HOW MANY SPIDERS ARE IN MY HOUSE?
BBC Science Focus
|October 2025
Pest control companies will often give a figure of 40 spiders in an average house, but it's hard to find anything in the published literature that directly backs this up.
A 2016 study of 50 houses in North Carolina, US, found cobweb spiders in 65 per cent of all rooms sampled, but this was looking at biodiversity, and didn't count the number of individual spiders.

HOW DIFFICULT WOULD IT BE TO FLY THROUGH THE ASTEROID BELT?
In the 1980 film Star Wars: The Empire Strikes Back, Han Solo and friends try to escape pursuing imperial forces by flying through an asteroid field. Droid C-3PO remarks, \"the odds of successfully navigating an asteroid field is approximately 3,720 to 1\". The scene depicts a chaotic, dense field of rocks swirling and spinning through space. This scenario has been played out many times in the cinema.

HOW CAN I BE MORE PERSUASIVE?
Most of us like to think we're rational people. If someone shows us evidence that we're wrong, we'll change our minds, right? Well, not necessarily, because it's not always that simple. Being wrong feels uncomfortable and sometimes threatening. That's why changing someone's mind is often much harder than it seems.
