In the grand scheme of things, we know so little of what there is to know. We could probably all venture guesses as to what could cause this apparent increase in how fast the matter thought to have originated in a big bang is moving away from us. Ultimately though, we can only know with confidence those things we can test for or directly observe.
Agree, we know so little.
But scientists need to open up about their actual risk of knowing the truth.
For instance, 4 months out, climate scientists cannot tell you reliably how many actual hurricanes will occur in the North American hurricane season.
In terms of astronomy, a 10th planet was discovered a decade ago. Why wasn’t it discovered before if astronomers are so smart? It takes the Sun’s light 6 hours to reach Pluto.
Meanwhile, astronomers speak nonchalantly about events happening hundreds of light years away. Betelgeuse is said to be 642 light years away.
Scientists will not tell us the truth about their science — because if they told the truth, they would no longer get funding.
