However, a minority of relativists continued  to contend that black holes were physical objects,<a href="http://en.wikipedia.org/wiki/Black_hole#cite_note-59" target="_blank">[60]</a>  and by the end of the 1960s, they had persuaded the majority of  researchers in the field that there is no obstacle to forming an event  horizon. Once an event horizon forms, <a href="http://en.wikipedia.org/wiki/Roger_Penrose" target="_blank">Roger Penrose</a> proved that a singularity will form somewhere inside it.<a href="http://en.wikipedia.org/wiki/Black_hole#cite_note-penrose1965-20" target="_blank">[21]</a> Shortly afterwards, <a href="http://en.wikipedia.org/wiki/Stephen_Hawking" target="_blank">Stephen Hawking</a> showed that many cosmological solutions describing the <a href="http://en.wikipedia.org/wiki/Big_Bang" target="_blank">Big Bang</a> have singularities without scalar fields or other exotic matter (see <a href="http://en.wikipedia.org/wiki/Penrose-Hawking_singularity_theorems" target="_blank">Penrose-Hawking singularity theorems</a>). The <a href="http://en.wikipedia.org/wiki/Kerr_solution" target="_blank">Kerr solution</a>, the <a href="http://en.wikipedia.org/wiki/No-hair_theorem" target="_blank">no-hair theorem</a> and the laws of <a href="http://en.wikipedia.org/wiki/Black_hole_thermodynamics" target="_blank">black hole thermodynamics</a>  showed that the physical properties of black holes were simple and  comprehensible, making them respectable subjects for research.<a href="http://en.wikipedia.org/wiki/Black_hole#cite_note-HawkingPenrose1970-60" target="_blank">[61]</a> The primary formation process for black holes is expected to be the <a href="http://en.wikipedia.org/wiki/Gravitational_collapse" target="_blank">gravitational collapse</a> of heavy objects such as stars, but there are also more exotic processes that can lead to the production of black holes.මේකෙ කියන්නෙත් මේක තාරකාවන් මගින් පමණක්ම සිද්ධ වෙන දෙයක් නෙමෙයි කියලා.If all nuclear burning in a star greater than about 1.4 <a href="http://imagine.gsfc.nasa.gov/docs/dict_qz.html#solar_mass" target="_blank">solar masses</a> were to stop, and the <a href="http://imagine.gsfc.nasa.gov/docs/dict_qz.html#star" target="_blank">star</a> allowed to cool and solidify, the solidified material would not be strong enough to support its own weight, and it would collapse as the <a href="http://imagine.gsfc.nasa.gov/docs/dict_ei.html#electron" target="_blank">electrons</a> were pushed into the protons to make neutrons.  This <a href="http://imagine.gsfc.nasa.gov/docs/dict_jp.html#neutron_star" target="_blank">neutron star</a> material is stronger, but the star would be only about 20 km in diameter. If you piled on more material, you would eventually get to the point where there is so much gravity that not even the neutrons could hold it up, and the star would collapse into a black hole. මේකෙත් කියන්නෙ න්‍යෂ්ටික පිපිරීමක් ගැන.තාරකාවක් මැරෙන්න කලින් ඒකෙ තුළ න්‍යෂ්ටික පිපිරිමක් සිදු වෙනවා.මේ Particle Accelerator එකෙන් ඒ තත්වයෙ පිපිරීමක් සිදු උනොත්[තාරකාවකගේ න්‍යෂ්ටික පිපිරීමකට සමාන] Black Hole එකක් ඇති වීමේ අවදානමක් තියෙනවා.මොකද මෙතන ඒ හා සමාන අභ්‍යන්තරික න්‍යෂ්ටික පිපුරුමක් සිද්ධ වෙන නිසා.<img src="/styles/default/xenforo/smilies/default/D.gif"  class="smilie" loading="lazy" alt=":D" title="Big grin    :D" data-shortname=":D" /><img src="/styles/default/xenforo/smilies/default/D.gif"  class="smilie" loading="lazy" alt=":D" title="Big grin    :D" data-shortname=":D" />මම දැම්මෙ මම හොයාගත්තු දෙයක් නෙමෙයි.වෙනත් Magazine එකක තිබ්බ Article එකක කරුණු යොදාගෙන.ඒවා 100%ක් හරි නොවෙන්න පුලුවන්.<img src="/styles/default/xenforo/smilies/default/D.gif"  class="smilie" loading="lazy" alt=":D" title="Big grin    :D" data-shortname=":D" /><img src="/styles/default/xenforo/smilies/default/D.gif"  class="smilie" loading="lazy" alt=":D" title="Big grin    :D" data-shortname=":D" /></blockquote>
