What are the 2 things that keep something in orbit?
Could you explain to me, in simple terms, the two primary factors that maintain an object in its orbital path around a celestial body, such as a planet or a star? I'm curious to understand the fundamental mechanics at play here, and how these two elements work together to ensure the stability of an orbit.
Is orbit actually good for teeth?
Is it really beneficial for our teeth to be exposed to the unique environment of space, with its microgravity and radiation? Could the lack of gravity affect the way our saliva flows, potentially impacting our oral health? And what about the potential exposure to cosmic rays and other forms of radiation - could they have detrimental effects on our teeth and gums? It's a fascinating question, and one that deserves further scientific investigation to truly understand the potential impacts of space travel on our oral health.
