There may have been other threads, wondering about the mystery of Venus. Or to sum up:

I figured out an idea that may logically account for all four of those enigmatic features. But it requires some thinking out of the box. Anybody ready for debunking me?

There seems to be some explaning to do here for the boldface. We have some tidal - gravity lock mechanism that may have caused that rotation stop, but we may need a asteroid impact to slow down the planet first. There may have been a runaway greenhouse gas mechanism for the extreme temperature but what can cause a complete resurfacing of the planet? Acne redecorating limited?The atmosphere consists mainly of carbon dioxide (the same gas that produces fizzy sodas), droplets of sulfuric acid, and virtually no water vapor - not a great place for people or plants! In addition, the thick atmosphere allows the Sun's heat in but does not allow it to escape, resulting in surface temperatures over 450 °C, hotter than the surface of the planet Mercury, which is closest to the Sun. The high density of the atmosphere results in a surface pressure 90 times that of Earth, which is why probes that have landed on Venus have only survived several hours before being crushed by the incredible pressure. In the upper layers, the clouds move faster than hurricane- force winds on Earth.
Venus sluggishly rotates on its axis once every 243 Earth days, while it orbits the Sun every 225 days - its day is longer than its year! Besides that, Venus rotates retrograde, or "backwards," spinning in the opposite direction of its orbit around the Sun. From its surface, the Sun would seem to rise in the west and set in the east.
Earth and Venus are similar in density and chemical compositions, and both have relatively young surfaces, with Venus appearing to have been completely resurfaced 300 to 500 million years ago.
The surface of Venus is covered by about 20 percent lowland plains, 70 percent rolling uplands, and 10 percent highlands. Volcanism, impacts, and deformation of the crust have shaped the surface.
