Large vortices formed in the oceans are mathematically equivalent to black holes, argue researchers in Switzerland and the USA. Hitherto unseen, these formations seem to transfer water over long distances and might affect the global climate.
The existence of these giant vortices, which can reach a diameter of 150 km, was known from previous observations. Their role in ocean circulation was difficult to study, as the limits of these rotating water formations were almost impossible to identify. Continue reading
The possibility of time travel has occupied both great scientific minds and sci-fi lovers for quite a long time now. Despite the fact that it is considered impossible by most physicists, there are still theories that could really work. Here are 5 most interesting ones:
1. Cosmic strings
Cosmic strings are hypothetical topological defects in the space-time fabric, still remaining from the formation of the universe. With their help, in theory, a field of closed timelike curves can be formed, allowing travel into the past. Some scientists suggest that cosmic strings can be used to construct a time machine. If two cosmic strings get close to each other or a single string reaches a black hole, Continue reading
Black holes are one of the most frightening phenomena that exist in space. Their gravitational force is so strong that they distort space and time beyond possible limits.
Therefore it begs a question what could happen if such a monster suddenly appeared or traveled to the vicinity of our solar system?
Before answering this question, let us first clarify some other questions. At what distance would it appear? Where would it come from? How massive would such a black hole be? Continue reading
According to a new theory of Stephen Hawking, black holes are probably not like he considered them to be in his previous theory 40 years ago.
Prominent physicist Stephen Hawking, one of the “fathers” of the modern theory of black holes, now comes to challenge some central aspects of his own theory, which are considered almost “doctrines” of contemporary physics. In essence, he claims that there are no black holes, at least as they are imagined by the scientists so far. Continue reading
Wormholes in space-time continuum, which are a great method of the rapid movements between different parts of the universe, are certainly well known to the readers of science fiction. Moreover, the concept of wormholes is well described in the space-time theory, where they are called Einstein-Rosen bridges and represent the deformation of space-time continuum. But apart from wormholes in nature, there is another related phenomenon called quantum entanglement, and a group of physicists from the University of Washington and the Stony Brook University in New York believes that these two phenomena are inextricably linked with each other. Continue reading
There are many points of view on the origin of the universe: from scientific theories and single hypotheses, to philosophical and religious assumptions. One of the most common is the so-called Big Bang theory, according to which, the universe originated more than 13 billion years ago and is constantly expanding.
Now, Japanese researchers presented evidence to suggest Continue reading
Considering the fact that humans will not be able to travel to the moon for the second time, without even mentioning other planets in the solar system, scientists are creating quite organized and compelling theories regarding composition and origin of our universe. These theories are based on long-term observations of visible parts of the universe as well as on guesses.
Ekpyrotic theory of how the universe has evolved
Everyone knows about the Big Bang theory. Without going into details about this theory, and remembering that now it is even taught in schools, let’s mention an alternative theory that attempts to explain the origin of our universe from a different perspective. Continue reading
Many theories about black holes that exist in space were developed over time. The prevailing opinion says that whatever falls into a black hole disappears forever and breaks apart into the component parts. However, a new theory states that black holes do not destroy the matter but rather are a kind of exit gates which lead in various parts of our universe or in other universes.
The new theory was developed by Jorge Pullin of the State University of Louisiana and Rodolfo Gambino of the University of the Republic of Uruguay. The two scientists decided to study the predictions of Continue reading
Outer space has always attracted and perplexed humans. Its mysteries fascinated, perturbed our imagination, and forced us to go deeper into the unknown. However, the more people studied space, the more mysteries they have come across. At the moment, scientists came up with seven major mysteries in space, the number of which can grow over the next decade or so.
Mystery #1: Is there life on planet Mars?
The so-called “Red planet” has long been a stumbling block for scientists. Not quite a black hole or the Andromeda nebula, located literally next door, it is causing so many questions… Continue reading
There are a lot of things we have learnt about the universe over the last millennium. But some things are still unknown to us, and these unsolved mysteries seem suspicious to us. Let’s take a quick look at some of the puzzling mysteries we have no knowledge about to this day.
1. What is the universe made of?
Just ninety years ago, we had no problem describing what the universe consisted of: atoms, which in turn consisted of (insert the words here you may have previously been taught about). But a lot of knowledge leads to a lot of disappointments, and according to recent views, the universe is 96% made of unknown Continue reading
