Question for all

Hi guys, I have no idea if this is the right subreddit but I’d love to know others opinions on this topic. I’m studying a masters in astrobiology in London. I’m in my 2nd year as I’m doing it part time, and I’ve come to realise that the more I study space and the more I look at things on a universal scale the more I realise nothing truly matters. I know that the idea that nothing matters is a more nihilistic approach (hence why I’m writing on this subreddit). But I was curious whether any of you have picked up a more nihilistic mindset due to our size in comparison with the rest of the universe? Thanks :)
