Escape Velocity and Space Exploration
In our generation, space exploration has been an extremely valuable way to learn more about our solar system and our galaxy, the Milky Way. It is astounding that humans have been able to set foot on the moon, and that astronomical research centers have sent probes to a variety of astronomical objects within our galaxy, […] Continue reading

blog 2: Gravity over time
Isaac Newton originally conceptualized gravity as a mutually attractive force between all objects with mass. Those who came before him, such as Galileo, had performed experiments and attempted to establish increasingly robust understandings of this force, but none quite unified the idea like Newton. The story goes that Newton saw an apple fall from a […] Continue reading

Robert Navarro, Blog 01 Part 2!
Hello everyone, I will post a few fun facts about Physics (and Astrophysics) every Tuesday! Facts!! Image of the Day! 1/23/2024 Deep Nebulas: From Seagull to California Continue reading
Our Speed Limit
(its slower than you think) Many people know that the laws of physics dictate that nothing – and I mean nothing – can travel faster than the speed of light. It is not possible for any object, nor any information, to exceed 299,000,000 meters per second. At first, this seems to be an incredibly high […] Continue reading
The Speed of Light
In 1905, Albert Einstein took the first crack at the Newtonian foundational physics. In his paper on special relativity, Albert Einstein postulated that the speed of light, c, is constant in all inertial reference frames. Assume that a person on a bicycle is holding a flashlight and moving at a constant speed relative to someone […] Continue reading

And Then There Were Twelve?
In the ever-evolving world, the art of forging genuine connections remains timeless. Whether it’s with colleagues, clients, or partners, establishing a genuine rapport paves the way for collaborative success. Continue reading
The Limitations of Light Speed
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
Blog #8 – Black Holes and How to Find Them
Black Holes are quite a popular topic in astronomy, but I still would like to talk about them for my last post, since they are truly revolutionary. Black Holes, in short, are gravity’s ultimate victory over stars. After a star supernova explosion, the core of a star remains. But if this core weighs more than […] Continue reading
Variable Stars and change in the Night Sky
Image of Omicron Ceti (Mira) Source: Digitized Sky Survey 2 Looking up at the night sky it may seem that while the stars do move around, they remain the same brightness all year round. This was a common belief pushed by philosophers like Aristotle, believing that stars are eternal and invariable. However in 1638 Johannes […] Continue reading
Artemis
Since there has not been another moon landing. Until now. In 2024, Artemis 2 will launch and send the first person of color and the first woman to the moon. This mission’s goal is to establish the first long-term occupancy on the moon. This mission is the first step to then sending our astronauts to […] Continue reading
