Uncomfortable science means doing experiments or learning things that can make some people feel uneasy or uncomfortable. Like when you go to the doctor and you need to take some shots, it may not feel good, but it can help keep you healthy. Sometimes scientists have to test things on animals or people, and that can be uncomfortable too, but it can help find cures for diseases or new discoveries that could benefit us in the future. But scientists try their best to be kind and respectful to everyone and everything involved in their research, and they use very strict rules to make sure they don't harm anyone or anything. When we learn new things about the world, it may challenge what we already thought was true, and that can be uncomfortable too, but it's important to keep an open mind and be willing to learn and grow.
