Pointless is a free collection of interactive cosmic calculators. The questions are stupid. The math is not.
We build tools that answer questions nobody asked, using real physics and real astronomical data. What would you weigh on Jupiter? How long does light take to reach Mars? How high could you jump on the Moon? If the Sun were a basketball, where would Earth be? How heavy is a teaspoon of neutron star material?
Every calculator on this site uses surface gravity data from NASA Planetary Fact Sheets, physical constants from CODATA 2018, and astronomical distances from IAU-approved measurements. The interface is fun. The numbers are accurate to the best of our knowledge. The science explanations are written in plain English — no degree required.
Pointless is an independent, one-person project built by a person who got tired of seeing the same boring calculators on the internet. It started as a single tool — "what would I weigh on Jupiter?" — and grew into a collection of useless but weirdly satisfying cosmic toys.
There is no company, no office, and no venture capital. Just someone who thinks the universe is cool and wants to share that feeling. If you enjoy it, tell one person. That's the whole growth strategy.
Because knowing your weight on a neutron star won't help you pay rent or get a promotion. But it might make you pause for 30 seconds and think about how weird the universe is. You're made of dead stars. You're moving at a million kilometers an hour and you can't feel it. The light you see at night left its source before humans existed. That's worth 30 seconds of your day.
All tools run entirely in your browser. No servers, no databases, no signups, no tracking of your inputs. The JavaScript on this page does the math locally. Your weight, your age, your sprint time — none of it is sent anywhere. We believe calculators should be free, fast, and invisible.
We do use Google Analytics to count anonymous page views (how many people visit, what pages they look at, what country they're in). This helps us know which tools are actually interesting. We do not track you across the web, sell your data, or share it with anyone.
Gravity data: NASA Planetary Fact Sheets (nssdc.gsfc.nasa.gov). Speed of light: 299,792,458 m/s (CODATA 2018). Astronomical unit: 149,597,870.7 km (IAU 2012). Neutron star parameters: Lattimer & Prakash (2016), Annual Review of Nuclear and Particle Science. Solar oscillation data: SOHO mission, NASA/ESA. All calculations use standard physics formulas for educational and entertainment purposes.
We add a new useless calculator every day. Recent additions include a cosmic noise player (synthesized deep-space audio), a solar system scale model you can arrange on your desk, and a collection of short cosmic stories. If you have an idea for a tool that doesn't need to exist, email us. We might build it.
