I mean I am brainlet here but almost every scientist I have spoken to says

1) All proposed methods for space travel are impossible and it's very unlikely we'll ever find a feasible method

2) Clean and free energy (any variant of fusion or solar) are also impossible

How do /sci/entists here cope knowing that whatever they accomplish will ultimately amount to nothing and it would've been better being a sport or other fun work chad having lots of sex?
