Gravitational lasers: Theory where space ripples, influenced by theoretical dark matter particles (axions), might make black holes emit laser-like beams.


  1. Space lasers theory is linked to Einstein's ideas.
  2. Axions, essential for the laser effect, circle black holes.
  3. Future tech, Laser Interferometer Space Antenna (LISA), might detect these beams.
  4. Combines major physics theories, enhancing understanding of the cosmos.
