Should we seed/polute the universe with life?

February 13, 2010

What if mankind could purposefully launch space probes packed with little biological “starter kits” toward star systems that appear to have the potential to nurture life? We have lots of life down here, is it our duty to spread our seed amongst the stars? Read more here.

So should we try and spread life throughout the universe, seed currently lifeless planets with some of our bacteria to evolve. Or would that just be gigantic biological pollution. What do you think?

For a better world we should take Friday off … forever

September 16, 2009

Fancy a three-day weekend – not just once in a while but week in week out?

You may think your bosses or teachers would never agree to it, but the evidence suggests that employers, employees and the environment all benefit.

The four-day week comes in two flavours. One option is to switch from five 8-hour days to four 10-hour days, meaning overall hours stay the same.

The second form of the four-day week is to work the same number of hours per day for four days only, with a corresponding 20 per cent pay cut for employees.

Either way, the hope is that by shutting down buildings for an extra day each week, energy bills would be slashed by up to a fifth. Read more here.

So what do you think? Would you like a three day weekend forever?

One step closer to finding extraterrestrial life

April 22, 2009

In the search for Earth-like planets, astronomers have zeroed in on two places that look awfully familiar to home. One is close to the right size. The other is in the right place.

Researchers said they not only found the smallest exoplanet (planet beyond the Solar system that orbits a star other than the Sun) ever, called Gliese 581 e, but realised that a neighbouring planet discovered in 2007, Gliese 581 d, was in the prime habitable zone for potential life.


Gliese 581 e is only 1.9 times the size of Earth – while previous planets found outside our solar system are closer to the size of our massive Jupiter, which could swallow more than 1,000 Earths.

Gliese 581 e sits close to the nearest star, making it too hot to support life. Interestingly, Gliese 581 d is located within the “habitable zone” – a region around a star that would allow water to be liquid on the planet’s surface. A feature that has made life on Earth possible. Read more here, here, here, here, here or here.

So how long do you think it is going to be before we actually discover life on another planet?

Is there life out there?

February 7, 2009

Researchers have calculated that up to 37,964 worlds in our galaxy are hospitable enough to be home to creatures at least as intelligent as ourselves.


If there are 37,964 planets that could be home to aliens in our galaxy, the Milky Way, I wonder how many there are in the entire universe?

Well, apparently there are about 125 billion galaxies, meaning that there are probably about 4,745,500 billion planets which are able to sustain life. That’s a lot, and I betcha Earth is not the only one with life on it! Read more here.

What do you think, is there life on another planet?

How many bacteria fit on the head of a pin?

October 16, 2008

Bacteria (one of them is a bacterium) are very small organisms (living things). They are so tiny they can only be seen through a microscope. Bacteria are made up of just one cell, so they are a kind of unicellular organism.

My question is:

To help you decide on your answer check out this image of some bacteria on the extreme pointy end of a pin:
