Like other electromagnetic particles, light has a specific velocity at which it travels. Further, it is presumed to be the fastest theoretical speed of any particle. The speed of light–referred to as “c” in a vacuum–is roughly 300,000,000 m/s. Since it moves so fast, most people never observe light as a moving particle or something […] Continue reading

Achieving Light Speed: Curvature Propulsion

Space curvature propulsion is a theoretical idea that has been explored through science fiction (including Cixin Liu’s Remembrance of Earth’s Past trilogy) as method of allowing ships to travel through space at or beyond the speed of light. While this idea currently resides firmly in the realm of science fiction, the theoretical basis is rooted […] Continue reading

The Limitations of Space Travel

Let’s just imagine for a moment that humanity eventually advances in technology such that light-speed travel is attainable. The speed of light, roughly 3×10^8 m/s, is the upper limit on travel speed- If light could go any faster, it would. With light-speed travel, humanity will likely attempt to colonize other planets, for a variety ofContinue reading “The Limitations of Space Travel” Continue reading

The Speed of Light: Can We Go Faster?

The speed of light in a vacuum is around 300,000,000 meters per second (for those more accustomed to freedom units, that’s 186,282 miles per second). Thanks to Albert Einstein and many other prominent scientists, we believe that only massless particles like photons are able to achieve this speed. This implies that it’s theoretically impossible forContinue reading “The Speed of Light: Can We Go Faster?” Continue reading

Limitations of Gravitational Slingshots in our Solar System

The use of gravity assist has been an integral part of space exploration. Gravitational slingshots have been used time and time again to send spacecraft to areas that would be impossible to get to otherwise by providing the spacecraft with increased speed. Accordingly, spacecrafts are able to get places faster and use less fuel. (Voyager […] Continue reading

Making the Jump to Light Speed

Chapter 1 of Astronomy: The Solar System served as a HUGE (seriously though) reminder as to how small and insignificant we are, and how very very very infinitesimally small the corner of the universe we’ve explored actually is. I’m a big Star Wars fan, and looking at that world from the perspective of astronomy class, […] 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

Is Light The Limit?

Albert Einstein once theorized that speed of light serves as somewhat of a global speed limit. It is assumed that nothing in the universe is capable of traveling faster than the speed of electromagnetic radiation. According to his observations, this makes sense. How could something composed of atoms of mass travel faster than a beam […] Continue reading
