I can’t understand why there is so little interest in the republican debate. Is it because it doesn’t matter? We should all have a keen interest because it is at the heart of us being an independent country.

Despite increases in living standards and access to technologies, like the internet and social media, measures of happiness haven’t increased. Is social media making people feel connected but actually making them more isolated?

The concept of light years, billions of stars in our galaxy and then billions of galaxies outside of the Milky Way is just too big to get a grip on. Maybe there is another concept of distance in a physical law that we haven’t discovered yet, and that will make more sense of these distances and scale? Maybe the micro-world is as big relatively to the universe, that is, the relative distances between individual components of atoms and molecules is just as vast as the universe is big? How can there be an end to the universe – where is it located if it is confined in some way? We know so much – why don’t we know this?

Loneliness is something that I have been grappling with lately, and I have noticed an up-tick in think-pieces about technologies effect on social relationships between people and a loss of community. The connections people have with others has been a perennial interest of humankind.

Mostly because it’s fun, but I wonder about the benefits of unstructured, inclusive and spontaneous activities that allow people to experience themselves without purpose.

Because new waves of migrants continue to make healthy, happy new futures in Australia while the Aboriginal people seem to suffer continued low employment and poor health.

Whether it’s gun control or bicycle helmets, Australia’s Common Law leads to a duty of care. What would the world look like if this was adopted internationally?

This is the elephant in the room whenever the question of vaccine safety is discussed on public media.
I that people who are coerced into vaccination by public campaigns have the right to know accurate information about the safety and effectiveness of vaccination.

Scientists tell us about the big bang and how this world began but I’m not sure about the ending. Do scientists know?

This has been a conspicuous problem with the Howard and Abbott governments, but always a potential one. In the case of climate change it is particularly pressing to take positive action ( see Naomi Klein -This changes everything). Refugee policy would be another issue.
