sorry for subject title. bukan apa, dah lama tringin nak wat, baru ade peluang

nursyah, sy bukanlah pakar sgt pasal black hole ni, tp sy cuba jelaskan apakah itu black hole berdasarkan apa yg saya tau...

seperti mana yg tertulis dalam buku teks sains di sekolah rendah ataupun menengah, black hole merupakan peringkat terakhir dalam evolusi bintang yg 10 - 15 kali lebih besar drp matahari.

BH (black hole) dipanggil sedemikian kerana gravitinya yg terlampau kuat, hinggakan cahaya pun x dpt melepaskan diri drp BH. oleh sebab tiada benda yg lebih laju drp cahaya, so there no things that can escape from the BH gravitational field.

but, why the BH's gravitational field is extremely strong?
gravity is an bizarre force. according to my understanding about it, everythings that have mass, will has gravity. Bigger the mass, stronger the gravitational field. ( if i wrong about it, please correct me immediately. if u ask why instead, i will asking the same question to someone else coz i'm not quite understand about it yet) If we compare a BH and a star, we will see that BH is so small than the massive star. Being small doesn't mean that it has less mass. actually, BH is a massive star with a massive mass that become smaller in size. so, BH is a dense small star.

p/s: sebenarnya, sy xtau nak britau apa pasal ni. it is better for u to   ask a question about it. baru tau nak inform apa, tau apa yg sy masih tau pasal BH ni. .

satu lg, maaf kalau ayat berbelit-belit. en. shah dan ahli2 tolong betulkan kalau ni ajaran sesat...
