How does bluetooth work, essentially? I've never really thought about it up until now.

Bluetooth is a standard for connecting portable devices to wireless networks, and it's now almost as common as Wi-Fi.  It uses a range of radio frequencies to connect devices and is low power, allowing for extended battery life.  It's relatively secure, it's resistant to interference from other devices that use Bluetooth, and also from radio frequency interference.  And some new devices such as smartphones have been built from the ground up to support Bluetooth.

Can the bluetooth be hacked by outsiders?
user
Bluetooth's open protocol allows for a degree of security, however it's vulnerable to some of the same vulnerabilities as Wi-Fi.  In particular, attackers with access to a device's RF (radio frequency) address can listen in to the conversation and observe packets, though they can't do much more.  There is also the possibility of other network attacks like ARP and DNS cache poisoning.

How do I know if my bluetooth has been hacked?
