Aiden: I don’t want the sun to become a red giant (他最近在看天文方面的书,知道很多年后太阳会变大,吞噬周围的行星)……
mom: we can go to the other planets, which are far away from the sun.
Aiden: Saturn? It’s cold.
mom: maybe other planets in another solar system? Aiden, you don’t have to worry about this, the adults, the astronomers will plan this.
Aiden: Then, we need space suits.. will there be kids’ space suits?
mom: yes… at that time, you will have already grown up to be an adult.
Aiden: how about our house? will it be swallowed?
mom: well.. I don’t know. but we will have new house on the new planet.
Aiden: Can I bring DVD there? will there be food, library?
mom: Absolutely!
Aiden在沙发上沉思,然后说话了,带着哭腔:“what_if_I_am_sucked_into_the_black_hole?”
mom正在洗碗,赶紧过来坐在他旁边:”we are faraway from the blackhole, that is not going to happen.”
Aiden不理会:” I will miss my family..”
mom发挥自己的想象力:“the black hole is way big, if it is there, the whole house, the whole city will be sucked in ,maybe the whole united states.. so we will be still together.”
Aiden暂时不管黑洞了,又开始担心太阳的衰老:” when the sun is a red darf, it will swallow the earth.. we will be burnt..”
mom: no. what the book doesn’t tell you is that the sun will be smaller at that time, so it doesn’t have enough gravity to pull earth, so the earth will be far away from the sun, not going to be swallowed.
Aiden: no, a red giant means it is bigger, not smaller.
mom只好搬出了密度的概念:with the same size, a rock is heavier or a balloon?
Aiden: a rock.. en, the sun will be a red giant balloon, so it will be not heavy..earth will not orbit it and will go in a straight line, until it finds another sun.
mom正要让自己brain storm的大脑休息一下, Aiden又说话了: what if there is a black hole on the way? the earth will be sucked in..
mom: it doesn’t matter, it’s the entire each, u.s will be there, and china will be there. our house will be there too!
Aiden: there will be no light..
mom: light can be sucked in too.. remember that even the light is not able to escape from the black hole.. and we have flash lights!
Aiden: It will be cold, there is no sun there.
mom: our house is warm enough. when we want to go out, we will wear our winter suits, like what’s in the winter.
Aiden: will there be air?
mom: yes, air will be sucked in too!
Aiden想了一会儿,没有再问新问题,注意力明显转移了, 问妈妈上学的事情。妈妈暗自舒了一口气:我的宝宝,今天应该可以做个好梦了!
Aiden: en
