We often wish that we could go back in time and rectify our mistakes or go to the future and see what it turns out to be like. One thought is that time travel is certainly not possible, because if it would have been, then we would already have been visited by time travelers! However, let us not jump to conclusions and explore the question of whether time travel is possible, by going deeper into the subject.
Among all natural disasters, earthquakes stand out as the least predictable and the most destructive. The extensive damages they cause that have made them feared since antiquity. Since there are no scientifically proven means of predicting earthquakes (at least, not yet), the only lesson that we’ve learned from past quakes is that mitigation is more reliable than forecasting.
Titan — that smoggy, orangy moon circling Saturn — is of great interest to exobiologists because its chemistry could be good for life.
As far as stars go, ours is fairly ordinary and straightforward: a giant ball of absurdly hot gas that showed up a few billion years ago and has about a few billion left. But our sun is just one of at least 70 sextillion stars in the universe; with a number that huge, there are bound to be many far more interesting and bizarre than our own.
Space conspiracy theories make for great science fiction material. They have inspired a host of scripts in international cinema, novels, as also the formation of cults and communities of pseudoscience enthusiasts with ideologies based on supporting these theories. Without trying to prove or disprove them, let us dive into the paranoid and bizarre, but very intriguing realm of the most famous space conspiracy theories of all time.
White holes are the opposite of black holes, objects into which nothing can enter but are constantly spewing out matter. They were thought to be completely hypothetical, more a mathematical oddity than a real thing…but we may have seen one.
Moons in our solar system get little respect. The latest discoveries from planets like Mars and Saturn grab headlines. New comets invade the public consciousness. Meteors dazzle skygazers, and little Pluto attracts a fan club. Moons, in comparison, seem boring. The sheer number of these natural satellites in our solar system makes them overwhelming to study.
From 1968 to 1972, the United States sent a handful of men to the Moon. Twelve of them actually got to walk on it. Since then, nobody has been back. As the years passed, much of what those men did while they were up there has either been forgotten by an uninterested general public, or ignored by people who didn’t really care in the first place.
A group of astronomers and astrobiologists has revealed that alien life exists in our universe and the research teams are working hard to find them as early as possible.
If you believe what Hollywood tells us about alien life forms you’ll probably assume they’d be giant, slimy and really, really anti-human. As scientists don’t make a lot of movies, and movie producers aren’t typically awesome at science, this isn’t a very accurate portrayal of the interstellar life that’s at all likely to ever reach Earth.
Neutron stars are amongst the most extreme objects in the known universe. And I don’t mean extreme as in frontside 360 stalefish varial, I mean the kind of extreme that would’ve given Einstein bad dreams. Born in supernovae, neutron stars are the ultracompact insanely dense cores of once massive stars. And, it has to be said, these stellar corpses are rather odd. So, for your enterntainment, here’s 5 random facts about neutron stars and their general oddness!
Many of the oldest and most massive galaxies reside together in enormous structures known as clusters, and now a team of astronomers has confirmed the existence of an unusually distant galaxy cluster – a group of 19 galaxies located at precisely the same distance of 9.9 billion light years.
