Space
Stars, planets, orbits, and the physics that governs everything beyond our atmosphere.
What If the Moon Disappeared?
What would happen if the Moon suddenly disappeared? Explore the effects on tides, oceans, nights, wildlife, Earth's rotation and axial tilt, with established science separated from long-term uncertainty.
What If Earth Had Two Suns?
The outcome depends entirely on how the second star is arranged. A distant companion star would barely register day to day. A close one would produce extreme seasons, complex shadows, and possibly an unstable orbit altogether.
What If Earth Had Rings Like Saturn?
What would happen if Earth had rings like Saturn? Explore how an Earth ring system could affect the sky, climate, satellites, tides and human life.
What If Jupiter Became a Star?
What would happen if Jupiter became a star? Learn why Jupiter cannot ignite like the Sun and how a genuinely stellar Jupiter-mass transformation would affect the solar system.
What If the Moon Were Twice as Massive?
What would happen if the Moon were twice as massive? Explore tides, Earth's rotation, lunar orbit, coastal ecosystems and long-term changes to the Earth-Moon system.
What If the Sun Suddenly Disappeared?
What would happen if the Sun disappeared? Explore the first minutes, Earth’s orbit, cooling, oceans, atmosphere and long-term survival.
What If a Black Hole Appeared Near Earth?
What would happen if a black hole appeared near Earth? Explore tidal forces, orbital disruption, radiation and why distance and mass matter.
What If Earth Had Two Moons?
What would happen if Earth had two moons? Explore tides, eclipses, nights, orbital stability and the effect on life.
What If the Moon Had an Atmosphere?
What would happen if the Moon had a thick atmosphere? Explore weather, temperature, sound, erosion, life and lunar exploration.
What If Earth Moved 10% Closer to the Sun?
What would happen if Earth moved 10% closer to the Sun? Explore sunlight, temperature, seasons, oceans and orbital mechanics.
What If Saturn Lost Its Rings?
What would happen if Saturn lost its rings? Explore astronomy, moons, debris and what the Solar System would look like.
What If the Sun Suddenly Disappeared?
What if the Sun suddenly disappeared? Explore the delay in light and gravity, Earth's orbit, cooling, atmosphere and the survival of life.
What If a Black Hole Passed Near Earth?
What if a black hole passed near Earth? Explore gravitational tides, orbital disruption, radiation and what determines the danger.
What If Jupiter Disappeared?
What if Jupiter suddenly disappeared? Explore planetary orbits, asteroids, comets and the uncertain effects on Earth.
What If a Neutron Star Passed Near Earth?
What if a neutron star passed near Earth? Explore gravity, tides, radiation, orbital disruption and what makes neutron stars extreme.
What If Earth Lost the Moon and Sunlight at Once?
What if Earth lost both the Moon and sunlight? Explore tides, darkness, cooling, ecosystems and long-term planetary dynamics.
What If Earth Had a Ring System?
What if Earth had rings like Saturn? Explore how they could form, what they would look like and how they would affect Earth and satellites.
