What Does Earth Look Like?


Hey, Vsauce. Michael here. This point of light in the sky is Earth as seen from the surface of Mars. And this is Earth as seen from Saturn. Here’s an image taken only 45,000 kilometres away, the famous Blue Marble. But what does Earth really look like? Well, it depends on how you define “look”. The word look comes from
the old Breton word “lagud”, mean eye, the human eye. And that’s part of the problem.
Images like this are based on light humans can see. But we don’t see everything.
There’s a fantastic episode of Radiolab that uses sound to illustrate just how different other creature visual spaces are from our our own.
When we talk about the way something physically looks we are talking about the visual perception of emitted or reflected electromagnetic radiation. Specifically, visible light. Light we perceive as red has a longer wavelength than blue or violet.
But what if I crank the wavelength even shorter? Does it stop being light? No, it just becomes light you can’t see – ultraviolet, X-rays, gamma rays.
Going the other way, you get infrared, microwaves and finally, radio waves. In principle, the spectrum of possible electromagnetic wavelengths is infinite. But even within the range of wavelengths we observe, the breadth is breathtaking. If the entire practical spectrum of wavelengths was laid out linearly from New York to Los Angeles,
the visual portion we see would only be the size of 100 nanometers. Small enough to slip through a surgical mask. Point is, when it comes to what their is to see, our eyes miss out on lot. For instance, take a look a remote control.
Many of these things communicate with light of wavelengths we can’t see but mobile phone cameras can. Try this at home. Push a button on a
remote control and you won’t see much but use a mobile phone camera
to detect wavelengths you can’t see and have them rendered visible.
There’s a whole lot going on we miss out on. Our night sky is full of frequencies we can’t see with our eyes alone but Chromoscope.net allows you to extend your vision.
This is the Milky Way as we see it, the visible light it gives off. But slide to see how it would look if our eyes
sensed other frequencies. Of course, we are having to represent
these other frequencies with visible colours because even
electromagnetic pretend time is bounded by our puny limits. As for Earth, if we only saw infrared
frequencies it might look something like this in our minds.
Ultraviolet and extreme ultraviolet vision would return
unrecognizable spheres. With X-ray vision auroras around the
poles would shine brightly and gamma ray vision would give
Earth a bright edge from high-energy electromagnetic
radiation hitting the atmosphere at a shallow angle. So, which view is correct? Is there an absolute true appearance of the Earth? We haven’t even started yet. Look back at the Blue Marble.
What’s with the tyranny of “north” meaning “up”? Perhaps, it’s because we often equate “up” with “better” and many early map makers were from
North of the equator. But upside-down maps are equally true, no matter how strange day may seem to us.
Funny enough, the famous Blue Marble itself is a
product of North equals up bias. It didn’t originally look like this. The crew of Apollo 17 originally took it like this. NASA rotated it to fit our traditional idea of up after the fact. Here’s a visual birth that comes from
the US Naval Observatory’s live animation of our planet.
You can see exactly what parts are in its shadow at this very moment.
Other shadows fall on Earth as well, like the Moon’s shadow. Last week @BadAstronomer shared this
image. The dark smudges on the left is actually the Moon’s shadow during a Solar Eclipse as seen from above Earth.
There’s another problem with the Blue Marble – it’s flat and the Earth is three-dimensional.
A globe is the best way to represent the Earth but globes are difficult to carry around
and even when displayed in two dimensions, well, you just can’t see everything at once. A flat map of the Earth is really convenient but requires projecting a globe onto something flat. And a sphere’s surface cannot be
represented on a plane without distortion.
The West Wing famously pointed out the limitations of flat maps. There’s no such thing as a perfect flat map of the entire world. Some maps are useful for some
things and other maps for other things but it is really fun to pick on the Mercator projection, mainly because it’s so popular and is
even used by Google Maps, mainly because it’s so easy to zoom in on. It preserves shape decently well but suffers when it comes to area. As I’ve shown before, Africa is huge. Its area is so large the
entire contiguous United States could fit inside of it, along with all of China, India, Japan and much of Europe. But on the Mercator projection scale near the poles is pretty wonky, distorted, which means Greenland appears to be as large as Africa, even though in reality it is only 1/14th the size. There’s more. Check out Alaska and Brazil on a
Mercator projection. They appear almost the same size but in reality Brazil is nearly five times bigger than Alaska. Areas near the equator are minimized, whereas areas closer to the poles are exaggerated. To have fun with this problem, play the Google Maps Mercator puzzle. The red pieces are
countries projected outside of their usual locations. Now, what the heck is this weird shape? Well, let’s pull it away from
the North Pole, where scale is distorted a lot and now it’s Australia. You can see how the math behind map
projections distort Earth by interacting with them on Jason Davies’ brilliant site. Notice how small
Greenland appears on the Mercator projection when pulled down to the equator and how exaggerated it becomes
when moved to the edge. To be fair, the Mercator projection is great for navigation. If you want something that is more fair
when it comes to area, try the Gall–Peters. Here, landmasses are the right relative size but shape is sacrificed. Everything looks a bit too narrow. Enter the Mollweide. This projection shows equal areas and is a bit more pleasant shape-wise. If you interrupt the Mollweide around
the oceans, relative area is preserved and the shape of land masses becomes even more accurate. When it comes to the shortest
route between two places on the surface of the Earth, Gnomonic projections are really cool. Every straight line journey taken on
Earth’s surface is actually part of a great circle. On Mercator projections actual straight line paths look curved. But every straight line on a Gnomonic projection is also a straight line in real life – the shortest route. If you want a compromise between shape and area,
you might try the pleasant Winkel tripel, which the
National Geographic Society has used for maps it produces since 1998. Or a beautiful butterfly map that could be a ball until it’s
flattened, say, under a pane of glass. The Dymaxion map can unfold to show how nearly connected Earth’s landmasses are. It’s a great way to visualize human migration overtime. It’s quite impressive how far and wide humans have traveled on earth,
but it remains a bit of a disappointment to realize just how narrow our slice of visual perception really is. But don’t feel bad.
This brings us to the story of Julian Bayliss. Yes, hello, is this doctor Julian Bayliss? [ON THE PHONE:] Yes, speaking. Bayliss told me about how
one day, while using Google Earth, he spotted some dark green vegetation. It looked like a rain forest.
An expedition was scheduled and it turned out to be just that – a rain forest we had previously never seen. I asked him more. So, what have you found there? [ON THE PHONE:]
That day we found about 12 new species just from Mabu.
So we found about 3 snakes, 2 chameleons and about 4 butterflies, 2 new species of plants and we’ve only really just been into the
forest edge. So, I read, read a paper the other day, a scientific paper.
They estimate that there’s maybe 8 million, 8.5 million species in this world
but we’ve only actually discovered 1.5 million or between 1.5 and 2 million. So, we’ve actually only discovered maybe one fist of everything that’s living on this planet. Wow, our eyes only see a tiny fraction of what there is to see. But within that tiny fraction there are still an enormous number of things left to find.
So keep searching, keep looking. [ON THE PHONE:]
And as always, thanks for watching.

  23. Ted says:

    1:50 This claim is completely meaningless. What is the "practical spectrum of wavelengths"? Why are we plotting by wavelength anyway? The bandwidth and the maximum data rate of transmission of the visible spectrum are larger than that of the entire practical spectrum of larger wavelengths. I really wish people would stop repeating this claim that the visible spectrum is somehow small. It's just a syndrome of the representation.

    using words like tyranny for Noth = up kills your credibility.. sorry Mr. Stephens. up is the direction that is above your head. if you were hurtling through space that direction would change all the time, as it does in real life because the earth is always spinning, and following the sun. just because northern hemisphere dwellers put a map on the wall in the direction that makes sense for them doesn't make them tyrants. and no up does not mean better.
