Space is filled with an unimaginably large number of things; things that benefit us, like sunshine from the sun, and gravity, which keeps us in orbit and basically prevents us from flying into the abyss.But there are plenty more things that have been found in space that are very dangerous...
These quantities also encode the total energy, momentum and angular momentum dissipated via gravitational radiation (Bremsstrahlung). A special feature of gravity is that the field hµν does not relax to zero after the scattering event; instead, it takes on a new finite value — the memory ...

It is now believed that galaxies that don’t feature active nuclei, despite having supermassive black holes, are most likely to have run out of matter to feed the black hole and generate radiation. 12. Space Cannibalism A composite image of galaxy NGC 3393 | Image Courtesy: X-ray: NASA/CX...
