Is there a crisis in cosmology?

The standard model of cosmology is known as the LCDM model. While the observational evidence we have largely supports the LCDM model, there are some issues with it. One of the most bothersome is known as cosmic tension.

Is the Hubble constant wrong?

Researchers have found yet more evidence that our measure of the Hubble Constant, which represents the rate of expansion of the universe, is wrong. The new findings come after researchers used a set of radio telescopes to create new, precise measurements of the rate at which the universe is expanding.

How does astrophysics benefit society?

Technology transfer and spin-offs from astronomy have important applications in medicine, industry, defense, environmental monitoring, and consumer products. Mankind’s view of its place in the world as a whole is strongly influenced by the results of astronomical research.

What is the most violent event in the universe?

Thousands of times more energetic than ordinary exploding stars, their visible light as bright as a million galaxies, gamma-ray bursts are the most violent events in the universe, and radiation from one of these events reaches the vicinity of Earth at a rate of about one a day.

Does dark energy change over time?

Dark energy is thought to be different, though. As space expands, the dark energy density remains constant, rather than decreasing or increasing. As a result, after the Universe has expanded for long enough, dark energy comes to dominate the energy budget of the Universe.

Why Harry Potter should be taught in school?

Reading Harry Potter in schools gives children a chance to become turned on to the fun of reading a story, when they might not have that opportunity at home. Harry’s story is even more relevant to students from disadvantaged homes because the obstacles he faces are so like their own.

Why is astronomy not taught in school?

Astronomy in schools Astronomy is a specific branch of physics, so guiding students directly to astronomy could make more bad than good. There is the risk of learning the physics concepts superficially, which would be no good.

Why do we need astronomers?

By studying the cosmos beyond our own planet, we can understand where we came from, where we are going, and how physics works under conditions which are impossible to recreate on Earth. In astronomy, the Universe is our laboratory!
