Time travel has been the subject of many science-fiction books and films for the last few decades. But is it possible? Are there any time travel theories that could actually work? Understanding Time Travel We are all time travellers. That is to say, we all travel through time. We travel…
The deep space is filled with cosmic wonders, many of which can't be explained. The following deep space wonders defy common logic and inspire scientists as they peer into the fathomless universe. 1. Bizarre Mass of Objects Orbiting Star A strange pattern of light found orbiting star KIC 8462852 Discovered…
Dark matter is one of the unsolved mysteries in physics and astrophysics. This hidden matter, which is believed to form as much as 85% of the total matter in the universe, was first introduced about 60 years ago by the astronomer Fritz Zwicky. He developed and later proposed his “missing…
A long-time effort to detect gravitational radiation has finally led to a triumphant conclusion - for the first time after about a century of extensive effort, scientists have finally succeeded to verify and detect it. The discovery of gravitational waves was carried out with the participation of over 1000 physicists…
Since a century ago, new physics theories and ideas have led to many revolutionary results. Quantum mechanics and relativity theory and their profound concepts have not only changed our basic understanding of physics from the domain of elementary particles to that of the whole universe. Their weird interpretation of space, time,…
The issue of travel to the past has been a topic of great interest for the scientific community as well as the fans of science fiction, yet its feasibility has equally been a topic of intensively heated debates. Before the introduction of relativity theory (RT) and quantum mechanics (QM), our…
One of the most fantastic predictions of Einstein’s general theory of relativity has been the existence of gravitational radiation. Should gravitational waves be real, it means that the empty space as a medium for propagation of gravitational waves can itself oscillate and move. Since its prediction in 1917, a lot…
Black holes are regarded as the most extreme case of gravity. They are objects so compact with extremely high gravity that even light cannot escape. Their properties were first studied by the famous American physicists Robert Oppenheimer and Hartland Snyder in 1939 who theoretically proved that whenever a star of…
