Is There Really No Planet B?

It’s a popular theme in science fiction: the quest for a new Earth, because the old one is becoming uninhabitable, usually due to human interventions. Sometimes the idea is elaborated in a somewhat ironic manner, like in the unsurpassed Dutch series Missie Aarde (Mission Earth), in which the Netherlands take the lead because it’s the only country not under water thanks to its dykes. Sometimes it’s dead serious, as in the movie Interstellar, in which drought, dust storms and crop failures make the need for a new world urgent. Spare world When you realize how much effort it takes to… Read More

The Flat Earth

One of the most bizarre conspiracy theories has to be that of the Flat Earth. There is even a society with hundreds of members who gather at conventions to discuss the “evidence” that NASA and other agencies, with malicious intentions or out of ignorance, maintain the idea that our planet is a sphere orbiting the Sun. But the mere fact that it is not day or night everywhere at the same time suggests that the Earth is not flat. When the sun is shining in Europe, it should be visible from New Zealand as well, on a flat Earth. Even… Read More

A Virtual Forest and One Trillion Real Trees

The World Map of Trees, shown below, is made of more than 15,000 trees that together form the continents of our planet, while the surrounding grassy meadows represent the oceans. A piece of land art on an area of approximately 200 hectares, accessed by roads and paths (the equator and some meridians) and with ditches representing tropics and polar circles. All this of course entirely digital and virtual, because unfortunately I have no backyard of this size. Apart from the fact that this forest map is a nice addition to my collection of world maps (see, for example, the stained… Read More

Space Quotes

This collection of space quotes, cosmic wisecracks and universal oneliners was originally tweeted from the, nowadays pretty dormant, Modified Mars Twitteraccount. I felt they deserved a more permanent location; after all, colonizing the Galaxy is a long term project. Some of these quotes are funny, others are dead serious; occasionally they’re both. They all are, sometimes very obvious, in other cases rather remotely, linked to themes like Mars, spaceflight, astronomy or the universe in general. And since I call this an image blog, I illustrate this page with some space art I’ve produced over the years. “We are all in the… Read More

The Dry Earth: Reversed Terraforming

After terraforming Mars quite a few times, I’ve now done the reverse thing: martifying Earth. What would our planet look like if all the water suddenly disappeared? Like a Pale Yellow Dot, a kind of cross-over between the Moon and Mars. Warming-up No, this is not a warning about the effects of global warming. Those are worrying enough, but in the short term they mainly mean that we have to deal with more instead of less water. Speculation On the other hand: sometimes planets lose a lot of water in the course of their existence. Mars, for example, once had… Read More

A Stained Glass World Map

I have already made quite a few special world maps, but never a version in stained glass. Our planet played a part in the virtual stained glass window that I made of the famous Earthrise photo, but that is not the same. So it was about time to fill this gap in my collection. And here’s the result! Virtual glass The map is made of 1440 pieces of colored glass. Virtual glass, of course, because this artwork was made entirely with the help of Photoshop and a tiny bit of Autocad. Despite the abstraction, the elements that make our world… Read More

The Drowned Earth: 4000 AD, After The Thaw

What would the world map look like if all the polar ice would melt? And how long does it take to get there? These are interesting questions now that climate change is – finally – on the political agenda. And as a cartographer, I could not resist the temptation to visualize the worst case scenario. Gravity When the Greenland ice sheet melts, the sea level rises 7 meters, when the ice melts in Antarctica it causes a rise of 58 meters. So together that makes 65 meters. But that is an average. Because something else plays a role: gravity. Such… Read More

Building a Planetary Road Sign

There must be many of them: those funny signposts that indicate the direction and the distance to places that are usually quite far away. Tokio 9597 kilometers, Kinshasa 6379 kilometers, Mahabalipuram 8106 kilometers. Wouldn’t it be nice, I thought a few weeks ago, if there was a signpost like that showing the directions and distances for the sun, the moon and the planets? Why doesn’t such a planetary road sign actually exist? Of course I immediately knew the answer. The planets all have their orbits around the sun and the moon revolves around one of those planets: the Earth. And… Read More

A Dolphin’s World Map

Once again I have tried to imagine the point of view of one of the other species we humans share this planet with. After the penguins and the moles this time it’s the turn of the dolphins. How does a dolphin mapmaker see the world? Sympathetic and intelligent Dolphins are known as friendly animals. Are they really as sympathetic as they look or are we somewhat misled because their mouths are permanently in the smiley position? I would not dare to make any firm statements about that. Dolphins are also known as intelligent beings. But how intelligent are they exactly?… Read More

The Block World Map Is Here At Last

Yes, my name, Blok, means Block. In fact, the family name was Block until one of my ancestors moved to Rotterdam in the late 18th century and a lazy municipality official dropped the c. In that light it’s amazing that it took so long for me to do something with the block theme. But here it finally is: a Block World Map. Grid The map consists of three grids, which are placed on top of each other. The largest blocks form a grid of 72 by 36; the attentive reader realizes immediately that each block corresponds to five degrees latitude… Read More
