Une équipe d'astrophysiciens a mesuré la masse d'un trou noir supermassif grâce à l'effet de lentille gravitationnelle que sa galaxie provoque sur une galaxie d'arrière plan, très déformée... Ils trouvent une masse colossale de 32 milliards de masses solaires, ce qui fait de ce trou noir ce qu'on appelle un trou noir ultramassif. L'étude est publiée dans Monthly Notices of the Royal Astronomical Society.

in this episode, we explore how the weight lifting belt can enhance your performance, protect your spine, and help you lift more weight safely.

Join us as we explore the benefits of the and how it can boost your performance in the gym. From stabilizing your core to helping you lift heavier weights safely, this episode covers all the reasons why this tool should be in every serious lifter’s arsenal. Learn how to use the belt correctly, when to rely on it, and why it’s essential for anyone pushing their limits in the weight room. What Does the Weight Lifting Belt Do? First, let’s get into what the weight lifting belt is actually for. Contrary to what some believe, it’s not just for advanced lifters or competitive powerlifters. The belt’s main function is to stabilize your core and lower back during heavy lifts by increasing intra-abdominal pressure. This pressure acts as a brace around your spine, helping you keep proper form and protecting you from strain or injury.
