In the films it's obvious that whatever the blasters and turbolasers are firing, they aren't lasers. The bolts travel way slower than the speed of light. So slow in fact that people with preternaturally high reflexes are able to block and dodge the shots.
This question Do (weaponized) lasers exist in the Star Wars universe?Do (weaponized) lasers exist in the Star Wars universe? mentions a number of these quandaries but doesn't actually answer them, instead wondering if actual lasers exist in the EU.
So what are they firing? And is there any in-universe reason as to why people don't use projectile firearms as a way of taking down these annoying Jedi who seem able to deflect all their blaster bolts?
I am aware that the out of universe reason is "because it looks cool". Which is fine. Just wondering if anyone's ever tried to explain this discrepancy in canon.
