Starship’s first integrated test in April 2023 was so powerful it tore apart the concrete beneath its launch pad and hurled debris hundreds of metres — by Flight 13 in July 2026, its upper stage was travelling more than 16,000 kilometres from Texas before touching down so gently in the Indian Ocean that it remained intact and afloat.
The universe is 13.8 billion years old, yet the observable universe is about 93 billion light-years across. That isn’t because light broke its own speed limit: while the oldest light travelled toward us, the space separating us from its source continued to expand, leaving that source’s present-day location roughly 46.5 billion light-years away.
In March 2025, DESI used nearly 15 million galaxies and quasars to build the largest 3D map of the universe yet. Combined with several other cosmic measurements, it strengthened a deeply unsettling possibility: dark energy—the force accelerating cosmic expansion—may be weakening, contradicting the standard model’s assumption that it never changes.
