如何计算Neutron Star Density
learn.whatIsHeading
Neutron star density is nuclear density (~10¹⁷ kg/m³) where electrons forced into protons: typical 1.4 M☉ in 10 km radius.
分步指南
- 1Input neutron star mass/radius
- 2Calculate density
- 3Compare to familiar materials and nuclear density
例题解析
输入
1.4 M☉, R = 10 km
结果
Density ~10¹⁷ kg/m³ (teaspoon weighs ~1 trillion kg)
Incomprehensible density
常见错误注意事项
- ✕Neglecting spin effects on structure
- ✕Assuming uniform density
常见问题
How is density even possible?
Neutron degeneracy pressure resists collapse; nuclear forces balance gravity.
