Who do we think we are?

Britain is about the decide who it wants to be. Are we so different from others that we cannot play by shared rules? Are we one member in a family of nations, or a country that prefers to keep itself to itself and bolt the door?

All of these questions were always on the ballot in this week’s fateful referendum. But after a campaign that has been nasty, brutish and seemingly endless, the UK will be voting on another question too.

With all the differences and the diversity among all of us who already live on these islands, how are we all going to get along? In the final run-up to polling day this contest has risked descending into a plebiscite on whether immigrants are a good or a bad thing. Consider the dark forces that could so easily become emboldened by a narrow insistence on putting the indigenous first.

The backdrop has been the most unrelenting, unbalanced and sometimes xenophobic press assault in history. Leading political lights of leave have claimed to be pro-immigrant and yet have, at the same time, been ruthlessly fearmongering about Britain being overrun by Turks, after a Turkish accession which they understand perfectly well is not on the cards.

The mood is frenzied, the air thick with indignation, and clouded with untruths. The best starting point for Britain to reach a sound decision on Thursday is to cool the passions of the heart, and listen to the head.

All reason tells us that the great issues of our time have little respect for national borders. The leave side has attempted to turn “expert” into a term of abuse, but one does not need the IMF, the Bank of England or any special knowledge to grasp that these border-busting issues range from corporate power, migration and tax evasion to weapons proliferation, epidemics and climate change.

Not one of them can be properly tackled at the level of the nation state. Impose controls on a multinational corporation and it will move to a softer jurisdiction. Crack down on tax evasion and the evaders will vanish offshore. Cap your own carbon emissions in isolation and some other country will burn with abandon.

In so far as any of these problems can be effectively addressed, it is through cooperation. A better world means working across borders, not sheltering behind them. Cutting yourself off solves nothing. That, fundamentally, is why Britain should vote to remain in the club that represents the most advanced form of cross-border cooperation that the world has ever seen.

There are certainly flaws in the way that Europe is constituted and led. The EU is a union of nations working together, it is not and never will be a United States of Europe, and so its leadership is bound to depend on the imperfect leadership of all these countries.

The single currency has been a flawed project and has set one nation against another, forcing the poor to pay the price for propping up a shonky structure. But Britain is not part of the eurozone, and the EU is not a plot against the nation state. Britain is still robustly herself too, warts and all.

The only argument about the immediate economic effects of Brexit is the depth of the hit that the economy would take, not whether it would take a hit at all.

The political victors would not be those who wish to rebuild politics. They would be rightwing Tories, and ruthless plutocrats who want freedom to reorder Britain and make money as they choose.

They have no interest in fairer taxes on the rich, or higher spending on the NHS. They have spent their so-called Brexit dividend – which in reality is almost certainly a negative number, not the mendacious £350m a week which has earned them an official reprimand – many times over.

A significant group of them are flat-taxers who are whispering about deep cuts to corporation taxes. Facile Brexiter talk of a more buccaneering Britain – presumably a country fit for Sir Philip Green or Fred Goodwin to capture other galleons – offers precisely nothing to assuage the fears of elderly voters who simply want nothing more to change.

It is a fantasy to suppose that, if Britain votes to leave, these victors would want to maintain or extend protections for pensioners or workers. On the contrary. Human rights, equality, health and safety, and aid to refugees would be out of the window.

Those who vote to leave as a protest against the elite will, in truth, be handing the keys to the very worst of that very elite. There would be no ‘taking back control’ for most working-class leave voters, just less control over their diminishing share than ever.

Those who have not yet made up their mind in this campaign should ask themselves this: do you want to live in a Britain in the image of Nigel Farage? Yes or no? For that’s the choice on offer. If the answer is no, then vote remain.

Thursday’s vote has become a turn-in-the-road issue for Britain and Europe alike. Imagine a world without the EU – without the clout to face down Russia over Ukraine, without the ability to put together coherent answers to carbon emissions, to protect standards at work from a race to the bottom.

Like democracy, the EU is an imperfect way of answering the modern world’s unrelenting challenges. But the answer to its imperfections is to reform them, not to walk away – still less to give in to this country’s occasional hooligan instinct in Europe.

Like democracy, whose virtues are in our minds afresh after the violent death of the committed and principled MP Jo Cox, the EU is not just the least bad of the available options. It is also the one that embodies the best of us as a free people in a peaceful Europe.

Vote this week. Vote for a united country that reaches out to the world, and vote against a divided nation that turns inwards. Vote to remain.

Arizona asteroid explosion

The explosion of a small asteroid over Arizona in the early hours of 2 June is a timely reminder of the unseen and sometimes unpredicable threat facing our planet.

The asteroid hit Earth's atmosphere at around 4 am local time and the airburst cause by its explosion shook the ground below and produced a flash of light 10 times  brighter than a full Moon. NASA described as a three metre wide space rock that originated from beyond the orbit of Mars.

Shortly after the explosion, Mike Lerch walked out the front door of his house in Phoenix on the way to work. "At first I thought it was a rocket launch," he says. "Now I realise it was debris from the asteroid."

The smoke trail remains shown clearly in his picture below were widely visible as they twisted in the winds high above Arizona.

Bill Cooke of NASA's Meteoroid Environment Office says this is the brightest fireball detected in the eight-year history of NASA's All Sky Fireball Network, an array of cameras that monitors fireball activity across the USA.

The flash itself was so bright, it briefly turned night into day, graphically illustrated in these before, during, and after shots captured by one of the NASA cameras in Sedona, Arizona. The camera was facing NE so it did not record the asteroid itself.

The fact that the explosion blinded most cameras that saw it initially complicated analysts' efforts to pinpoint the asteroid’s nature and origin. Ultimately, however, they were able to draw firm conclusions - the mass of the asteroid was some tens of tons and it exploded with a kinetic energy of approximately 10 kilotons.

"There are no reports of any damage or injuries -just a lot of light and few sonic booms," says Cooke. "If Doppler radar is any indication, there are almost certainly meteorites scattered on the ground north of Tucson.”

Dangers posed by asteroids impacting Earth was one of the topics discussed at the 4th Manfred Lachs International Conference on Conflicts in Space and the Rule of Law held in Montreal, Canada, the weekend before.

Comets and asteroids colliding with Earth pose a serious threat to humanity yet we lack effective means to discover them and alert the public to imminent dangers. Even the impact of a small celestial body may lead to serious loss of life, significant material and ecological damage.
