1, the two-way foil in the three-body is a two-dimensional paper, which is a weapon to destroy the solar system.
2. Two-way foil is a dimensional attack weapon imagined by writer Liu in his work "Three-body III: Immortality" and a devastating attack weapon of interstellar civilization when the universe is in a dark forest state. A "small piece of paper" wrapped in a force field. At the moment of contact with the three-dimensional space, one dimension of the three-dimensional space curls to the micro, making the three-dimensional space and all the substances in it fall to the two dimensions, thus achieving the goal of destroying the enemy.
3. This object separated at a speed close to the speed of light can avoid damage, and its attack range is believed to eventually reach the space of galaxy level, or even larger. It is said that the two-dimensional space caused by two-way foil will expand infinitely around the action point.
4. In fact, in essence, the technology of water droplets is still the application of classical physics, but the classical physics is applied to the extreme. The two-way foil is a kind of dimensional change, which takes the universal law as a weapon to reduce the object from three-dimensional to two-dimensional. ?
This is the end of the introduction of the function of two-way film pasting.
