Have you ever imagined what it would be like moving at the speed of light? To have the ability to travel that quickly (think ~300,000,000 m/s) would be incomprehensible — you’d experience a host of different effects, including time dilation (how more rapidly moving objects experience time more slowly), relativistic aberration (how your field of … Continue reading Traveling at the Speed of Light → Continue reading → Continue reading
The theory of special relativity tells us that there is an absolute speed limit in the universe, that being the speed of light. At a speed of about 300,000 km/s, light takes only one second to travel to the Moon from Earth and eight minutes to travel to the Sun from Earth. This speed is … Continue reading “Putting the speed of light into perspective” Continue reading → Continue reading
Traveling at the speed of light is entirely impossible in this present day and age, and the question of whether or not we will be able to travel at such a high speed or faster is still unanswerable. The speed of light sets the speed limit for the universe, so that should mean that light… Continue reading → Continue reading
Last winter break, I saw Interstellar. While various aspects of the movie interested me, the thing that especially stood out was the focus on time and the complexities it holds. Although Interstellar clearly wasn’t completely accurate in its science, it still brought up different aspects of space travel that are legitimate. In my opinion, the […] Continue reading → Continue reading
According to the Special Theory of Relativity, the speed at which light travels is the same in all reference frames. In other words, you will always observe that light will travel at 2.99*10^8 m/s, regardless of how fast you’re going. At first, one might think that this number is so high that it would make little […] Continue reading → Continue reading
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 → Continue reading
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 → Continue reading
Although the speed of light has been taught to be a constant value in a vacuum setting like the universe, however a team of Scottish scientists have valid proof that this might not always be the case. The Scottish researchers from the University of Glasgow and Heriot-Watt University made this amazing discovery by firing two […] Continue reading → Continue reading
In summer of 2013, the New York Times published an article about NASA’s (then) newest project. Physicists and engineers were trying to determine whether “warp drive” might one day be possible. Warp drive, for those of you who are not Trekkies, is traveling faster than the speed of light or 3.0 x 10^5 km/s, and thus far […] Continue reading → Continue reading
