Similar time frame to the CWGC
A million to one, they said.
I've said this before, but I really think we should keep our heads down!
If there are super-advanced-creatures out there in space, they would surely look on us as rather slow moving cattle, and use us as a way of restocking their freezers.
So my advice is to keep quiet and put that bloody light out!
Remember what happened in A for Andromeda when the aliens got in touch by radio?
To late as per my other thread we have even given them a map to find us
Voyager 1 and 2 Space Craft journey timeline
This bit is hilarious...
''In fact, the core of M13, to which the message was aimed, will no longer be in that location when the message arrives''
See they thought of that apparently when found the co ords will be a locomotive town somewhere in Wilts so the rest of us are ok
You do see people wondering "why is it so quiet out there" - Fermi paradox - Wikipedia
Drake equation - Wikipedia
N = 1.5 × 10−5 × 10−9 × 0.2 × 304 = 9.1 × 10−11
i.e., suggesting that we are probably alone in this galaxy, and possibly in the observable universe.
On the other hand, with larger values for each of the parameters above, values of N can be derived that are greater than 1. The following higher values that have been proposed for each of the parameters:
R∗ = 1.5–3 yr−1, fp = 1, ne = 0.2, fl = 0.13, fi = 1, fc = 0.2[Drake, above], and L = 109 years
Use of these parameters gives:
N = 3 × 1 × 0.2 × 0.13 × 1 × 0.2 × 109 = 15,600,000"
The next bit of the wiki though asks "Has intelligent life ever existed?" - and attempts to answer this ;-)
Great Filter - Wikipedia
"states that since there are no observed extraterrestrial civilizations, despite the vast number of stars, then some step in the process must be acting as a filter to reduce the final value. According to this view, either it is very difficult for intelligent life to arise, or the lifetime of such civilizations, or the period of time they reveal their existence, must be relatively short."
Thought this was going to be a thread about the Thameslink trains complaints process...
Disappointed of Middle England.
