Death by Black Hole
Unfortunately, astronomers and physicists are pretty sure you can’t just go through a black hole and pop out the other side – you will, in fact, die. The real question is, how exactly will you die?

The Earth’s Gravity
Gravity on Earth acts on all objects with the same force. No matter their mass, objects fall and accelerate at a constant rate. Due to the air resistance of different shapes, this is not always apparent. On a planet or moon lacking oxygen, the law could be simpler to demonstrate. On Earth, falling objects…Read more The Earth’s Gravity

Zero Gravity
For most children, at some point in time, the only logical career path in the entire world is astronaut. They usually say it with reverence, for the word is akin to something half way in between magician and alien, full of all the magic and surprises that only someone who hurdles through the final frontier … More Zero Gravity

Nuclear Fusion: the Energy Source of the Future?
Though the power of the Sun is quite amazing, the Sun is simply a giant, burning ball of hydrogen. Due to the immense gravity of the Sun, hydrogen particles at the Sun’s core are under enough pressure that they collide with one another despite the force of the positive charges to repel one another. In […]

The Power of a Black Hole Merger
An article by Christopher Crockett in ScienceNews came out 5 days ago that stated the amount of power output by the merging of two black holes. This was the same event detected by the Laser Interferometer Gravitational-Wave Observatory, the first detection of observational gravitational waves. The power of merger was apparently 3.6 x 10^49 watts! […]

Negative Energy (Gravity)
When one considers that amount of energy that occurs from splitting a single atom, and then multiples that by the 10^80 particles that exist in our universe, one might conclude that the net total of energy in the universe is a astronomically large. Surely beyond anything a human mind could comprehend. The reality however is […]

How Gravity Affects Space-Time
One of the more interesting (and more confusing) concepts we’ve learned thus far in the Solar System is the bending of spacetime. As can be seen in the figure below, massive objects with gravity (such as planets or stars) have the unique property in that they can bend the spacetime “grid” around them. Before you […]
