feel uneasy

 もやもや

ざわざわ

Something is wrong but I can’t tell the reason clearly.

12.9 billion years

 I always forget what billion means.

one billion is 10億　1,000,000,000

one million is 100万　1,000,000

100 million is 1億　100,000,000

129億年かかるという

その星からの光が地球に届くまで

They say it takes 12.9 billion years the light from the star reaches the earth.

What a distance 

Failure is a stepping stone to success.

Again and again 

I give up but I start from the beginning 

I will be a freshman forever
