How close are we to light-speed travel?

Best Answers

The problem is that as far as we know, faster-than-light travel is impossible, making galactic empires, federations, confederacies and any other cross-galaxy civilizations impossible. But that's so inconvenient. read more

So we are very far from travelling at anything close to the speed of light for the foreseeable future. Also, although it is theoretically possible to travel at speeds very close to the speed of light, we will never be able to actually reach the speed of light. Only massless particles travel at the speed of light. read more

Travelling at close to the speed of light may be necessary for humans to colonise the galaxy, but the maths show it'd be like flying through a cloud of bombs - but also that we should notice the explosions here on Earth, if any other civilisation has managed the feat. read more
