a radius of 389nm. That is a distance along the circumference of your visual footprint of of about 611 miles. But this is not a true great circle, it is a small circle centered directly beneath you so the curve seen is almost an illusion.

I think I once did this calculation for 35000 feet and came up with the actual curvature being only 45 feet for the range I could actually see. Over the ocean you might perceive that, but over land the irregularity of the terrain swallows up such a small curve.

In fact, scientists in ancient Greece had already correctly calculated the size of the earth based on when a mast dissapeared over the horizon. This knowledge was then lost for a little while.

If you were standing in the middle of a perfectly level surface, at sea level, looking out at the visible horizon-- it would be a circle surrounding you, right? And a circle is inevitably curved.

So you have to figure out what you mean by "see the curvature". You could reasonably say you can't help seeing it.

If it were perfectly level you would only be hindered by haze. No horizon in the sense we are used to it. Similarly if you were on the inside of a Dyson sphere or a Niven Ring the horizon would be a haze with the ground curving up and over out of it.

In a hypothetical perfect vacuum there would be no haze. On a hypothetical infinitely large perfectly level surface you would see infinitely far. On the inside of a Dyson Sphere or Niven Ring you would simply see the ground curve up and over. At which point you would fall over backwards  Wink

Nope. Freeman Dyson (eminently Googleable) postulated an artificial planet, like a hollow pingpong ball with a star at its center and us living on the interior surface facing that star. No night. Protected from space hazards by the skin of the sphere. Can you imagine how much acreage such a thing would have compared with Earth? Say a radius of 93 million miles from our sun. Someone else can do the math.

Hmmm. That indeed was the thing from Star Trek. Maybe a different episode though....

And here you go (for a sphere with radius 93 million miles, and infinitely thin skin):

69,559,385,250,000,000,000 acres, approximately rounded to the nearest significant digit, as I only know pi up to 3.141592654.

By the way, the phrase "eminently Googleable" has a nice ring to it. Could be signature material (with the author's permission of course )

EDIT: Sorry, I should have been clear - I wasn't suggesting that Star Trek originated the idea of the Dyson sphere; I was just trying to figure out if that was what I remembered.

As SlamClick points out, it was used in a Star Trek TOS episode, but Dyson came up with it way before.


This is where I recommend "Ringworld" by Larry Niven. The quintessential Big Dumb Object story.

Pi fascinates me. Try to imagine pi being another value (say, 5.2). The universe would be completely different.

At the very end of Carl Sagan's "Contact" (the book, not the movie), there is a chapter called "The Artists's Signature". The last section has Ellie, still looking for the truth about the Universe, finding a long string of ones and zeros buried deep within pi. If you lay out these ones and zeros in a square raster in base 11, you get a circle. The interpretation is that the Universe was created, and deep within a physical constant there is a signature, or at least proof of creation.

Speculation, but still raises interesting questions about why the constants are as they are.

Is that actually true? If so, it's interesting. However, what is a square raster?

Indeed, and for any calculation I'm doing, knowing pi to 10 digits is more than enough.

It is not true. It's a fictional construct. That is, it's a fictional series of numbers embedded in pi used by the author to illustrate a point about how a hypothetical creator could leave proof of creation, but only for races that have achieved a high level of technological prowess.

A square raster is in this case simply a layout of sequential numbers in a square. For example:

00000000000
00000100000
00001010000
00010001000
00100000100
01000000010
10000000001
01000000010
00100000100
00010001000
00001010000
00000100000
00000000000

As you can see, the ones form a pattern. In the book, the raster is much larger and the ones form a perfect circle, thus "closing the circle" on the number pi, which has a lot to do with circles.


I can highly recommend the book. Hard science and the search for truth about the universe without being boring or overbearing. The movie was enjoyable, but as usual it's hard to do a good novel justice in two hours on the screen.





And if you want ammo to bash morons who think science is baloney and prefer new age mumbo jumbo (I was kidnapped by aliens and they shoved a *** really far up my *** and since then I feel compelled to *** with farm animals) read this. Includes "Baloney Detection Kit".

Of course I have not read this fictional story-accelerator in context. When I read the The DaVinci Code I kept being amazed by the intuitive leaps taken by a couple of people who hadn't slept in 24-48 hours.

Yes well. Literary license and all that. The raster is not the focus of the novel at all but a sort of nice ending given the rest of it. The more crucial aspects are much better explained and fleshed out.

I found both "The Da Vinci Code of Doom" and "Angels and running around in Rome" very much like fast food. Immensely satisfying for a short while, but strangely not filling in the long run.

Quite honestly, I could name several authors who are more deserving of the title "literary genius" than Dan Brown. He is a only genius in that he has written the exact right novel for the market at the right time. If you read some interviews, you will note this was not a coincidence. He has said that he only read the classics until he tried out a commercial fiction novel (Sidney Sheldon's "The Doomsday Conspiracy"). He then decided that he could do that just as well as they could. Kudos to him for succeeding in a difficult game but it is a bit too targeted for me.

Yes, I am a snob

As for the authors who are more deserving. Highly subjective as always but here we go:
- Peter F. Hamilton.
- Neal Stephenson.
- William Gibson.

I have a weird relationship with Michael Crichton's novels. I enjoy them but always wonder why. Since he is more of a "techie" writer I enjoy him much more than Brown. But his novels always have some things in common:
- Set within a few days. The chapter headings are even "Day 1", "Day2"...
- Filled with buzzwords that are obsolete a year after publication. It was fun to read "Congo" and "The Andromeda Strain" for the camp value alone.
- There's a cover-up at the end.
- There's a bibliography at the end.

It's as if he has a computer program to write them. "Insert buzzword here". Some people have said the same of Clancy. "Insert description of weapons system here".

Very true. I actually think his earlier/middle books were better than the more recent ones. Having read "Airframe", "Prey" and the newer one about eco-terrorism (can't remember the name), they strike me as both 1.) formulaic and 2.) somewhat sloppy (not in writing style, but in plot content, especially tying up loose ends).

Whereas, older books like "Jurassic Park" and "Terminal Man" I very much enjoyed.

Who knows, maybe he's just getting lazy. I probably would too.

Not if the surface is perfectly flat. There would be no horizon. The horizon we are used to is just an artifact of the shape of a spherical body.

As I said before, the only thing stopping you from seeing to infinity on a perfectly level surface is atmospheric haze. In a vacuum you would see infinitely far. Never mind the fact that a perfectly level, infinitely large surface in a perfect vacuum cannot exist in our universe.
