Exploring the Fascinating World of Quantum Gravity: A Discussion Among Readers

An ancient grave ⁢in southwestern England containing a sword, shield, and mirror is⁢ believed to have belonged ‌to a⁣ woman who ⁤fought in raids⁢ and defended against ⁢enemy attacks around 2,000 years ago. The discovery was reported⁢ by Bruce Bower in “Iron Age ⁢warrior grave belonged⁢ to a woman” ⁢(SN: 1/13/24, p. 5). Radar ‌data suggests that ‍enormous polygonal ‌rock patterns lie near⁢ Mars’​ equator deep‌ below the surface, indicating​ that the Red Planet’s equator was once much icier than⁢ it is now. Elise Cutts reported ‍this finding in “Buried polygons ‌hint at Mars’ tipsy past” (SN: 1/13/24, p. 12). Reader Robert‌ Walty questioned⁤ whether a cosmic collision could have caused the tilt of ⁤Mars’ axis to change, but​ geoscientist Ross Mitchell and colleagues believe that it was the natural evolution of⁣ the planet’s spin over ⁣time.⁤ For more information, visit www.sciencenews.org
