Things don't always look as they seem. Some stars, for example, look like bright pinholes, but when you get them pegged under a microscope you find you're looking at a globular cluster—a million stars that, to us, presents as a single entity. On a less dramatic note there are triples, like Alpha Centauri, which up close turns out to be a double star and a red dwarf in close proximity. There's an indigenous tribe in Africa that tells of life coming from the second star in Alpha Centauri, the one no one can see without a high-powered observatory telescope. come to think of it, the Greeks, the Aboriginals, and the Plains Indians all lived continents apart and all, independently, looked at the same septuplet knot of the Pleiades and believed them to be seven young girls running away from something that threatened to hurt them. Make of it what you will.

It’s pretty hard to get to another star system. Alpha Centauri is four light years away, so if you go at 10 per cent of the speed of light, it’s going to take you 40 years, and that’s assuming you can instantly reach that speed, which isn’t going to be the case. You have to accelerate. You have to build up to 20 or 30 per cent and then slow down, assuming you want to stay at Alpha Centauri and not go zipping past. It’s just hard. With current life spans, you need generational ships. You need antimatter drives, because that’s the most mass-efficient. It’s doable, but it’s super slow.

Sayari yetu hujulikana kama Dunia na jua letu hujulikana kama Sol. Dunia imo ndani ya mfumo wa jua wa Sol. Mfumo wa jua wa Sol umo ndani ya mfumo wa jua wa Sol Sector au Solar Interstellar Neighborhood, kwenye wenzo wa Orion wa falaki ya Njiamaziwa, wenye mifumo ya jua zaidi ya 40 ikiwemo Alpha Centauri, Nemesis, Procyon na Sirius. Solar Interstellar Neighborhood imo ndani ya falaki ya Njiamaziwa yenye nyenzo nne zinazozunguka kwa pamoja na falaki nzima. Falaki ya Njiamaziwa imo ndani ya kishada (‘cluster’) chenye zaidi ya falaki 55 ikiwemo Andromeda, Leo A, M32 na Triangulum, kinachojulikanacho kama ‘the Local Galactic Group’. ‘The Local Galactic Group’ imo ndani ya mfumo wa kishada kikubwa zaidi kiitwacho Virgo Supercluster, chenye makundi zaidi ya 100 ya falaki. Virgo Supercluster imo ndani ya mfumo mwingine mkubwa zaidi wa vishada uitwao Laniakea (Local Supercluster) wenye vishada zaidi ya 500 vya falaki. Hapo ndipo mwisho wa ulimwengu wetu unaoweza kuonwa na wanasayansi wetu. Kutoka duniani mpaka Laniakea ni umbali wa kilometa bilioni trilioni 250, miaka bilioni 13.8 iliyopita.

Today, we commit to this next great leap into the cosmos because we're human, and our nature is to fly.
