OftenWrong Posted February 19, 2021 Report Share Posted February 19, 2021 I am a Venusian observer, whatever that means. Actually I shouldn't say that, I love all the planets equally. Yes even Pluto after what they did... bastards. The Soviets sent a few probes to Venus. None of them lasted very long. If I recall, surface temperature 800 degrees. Atmospheric pressure on the surface of the planet was very high, and full of hydrochloric acid. A fascinating place. Somehow Russkies landed two Venera probes on it. Both probes survived for an hour and were able to send back some photographs, then went silent. The Venera probes had detectors to "listen" for the sound of thunder in the atmosphere. Signals were detected at 100 hz, possibly indicating the presence of lightning. Also interesting about Venus is that the temperature of the upper cloud deck is at 20 Deg. C, and the chemistry could make it suitable for life to exist. 1 Link to comment Share on other sites More sharing options...
OftenWrong Posted February 19, 2021 Report Share Posted February 19, 2021 Also exciting was the discovery of Neptune. After planet Uranus was discovered, its orbit was found to be unusual and astronomers became aware that there was something inconsistent with their calculations. The existence of another planet was speculated, as that would explain the errant behaviour of Uranus. One of the pencil-necked geeks of the time calculated the position of the planet. By then they had telescopes good enough to see Neptune. And lo and behold, pointed to where they thought and there it was. Found by human reasoning and mathematics. Thank you Isaac Newton. 1 Link to comment Share on other sites More sharing options...

In Orbiter, attempts to land on Venus can be funny as the math starts to breakdown the nearer the surface you get. Sixty atmospheres or something crazy like that. Like flying through Jello...minus Bill Cosby. 1 Link to comment Share on other sites More sharing options...

If Neptune had been on the other side of the sun its gravity would not have affected Uranus. I think the orbital periods are so long, such alignments only occur on the order of centuries. 1 Link to comment Share on other sites More sharing options...

The Great Year is estimated to be around 25k to 30,000 years before everything above us resets. The sheer amount of recorded historical data to be able to calculate that is inhuman. There are only 2 ways that that any of our astronomical public knowledge can possibly exist: 1) The earth is ridiculously old beyond belief and all astronomical historical recorded data has been preserved during all of that time; or 2) divine intervention. Where is all of the recorded astronomical data? Who has been preserving it?? On 2/18/2021 at 11:34 PM, OftenWrong said: I am a Venusian observer, whatever that means. Actually I shouldn't say that, I love all the planets equally. Yes even Pluto after what they did... bastards. She holds the key to our astro-geometric reality from the ground looking up. Without her trajectory, none of the "mathematics" you hold so dear would be solvable. In caveman's terms, we would not be able to tell whether the moon orbits us or the sun. Venus ties all of the mathemagical physics together to prove that the moon orbits us as distinct from it orbiting the sun or the sun orbiting the moon. Although my eye-sight is not very good, I believe I saw venus swing by at night during the summer. I enjoy watching them wandering stars rush past the constellations. Last summer, there were 2 bulbs flipping at the south/half-way point of their trajectories. Looking out the window is better than wide-screen television ever will be! I would be too chicken-shit be it yesterday, tomorrow or today but what do you think motivated the Apollo 7 crew at their time? Were they misled into a false sense of security? or were they simply stooges with a death wish?? Link to comment Share on other sites More sharing options...

The universe is a database. 17 hours ago, Charles Anthony said: Venus ties all of the mathemagical physics together to prove that the moon orbits us as distinct from it orbiting the sun or the sun orbiting the moon. Yes, Venus provides facts for which men have killed, and will kill. Archeo-astronomy is a fascinating field of study that hints at how we developed the very origins of human mythology. There's a Greek play taking place over our heads, with heroes, villains, monsters and beautiful women who need to be rescued. Twelve full moons, twelve months, twelve constellations, 12 apostles. Yet is is well before the Greeks that this play was written and realized. Neolithic man observed these patterns and used them to rise from a feral state to create agricultural society. By observing where the sun rose each day, Ook, placed a rock in that spot and waited for the next dawn. Ook counted 360 rocks, Hence the circle has 360 degrees, and some ancient calendars are based on 360 days. Plus a few days thrown in for religious festival, to sort things out. Christmas trees and Milky Ways. 1 Link to comment Share on other sites More sharing options...
Charles Anthony Posted February 23, 2021 Report Share Posted February 23, 2021 How do you guys define space "history" as distinct from fairy tales? What pivotal event would you say defines when space history starts? I want to distinguish what is seen from the ground with what is seen/discovered from space exploration.

You would have to make a long and narrow slit to allow the light to pass through very precisely. If the ground heaved you might be screwed up, so make it a really big rock.

They aligned their buildings to the stars. So I would say space history starts when human history does. Probably went back before that, we don't know what they knew back before about 5000 years ago. The same curiosity and ingenuity is what drove their interests back then as now. Mythology is a living force that still exists today.
