“During a trip to the beach yesterday practicing safe distancing observing both the gravitational pull of the sun and the moon as well as shadows and sun beams. I wrote science on the sand for added art!”
– love this image and the fantastically philosophical and scientific description! Although we can’t directly feel the gravitational pull of the sun and moon (since the pull of the Earth overwhelms them both), Kieran is right in that, at the seaside, we can see one dramatic effect of the moon’s gravity: tides! The gravitational pull of the sun is really most keenly “felt” (psychologically at least) over of a year; it’s what keeps us orbiting the sun over this time (and every year since and to come)!
