On their 20th birthday, identical twin astronauts volunteer for an experiment. Terra will remain on Earth, while Stella will board a spaceship. Stella’s ship will travel to visit a star that is 10 light-years away, then return to Earth. As they prepare to part ways, the twins wonder what will happen when they’re reunited. Who will be older? Amber Stuver investigates the “Twin Paradox.”

I feel like this is the level of confusion that babies experience when looking at adults having a conversation
-
Imagine telling someone you're twins, and them saying, "oh, who's older," and you being like, "Terra, by 11 years."
-
Thank you. You saved my life. I had no means to cook food this morning but after watching this video I was able to cook my breakfast on the top of my head as this video set my brain on fire.
-
What I’ve learned: I’m as smart as a cat.
-
"Terra and Stella now both have a better understanding of how spacetime works" Me : Ok, but I don't
-
Imagine sending a message into space, waiting 2 years to only get a "👍" back
-
I love how they reunite and how surprised stella looks when an apple falls because it has been 11 years since she has experienced earth gravity
-
This video reminds me of when I came back to class after missing a few important days.
-
Imagine not having contact for a year only to receive a message saying “your fish died”
-
Imagine saying "Yeah she's my twin but she's 11 years older than me"
-
Special relativity is making a 6 minute video feel like an hour long
-
Oh I get it now. Terra -> means "earth" -> stays behind on earth. and "Stella" -> stellar -> stars -> goes to space That's all i understood though
-
If I ever have twin girls, I'm naming them terra and stella and telling them stella gets to be an astronaut but terra has fish to babysit
-
For everyone not getting it, we're the cat in the quote at the beginning of the video.
-
"We`re twins!" "Really? Who's the older twin?" Terra: "Me, by 11 years."
-
For people who do not understand, basically the twin paradox is where the saying that time goes slower in space is challenged, when in reality it goes extremely slow in the beggining and extremely fast at the end, equalling it out.
-
Doctor: you have six months to live Stella: lets make that a year
-
"Stella" means 'star' "Terra" means 'Earth'
-
One thing that's subtle and may further make difficult to understand is the following fact: Stella is moving at the speed of 86% of the light you have to keep remembering that so by the time the light signal from terra covers a light year, Stella would have further moved and the distance between the signal and her would be 72 % of a light year and so on so forth. Hence in about 7 years the first light signal reaches her.

Loved this! Thanks Amber for the amazing video
