Time dilation

Time dilation; the twin paradox.

There are two twin brothers. On their thirtieth birthday, one of the brothers goes on a space journey in a superfast rocket that travels at 99% of the speed of light. The space traveler stays on his journey for precisely one year, whereupon he returns to Earth on his 31st birthday. On Earth, however, seven years have elapsed, so his twin brother is 37 years old at the time of his arrival. This is due to the fact that time is stretched by factor 7 at approx. 99% of the speed of light, which means that in the space traveler's reference frame, one year is equivalent to seven years on earth. Yet, time appears to have passed normally to both brothers, i.e. both of them still need five minutes to shave each morning in their respective reference frame.

Org2 melayu, aku tak paham. Since aku sekolah (aku sekolah agama BTW), i was told that, kiamat dah nak dekat dah. Banyak2 kanla amal ibadat. Hmmm....dah nak dekat tu, bape dekat? Bkn itu yg nak aku persoalkan. Kiamat dah dekat atau kiamat lambat lagi, ibadat kpd tuhan tetap kene banyak. Tapi, duit tetap kene carik. "Ala, cari duit bebanyak watpe, bknnya boleh dibawak mati". Abih? carik duit sket je? Org2 kafir/Israel/Amerika, bejuta2 duit dia org dan tengok, apa dah jadi ngan org2 Islam yg "tak payahle dok cari duit bebanyak...". What if, it's the other way round? What if, yg banyak duit sebenonya org Islam? Aku salute ngan sorang org kaya nih, dia banyak duit, pastu dia bukak kelas blaja Quran FOC kat KL. Tengok, betapa duit yg banyak penting sebenarnya. Aku takkan lagi berfikiran sempit pasal duit. Akan akan cari duit banyak2, dan aku akan guna ke jln betul. Tamak haloba tu nafsu dan sifat seseorg manusia. Duit tidak mengubah perangai manusia. Tapi bila manusia tu tak beragama.....abisla sumernya...tiada berguna....

Hmmmm.....so....kiamat x lama lagi....from which reference time frame?
