Science Through Shadows: How Astronomical Alignments Reveal the Universe

When one celestial object passes in front of another, it can cast a shadow that travels across space – and sometimes across Earth. These moments of alignment, known as eclipses, occultations, and transits, allow scientists to study distant objects in remarkable ways. By observing how light changes when an object briefly blocks another, astronomers can measure sizes and shapes, detect atmospheres, and refine the orbits of asteroids and planets.

So, I'm in need of some confirmation of how UEFI works. Apparently, I don't even need a bootloader, because my UEFI shell already has that capability to switch boot entries? So then, I'd I just need to create an /EFI/BOOT directory in the EFI system partition, (from what I see it's often mounted to /boot or /boot/efi in Linux) and make a directory for each entry, containing an .EFI executable, a kernel image (vmlinuz) and the initramfs?

If I'm not wrong so far, great. Now, how do EFI stubs work? If it's the kernel booting itself from UEFI, do I not need an .EFI executable? Do I just dump a stub-compatible vmlinuz kernel image in /EFI/BOOT ?
