Open Question: Are Dark Matter and space curvature how scientists escape from geocentrism?
Hubble:
“the unwelcome position of a favored location (i.e., geocentrism) must be avoided at all costs…such a favored position is intolerable…Therefore, in order to restore homogeneity and to escape the horror of a unique position…it must be compensated by spatial curvature. There seems to be no other escape” (The Observational Approach to Cosmology, pp. 58-59).

Have these theories arisen due to actual observations, or from philosophical biases and salvaging favorite scientific models?

Open Question: Why do scientists find old human-like skulls and assume we used to be apes? What proof is there that we've cha?
There are many facts that point that we evolved from a primate that isn't around anymore. There are many details of a humanoid skull that are different from a gorilla, as you say.
There is also this newfangled discovery called DNA. They can compare the DNA from the skulls they have found with human DNA from now. We share 98% of our DNA with chimps, but we didn't evolve from them. We share a common ancestor from way, way back, and somewhere along the line our genetic lines split and one branch evolved into us and another evolved into chimps.
The skulls they have found, along with other skeletons are from that common ancestor before the branch separated.

Open Question: Scientists can determine the age of ancient objects by a method called radiocarbon dating.?
Home >All Categories > Science & Mathematics >Mathematics >Open Question
bookie Member since:August 15, 2006Total points:103 (Level 1)Scientists can determine the age of ancient objects by a method called radiocarbon dating. The bombardment of the upper atmosphere by cosmic rays converts nitrogen to a radioactive isotope of carbon, 14C, with a half-life of about 5730 years. Vegetation absorbs carbon dioxide through the atmosphere and animal life assimilates 14C through food chains. When a plant or animal dies, it stops replacing its carbon and the amount of 14C begins to decrease through radioactive decay. Therefore, the level of radioactivity must also decay exponentially. A parchment fragment was discovered that had about 64% as much 14C radioactivity as does plant material on Earth today. Estimate the age of the parchment.Answer QuestionBe the first to answer this question.
