Zinthu Zomwe Zimakhudza Maonekedwe a Milalang'amba Milalang'amba ndi "mizinda" ikuluikulu m'chilengedwe chonse, yokhala ndi nyenyezi mabiliyoni mpaka mathiliyoni, mpweya, fumbi la pakati pa nyenyezi, ndi zinthu zakuda zosaoneka koma zamphamvu kudzera mu mphamvu yokoka. Ngati tiyang'ana zithunzi za milalang'amba, tidzaona kuti imabwera m'mitundu yosiyanasiyana: ina ndi yozungulira bwino (zozungulira), ina imawoneka yozungulira kapena yozungulira popanda kapangidwe kalikonse ka mkono...

Momwe Mungamvetsetsere Lingaliro la Mphamvu Yokoka mu Astronomy Mphamvu yokoka ndi imodzi mwa mfundo zofunika kwambiri mu astronomy—kwenikweni, ingatchedwe “chilankhulo” chomwe chimafotokoza chifukwa chake mapulaneti amazungulira nyenyezi, chifukwa chake nyenyezi zimapanga milalang'amba, ndi chifukwa chake kuwala kuchokera ku zinthu zakutali kumapindika. Ngakhale zingamveke zovuta, mphamvu yokoka imatha kumvedwa pang'onopang'ono: kuyambira ndi zomwe zimachitika tsiku ndi tsiku, kupita ku malamulo a Newton, kenako kupita ku ubale… Werengani zambiri
Malingaliro ndi Zitsanzo za Chilengedwe Chonse Chilengedwe ndi chiwerengero cha malo, nthawi, zinthu, ndi mphamvu monga momwe tikudziwira.
