We are curving,
avoiding life’s black holes,
skipping star-encrusted puddles,
bending light through space and time,
taming swirls of cosmic inky rhyme,
producing poetry of gravity,
Kim M. Russell, 30th October 2018
Björn is back to inspire us – or scare us – with physics. He reminds us that we covered the theory of special relativity a while ago, which resulted in some cool poems. This time he has focused on the general theory of relativity and Einstein’s prediction of gravity as curvature of space-time.
He explains that, since light has no mass, we would expect it to be unaffected by gravity. But if gravity affects space and time, light is also affected, since the straight path that light would normally take would bend. This can be been seen when light from far away passes close to a massive object such as black hole.
Björn would like us to think of things like black holes, space-time curvature and gravity, and come up with a new poem that has at least some connection to the theme. I like the way the continuous form curves in a poem.
