Will We Ever Find and Understand Extraterrestrial Messages ?

Admin Extraterrestrial, space, Technology 0 Comments

We have been searching for signs of extra-terrestrial life for the last 50+ years, and so far we have found no evidence of anything beyond our planet. But what are we searching for?. We are framed by our own human expectations, our current technology and understanding of the universe and the physics that we believe make it. In other words, we are looking for what we might expect other beings like us, might send and use technology that we know about. The first problem is that if we got a signal or message from ET, could we understand it. Would …

Nasa's Million Dollar Space Pen vs The Soviet Pencils

Nasa’s Million Dollar Space Pen vs The Soviet Pencils

Admin Science, space 0 Comments

The story of the NASA’s million $ space pen and the soviet pencils has become one of the enduring tales  from the space race which still floats around the internet today and goes a bit like this. During the 1960’s as NASA was sending the first men in the space, they realise that pens don’t work in zero gravity, so they spent years and millions of tax payer dollars to develop one that did. Meanwhile, in the Soviet Union, the cosmonauts simply used pencils. The moral of the story to many is that NASA was a wasteful government organisation that would …

Admin Rockets, space 0 Comments

In the history of space, one rocket stands out as an icon of not only the space race but of the mighty power it symbolised. That one rocket, which is still the Tallest, heaviest and most powerful ever built, was the Saturn V, which was designed to take men to the moon and later launched the first American Space station, Skylab. But if things had been a little different back in the 60’s we might have had a different rocket to hang on the bedroom walls of the space fans of the 70’s and 80’s. In the early 1960’s, a …

Why is the Sun hot ?

Why is the sun hot?,  now before you jump on the comments and say “because it’s the sun, stupid” think about it, our sun is basically a giant nuclear reactor at the centre of our solar system but not like the ones on earth. They create energy by nuclear fission, that is they split large atoms like uranium into smaller lighter ones and in the process it releases large amount of energy. Atomic bombs also work in the same way which is why they are so destructive. The sun creates its energy by nuclear fusion, the most efficient way to …

Why cant you fly a plane into space?

Why can’t we fly a plane into space ?

Admin planes, space, Technology 1 Comment

  Why can’t we fly a plane into space, what stops it from just flying higher and higher until we are in space? Well, there a several issues but assuming we are in something like a normal jet airliner, then one of the main problems is the air or lack of it as we get closer to space. A plane flies because as it is propelled forward, the wings, which are shaped to make the air flow faster over the top of them than the bottom, generate lift. As the plane goes faster the wings creates more lift and when the …
