 有一次, (應該係初中)我在樓下踏單車
望上天空一看, 竟然給我發現一件不明飛行物體!
當時是二時至三時,天空是藍色的, 有幾厚的雲但是有足夠的陽光,雲層跟雲層中間是藍色(我想大家都知那是什麼天氣,其實都幾好天)
咁呢,隻野係發光既,係橙色的(所以咁清楚lor),形狀就我都唔記得,但係上面係圓.....
佢既速度比飛機快少許!我話比亞爸聽,佢叫我打電話去天文台check下當時有沒有什麼什麼在我家的上空飛過,我又唔夠擔打!

其實我很少便對天文產生興趣,剛剛take了一個天文的course,裡面提及有一位天文學家(Drake)在1961年創立了一條公式去計外星人(有智慧的)的比率,立即跟creato的朋友們分享下!(*是乘的意思)
N= R*fp*n*fl*fi*fc*L
N -- 可溝通的文族的數量
R -- 適合的星體的比率
fp -- 這些星體是星球的分數
n -- "地球"在每一個星系的數量
fl -- 這些星體上能發展生命的分數
fi -- 這些生命的地方(life site)裡有智慧的生物的分數
fc -- 有技術發展的星球的分數
L -- 這些可溝通文明的存在時間(life time)
我是英譯中,不足請見諒
