The cosmos doesn't work to my research schedule – but that's OK

I work on the dark matter problem knowing the questions I have may be answered long after I die. This is the life I signed up for: to think about interesting ideas and hopefully find out whether any of them are correct, says Chanda Prescod-Weinstein

Analysis

In November 2019, researchers were astonished when they viewed its image captured by the Hubble Space Telescope. Dark matter is an invisible substance that astronomers believe plays an important role in the formation of galaxies and is thought to comprise 85 percent of the universe?s mass. This discovery not only challenges the ideas of how galaxies form, but also provides evidence that dark matter is real. It shows that dark matter is not always coupled with regular matter in galaxies and that it has its own separate existence. In addition to lacking dark matter, galaxy NGC 1052-DF2 is an anomaly because you can see straight through it. This is called an ultra-diffuse galaxy because it has an extremely low density. As a result of these findings, a team of researchers are hunting for more dark-matter deficient galaxies to better understand the nature of dark matter and the formation of galaxies.

According to the consumer group Which?, 31% of electric car owners reported problems with their vehicle in the first four years compared with 19% with petrol cars, and 29% with diesel cars. The survey found that the most common faults with electric vehicles were software issues, not motor or battery problems.
