    Writing: Input Wanted Great Lakes Earth Map

    This is for an alternate history textbook that will serve to be a blueprint for the stories I have in mind. I can't cut it down because everything is connected. And the reason I keep posting this to other forums is so I can find answers and, eventually, a pattern, because if the world is not...

    Writing: Input Wanted Great Lakes Earth Map

    Dark brown=mountains. Light brown=uplifts. Black=Igneous provinces still visible today at their original extent with no consideration of erosion. Let us say that, in the future, some scientists have created satellites capable of something that seems science fiction for now — punching the walls...

    Writing: Input Wanted An Alternate to the Siberian Traps

    If that is all, then it is an alternate history textbook meant to be a blueprint to stories set in that world (in the same vein that our myths and fairy tales are set in our world.) Do you know the answer to the provided question?

    Writing: Input Wanted An Alternate to the Siberian Traps

    Is it necessary to quote the whole thread? It's for an alternate history textbook, but I won't focus on polishing the history until I have the Cause & Effect verified. I've created the Cause, but I don't know the Effect. Also, the title is "Alternate Siberian Traps", not "Alternate to the...

    Writing: Input Wanted An Alternate to the Siberian Traps

    Back home, the catalyst for the worst biotic catastrophe in the world, the Siberian Traps, don't have much left. 252 million years of erosion have reduced the igneous province to a pale shadow of its former self. From 60 to 43 million years ago (not 252), a series of flood basalt eruptions...

    A Series of Exoplanets in Our Solar System

    In this alternate universe, Earth is the same as back home--8,000 miles wide, 25,000 around, six sextillion tons, orbiting a G-type main-sequence star from a distance of 93 million miles. But here, the similarities end. MOON DIAMETER--3,273 miles MASS--0.025x that of Earth DISTANCE FROM...

    Writing: Input Wanted Eleven Inner Planets--What Will Earth's Ice Ages Be Like?

    The mass was what I got from Ganymede, which was dividing Earth's weight by 40.5, which is half that of our moon. It's said that Ganymede has twice the moon's mass.

    Writing: Input Wanted Eleven Inner Planets--What Will Earth's Ice Ages Be Like?

    A Milankovitch cycle is defined in Universe Today as "a cyclical movement related to the Earth’s orbit around the Sun." There are three elements to a Milankovitch cycle that affects the amount of solar heat and with it, the Earth's climate: Eccentricity (Orbital Shape)--The elliptical shape...

    B E=0. What Does That Mean for the Seasons?

    Currently, Earth's eccentricity (orbital shape) is 0.0167086. Zero is a perfect circle whereas One is parabolic escape orbit and any greater becomes a hyperbola. And in the theory of the Milankovitch cycles, Earth's eccentricity varies between 0.000055 and 0.0679 over a period of 100,000 years...

    Great Lakes Earth (WHOLE)

    One answer to your questions. And another. For now, let's focus on the questions presented in the thread.

    Great Lakes Earth (WHOLE)

    The geography of Great Lakes Earth, and the questions that come with it. Pangaea From 250 to 200 million years ago, all the continents had joined together to form a singular landmass called Pangaea. The brown lines presented in the map are mountain ranges varying in height above sea level...

    I The Largest Air Burst on Earth

    "Space bomb" is any body from space that detonates on contact with Earth, be it on the surface or the atmosphere. If you want to be conversational, be general. "Meteor" and "meteorite" won't do because such changes in name implies a change in mechanics and chemistry, which there really isn't.

    I The Largest Air Burst on Earth

    On June 30, 1908, the remote Siberian region of Tunguska made headline news when an explosion knocked down 80 million trees in an area of only 770 square miles. The mystery was that there was no crater, which led to the assumption that the space bomb responsible for the catastrophe detonated in...

    Writing: Read Only Great Lakes Earth

    From Space The first difference between our Earth and Great Lakes Earth can be seen from space. Great Lakes Earth is still the third planet of the solar system, 93 million miles from the sun, 8,000 miles wide and weighing in at six sextillion tons. But that’s that. Back home, the moon has a...

    Back home, the average depths of the world's oceans--and the Mediterranean Sea--are as follows: Atlantic--3926 meters Pacific--4028 meters Indian--3963 meters Arctic--1205 meters Southern--4500 meters Mediterranean--1500 meters In this alternate Earth, the average depths are as follows...

    Altering the Milankovitch Cycles

    As I understand it, the Pleistocene ice ages were dictated by three major factors suggested by the Serbian geophysicist Milutin Milankovitch--eccentricity (orbital shape), obliquity (axial tilt) and precession (direction of rotation in relation to fixed stars). The one identical factor between...
