Data suggest that central black holes might play an important role in adjusting how many stars form in the galaxies they inhabit. For one thing, the energy produced when matter falls into the black hole may heat up the surrounding gas at the center of the galaxy, thus preventing cooling and halting star formation.

The precise effects of lensing depend on the mass of the lens, the structure of space-time, and the relative distance between us, the lens, and the distant object behind it. It's like a magnifying glass, where the image you get depends on the shape of the lens and how far you hold it from the object you're looking at.

Evidence-based reasoning underpins all scientific thinking, and it involves testing hypotheses or theories against data. Validating a theory requires replicable measurements from independent groups with different equipment and methods of analysis. Convergence of evidence is critical to the acceptance of a scientific idea.
