2. Dark Flow: Something unseeable and far bigger than anything in the known universe is hauling a group of galaxies towards it at inexplicable speed.
3. Eocene Hothouse: Tens of millions of years ago, the average temperature at the poles was 15 or 20 °C. Now let’s talk about climate change.
4. Fly-by Anomalies: Space probes using Earth’s gravity to get a slingshot speed boost are moving faster than they should. Call in dark matter.
