From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

By intercepting the key on hardware level
Perfect security doesn't exist. If they've got the engineering capital required to design and manufacture key retrieval hardware, you lost the moment they gained physical access to your equipment.
Most brute-force attacks can be hardened against. Again there's no perfect security, just better security.
I agree. Physical access to the device and its often game over.
Sadly reading off the key is already trivial in some cases as showcased in this recent video by stacksmashing
Since the key has to be sent to the cpu in plain text it can easily be sniffed. If however the TPM is integrated in the cpu its not so easy, but then the os can be manipulated or hacked after boot with known exploits.
If you have a long and secure password for you encryption the absolute only way in is to brute force the key which is significantly harder if not impossible regardless of capital
Here is an alternative Piped link(s):

I'm open-source; check me out at GitHub.
If he uses TPM. I'm not aginst OP using it but he needs to understand the drawbacks. At least I hope he will.
