Our Galaxy Could Be a Giant Wormhole, http://cialis24pharmacy-online.com/ Say Scientists

Could our galaxy be a huge wormhole like that seen in the movie Interstellar? And if that were true, would it be “stable and navigable?” Now a new study published in the journal Annals of Physics says yes.

“If we combine the map of the dark matter in the Milky Way with the most recent Big Bang model to explain the universe and we hypothesize the existence of space-time tunnels, what we get is that our galaxy could really contain one of these tunnels, and that the tunnel could even be the size of the galaxy itself,” says one of the study’s authors, astrophysicist Paolo Salucci, a dark matter expert with the International School for Advanced Studies (SISSA) of Trieste, Italy. “We could even travel through this tunnel, since, based on our calculations, it could be navigable.”

Although space-time tunnels (aka, wormholes or Einstein-Penrose bridges) have only recently gained much public interest in the wake of Christopher Nolan’s sci-fi film, they have been the focus of attention from astrophysicists for many years.

“Obviously we’re not claiming that our galaxy is definitely a wormhole, but simply that, according to theoretical models, this hypothesis is a possibility.”

To reach their conclusions the astrophysicists combined the equations of general relativity with an extremely detailed map of the distribution of dark matter in the Milky Way.

Scientists have tried to explain dark matter by hypothesizing a hypothetical particle, called the ‘neutralino.’ “But,” says Salucci, “alternative theories also exist, and perhaps it’s time for scientists to take this issue seriously.”

 

The Case for Returning to the Moon Grows Stronger

The case for resuming lunar exploration grows stronger by the day.

The tectonic forces of Earth may have destroyed records http://cialis24pharmacy-online.com/ of the very ancient past but that may not be the case on the Moon. Someday soon archaeologists will be able to search there for ancient extraterrestrial fossils encased in lava. Ancient lava flows, it is thought, could once have covered and sealed rocks and fossils arriving from space. But could any such materials survive exposure to super heated liquid rock? Recent tests at England’s University of Kent have demonstrated that organic materials on Earth could survive exposure to lava temperatures as high as 1300°F.

While the search for evidence of ancient life might be more than enough to motivate a new wave of lunar exploration, the mining possibilities are also getting some new attention. China with its Jade Rabbit mission has already made http://viagra24pharmacy-canada.com/ it clear it is after the moon’s rare earth minerals. (Perhaps they should be called ‘rare moons’) Some scientists believe that helium from the moon may one day power Earth. Recent discoveries of apparent water deposits have also shown it may soon be possible to obtain locally on our moon, oxygen for breathing, water for drinking, and fuel for rockets.

Could the moon soon become the last filling station for travelers venturing into the trackless wastelands of interplanetary space?
