Propulsion Methods for Space Travel
One of the biggest problems that we have when it comes to interstellar travel is that we don’t have a spaceship that can go fast enough to get us where we want to go in a reasonable time. Luckily, we have some really smart scientists trying to come up with ways to make a really […]

Anti-Matter Propulsion
The use of anti-matter propulsion might be the key to interstellar travel. Anti-matter is basically normal matter that has opposite charges. When matter and anti-matter collide with one another, they annihilate one another and energy is released. Unlike with nuclear fusion, where only 3% of the total mass of the matter is converted into energy, […]

You Used to Call Me on Your Space Probe: Drake Equation
Personally, I love the Drake Equation. I think it’s extremely interesting to ponder, and it fascinates me that there are ways to roughly predict life within the Milky Way. However, I feel like the equation should be approached more so as a means to think about life rather than an actual mathematical equation. Rather than using […]

Contact: The Third Answer to Fermi’s Paradox
The Fermi paradox posits that there are only three possible answers to the question “Where is everybody?” in terms of the search for other intelligent life in the Universe. The three possibilities are as follows: We are alone Civilizations are common, but no one has colonized the galaxy There is a galactic civilization, but it …

The Need for Space Travel
“The future of humanity is going to bifurcate in two directions: Either it’s going to become multiplanetary, or it’s going to remain confined to one planet and eventually there’s going to be an extinction event.” – Elon Musk. In my last blog post, I talked about the possibility of another object in space colliding with […]

Asteroids: Death, or Life?
Just hitching a ride Most people don’t think of asteroids as the bringer of life to Earth. Actually, for many, it’s the exact opposite. When someone says asteroids many people automatically think about mass extinctions, specifically the extinction of the dinosaurs (which was caused by a large asteroid). However, there is a theory called panspermia which […]
