question is : Does antimatter fall in the same way matter does, or does it respond to gravity in a somewhat different fashion?After antimatter was discovered, Einstein pointed out that if the general theory of relativity was true, then antimatter would have to fall in the same way matter did.This, however, was just another one of Einstein's instincts, for there was no evidence either way. Nor ...
been reduced in numbers to a small herd in Perpetual danger of extinction. And, indeed, that extinction came, after a fashion, for in the 11960s the last Przewalski horse was seen in the wild.Yet the extinction was not entire and ultimate. A number of Przewalski horse had been captured and placed in zoos and they seemed to have no difficulty breeding in captivity. The result is that now, with ...
- astronomers expected to see a planet as quiet as Uranus. Instead, they found Neptune's atmosphere to be raging in fashion very much like that of Jupiter. It even had a "Great Dark Spot" very much like Jupiter's Great Red Spot. Where does Neptune get the energy for this? It's a problem that is fascinating astronomers.But what Wilbur and Montalvo noted on Sept. 24 wasn't on Neptune, either. ...
In the illustration, the dodo is pictured as an obese bird that we can easilly picture as waddling about in ungainly fashion. Its behavior would thus match its name and help explain why it is extinct.Kitchener does not think that is a true picture. It may have been based on some captive birds that were overfed and kept without the opportunity for activity. It may also have been influenced by ...
"mystery of the missing mass." In January, some astronomers reported that the missing mass may be made visible after a fashion.The missing mass belongs to objects in the Universe that can't be seen or otherwise detected but that astronomers are certain is there. They don't know what it is or what it might be but they are nevertheless certain it is there.How? Well, astronomers have studied a ...
itself by getting rid of the oxygen atoms. The carbon atoms are then put through their paces in a rather complicated fashion so that the different varieties can be separated. The carbon 14 is obtained and its quantity measured sured carefully by judging the rate at which it is breaking down and producing particles.The results in the case of the shroud were clear. The linen had been part of ...
the faster it was receding ― and at a rate proportional to its distance. This universal recession in just this fashion was most easily explained by the theory that the universe, as a whole, is expanding. If one imagined time reversing itself, then(as in a backward-running film)all the galaxies would seem to be approaching each other until, at some point, they would smash together into one ...
