"I can remember when the first pulsars were discovered. I was able to go and sit down and listen to graduate students talking about what their theories, to explain what pulsars really were."

One of the hallmarks of Niven's novels is the use of realistic technology for space travel.
| Settling Home had been made easier by two techniques. The slowboats had carried sixty colonists each, in stasis. Sixty colonists would have filled three or four slow boats a century earlier. And, though no living thing could survive travel in a ramrobot, it had proved possible to ship fuel to the slowboats by ramrobots. An older technique was used extensively: colony supplies were shipped by ramrobot to orbit around Home, saving room aboard the slowboats. |

There is no way for a spacecraft to travel faster than light using currently available technology. However, interstellar colonization is possible using ships that travel at a substantial fraction of the speed of light.
Consumables are the biggest problem, given the length of time; also, journeys that take longer than a human lifetime are not easily undertaken.

'And he had been sent with troops, supplies and bombs to command Russia's most trusted post, the Moonbase.'
'What is your population', I asked. 'About eighty millions.'
'THE autobus turned silently down the wide street of Hydropole. Robot-guided, insulated from noise and cold...'
'The car had no steering wheel, and no one drove!'
Now that's power walking that Hugo Gernsback would have approved.
'It was disturbing to think of the Flatline as a construct...'

'On went the electric-yacht faster and still faster.'

'...he realized that it was not quite a clear lens. Speckles of colored brightness swirled and gathered in it.'
