When seeking to test a hypothesis, it is helpful to start with clear and undeniable facts. But when the impact theory is applied to the prominent lunar “rayed crater”, Tycho, the theory fails even the most obvious tests.

Rays appear to radiate from some of the Lunar craters.

In this paper we evaluate quantitatively the hypothesis that topographic modification of floor-frac-tured craters on the moon was accomplished predominantly by viscous relaxation. Adopting the simple assumption that the moon may be modeled as having a uniform Newtonian viscosity, we compare the observed topographic profiles for a number of floor-fractured craters with the profiles predicted from the viscous relaxation of topography of fresh craters of similar diameter. Despite the simplicity of the rheo-logical model, the comparison is quite good. The floor uplift, the rim subsidence, and the apparent sub-sidence outside the rim for the several floor-fractured craters considered are well matched by the viscous relaxation hypothesis. Floor fractures, while indicating that a purely viscous model is not strictly valid, can be explained by the effects of isostatic adjustment on a thin brittle lithosphere. The association of many floor-fractured craters with impact basins and with the time of mare volcanism can be understood in terms of a pronounced acceleration of crater relaxation in local regions of anomalously high near-sur-face temperatures and therefore of low effective viscosity and thin lithosphere. The quantitative extent of relaxation of floor-fractured craters can be interpreted in terms of a limited time interval of substantial relaxation for each crater. That time interval ended for each crater after local cooling had been sufficient for the viscosity to rise, for the lithosphere to thicken, and for the present topographic relief to be 'frozen in. ' Thus viscous relaxation is a viable hypothesis to explain the topographic profiles of a number of lu-nar floor-fractured craters, and the extent of viscous relaxation of crater topography may serve as a tool to map lateral and temporal variations in the shallow thermal structure of the moon and of other planets and satellites.

It could be seen that no disturbances of the sort required by the impact hypothesis occurred in the event that gave birth to the crater.
Lunar craters are  on 's .The Moon's surface is saturated with craters, almost all of whichwere formed by impacts.

New Morphometric Data for Fresh Lunar Craters

This is a fundamentally important science problem. Although the impact cataclysm hypothesis and its effects are supported by existing data, the amount of data is still small. Thus, testing the hypothesis further is the nation’s highest science priority for lunar science (National Research Council, 2007). Additional analyses of Apollo samples and lunar meteorites are underway. Furthermore, exploration plans are being developed so that future astronauts can collect new samples on the surface of the Moon that will add depth to our understanding of impact bombardment and its effect on Earth history.

It is colder inside some craters near the lunar poles than it is on the surface of Pluto (25K, or -415F).

Though astronomers see Tycho’s rays as material ejected from the focal point of an impact, a mere glance at the picture above is sufficient to make clear that Is this surprising? A mechanical has a single focal point and these offset rays. Juergens noted that they "diverge from a common point, or common focus, located on or buried beneath the western rim of the crater." The electrical interpretation of Tycho sees the streamers as paths of electrons rushing across the lunar highlands to the highest point, where it launches into space to form the lightning "leader" stroke. The high point is destroyed in the process. The powerful lightning "return stroke" that forms the Tycho crater comes minutes afterwards and focuses on the nearest high point, a few kilometers to the east. In support of this explanation, the crater Tycho is surrounded by a dark halo of ejecta that blankets the extensive ray system, laid down earlier.
