Consider that nothing would be a temperature of absolute zero. Total equilibrium, where all the cosmic quantum fluctuations cancel out. Given there is no actual substance, even if they still think there might be strings, it's all a balancing act around nothing.
The great desire of our species is to be something. Rich, famous, athletic, influencer, stand out from the crowd. Yet definition is limitation. You are your definition.
Though if you practice your stillness, your nothingness, you can see much further than any definition can carry you. You can see through others definitions, like light shining through lenses. Or, more accurately, see their light trying to shine through all the filters they collect.
After awhile, it's all part of you and you are all part of everything else. Between nothing and everything. The absolute and the infinite. Fluctuations in the middle.
