Coal, mostly made of carbon, is the chief cause of pollution.

So would the world be a better place without carbon?

No, the world would not exist without C. It is so pervasive that it is at least a partial constituent in over 90 per cent of all chemicals known to man. Indeed, its electron-bonding properties grant it a versatility (specific only to carbon), allowing it to be the reason for life on earth.

A particle cannot be in two places at the same time 

Distinguished saints are said to have had the power of bilocation. They were reported to have been in different places at the same time.

The world would not exist without carbon. It is a partial costituent in over 90% of all chemicals

Can this happen?

On the nano-scale, in quantum theory a similar hypothesis is assumed. It is claimed that a particle can appear to be in two places at once – a paradoxical phenomenon known as superposition – and that two particles can become ‘entangled’, sharing information across arbitrarily large distances through some still-unknown mechanism (see Photo of the Week). Weird though this seems, this concept has been experimentally validated countless times on quantum scales.
