I don't know who that guy is, but I am just going to guess he is a 30-40 something atheist astro-physics degree holding professor or something. Just the vibe I get from the first 30 seconds of him talking.
Every generation has one of these guys, is not a half dozen of various popularity, and they all claim to understand the universe.
As they get older and people start pointing out the pinholes in their theories, they will switch gears to using open ended questions and shift their aura from certifiable expert to philosopher and theoretical physics.
Their perception is always flawed. It is always flawed because their starting point is that the human race is the most intelligent and advanced organism or entity even in the entire universe, even if they will state the possibility of otherwise. We can leave God out of this conversation, but it is important to note that as they do not believe in God, their perspective is that our lives are finite and there is nothing before or after. If they admit it or not, this does shape their perspective on the universe and their openness to admitting that the human race may be a bunch of chumps in the big picture and that our time here has a purpose besides breeding the next generation. They will always throw some half hearted "to our knowledge" or other similar sentiment to keep the faux scientist aura alive, but mostly they think they are the most intelligent person in the room at all times and if someone disagrees then they are not educated enough to understand.
That does not mean this person will never have a scientific break through or discovery, as we learn more and more about our own universe. But their perspective is always limited and opinions on where we as a species rank in the universe is always a combination of we are the best there ever was or will be and simultaneously none of it matters we are just monkeys that will breed more monkeys and then die and be gone forever. It is such a narrow and hypocritical view that I personally can't give their opinions any weight. They should stick to research. Their analytical minds may be good for seeking out facts through research but they are terrible at interpretting them because their view is so limited.
