Seriously ,again and again I find people asking about weather they can reach the speed of light , can't we think something bigger , something better . read more

That one is designed to reach 12% the speed of light, but is not doable today, and is not designed to take on humans, only automated probes. At this speed, reaching the closest stars beyond Sol would take decades, and we do not possess a life support system that would last that long and could fit into a reasonable volume. read more

As the speed of the object increases and starts to reach appreciable fractions of the speed of light (c), the portion of energy going into making the object more massive gets bigger and bigger. This explains why nothing can travel faster than light – at or near light speed, any extra energy you put into an object does not make it move faster but just increases its mass. read more
