Consequences of a Constant Speed of Light

I find it fascinating that what we see in the night sky is an image from the past.  Since nothing moves faster than the speed of light it is impossible to know what is going on at this exact moment on places other than the Earth and the Moon.  Hypothetically, the Sun could suddenly explode […] Continue reading

The Speed Limit of the Universe

58,536 km/h. That’s the speed of the fastest ever man-made vehicle: the New Horizons space probe. Though this may seem like an unfathomable feat to the layperson, there’s something that can travel even faster than that by five orders of magnitude. Light is the current “speed limit of the universe.” It travels at 3 x 108  m/s or 1 […] Continue reading

Common Misconception: The Earth’s Tilt At An Equinox

Upon visiting Dr. Grundstrom with a homework, I caught myself making a pretty silly error regarding the Earth’s Equinoxes. Looking at one of the homework questions for the seasons, I was asked to rank the order of several globes in order of how much daylight they received. One of the globes stood straight up, rotating […] Continue reading

The Cosmic Calendar

We, as humans, can have difficulty understanding amounts that exceed our narrow perspective. To aid us in understanding the 14 billion years that the universe has existed and the minuscule amount of time humans have inhabited it, scientists have put it in our terms of one year. Each month of the “cosmic calendar” represents roughly 1 … Continue reading “The Cosmic Calendar” Continue reading

The Great Shift

The Earth is like the top from Inception. As it spins around at very high speeds it wobbles or “precesses” back and forth as the force of gravity from the Moon and Sun tug it from different directions, but it will never fall over. This movement, although much slower and less noticeable than the Earth’s […] Continue reading

The Cosmic Calendar

The Cosmic Calendar is truly an eye-opening visualization of the entire age of our universe. It shrinks the entire 13.8 billion years that the universe has been around into one calendar year where each second equates to a few hundred years. The birth of the human species and just how little we have been around compared […] Continue reading

Bringing It All Together

Wow, it’s been a whole semester already. I’m about to be a senior and that is absolutely terrifying. I swear I was a freshman like two weeks ago. Of course, it’s all relative. If this time has been like a blink of an eye for me, it’s really some infinitesimally small fraction of the first […] Continue reading

Doctor Who is not COMPLETELY fictional

Image from wikipedia.com This article covers arguably one of my favorite topics to swoon over-Doctor Who.  I will be completely honest in saying that my intense interest in studying the solar system and beyond came pretty much single-handedly from watching Doctor Who (and maybe a teensy bit by my mom making me watch old Star […] Continue reading

Hello future me, I am the past you from the present (4th dimension)!

Is time travel possible? Would humans be able to discern how to accomplish it even if it was possible? Upon reading the 1884 novel, Flatland, an interesting notion is introduced to the audience. You can only completely see objects one spatial dimension below you, and can only infer the dimension you spatially occupy through the […] Continue reading

Gravitational Redshift

Most of us know about redshifting, a phenomenon of the Doppler effect. This is the change in frequency of a wave, both mechanical and electromagnetic, for an observer when there is relative motion between the source and the observer. For example, when an observer is moving closer to a wave source, each successive wave front […] Continue reading
