With popular meteor showers diminishing in intensity: Are new sources created - and how often?
gpt
Meteor showers are caused by debris from comets as they pass near to the sun and break up due to tidal forces. The Earth passes through the debris clouds in its orbit, and the fragments burn up in the atmosphere. Comets are a lot more common than you may think, it’s just that most are too dim to notice.

Do you have a source that they’re diminishing in intensity? Are you sure that you’re just not noticing them as much?
