It all started with a big bang 13.8 billion years ago

The universe is a strange and wonderful place, primarily empty space with a smattering of galaxies scattered about. Each galaxy has hundreds of billions of stars and the universe itself is so vast that it has one hundred billion galaxies. The enormity and scale is impossible to get our heads around and it takes rare geniuses like Einstein, Newton and even Hawking who have the uncanny ability to visualise, scrutinise and probe the depths and workings of the universe. Even the nearest star to us is 4 light years away, which in layman’s terms is a staggering 40 trillion kilometers, that is 40 with 12 zeros after it. The Voyager 1 spacecraft, launched in 1977 to study the solar system travels at 62,000 km/h. At this speed, It would take 73,000 years to get to the nearest star and a cool 640 million years to get to the centre of our galaxy!

Genesis – Is life really common?

Did life start in a warm little pond just as Darwin thought?

Scientists have made some tremendous advances in recent years. Biologists are discovering that life is not as delicate as we once thought. No matter where on Earth we look, we seem to encounter life. Hardy bacteria that can thrive in the harshest of conditions. From the extreme heat of thermal springs and deep sea hydrothermal vents to the harsh conditions found in nuclear reactors, bacteria and other microbes find a way to prosper. We have exposed bacteria to the harshness of space on the outside of the international space station, only to discover later that the bacteria hadn’t been killed off, but had survived the exposure and were able to grow again upon return to normal conditions.

Heavy metals

The immense power of a supernova makes gold amongst other elements.
The immense power of a supernova makes gold amongst other elements.

Incredible news reports last week revealed that scientists have observed two neutron stars colliding in a galaxy 130 million light years from Earth. Not only that, but the power of the collision set up gravitational ripples in space-time, which eventually made it to us here on Earth.

Cassini mission winds down

An Iconic Saturn image from the Cassini mission
Saturn, Lord of the rings. An iconic Saturn image from the Cassini mission

Launched in 1997, the Cassini mission to Saturn sent it’s final images back to earth last week before plunging into the planet in a planned manoeuvre. It spent 13 years in orbit around the ringed planet, carried out some spectacular science and beamed some great images back to earth.

Zapping the pounds away

If all else fails, simply zap the fat away with a Modius headset
If all else fails, simply zap the fat away with a Modius headset.

Being on the large side, means I always take a keen interest in the latest diet fads and technologies to see if there is an easy way to shed some of the excess pounds. Of course, I could simply eat less and move more but that sounds very dull and not at all interesting, so I have been quite successful at ignoring that option and waiting for the ultimate diet to come along.
