Sophie paused for a while to collect her thoughts and phrase them coherently.

"There are two big problems when it comes to the technique of hibernation. I'm sure you can figure them out by yourself.

The first problem is the question of how to preserve the human body in time. The second problem is that the longer the duration of preservation has to be, the more difficult the technique of hibernation is.

When the idea of hibernation first came about, the concept of freezing was agreed on almost immediately as the best method for preserving the human body in time.

But the problem was how long the duration could be. With our research. we've managed to increase that duration from one second to one minute, to one hour, and now half a day!"
