Everything is energy. Balance must be made or else cancerous forms will occur. Advanced particle physics comprehension would be required at this level in order to deal with cancerous energy in the body.
Firewall at the edge of solar system moves along in it’s sine wave motion as the rest of the system. There are always three layers to everything before adding the firewall due to injury.
Solar systems have their own “laws of physics” according to each system. You can consider that as CF of the system. Going from our system to the next, will require obeying the new rules of that system. Advanced knowledge is required before going to a new system. You don’t want to end up with a day old life span in the new system, now do we?
