nih paper bertarikh zaman dinosaur ka?

"The alchemists and the early nuclear scientists failed to realize that there's more than one way to skin a proton," Pidasso said. "Instead of trying to knock protons out of lead, protons can be borrowed from metals with lower atomic numbers and added to make gold."

lepas borrow dari metal lain, camana nak cantumkan dia? pakai gam? tak skolah punye saintis. bagus ko gi teman kambing mr os main nyorok2

Pidasso said the lab, a division of the U.S. Department of Energy, first achieved the transformation by borrowing protons from copper and nickel and adding them to bars of iron. But when copper and nickel supplies ran out, the lab began using protons from calcium, which is abundant in seashells along the nearby California coastline.

lab punye canggih, copper punye supply pun tak mampu nak beli. copper sekilo brape sen jek. esok lusa biar aku pos jek copper kat blakang rumah aku nih. kecik2 tuh pun ada gak berjuta2 proton yg ko nak tuh. dah kaye nanti jangan lupe kat aku pulak yek

kalo tak silap..unsur-unsur berat nie terhasil di teras matahari akibat tekanan tinggi,pastu akibat supernovae ia tersebar ke tempat lain..di matahari kalo tak silap emas yang jadik plumbum..terbalik aper yg alchemist cuba buat..alchemy kini dikenali sbg chemistry

sepanas2 bintang terpanas pun tak cukup untuk tukarkan elemen yg lebih besar dari Fe. apatah lagi unsur yg lebih besar dari itu. tunggu bintang2 besar meletup baru buleh dapat sket elemen2 tuh

Aku ade tgk NatGeo psl history of space....siri tu btau yg lpas bigbang...space ni hanya ade gumpalan hidrogen sahaja...then tarikan graviti yg menjadikan gumpalan ni seperti matahari...lepastu timbul la element seperti oksigen, carbon dan macam2 lg...

then aku teringt kisah ilmu kimia tercipta sbb org nk cipta emas...tp x berjaya...

topiknye ahli kimia dulu silap @ x psl penciptaan emas ni?...dr mane diorg tau? atau teori saje semata2...

diorang silap la tuh. mustahil buleh buat emas sebab perlukan temperature supernova. buleh ke buat lab cam gitu kat bumi?
