CAN MAN TRAVEL AT THE SPEED OF LIGHT? – 1

According to our laws of physics the answer is no. But the question for space travellers is how near the speed of light [c] we can get?

Light travels at 300,000 [approx] kilometres per second [186,000 miles per second]. When we look at our sun, not directly of course, we are seeing it as it was 8 minutes and 19 seconds ago. That is the time for light to travel 150 million kilometres [93 million miles]. 

Stars and galaxies are so far away that we express their distances in light years – the distance light travels in 1 year – 10 trillion kilometres [approx] – an unimaginable distance. 

Thus our nearest star is 4.2 light years away, our nearest galaxy 25,000 light years away and the Andromeda galaxy is a staggering 2.5 million light years away. 

For man only stars up to 10 light years away are potentially reachable. But to do this we need to travel at a significant fraction of the speed of light, say between 0.1 and 0.5c and this would equate to a journey time of 100 and 20 years respectively. 

In my view a journey time between 20 and 40 years is the optimum that human beings could tolerate – assuming we can crack hibernation [which I’ll talk about in a later Blog]. Therefore we would need to develop technology to propel a starship at between a quarter and half the speed of light. But can we do this? 

I will discuss the technology for achieving these speeds in my next Blog – but you might like to see how I achieve a journey to a star 10 light years away in The Blue People of Cloud Planet.

So the answer to my basic question is no, but a Dicepteron can!
