Fifth force

第五种力

现代物理学认为有四种基本作用力存在。然而,物理学中并没有一个公认的统一理论,因此偶尔物理学家们也会假定存在一个额外的基本力——第五种力。大多数物理学家假定第五种力大约和引力的强度相近(也就是说,比电磁力和核力弱得多),而其力程则从一毫米到宇观尺度不等。

Fifth force 第五种力

Modern physics describes physical reality in terms of four known fundamental forces. However, since physics has no accepted universal framework, occasionally physicists have postulated the existence of an additional fundamental fifth force. Most postulate a force of roughly the strength of gravity (i.e. it is much weaker than electromagnetism or the nuclear forces) and to have a range of anywhere from less than a millimeter to cosmological scales.
