Physicists From Wales

"If dark matter is in the form of stellar mass compact objects, then the extremes of such variability are accessible to a monitoring campaign with the Hubble Space Telescope. With the advent of the Next Generation Space Telescope, cluster dark matter in the form of compact objects will induce a ubiquitous ‘shimmering’ of the giant arcs."

"If planetary systems are ubiquitous then a fraction of stars should possess a transiting planet when being microlensed. ... For the giant planets recently identified, the deviations in the light curve can be substantial, although the specifics of the perturbations are dependent upon the radius of the planet relative to that of the star, the location of the planet over the stellar surface and the orientation of the sweeping caustic. Given that the instantaneous probability of transiting hot-Jupiter like planets is small, less than a percent, and only a proportion of microlensing events exhibit caustic crossing events, the probability of detecting a transiting planet during a microlensing event is small, ~10-6. However, a number of factors influencing this probability, such as the number of solar type star that possess planets, are uncertain, and the prospect of detecting transiting planets in future large catalogues of microlensing light curves may be viable."

"What has led astronomers and cosmologists to come to this picture we have of this expanding universe that started in the big bang?"

"It's unnecessary to introduce magic into the explanation of physical and biological phenomena when in fact there is every likelihood that the continuation of research as it is now practiced will indeed fill all the gaps that Sheldrake draws attention to."

"This century has been so rich in discovery and so packed with technical innovation that it is tempting to believe that there can never be another like it. That conceit betrays the poverty of our collective imagination."

"John Maddox, the editor of Nature... retired in 1995. In August of that year, Maddox wrote an editorial entitled "Is the Principia Publishable Now?" in which he questioned whether or not Newton would get his ideas published today, given the current practice of peer review. Maddox speculates on what a reviewer would have written on receiving the script... He toys with the idea that Huygens (a contemporary... and opponent of Newton's ideas) would have written caustically about the gravitation ideas of Newton—"by what means, pray, does the author fancy that this magic can be contrived over the great distance between the Sun and Jupiter and without the lapse of time?""
