量化惯性的最小加速度
Minimum accelerations from quantised inertia
摘要：
最近观测到没有质量小于10^9太阳质量的盘星系，这个截止值还没有得到解释。这里表明，这个最小质量可以使用一个模型来预测，该模型假设1）惯性是由于Unruh辐射，2）这种辐射受到哈勃尺度的Casimir效应。该模型预测，随着物体加速度的减小，其惯性质量最终会更快地减小，从而将加速度稳定在最小值，这接近于观测到的宇宙加速度。当应用于旋转盘星系时，同样的模型预测它们有一个最小的旋转加速度，即：最小视质量为1.1x10^9 M_solar，接近观测到的最小质量。哈勃的质量也是可以预测的。有人建议，上述假设1可以使用回旋加速器来测试，以加速粒子，直到他们看到的Unruh辐射足够短，可以由人造辐射补充。惯性的增加是可以检测到的。
英文摘要：
It has recently been observed that there are no disc galaxies with masses less than 10^9 M_solar and this cutoff has not been explained. It is shown here that this minimum mass can be predicted using a model that assumes that 1) inertia is due to Unruh radiation, and 2) this radiation is subject to a Hubble-scale Casimir effect. The model predicts that as the acceleration of an object decreases, its inertial mass eventually decreases even faster stabilising the acceleration at a minimum value, which is close to the observed cosmic acceleration. When applied to rotating disc galaxies the same model predicts that they have a minimum rotational acceleration, ie: a minimum apparent mass of 1.1x10^9 M_solar, close to the observed minimum mass. The Hubble mass can also be predicted. It is suggested that assumption 1 above could be tested using a cyclotron to accelerate particles until the Unruh radiation they see is short enough to be supplemented by manmade radiation. The increase in inertia may be detectable.
