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.

I am a professor of astronomy and physics at Yale University, where I teach an introductory class in cosmology. I see the deficiencies that first-year students show up with.

My students may have dexterity with the equations they're required to know, but they lack the capacity to apply their knowledge to real-life problems. This critical shortcoming appears in high school and possibly in elementary grades - long before college.

Growing up in Delhi, India, I did puzzles, explored numbers, and searched for patterns in everyday settings long before I ever saw an equation.

We knew from theoretical models that mergers of massive, gas-rich galaxies were more frequent in the past. Now we've found that these mergers are responsible for producing both the nearby obscured quasar population and their distant cousins.

We cannot explain the phenomenon of gravitational lensing without general relativity, and this is where MOND spectacularly fails.

If you know the shape of the lens and the image you get, you can work out the path that light followed between the object and your eye.

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.

We already have a pretty good knowledge of the universe's mass-energy content, so if we can get a handle on its geometry, then we will be able to work out exactly what the fate of the universe will be.

Evidence has been mounting for the key role that black holes play in the process of galaxy formation. But it now appears that they are likely the prima donnas of this space opera.

It is my idea that the public needs to be better educated about the nature of scientific inquiry and how the scientific process works. I firmly believe that this is the only effective way forward to combat the widespread distrust in facts and science.
