Nikola Tesla and the 3-phase AC electric motor, in his day), General Relativity still standing, in my model of the universe some still unidentified stimulus induces pulsing directional lines of gravity force to radiate from all objects in generally spherical fields of decreasing density and strength and, therefore, what is generally labeled as “time” is actually an incredibility rapid series of incredibly brief “now moments” interspaced with a probably equal number of incredibly brief “intervals.” When scientists demonstrate that time moving at high speed at a high altitude slows down, they are actually proving that clocks (even atomic ones) slow down when forced to move more rapidly through the “drag” of even fewer lines of still dense gravity force. Space just is and time just isn’t: based upon particular personal ‘insights’ in 2009 (e.g. We physicists strongly believe that going back to the past is simply impossible – but it’s nice to fantasize about it.”Ĭlick here to find out more about Koyama’s research: Challenging the general theory of relativity “Such matter would require properties that simply do not exist in nature. “I’m sorry to disappoint you but for time travel to be possible, we would need to discover a completely new type of matter that has the power to change the curvature of time and space,” Koyama says. As a professor of cosmology at the University of Portsmouth, he is best placed to tell us the truth. Could we ever go backward in time?įinally, the question of whether time travel could one day be possible had to be put before Koyama. So clocks aren’t telling us falsehoods: time indeed exists outside of our own perception. And a crucial ingredient in this is a consistent theory of time that explains how objects move. Understanding how these two effects work and influence each other is essential for ensuring that the global GPS network functions correctly. But because the satellites are traveling at very high speeds around the planet, this in effect helps to slow time down, compensating for the lack of gravity.” Therefore, time should actually go faster for them than it does for us on the ground, where we experience higher gravity. They’re placed at a very high altitude and thus the gravity they experience is weaker. “GPS works due to a network of satellites orbiting the Earth. “A good, solid example to get your head around all of this is to look at how we use GPS,” Koyama continues. Supported by the European Research Council, Koyama continues to investigate this theory. Physicists have even found that black holes warp the immediate space-time around them due to their immense gravitational fields. Many experiments have been undertaken that have since proven this to be true. Additionally, according to Einstein’s general theory of relativity, the gravity of a massive object can impact how quickly time passes. This works as outlined through Einstein’s special relativity, a theory of how speed impacts mass, time, and space. In short, the time you experience depends on your velocity through space as the observer. “We cannot disconnect the two, and the way that an object moves through space determines how it experiences time.” “When we speak of time, we need to think of space as well – they come in a package together,” Koyama says. Physicists though have discovered that time can actually behave differently and is not as consistent as Newton thought. ![]() ![]() We all experience time in the same way and we all synchronize our clocks in the same way, no matter where we are in the world, whether that be London, Tokyo, New York, or Buenos Aires. To this day, classic Newtonian thought on time – where time is constant throughout the universe – is still a good approximation of how humans experience time in their daily lives. “We use Newtonian physics to describe how things move, and time is an essential element of this.” Koyama is a Professor of Cosmology in the Institute of Cosmology and Gravitation at the University of Portsmouth. “In physics, we have what we call the idea of ‘absolute time’ and it’s used to describe different changes as a sequence of events,” Koyama begins.
