Why immortality, not faster-than-light travel, may be the true price of becoming an interstellar species.

Imagine being offered a place aboard humanity's first interstellar spacecraft. Another sun awaits, but everyone you love may be gone before you reach it. Would you still go?

On a desert planet, no one survives a GoRak sting. She did. Hunted by terrified villagers, she crosses the desert and masters time itself—until she discovers what she was meant to become.

How can we deal with more dimensions than the three we can see? How does Maths help if our brains cannot bank anymore on experience?

It is a bold move to combine space and time to a bigger space - spacetime. Does this mean we can rotate space into time and vice versa? Read on for the surprising answer.

With the discovery of Exoplanets, listening to the night sky with radio telescopes should reveal a galaxy teaming of life. Explore with me one particular explanation for the Big Silence: civilisations are confined to their Bead of Time.

During all her childhood, TaaRell was different, but when she was becoming of age and sent into the desert, destiny was waiting for her.

Can we set foot on a planet in the Andromeda galaxy 2.6 million lightyears away? Can we get there in a couple of decades?

Faster than Light travel would upset the natural order of cause and action. This has consequences for who can roam between the stars.

Even if you add more and more energy to a space rocket, its speed increases but never surpasses the vacuum speed of light.

The twin paradox is explained by observing time slows in gravity. Sat Navs take this into account or, otherwise, would be inaccurate by about 10 km per day.

I review the evidence for the constancy of the speed of light. I bridge the time from the early days of the Michelson Morley experiment in 1887 - the most famous failed experiment in Physics - to modern times. We could have known earlier: Maxwell's theory predicted it in 1865. It needed the genius of an Albert Einstein to draw the conclusions.

The flow of time if personal, due to one observation only: light only travels with one speed.
