In the grand scheme of things:

• We're turbofucking the climate, even though we've understood the warming effects of CO₂ for 170 years, and had viable solutions to climate change for like 50. And yet we're increasing CO₂ emissions year after year. It's not certain the human civilization as it currently is will survive the next century.
• We're throwing non-biodegradable plastics everywhere, even though we've known for like 50 years that it is devastating for many ecosystems and human health.
• Capitalism is squeezing the global working class ever harder with each passing day, and yet class consciousness is not growing fast enough, despite us scientifically understanding the unsustainability and evils of capitalism for like 160 years.

So yeah, in that grand scheme of things, making models of the larger universe is not actually that important. First we need to make use of the discoveries made way over a century ago.
