When the Sun Dies

All good things must come to an end, including the ancient (at least relative to humanity), life-giving star we see each day. Even though the sun is considered a young star, it still has a finite lifetime, and it will eventually “die” in about 5 billion years. The image above shows a rough timeline of […] Continue reading

Warping the 4th Dimension

The concept of time dilation is one of the direct results of the theory of general relativity proposed by Albert Einstein, and it explains the effect of gravity on time. The theory of general relativity describes space as a three-dimensional space with time being the fourth dimension through which space is moving, creating the spacetime […] Continue reading

Blog 1: The Mystery of the Light-Year

People often confuse a light-year for a measure of time instead of a measure of distance. This is understandable since it has “year” in the name. A light-year is NOT a measure of time. The true definition of a light-year can be easily understood with a few simple facts and calculations. First, light travels at […] Continue reading

The speed of light and what it means for the Earth-Sun system.

The speed of light is one of the most important laws (or principles) in our Universe. The speed of light determines what we see and when we see it, as well as providing a universal “speed-limit” for countless celestial objects that zoom throughout the universe. I find it illuminating to consider the speed of light […] Continue reading

The Scale of the Universe (Post 1)

The universe is so massive that it can be difficult for humans to comprehend its scale, so I will break it down using something that we can easily understand. Earth is 1 AU (astronomical unit) from the sun or 150 million KM. If a human were travelling this distance in a car at 100 miles […] Continue reading

Solstices and Equinoxes The winter/summer solstices are, respectively, the shortest and longest periods of sunlight during the calendar year. The vernal/autumnal equinoxes are days in which the amount of time the day has with sunlight and without are of equal length. Days that are solstices/equinoxes demonstrate the formal change in seasons. This occurs because the […] Continue reading

The Fermi Paradox

Ever since humans have first become interested in space, the inevitable question of “does life exist outside of Earth” has loomed over us. However, as technology has progressed and humanity has trekked deep into space, the question remains unanswered. This brings about a certain paradox regarding the existence of alien life. The universe is almostContinue reading “The Fermi Paradox” Continue reading
