氚作为人择探针
Tritium as an Anthropic Probe
摘要：
我表明，如果氚只是20 keV轻相对于氦-3，那么当前的氘燃烧阶段的前主序星恒星演化将被取代的氘+氚燃烧。这个阶段会在相同的温度下发生，但会持续比氘燃烧最少4倍，最多8倍的时间，因此产生的总能量与太阳型前主序星的结合能相当。因此，它原则上可能会从根本上影响在同一时期形成的原行星盘。我认为，这可能是智慧生命所需的最“微调”的参数之一，质量范围只有中子-质子质量差的百分之几，以及它们质量的10^{-5}。我认为，这个范围的下限是由盘形成的物理学设定的，上限是由基础物理学的统计特性设定的。然而，如果后一种说法是正确的，那么物理“常数”的统计分布就必须是幂律分布，而不是指数分布。我还认为基础物理学和太阳系外生命/智慧的探索之间存在着深刻的联系。
英文摘要：
I show that if tritium were just 20 keV lighter relative to helium-3, then the current deuterium burning phase of pre-main-sequence stellar evolution would be replaced by deuterium+tritium burning. This phase would take place at the same temperature but would last a minimum of 4 times longer and a maximum of 8 times longer than deuterium burning and so would yield total energies comparable to the binding energy of solar-type pre-main-sequence stars. Hence, it could in principle radically affect the proto-planetary disk, which forms at the same epoch. I suggest that this may be one of the most "finely-tuned" parameters required for intelligent life, with the mass range only a few percent of the neutron-proton mass difference, and 10^{-5} of their masses. I suggest that the lower limit of this range is set by the physics of disk formation and the upper limit by the statistical properties of fundamental physics. However, if this latter suggestion is correct, the statistical distribution of physical "constants" must be a power-law rather than an exponential. I also suggest a deep connection between fundamental physics and the search for extrasolar life/intelligence.
