More energy is needed to rise a millimetre above a neutron…
““More energy is needed to rise a millimetre above a neutron star's surface than to break completely free of Earth's gravity. A pen dropped from a height of one metre would impact with the energy of a ton of TNT (although the intense gravity on a neutron star's surface would actually, of course, squash any such objects instantly). A projectile would need to attain half the speed of light to escape its gravity; conversely, anything that fell freely onto a neutron star from a great height would impact at more than half the speed of light.””
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
Extreme gravity of neutron stars makes small lifts require immense energy; escaping requires near‑light speeds, illustrating how gravity scales non‑linearly with mass and density.
In simple terms: Neutron star gravity is unbelievably strong.
