Here is what we know of Earth: Mass: 5.972 sextillion metric tons Diameter: 7,917.5 miles Density: 5.51 grams per cubic centimeter Rotation: 24 hours Revolution: 365 days Core: 760 miles wi...
66 million years ago, the dinosaur empire was in its death throes when its final nail in the coffin came hurtling down from the sky. A clump of rock the size of Mount Everest smashed into the Gulf ...
Recently, I found this map of Africa's paleolakes in the Imaginary Maps reddit: Finding this map was mere coincidence, but this map definitely interests me. Now there have been multiple what-if...
Allow me to present Lyr, one of a handful of worlds crafted by artist Chris Wayan: The one detail among a vast many that is important to this question is that its salinity is about 1.5%, roughly...
In my last question, I have asked on how, once Mars has been terraformed, Terran species of plants and the insects on which the majority of them rely on would adapt to Mars's longer year. By far, ...
If we humans are serious about terraforming our famous neighbor, Mars, then the terraforming process would take thousands of years before it becomes habitable enough for humans to live in. But tha...
In an alternate universe, we have a spot in the Orion Arm where we have nine Earth-like planets orbiting three red giants. Judging from the size and luminosity of each star, it's been conferred ...
In this alternate Earth, the axial tilt is still leaning to the extent of the temperate and polar zones having four seasons--spring, summer, autumn and winter. The one key difference is that each ...
It's a basic fact that most plants need sunlight to generate growth. Sure, they also need water and nutrients, but their reliance on sunlight is the one sole thing that separates them from animals...
In real life, humans get pregnant for only nine months. Once born, the baby has a long way to go before it can stand, walk and talk. But don't tell that to Mwindo! The African saga of the hero M...
In an alternate universe, the nine realms of Norse mythology--Midgard, Asgard, Vanaheimr, Jotunheimr, Alfheimr, Hel, Nidavellir, Niflheim and Museplheim--are actual, real-life "Earths", in the sens...
So I just got back from watching an episode of the Science Channel program Unearthed, a show focusing on archaeological discoveries. In the episode in question, the subject was on the Lighthouse o...
In this question, we're looking at a humanity that has adapted one of the most conspicuous ways of keeping cool--larger ears. Desert animals usually have larger ears to have more room for blood ca...
The established fact is that the shape of a planet's continental coastlines is determined by the planet's climate. Higher temperatures mean less ice, which ultimately means higher sea levels. (Ca...
Long ago, I asked a question on how to make possible turning the nine realms of Norse mythology--Midgard, Asgard, Vanaheimr, Jotunheimr, Alfheimr, Hel, Nidavellir, Niflheim and Museplheim--into nin...
In this solar system, there are three K-type main sequence stars, or "orange dwarves", named Odin, Vili and Ve. At the center of this solar system, Odin is 80% the mass of our sun. The middle sta...
Earth's deepest point, the Challenger Deep, is almost seven miles below sea level. By contrast, Europa is smaller than even Earth's moon, yet its oceans are anywhere between 40-100 miles deep! So t...
For visual reference: Apes are visual species who rely more on their eyesight than any of the other senses. As a result, they see the world in three shades of color, whereas other mammals see i...
Right from the beginning, the xenarthrans--armadillos, sloths and anteaters--have been at a disadvantage. For the longest time, their home was an island continent, which made them extremely vulner...
Long ago, I asked a question on how to make the Nine Realms of Norse mythology--Niflheim, Muspelheim, Asgard, Midgard, Jotunheim, Vanaheim, Alfhiem, Svartalfheim and Helheim--a reality in regards t...
Recently, I came across an inverted world map on the MapPorn Reddit made by MChainsaw. "Inverted" as in, the "continents" are now below sea level and the "ocean floors" are high and dry. (Conside...
Let's say that some Oriental emperor had decreed that he should move his palatial residence from China to Everest. Specifically, he wanted Mount Everest to be his palace, which means hollowing the...
To put this title into context, there are actually two basic kinds of angiosperms on Earth, showing here: These differences in characteristics serve their own adaptations to survive and thrive. ...
66 million years ago, the dinosaur empire was in its death throes when its final nail in the coffin came hurtling down from the sky. A clump of rock the size of Mount Everest smashed into the Gulf...
Here is the scenario: A Paleo/Mesozoic mass extinction wiped out 96% of all terrestrial species, and the only plants that survived were as follows: One genus of conifer One genus of cycad One ge...
