epq ideas?

i’ve chosen to do an epq for school, but i really have no idea what to do it on!! my a-levels are maths, chemistry, physics, i want to study engineering, and i have a real passion for space. i’m just struggling with a specific question to answer. literally any ideas would be appreciated, it doesn’t even have to be space related, just preferably linked somehow to my subjects. thank you!!

why not just go to university? space stuff is very specialised you will need aerospace engineering.
