Using light as a barrier to block people without grilling them

2 $begingroup$ We know that light exerts pressure upon matter. I'm imagining a hallway where an intense light source on one end shines towards the other end. The goal is to have the beam of light exert so much pressure that a human being cannot enter (or reach the end of) the hallway. Of course, we only want to deter the human, not to burn them to a crisp. Would this be realistic? science-based reality-check light radiation share | improve this question edited 2 hours ago Cyn 5,866 9 35 asked 4 hours ago
