The Cosmic Spin-off That Created Our Solar System
Alright, let’s dive into how our solar system came to be, and trust me, it’s quite the cosmic tale. Picture this: over 4.5 billion years ago, the universe decides it’s time for a little creation project. So, in a neighborhood of our Milky Way galaxy, a giant cloud of gas and dust, known as a […] Continue reading
Nature’s Closely Guarded Secret – Nuclear Fusion
We are, quite literally, made of stardust. Stars are the birthplace of many of the elements that make up our physical reality as we know it. Heavier elements (heavier than Iron, specifically) were created in a Supernova — a violent explosion of epic proportions at the end of a massive stars life. Inside of every […] Continue reading
Blog 3: Climate Change Startups!
Climate change is one of the most pressing challenges facing humanity today. With each passing year, the evidence of its devastating impacts becomes more apparent, from extreme weather events to biodiversity loss. Addressing this crisis requires urgent efforts across various sectors. In recent years, startups have emerged, helping fight against climate change, leveraging innovation and […] Continue reading

Carbon Dating
Ever wonder how we know how old dinosaurs were? Or how long humans have been on the Earth? Well, it all comes down to a technique that scientists use called carbon dating. The process starts with the Sun’s radiation colliding with a N-14 causing a proton to fall off and creating C-14. This C-14 reacts […] Continue reading
What Americans Think of Space
The SpaceX Falcon 9 rocket carrying NASA’s Crew-5 Dragon spacecraft In 2023, the Pew Research Center surveyed over 10,000 American adults to understand Americans’ views of space issues. Here are a few of Pew’s findings : Pew also asked respondents how they would rate priorities for NASA’s space efforts. The survey listed the nine priorities […] Continue reading
NASA’s MAVEN mission
The MAVEN spacecraft NASA’s Mars Atmosphere and Volatile Evolution spacecraft (MAVEN) is studying Mars’s atmosphere. MAVEN was launched in November 2013 and arrived and arrived at Mars in September 2014. The MAVEN mission is helping scientists learn about how Mars loses its atmosphere and how/when the planet lost its water. MAVEN is an orbiter spacecraft […] Continue reading

The Universe’s Greatest Mystery That Threatens the Fabric of Physics
Wikipedia The foundational aspect of science is that a scientific theory that explains something about the natural world must be repeatedly tested and confirmed. If it cannot apply to every situation that meets the requisite parameters, then it is not a theory. Some information or calibration is missing, and the theory will be refined. Dark […] Continue reading

Gravitational Mysteries
by me The idea of gravity, the fundamental force that controls how objects move in the universe, is both intriguing and mysterious. Gravity is a force that pulls objects toward each other; it controls everything from an apple falling from a tree to a planet’s orbit around a star. It’s a force that operates over […] Continue reading
The New Wave
In a groundbreaking discovery, scientists have found evidence of ripples in the fabric of the universe, caused by the movement of colossal black holes. Albert Einstein once hypothesized this phenomenon – gravitational waves. Essentially, these are cosmic tremors that stretch and squeeze space itself. Imagine throwing a stone into a pond and watching the ripples […] Continue reading
Tides
Most people (including my past self) think that tides are only caused by the moon. While the moon does have a big impact on the tides. The sun also plays a big role in the way the tides move. The moon and the sun both have gravitational forces that pull on the Earth and cause […] Continue reading
