• The other day I did this video about time dilation, or the idea that time is relative to your

• current speed, but that got me to thinking: there's no such thing as not moving!

• You might think you're just sitting there, watching this video, maybe you're in a car,

• on a train or even on an airplane. But even if you were at home on your couch trying to

• be as still as possible, you're still traveling XXX,XXX miles per SECOND. EVERY SECOND. Sit

• still and think about that for a second

• The questionhow fast are we moving?” is FAR more difficult to answer than I thought

• because there are so many moving parts -- literallypun intended. So, let's go through each level

• of motion and then add it all up at the end.

• Starting small, you're not moving. Just to keep it simple, you're standing still on the

• equator. As the Earth rotates, the equator is going the fastest, and the poles are going

• slowest. If you were standing right on the north pole, you'd simply rotate once every

• day, but on the equator, you're going about 1,000 miles per hour (1600km) in a circle,

• every day. You don't feel it, for the same reason you aren't stuck in your seat while

• a plane is flying, speed is relative, you only feel it when it changes. So anyway, you're

• already going 1,000 MPH AS A PERSON.

• The Earth is traveling around the sun, once per year. It's a trip of 584 million miles

• (942 M km) to get the sun back to the exact same point in the sky. That means, the whole

• planet is flying at 66,667 mph (107k kph) AS A PLANET! Then, zooming out further, we

• are ALL tied to the movement of the sun. The sun is flying through the galaxy with all

• of us planets tucked into its gravity. Scientists determined, the sun is moving toward other

• stars at around 45,000 miles per hour (72,420kph) but we're ALSO moving "up" relative to our

• galactic disc at about 15,700 miles per hour (25.2k kph). We're not going to fly out of

• the galaxy, the gravity of all those other stars is going to slow us down and pull us

• back in over the next 14 million years. AND since we're about halfway out of the center

• of the Milky Way, and as far as we can tell the galaxy rotates once every 200 to 250 million

• years; we're moving approximately 550,000 miles per hour AS A SOLAR SYSTEM.

• We're not done yet either! You, the planet, the solar system andThe MIlky Way. Our

• galaxy is heading toward the Andromeda galaxy at a pretty good clip. Numbers vary, a recent

• 2013 Space.com[a] piece clocked it at 252,000 miles per hour. Again, with the three dimensional

• thinking, the Milky Way is ALSO moving toward the constellation Hydra at about 1,342,000

• mph (216M kph) and toward Virgo at like half that. So overall the Milky Way MIGHT be traveling

• as fast as 2,237,000 mph (3.6M kph).

• Another sidebar: the further away from YOU that you get, the more difficult it gets to

• measure your speed. The reason we use constellations and other galaxies is the same reason we use

• trees or mountains here on Earth to gauge distance. They're large and far enough away

• that they become a point of reference. We can measure our SPEED relative to theirs,

• but of course, all the stars and galaxies in Andromeda -- like a mountain -- are moving,

• Andromeda is moving, the stars of the constellation Hydra -- like the tree -- is movingEVERYTHING

• IS MOVING.

• AND the whole universe might be moving. Yep. The whole damn thing. I can get into that

• if you want! Lemme know with a like and if we get to 10,000, we'll come back to it. It's

• big, y'all.

• Now, to the MATHS!! Your 1,000 mph, plus Earth's 66,667 mph, plus our system's 550,000 mph,

• plus the galaxy's 2,237,000 miles per hour equals = about 2,855,000 miles per hour or

• about 800 miles every second. Think about that. That's mind-boggling, and incredible.

• The reason you're not clinging to the ground in fright is because again, speed is relative.

• YOu're not feeling it because we're all on this supersonic jet together. Us, and all

• the stars in the galaxy.

• How does all this make you feel? Small? Tiny? Insignificant?! Or super amazing and important!

• There's WAY more to this than this simple video is going to explore, but if you're like

• me, this video gave you some feels. Express yourself! Go on!

• We'd like to take a moment to thank Subaru making this big thinking video possible and

• for keeping us in motion.

• Especially the all-new 2015 Subaru Legacy. Every sedan has its benefits, but only one

• combines them all. It’s not just a sedan. It’s a Subaru.
