滑铁卢大学与周边研究所开展了有史以来规模最大的全球物理学家调查，结果揭示了学界在宇宙基本谜团上的惊人分歧1。调查由 Niayesh Afshordi 和 Phil Harper 主导，已发表在《物理杂志》上1。
在核心问题上，物理学家未能形成压倒性共识。仅有 68% 的受调查者同意大爆炸不一定代表时间的开始，51% 同意宇宙早期经历了急速膨胀1。关于标准宇宙学模型 ΛCDM，未能获得多数支持，这一结果可能与 DESI 最近的发现有关1。
在解释宇宙中的暗物质问题上，物理学家的观点更为分散：仅 17% 支持未发现的低质量粒子理论，12% 主张修改引力理论，21% 支持多种解释的组合1。对于量子引力理论，弦理论获得最多支持但仅占 19%，环路量子引力获得 12% 的支持，另有 18% 的物理学家认为引力可能无法被量子化1。
Afshordi 评价道："最显著的结果是，基础物理学中的很少'标准答案'能获得压倒性支持"1。研究团队认为这种分歧反映了物理学前沿仍然充满活力和未解之谜1。
A major global survey of physicists conducted by researchers at the University of Waterloo and surrounding institutes has unveiled striking discord within the scientific community over the cosmos's most fundamental mysteries.1 The findings demonstrate that core concepts in modern physics lack overwhelming consensus, with support scattered across competing theoretical frameworks.1
When asked about the Big Bang, only 68% of physicists agreed that it does not necessarily represent the beginning of time.1 On cosmic inflation—the theory that the early universe underwent rapid expansion—just 51% endorsed the idea.1 Regarding dark matter, responses were highly fragmented: only 17% supported the theory of yet-undiscovered low-mass particles, 12% favored modifications to gravitational theory, and 21% believed a combination of multiple explanations may be correct.1 Questions about quantum gravity produced similarly divided opinions, with string theory receiving the most support at 19%, loop quantum gravity at 12%, and 18% of physicists suggesting that gravity may not be quantizable at all.1
The standard cosmological model, known as ΛCDM, failed to secure majority backing among survey respondents, potentially reflecting recent findings from the DESI experiment.1 Lead researcher Niayesh Afshordi remarked that "the most striking result is that very few 'standard answers' in fundamental physics enjoy overwhelming support."1 The survey, led by Afshordi and Phil Harper, was published in the Journal of Physics.1
