Maybe it’s the music outside the arts centre. There’s something just superb about live rock n roll outside; and not in some distant field; and not in some crowded precinct, but just randomly, below a tree, by the side of the road, with taxis and ambulances and buses going by. The joy is how the rest of the noisy city life is muted. The taxis go by silently as the drums crash away.
Anyway, it’s standing outside under the sky - a rare night sky in Hong Kong - that I start to think about how fast we’re moving through space. How the little warm patch we occupied with a warm Fender amp and joyous noise is long cold space by now. Bear with me if you’ve heard this before, I get like this every 3.5 months, something to do with sunspots or something.
We’re moving pretty fast. In Hong Kong, due to the rotation of the Earth, we’re moving at 1,550kph.
Add to this how fast we’re spinning around the sun. That’s 107,300kph, give or take depending on the time of year, but pretty close.
Oh, and the sun itself is spinning around the centre of the Milky Way at around 869,046kph. Roughly speaking.
And of course, the whole galaxy we’re in is shifting towards Andromeda at a rate of 2,160,000 kph.
Bottom line, amigos, is that we are moving at a little over 3.2 million kilometres an hour, or to put it more manageably, around 870 kilometres per second.
(Now, pedants, please don’t point out that not all these velocities are in the same direction. Sure, at certain times of the day and year and galactic seasons, we could be going as slowly as 328 kilometres per second. But that’s less fun)
Don’t get too attached to that little space you’re occupying right now - in six minutes (up to 18 minutes for the pedants) it will be a moon’s distance away, and likely occupied by nothing but cold vacuum.
That’s if you believe in time at all, which I don’t. It’s just useful for thinking about movement without going absolutely crazy.
Have a beautiful night friends——
it’s an honour sharing space with you :)
