从现在起50亿年，太阳会变得比现在大100倍，会吞没世界，那就是麻省理工或者其他所有的末日。

Five billion years from now, the sun will become a hundred times bigger than it is now, and it will just swallow up the world, and it will be the end of MIT, of everything.

维拉沃尔称，吞没金星以及跟地球间的潮汐作用将会把能量聚集在太阳的外层。

The swallowing of Venus and the tidal interactions with Earth will dump energy into the sun's outer layers, Villaver says.

因此，大约在50亿年之后，太阳将会吞没近围的行星——水星和金星。

As a result, some 5 billion years from now, the sun will engulf the inner planets, Mercury and Venus.
