This theory has far-reaching implications and has changed our perceptions of space and time. What Physicists discovered is that we are all continuously moving not just in three-dimensional space but in four-dimensional spacetime. In a similar way, all objects in the real world are moving in a four-dimensional spacetime, at a constant velocity as that of light. Sounds astounding but it’s true.
In about 100 years, theoretical physicist Michio Kaku believes we’ll explore the universe as pure consciousness — traveling at the speed of light, looking at asteroids, comets, meteors, and eventually the stars. “All of this within the laws of physics,” he says.
