The Limitations of Light Speed

Posted on May 3, 2023 by jackdoyle25

As we all (hopefully) know, nothing can travel faster than the speed of light. Light-speed is the universal speed limit, and no matter or energy can move faster than it, including radio signals or other forms of communication. This limitation makes me rather pessimistic about deep-space exploration. The Milky Way Galaxy is massive, at tens […] Continue reading →

Gravitational Waves

Posted on March 17, 2020 by phildowd

Gravitational waves are a fascinating concept. The thought starts from the idea that gravity moves at the speed of light. Now, at the start this sounds like a silly idea. Doesn’t the force of gravity always act on people? Yet take this example. Say the sun were to simply disappear. Not explode or change, butContinue reading “Gravitational Waves” Continue reading →

Is it possible to travel faster than light?

Posted on January 20, 2020 by abbigailhughes

Einstein created a new physics framework with the notions of space and time, known as the theory of general relativity. As he continued to study these concepts, he realized the connectedness between the two, then referring to it as space-time. His theory explained how time does not go by at the same rate for stillContinue reading “Is it possible to travel faster than light?” Continue reading →

Kessel Run in Twelve Parsecs

Posted on January 23, 2018 by Nathan Xiao

The speed of light is one of the few constants in our universe that we consistently look to when it comes to space. It is an astronomical measurement that we only dream of achieving. Seeing the Millennium Falcon shift into overdrive or the Enterprise slip into hyperdrive are only distant fantasies for us Earth-bound creatures. … Continue reading Kessel Run in Twelve Parsecs → Continue reading →

LIGHTSPEED, COSMIC SPEEDLIMITS, AND (FINALLY!) LOOKING INTO THE PAST (Part 2)

Posted on February 15, 2016 by harperastronomyblog

In one of my previous posts , I explained what a light-year was and how the speed of light remains constant in a vacuum (a.k.a. space). I also explained that there would be another post explaining some of the things that I couldn’t fit in that post. Now I am finally ready to finish–the long awaited!–part […] Continue reading →

Lightspeed, Cosmic speedlimits, and Looking into the Past (Part 1)

Posted on January 26, 2016 by harperastronomyblog

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 →
