Yes that makes sense but I think I still worded it wrong. The sensors and lasers would have clocks too but they wouldn't work by themselves, they would have to synced with the main clock. I'm quite possibly still wrong though and that is OK.
First off, I'm probably totally incorrect on all of this, so feel free to correct me.
Second, I'm only 15, so please just be gentle and helpful when I'm totally off.
Now for my idea:
Have a huge vacuum and put lasers on the inside with hundreds of different lasers at different angles equally...
