In the grand puzzle of the cosmos, one question continues to defy easy answers: how fast is the universe expanding?

A peer-reviewed study confirms the mathematical feasibility of time travel using closed time-like curves (CTCs), as posited by Einstein. Tobar compares the outcomes to the monkey’s paw—actions ...

With the unit of light-years, we can begin to make sense of the very great distances between objects in the universe and begin our time travel exploration. 1. Using the chart below, calculate the ...
