Why is the sky blue and sunsets colorful?

The color of the sky and the vibrant hues of sunsets are both due to the scattering of sunlight by the atmosphere, specifically a process called Rayleigh scattering. Why the Sky is Blue: While appearing white, sunlight is actually made up of many different colors, each with a different wavelength. As sunlight passes through Earth’s atmosphere, it interacts with molecules and small particles in the air. Rayleigh scattering affects shorter wavelengths (blue and violet light) than longer wavelengths (red and orange). Although violet light is scattered even more than blue,…

You must go to the loo and are naturally wide awake again afterward. The main reason is that our body slows down urine production at night so that we can sleep undisturbed for a few…

Cell phones and brain cancer – new WHO findings

Around 63 studies from 1994 to 2022 were evaluated by the World Health Organization (WHO), with a relieving result.The possibility that cell phones could cause cancer has long been a controversial issue. Cell phones—and wireless technologies in general – are an important part of our daily lives. Therefore, it has been crucial for the scientific community to address the safety of radiation exposure from these devices. Over the years, the scientific consensus has been confirmed that there is no link between the radio waves from cell phones and brain tumors…
