68% of physicists don’t think the time started at the big bang

A survey of more than 1,600 physicists found broad disagreement over whether the big bang began time and over major questions involving inflation, dark matter, and quantum gravity. Researchers say the divisions reveal where stronger evidence and new theories are still needed.

一项面向1600多名物理学家的调查发现，对于大爆炸是否是时间的起点，以及宇宙暴胀、暗物质和量子引力等重大问题，物理学界仍存在广泛分歧。研究人员表示，这些分歧揭示了哪些领域仍需要更有力的证据和新理论。
