點解d人要發明時光機?

有好多原因,就攞醫生來講,可以研究古代嘅失傳醫學,考古學家可以輕鬆知道古時嘅事,歷史書發行啇又可以出多幾本新書,揾多幾筆錢等等,甚至去未來做交流,開創人類史嘅新一頁都得,但係啲人應該唔會去破壞過去同未來的規律,或者番去過去阻止某人死,因為到咗嗰陣我估啲人都已經好有自覺性,知道如果亂來,最後可能會令歷史改變而搞到自己消失都唔定~如果我有部時光機,我想回到過去同細個嗰陣嘅自己玩同埋見吓我從未見過嘅爺爺嫲嫲

我會翻去過去，見多我公公幾眼，同埋同小學同學再Fd過○□○

Sorry, it is not true
Once the time machine is invented and used, the world will collaspe.
i.e. doomsday

First it is impossible to go back to past, for the time of the matters are different. There is no standardized and unified time for all matters. Also it is not possible to attain a speed of -c (speed of light)

Secondly, it is POSSIBLE to go to the future. But you may need to go through worm hole. Worm hole needs a huge amount of energy to stabilize. The energy, either used to stable or released by the stabilized wormhole, will cause the dark energy to proliferate. i.e. big freeze

番到以前
就可以回憶番以前D野

時光機用來穿梭時空
你係唔係睇得太多 多啦a夢
如果我你有部時光機
我會用來回到過去

回到過去.
是.
回到過去.爭取浪費的時間
