摘要：

我们提出了一个新的经典引力理论，它是基于等效原理和假设的重力，类似电动力学，是由闵可夫斯基时空中的矢量场描述。我们表明，这样的假设产生一个独特的引力理论，它通过了所有可用的测试和自由的奇点，如黑洞。在目前的理论中，重力由四个方程描述，例如，任意静态场的精确解析解对于宇宙学，我们的方程给出的宇宙演化基本上与广义相对论相同。我们的理论预测可以在未来几年内进行测试，更准确地测量在太阳附近传播的雷达信号的时间延迟，或者通过VLBA解决我们银河系中心的超大质量物体。如果广义相对论是正确的，我们一定会在银河系中心看到一个黑洞的稳定阴影。如果目前的理论是正确的，那么阴影可能会周期性地出现和消失，周期约为20分钟，正如我们在JCAP 10（2007）018中预测的那样。对这种振荡的观测也将为质量在meV范围内的暗物质轴子提供证据。

英文摘要：

We propose a new classical theory of gravity which is based on the principle of equivalence and assumption that gravity, similarly to electrodynamics, is described by a vector field in Minkowski space-time. We show that such assumptions yield a unique theory of gravity; it passes all available tests and free of singularities such as black holes. In the present theory, gravity is described by four equations which have, e.g., exact analytical solution for arbitrary static field. For cosmology our equations give essentially the same evolution of the Universe as general relativity. Predictions of our theory can be tested within next few years making more accurate measurement of the time delay of radar signal traveling near the Sun or by resolving the supermassive object at the center of our Galaxy with VLBA. If general relativity is correct we must see a steady shadow from a black hole at the Galactic center. If the present theory is right then likely the shadow will appear and disappear periodically with a period of about 20 min as we predicted in JCAP 10 (2007) 018. Observation of such oscillations will also provide evidence for dark matter axion with mass in meV range.
