Leave. I am sick and tired of our laws being made by some faceless central bureaucracy. What do we actually get out general relativity and quantum mechanics? It's all very well if you're a supermassive star aspiring to supernova, but what are the benefits for Earth? And the amount of energy that we radiate out into the universe while all we get in return is cosmic rays that cause cancer and the odd meteorite that wipes out the entire biosphere - why should we put up with that?
Stay in or risk ending up like pluto. It's not even a real planet anymore, just a f*cking dwarf unable to negotiate objects in its path. Has absolutely no influence whatsoever.
Obviously it makes sense to leave, look at the immigration problems we've had over the last few years, mork, e.t,f##king Alf , all those on men in black plus Donald trump and lady gaga, we need to get out now.
In reply to Trangia: I always did think that quantum mechanics was a bit of a wishy washy liberal approach to dealing with particles. Put them in a potential well and they start wringing their hands and bleating about "confinement".
