Orbital Decay and China’s Space Station
All satellites in low Earth orbit will eventual fall victim to orbital decay. Over time, a satellite will lose orbital energy through drag caused by friction with the atmosphere. Many large satellites, such as the ISS, employ small thrust to counter out the effects of orbital decay. However, as shown by China’s space station, … Continue reading Orbital Decay and China’s Space Station → Continue reading

~Gravitational Waves~
Gravitational waves!! Only recently detected even indirectly, they offer some evidence to support Einstein’s theory of relativity from the early twentieth century. The theory states that dense, heavy objects (like Earth, for example) distort space-time in the same way a marble would bend a normally flat stretch of fabric. When two extremely dense objects (such … Continue reading ~Gravitational Waves~ → Continue reading
Gravitational Waves and Extra Dimensions
The existence of dimensions beyond the three spatial and one temporal we experientially inhabit in our current model of spacetime has been a longstanding discussion touched on by various physicists and the scientific community. It has been suggested that gravity would propagate throughout these other dimensions, a thought brought about in attempts to somewhat unify … Continue reading Gravitational Waves and Extra Dimensions → Continue reading

Picture: Artist depiction of gravitational waves at work Gravity has long been one of the most transfixing ideas in our universe. For centuries, we have tried to crack the code of what exactly lies beneath our 9.8 meters per second squared. Since the apple first dropped on Newton’s head, we’ve been pining to understand … Continue reading gravity.wav → Continue reading
Gravitational Waves
Up until recently, the only way we have been able to gather information about stars, galaxies, and the universe around us has been through the study of light. However, as of the last few years, the discovery of gravitational waves provides a new method of collecting information about the universe. Although gravitational waves were first … Continue reading Gravitational Waves → Continue reading

Gravity
Gravity is a fascinating phenomenon of physics that is integral to understanding the universe. Gravity keeps Earth in orbit around the sun, and the Moon in orbit around Earth. Any object that has mass, also has gravity. Moreover, the gravitational force between two objects is caused by two factors: mass and distance. The gravitational force … Continue reading Gravity → Continue reading

Gravitational Lens by astronomical objects.
A gravitational lens is an observed image of light that is bent into a circle around the gravitational objects. The general relativity theory or the curvature of the space time is used to explain this amazing phenomena. When there is a sufficiently large gravitational objects such as stars, black holes and celestial bodies in the … Continue reading Gravitational Lens by astronomical objects. → Continue reading
