The essential difference is that Earth has an atmosphere and the moon doesn't. Every kilogram of the moon's mass is opaque, and casts an umbra shadow that is completely dark, with the exception of the light from the sun's corona. The Earth by contrast has atmospheric optics that come in to play, which scatter the blue light to form your blue sky, and refract the red light toward the moon in the umbra. It is all the worldwide sunrises and sunsets that are simultaneously illuminating the lunar eclipse. If we had a moon like Titan that had its own atmosphere, we'd get lit with red light during its solar transit just like what happens on our moon during the lunar eclipse.
If we had a hypothetical moon that were 4 times as far away as the real moon, what would an antumbral lunar eclipse in the shadow of the Earth look like on it?
If that where a true scenario, the moon wouldn't fall into the antumbral shadow of the earth, instead, the moon would fall into the earths umbral, or penumbral shadow, but the earths umbral shadow would appear smaller in diameter than the moon, in which case an annular lunar eclipse would occur, (when the umbral shadow of the earth appears smaller in diameter than the moon, due to the distance between the celestial bodies.) The eclipse at maximuim would look mostly dark with a ring of moonlight still visible since not all of the moon is being covered by the umbra. And if the moon ever got so far away from earth in which it falls into the earths antumbra shadow, the moon would just appear dimmer than usual.
These three were used in Griswold v. Connecticut, 381 U.S. 479, 85 S. Ct. 1678; 14 L. Ed. 2d 510; 1965 U.S. LEXIS 2282 (1965). United States Supreme Court Associate Justice, William Orville Douglas, used the three to describe how the United States Constitution FURTHER protects privacy!!!! Great Court Case!!!! Forgot to add. Though the court case was about contraceptives, it, like many court cases, tells more than the specific topic of the court case. Again, the CRUX of this case was about privacy under substantive law!!!!
carultch Like many cases, a lot. Justices themselves have said they use penumbras, umbras, and antumbras method to see beyond the laws on the surface, and look at the laws that are hidden behind the light. Again, those are the penumbras, at umbras, and antumbras. The a Griswold v. Connecticut was one of the best examples of using all three. People seem to think that a court case, like this for example, dealing with contraceptives, can only deal in matters of birth control. WRONG!!!! The justices, using the First, Third, Fourth, Fifth, and Ninth (my favorite one) Amendments in this case, they ALSO said, like a search and seizure, all involve one’s PRIIIIIIVACY on some level. Therefore, all of the said amendments apply. However, they should have also used the Tenth Amendment.
@@bryonwatkins1432 Ok, so what you are saying is the terms penumbra, umbra, and antumbra are used metaphorically, when relating SCOTUS cases to one another. When one case creates a precedent for future similar cases.
carultch When you say metaphorically, that means not applicable. If you’re asking me if those terms are not, i disagree. The reasons are one, I’m merely quoting what the justices said, what they used to come to their majority decision. Two, i do agree with it since they are using Judicial Review versus deciding a political question, trying to see what else is behind the light. Again, the penumbra, atumbra, and penumbras to say how a woman’s body is privacy to which they are right. Frankly, even in 1965, it should have never been a question in any court. Lastly, this case, if one wants to use the part referring to how privacy is looked at, yes, this can be precedence. When i bright this scenario up to my Federal Rules of Evidence professor, a retired judge a few years back, he liked it. OH, i believe what Justice Black (dissenting judge) said about privacy is stupid, but oh well. And Justice William O. Douglas his was perfect.
@@bryonwatkins1432 What I mean by metaphorical, is that the term umbra/penumbra/antumbra is used in a context that isn't about actual light sources, obstructions, and shadows. As an example, you might say that a suburb is "in the shadow" of a big city. It does not necessarily mean that the suburb is in the actual shade cast by the city's skyscrapers. It is a metaphorical statement, about the proximity of the suburb to the city, and the influence the suburb gets from the city.

The wave of financial distress flooding China’s corporate sector, which has seen a furious selloff in bonds following the unexpected default of several state-owned enterprises, is spilling over into a key financing conduit used by China's giant shadow banking sector - the trust industry. As Caixin reports, Huaxin Trust Co. one of 68 companies licensed to conduct trust business in China and one of the largest "shadow banks" in the mainland , is trying to raise as much as 6.8 billion yuan ($1 billion) from strategic investors as it faces a growing liquidity squeeze that’s already forced it to skip repayments on dozens of investment products over the past few months.
If rays from the sun are parallel, then eclipses do not cause two shadow types. (umbra, penumbra) If rays do come in at all angles, then the Eratosthenes test and the belief that we can test the earth rotundity in the same way are out! Only one of the above can be true and whichever stays means the other “fact” must go... So think about it which one must go? The earth is flat and stationary
really rays come in tangent to the sun in all locations. Since the sun is circular, when all tangential rays are shown, all rays have a partner that is parallel to the ray in question. They come in at all angles, yes. But when you question one single ray, it has a partner that is parallel to it on the opposite side of the sun.
Im just here cause of destiny, dont mind me
So i was trying to understand through words from last 10 min and you made it easy just in 2 minutes. Wow
Thanks
Thank you for the concise information, this will be very helpful for my dnd campaign
If the earth or moon is in the umbra, you get one of three results? How can you get three results from the two options of what is in umbra?

Same dude. If it's umbral, then we can't see anything, it's a black total eclipse, correct?
This helped! Thanks man.
oof i feel u got it wrong there-
If we had a hypothetical moon that were 4 times as far away as the real moon, what would an antumbral lunar eclipse in the shadow of the Earth look like on it?

I’m here because of destiny 2
How does a shadow block a source of light? Every tried to eclipse a lightbulb?
How does the moon cast a shadow smaller than itself? I didn’t hear anything about that.
Interesting.
Penumbral Lunar Eclipse will happen this June 5-6 2020
Except the helio centric model has the sun at such a distance that the rays are parallel.
