Is time travel possible?

by Wenbin Nah

Time Travel to the Past, Possibilities or Impossibility In our struggle to come to terms with our mental and physical reality, nothing vexes us more than the nature of time. For us mortals, time has been an enigma; a pu...read more

Time travel would be an amazing achievement for humanity and has been a fantasy for science fiction for a long time. Einstein's theory of relativity (1905) and experiments with atomic clocks has shown that forwards time tr...read more

Everybody travels in time. If you just do nothing for twenty-four hours, it will be tomorrow. You will have advanced in time by one day. Of course when we discuss time travel, it is either to travel backwards or to move...read more

Time travel, while not entirely impossible according to Albert Einstein's theory of relativity, is so fraught with paradoxes and uncertainties it will likely never happen. The concept is tantalizing for many in and out of ...read more

In Madeleine L'Engle's story, "A wrinkle in time", she uses the concept of a "tesseract" as travel through space and time. But what is a tesseract? You may have come across the term "tesseract" in your science-fiction r...read more

The second postulate of Einstein's Special Relativity Theory states that the speed of light stays the same for every observer regardless of RF's (reference frames). Now, this somewhat conflicts with the laws of RF's becaus...read more

Yes, because when traveling at speeds greater than 300,000km per second (186,000 miles per second) i.e. the speed of light, space and time are dynamic and distort so that the astronaut ages imperceptibly less than a person...read more

Time Travel ____________ Time travel is the concept of moving backwards or forwards to different points in time, in a manner analogous to moving through space. Additionally, some interpretations of time travel suggest ...read more

Jumping out of the space-time continuum forward or backwards is an intriguing concept at least since H.G. Wells wrote 'The TIme Machine'. Will space-time travel in that sense occur soon? The answer may be in the perceptio...read more

Einstein's theories of relativity suggest that time travel is possible. Einstein theorised that space and time are aspects of the same thing, space-time and these are not constant. As you travel close to, or even exceed, t...read more

Time travel as a described by pop culture movies such as "Back to the Future" and "The Time Machine" is impossible for a number of reasons. Most of these reasons while rather complex in theory can be explained in simplifi...read more

Time is an illusion. There is in fact no past or future; only present. What is referred to as "past" is in fact a present record of experiences that exists in the mind. What is called "future" is in fact a present percepti...read more

In short, from a scientific perspective, time travel is (and always will be) NOT possible. For a brief explanation, we consider the 'spacetime causality' as defined by the mathematician Hermann Minkowski. Essentially we...read more

Traveling through time according to the laws of physics as propounded by our foremost scientists is probably going to be a near impossible feat for any human being, as a result of the complexity of the variety of theories ...read more

If time travel is possible then our actions are predetermined. Let's start with time. Time moves in a solid direction at a constant pace. No object within time can move to next Tuesday any faster than any other obje...read more

Time travel is possible. The speed of light is as fast as is possible. If we figure out a way to go faster than the speed of light, we will either go back in time or forward in time. Of course we are always moving in t...read more

Science fiction has at times translated into science fact. Could this still be the case in our modern age? Could the vivid imaginations of sci-fi writers be somehow made into fact by our kind's most brilliant minds? One...read more
