im not a geologist or anything but I am guessing at one point the earth was and then with continental drift and land rising it became how it is today. cool thread btw >_>
It already exists.... A long time ago, in a galaxy far, far away. Dac - Wookieepedia, the Star Wars Wiki But in reality, we think we may have already found one such world in our own Galaxy; http://en.wikipedia.org/wiki/GJ_1214_b
Rip tides are only found on shorelines, so on a world of just giant ocean, no, there wouldn't be rip tides. The strength of the tides in general would be determined by the number and mass of the satellites.
to get waves and shit you need a moon and not every planet has a moon so you gotta think about that shit...why the fuck am i talking about this ..fuck we all high XD
You mean Europa. And it's pretty certain that there is a planet, umm, moon-wide ocean of H2O under the miles thick ice-layer that covers that jovian hunk of rocks. And there is massive tides, as the gravity of Jupiter pulls and tug on it. Thus the plentifull cracks in that massive ice-layer.
I was thinking, what if there was a hugely massive planet, like say 3 times bigger than the earth, but it rotated say five times faster than the earth does, would that result in less gravity felt overall? as the centrifugal? force counteracts the planets gravity?
Technically yes. But it would be so neglible that it would hardly be measurable. You don't feel any momentum in any direction now, do you? Yet assuming you live in a temperate zone (as opposed to polar or equatorial) you are wizzing around the axis of earth at between 800 to 1400 km/h (500 to 900 mph). Not to mention orbiting the sun at 10700 km/h (66,600 mph) or so about. No one is at the current tail end of the earth hanging on for dear life
Yeah for sure I was just thinking of the implication of having a larger planet than earth would have on life the gravity would be a very big drawback. Take insects for example, if they're exoskeletons could withstand earths gravity better they could feasibly become much larger. I was thinking a larger planet might result in more meteor impacts but in the light of panspermia theory, it might work towards greater diversity of life Having a more massive planet would also mean that when its inhabitants understood concepts like rocketry and escape velocity their escape velocity would have to be bit bigger and perhaps that would slow down their pace of technological advancements On the other hand having a larger mass might result in having more moons and those moons may serve as shields from interstellar threats I just like to wonder weather earth is really the Ideal environment for fostering a technologically advanced civilization...perhaps more water, more gravity, different atmosphere, different radiation all of these things could play a factor on what kinds of other advanced civilizations are out there
Life adapts to its surroundings. So reasonably, higher gravity would lead to more sturdy animals. They would need more solid bones, and more muscle. Also flight may not be that common, ofcourse, more gravity would also lead to a thicker athmosphere, but still. And you'd not see very tall trees, or equivalent. The reverse is true for planets with less gravity than earth. Taller thinner creatures, possibly giant, well, big, exoskeloton ones. Hard to predict specifics naturally. But I am sure we will find advanced life somewhere, sometime, and then we can begin to compare with real world data
