And new data are making the problem worse:
Something is wrong with the expansion of the universe. Nearby galaxies seem to be moving away from one another too fast, we don’t know why, and every new set of data just seems to make the problem worse.Leah Crane, “Something is seriously wrong with our understanding of the cosmos” at New Scientist
You have to pay to read the rest. The scene is ripe for the emergence of crackpot cosmologies like the multiverse, the computer sim universe, and why the space aliens are taking so long to land. Is that why we see so many of them?
Theoretical physicist Ethan Siegel says we’ll never know everything:
The total amount of information accessible to us in the Universe is finite, and hence, so is the amount of knowledge we can gain about it. There’s a limit to the amount of energy we can access, the particles we can observe and the measurements we can make. That doesn’t mean we’re done, or that we shouldn’t strive to learn everything we absolutely can. Only we can push the frontiers of knowledge back as far as they can go.
There’s a whole lot left to learn and a whole lot that science has yet to reveal. If we continue to look, many of the present unknowns will likely fall in the near future. But what is knowable is finite, and this implies that there are necessarily some things we may never know. The Universe may yet be infinite, but our knowledge of it never will be.Ethan Siegel, “This Is Why We Will Never Know Everything About Our Universe” at Forbes
So don’t fret that a better understanding of the universe will leave entertaining crackpots out in the cold. Won’t happen. Can’t.
