John and Jack were both twins. Now Jack was on his voyage with NASA to look for life beyond our own solar system... so he was sent to Sirius XM, the closest Black Hole, to research gravitational anomalies in space...
WOW! This thing does have a kick. Going 80% of light speed or 2.4*10^8 m/s sure changes my ride, but helps e get there quicker.
After the long 4.2 light year journey, Jack began to orbit the black hole. He would then go on for 5 and a half more years to see the cosmos, along with conducting various experiments in his station to understand the gravity around a black hole.
And I am now 47. It was all relativity brother... Whilst you were flying in space near light speed, and going to the super massive black hole, time was experienced at different rate, hence why I am older than you now!
Houston, I will be leaving after living near this 50,000 Solar massive black hole for my five and a half years. Thank you for the assistance, but I will lose communication when I reach peak velocity. Jack finally prepped for the long trip back to earth.
Aaaaaah back home after that long bumpy ride home at 80% the speed of velocity. I can't wait to see John! I can't wait to see how my twin has done while transversed the cosmos. I am so glad I am done my 16 year trip.
I'm younger than you now??? But how??? I'm only 40.
So because I went really fast, my time experienced was changed by 17 years because of Special Relativity. Also, because we were so close to the large black hole, we experienced time slippage as well of about 6 years!
