🚀 Artemis 2 isn’t just a test flight. It’s humanity’s return to deep space. For the first time since 1972, astronauts are leaving Earth orbit and heading for the Moon.

Time dilation means time literally runs at different speeds. ⏱️🌌 Einstein’s relativity shows that time slows down near massive objects and at high speeds. Astronauts, satellites, and people on Earth all age at slightly different rates, and GPS systems have to correct for it to work.

How do you relight a flame without a spark? 🔥🧪 @alexdainis.bsky.social breaks it down using the fire triangle: fuel, heat, and oxygen. When baking soda and vinegar react, they release carbon dioxide, a heavier gas that displaces oxygen and creates an environment where a flame can’t survive.

Fusion just crossed a line scientists once thought was impossible. By organizing plasma–wall interactions from the very start, researchers pushed superheated plasma beyond a long-standing density limit. This breakthrough reveals a revolutionary new way to overcome ... #RevolutionaryScience

What’s the biggest space mystery you want scientists to solve next? 🧪

NASA just put the Artemis II crew in quarantine, and that’s a big sign launch is near. 🚀🧪 Quarantine is a standard part of pre-launch prep, designed to keep astronauts healthy before heading to space, where even minor illnesses can pose real risks.

Even when electrons lose their particle-like behavior at extreme conditions, certain materials still display stable topological properties that show physics can still hold up without well-defined particles. #Electron #Particle #Physics #Science

Can too many vaccines overwhelm your immune system? 💉🧪 According to Dr. Ashish Jha, the science says no. Your immune system manages exposure to thousands of microbes every day, so handling more than one vaccine at a time is well within its capabilities.
