Scientists at the University of Sussex have measured a property of the neutron -- a fundamental particle in the universe -- more precisely than ever before. AS DOUGLAS ADAMS once wrote: “The universe is big. Or to put it another way: why does anything exist at all? According to NASA, after inflation the growth of the universe continued, but at a slower rate.

Wherever they look, throughout all the Universe, or across the particles in their Accelerators, we keep finding tat it seems to be finely tuned to grant us our existence--specifically, Human existence.

THERE is plenty to recommend the standard model, our best description of particles and their interactions.But it has the odd awkward lapse. But there might not be an absolute answer to why it exists. By the same logic, nothingness is the highest entropy state around – you can shuffle it around all you want and it still looks like nothing. Scientists at the University of Sussex are measuring a property of the neutron—a fundamental particle in the universe—more precisely than ever before. Scientists at the University of Sussex have measured a property of the neutron—a fundamental particle in the universe—more precisely than ever before.

It’s a big question, perhaps the biggest. Some dismiss these questions, thinking them idle. As space expanded, the universe cooled and matter formed.

Their research is part of an investigation into why there is matter left over in the universe, that is, why all the antimatter created in the Big Bang didn’t just cancel out the matter. Scientists at the University of Sussex have measured a property of the neutron – a fundamental particle in the universe — more precisely than ever before.

More logical, to me, is the bubbling, frothing multiverse situation—but okay, we still then have the same problem. The search for the origin of life: From panspermia to primordial soup. Around 13.7 billion years ago time and space spontaneously sprang from the void. It is not clear that we can even speak coherently about the creation of the universe, given that such an event can be conceived only with reference to time, and here we are talking about the birth of space-time itself.” Scientists at the University of Sussex have measured a property of the neutron - a fundamental particle in the universe - more precisely than ever before.

The idea that the universe simply appeared out of nothing is difficult enough; trying to conceive of nothingness is perhaps even harder. According to the hypothesis, the universe appears fine-tuned for intelligent life because of the anthropic principle, with most universes being devoid of life. If this universe is the only thing there is, that’s kind of weird and illogical—why would this big space just exist by itself in an otherwise nothing situation?

To investigate why all the antimatter created in the Big Bang didn't just cancel out the matter, the researchers have looked into whether or not the neutron acts like an "electric compass." Entropy measures the number of ways you can rearrange a system’s components without changing its overall appearance.
