Pundit,
You are talking of something very far away!
I think before they think ...on intergallactic adventures they hav to be very clear with ..closer enviroments...who knows may b the datas they are going to obtain...on the current ...mission might help...!!
Intergallactic siyo mchezo mwanangu,inabidi kwanza tucheze na hawa ancient five wonderers kwa sana tu.
The Milky Way, which is by no means a huge galaxy, is about
100, 000 light years across.That means if you are going at the speed of light (we are lucky to achieve 0.000001% of the speed of light c= 299,792,458 metres per second or 1,079,252,849 km/h) you will take
100,000 years just to go across our own Galaxy.
To go to the Andromeda galaxy (the largest galaxy in the local group) at the speed of light it is estimated to take
2.52±0.14 million years!, if you want to be more realistic and use 10% of c as the speed we can dream of reasonably attaining in the foreseeable future, that will mean the speed will be reduced by a tenfold, meaning the time will be increased by a tenfold from 2.52±0.14 million to 25.2±1.4 million years even though a more realistic figure by available or even foreeseable technology is more than five fold that much, meaning
252000 ±14000 million years,
about 20% of the age of the universe! . And this is just to go say hi to our neighbours, I am not even talking about going to inquire about the affairs of our "city" at the mayors office down yonder City Hall, a trip out of town would be stretching it and seeing an out of state cousin would be venturing outside space-time and into the multiverse, if not fiddling with quazars.
This is clearly science fiction territory for now, I mean even if we were to have the technology to attain 10% of c, what kind of propulsion/ energy would we use?
That is, unless you think of a clever solution to tunnel a shortcut in spacetime that will take you from one end of the universe to another such as suggested by manupulation of
wormholes and
black holes, highly speculative stuff in itself due to the unapproachability of these beasts.
