Speed of Light Slowing Down???
So we’ve all heard of Einstein’s theory of relativity which states that the speed of light is constant and all that good stuff. Well, apparently a couple of Australian scientists have found evidence that points to the possibility that the speed of light is not actually constant and has been slowing down since the Big […] Continue reading
Light Travel: The “New” Hyperspace
We’ve read it in our beloved science fiction books. Superheroes and intelligent beings from other worlds harness massive amounts of energy and cross through different dimensions – traveling faster than the speed of light. It’s the kind of thing space-obsessed kids (and adults, alike) dream about. We dedicate movies, like “2001: A Space Odyssey,” directed […] Continue reading

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

Lightspeed, Cosmic speedlimits, and Looking into the Past (Part 1)
In my last post, I made it a point to say that I would try to keep my blog interesting. In light of that decision (I didn’t even notice this pun until I already had this entire post typed up, so this one’s not on me), and because the winter makes me long for the […] 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
One Long Trip
When we look up at the sky during the night, it can feel comforting that instead of being surrounded by darkness, we see the bright twinkles of stars all around us. Though this might make us feel like we are not simply on a rocky planet hurtling through space far from everything else, this is not […] Continue reading

Blog #2 – Midnight Sun
Every morning the sun rises on the Eastern horizon, and every evening the sun sets in the West. I have seen approximately 7800 of these sunrises and sunsets over the course of my life. Every night I go to bed in the dark, … Continue reading → Continue reading

Consequences of breaking the speed limit
The effects of aberration and the Doppler Effect. Source: Comic Vine During one of the first class sessions, we were given a minute or so to write down what would happen if the speed of light was only 100 mph. I’d never really thought about this before, so I struggled to get anything more than “The… More Consequences of breaking the speed limit Continue reading
