And I think right now we’re in the stage where we don’t know whether things are going to go away when the data gets better or whether when the data gets better, we’re going to see a real sign that the model doesn’t work anymore.”The survey data from DESI may show that the current understanding of the universe is wrong — this would not be the first time this happened. At least we know that dark energy is not a particle-like dark matter. Some scientists think it could be another dimension leaking into our universe. But more than likely, it might be space itself. This would mean that space wasn’t actually empty, we just can’t see what it really is. But so what does “space itself mean?” We have no idea.
Given how new to the planet humans are on the grand scale, we’ve figured out quite a lot about the cosmos. We know the Earth is about 4 billion years old, we know that 13.8 billion years ago there was nothing and then there was everything. We know absolutely nothing about the first one ten-millionth of a trillionth of a trillion of a trillionth of a second but after that, we have the timeline worked out to minutes.
