求翻译：当它们之间接触的表面积达到某个临界值时，两个原子核就会融为一体，这个星体的体积就会趋向于零，引力变得无穷大，其结果就演化为黑洞；这种情况只有在大质量的恒星、也就是比太阳质量大1.4倍以上的恒星上才会发生；是什么意思？

When the contact area between them reaches a critical value, the two nuclei will be integrated, the size of the stars will tend to zero, gravity becomes infinite, the result is transformed into a black hole; this situation only in massive stars, which is 1.4 times larger than the solar mass star on

Contact between the surface area when they reach a certain threshold, when two nuclei into one, the stars will tend to zero in size, gravity becomes infinity, the result evolved into black hole; this situation only in the quality of stars than the sun, which is 1.4 times more than the quality of the

When between them contacts the surface area achieved when some marginal value, two atomic nuclei can merge into one organic whole, this photostar volume can tend to the zero, the attraction becomes the infinity, its result on the evolution is the black hole; This kind of situation only then in the b

When the surface area of contact between them when a threshold is reached, two atomic nuclei will be integrated, the volume of the star will tend to zero, gravity becomes infinite, the result into a black hole; this only in massive stars, which is 1.4 times larger than the Sun-times more stars will

When reaching a certain critical value in surface area contacted between them, two pieces of atomic nucleus will be combined together, the volume of this celestial body will tend to zero, the gravitation becomes infinitely great, its result is turned into the black hole; This kind of situation is on
