- Galaxy filament (Wikipedia)
In cosmology, galaxy filaments are the largest known structures in the universe, consisting of ‘walls’ of gravitationally bound galactic superclusters. These massive, thread-like formations can reach 80 megaparsecs h−1 (or of the order of 160 to 260 million light-years) and form the boundaries between voids. Galaxy filaments form the cosmic web and define the overall structure of the observable universe.
- Fungiculture (Wikipedia)
Fungiculture is the cultivation of fungi such as mushrooms. Cultivating fungi can yield foods (which include mostly mushrooms), medicine, construction materials and other products. A mushroom farm is involved in the business of growing fungi.
