The Tsar Bomb

Some of you may know about the devastating Atomic bombs dropped on Nagasaki and Hiroshima in 1945 during WWII. If you thought those were big, well then... think again.
That is a graph comparing the radius of the fireball of different bombs detonated. The little pink circle is the bomb dropped on Nagasaki. The other graph is showing the comparison of the mushroom sizes. The Tsar Bomb is so big compared to Hiroshima that Hiroshima has to be magnified. Tsar Bomb's mushroom cloud reached an astonishing 64 kilometres high. It was originally designed to be 100 megatons of TNT, but was reduced to 50 megatons ( 50 million tons ) because the fallout would have been to devastating. Some sources say the yield was estimated at 57 megatons, but all Russian sources since 1991 state that the yield was only 50 MT. The Tsar Bomb was so powerful it sent shock waves around the world three times. It was dropped from a modified TU-95v plane on the 30th of October, 1961. This link is a youtube video of the actual detonation at Mityushikha Bay. The purpose of the test was to intimidate the Americans (it was tested during the Cold War) and to prove that if the Russians missed the target, they could still obliterate it.

Is time travel possible?

After a bit of thinking over a few days, I reached a conclusion. You can, theoretically , travel to the future. I will try to explain this to you clearly.

People can only see the light of your body, and not your body itself. Because we move slower than the speed of light ( which is approximately 300,000 kilometres per second ), our body's are visibly synchronised with our physical state. But what would happen if you were to move faster than the speed of light? well first, you wouldn't be able to see anything. It would all be black. That is because light can not catch up to you. So lets say your speed is twice that of light, and you travel for 1 hour
... ... Your physical position : >>>>>>>>>|
Your body's light's position : >>>>|

The speed of light is about 1,079 million kilometres per hour. So if you travelled in a rocket constantly going twice the speed of light to a point 534.5 million kilometres from earth and returned, it would take you one hour to physically arrive back on earth. But because you were going at twice the speed of light, your body's light (or your "visible being") will arrive back on earth two hours after your departure. If as soon as you got back to earth, you have a coffee and sit down to watch a bit of television then leave, people will see you having a coffee and watching television an hour after you actually do it. You will not physically be there, but your visible being will. If someone touched your visible being, their hand would go straight through your visible being like it would a ghost. While people are fascinated by your "ghost" you would be somewhere one hour in the future. As soon as you stop travelling faster than light, your body will become visible. You will have a ghost though, sort of like a clone. The ghost will do anything you do, only an hour later. It would be impossible to go back in time, and your 1 hour delayed clone/ghost will remain for ever, even after you die.

notes : after you stop travelling faster than light, you should be able to see things again.
In this example you have travelled one hour into the future. Feel free to comment if you are confused by anything. I even confused myself while coming up with this.

Ridiculous predictions from the past

There have been many predictions of the future, from the past. Almost all of these predictions were wrong, or we are at least still waiting for them to happen. A lot of these predictions were made by top scientists and engineers, world leaders and and the heads of powerful organisations. Lets take a look at these predictions, shall we?

-Arthur C. Clarke, a British inventor, wrote in Vogue magazine in 1966 saying that all houses would fly by the year 2001.
-What about in the movie Back to the future: part II, which featured hoverboards and flying cars in the year 2015? thats only 6 years from now, so for this prediction to become a reality, The first commercial flying cars and hoverboards would most likely have to already be in the market.
-Here is a prediction that sort of came to reality, The answer machine. In 1964 someone predicted an invention called The answer machine. It was thought that the user would type in a question or topic on a typewriter keyboard, and a screen on the wall would in front of the user would display the answer or videos and photos of the topic. Today, many people use something that has a much similar purpose, and real results. We know it as google.
-Another ridiculous prediction. "By the turn of this century, we will live in a paperless society" Roger Smith, chairman of General Motors, 1986

So the next time you make a prediction, you may want to consider the possibility of keeping it to yourself to avoid embarrassment

New blog and some presents (for you)

Sorry its been a while, i got up to a few things in the holidays and couldn't really get around to blogging, so, here I am. a lot has happened over the time since my last post, but fortunately you won't have to sit through all that. Firstly, return to Matainui.
As you may have seen on my sustainability blog you will have heard about the Matainui island. Well now we are going back on a 2 week field trip, and you can follow my story of the adventure on my new blog. The island has never been touched by human civilisation, and is most likely inhabited by thought to be extinct birds!
I also have a little gift for you all, lucky you. Just a few games i quickly put together in my leisure time, but you will have to download them. Don't worry, no viruses, there not to big, and they are (should be) entertaining. you will find the links below. Remember they are all my own creations and that should probably explain any poor quality you experience.

Game 1 - 2d Air hockey
instructions: Use the mouse to move your air hockey thing ( I am not certain what it is called ) to hit the puck. There is no real aim, score as many goals as you can.

Game 2 - Click the angry face
instructions: Click on the yellow angry face as many times as you can. But the more times you click on him, the faster Mr. yellow angry face darts around the room.

Game 3 - Invisamaze
instructions: Guide your cool electric blue marble through an impossibly hard invisible maze using the arrow keys. I finished the game once. Probably only because I designed all the levels, but I bet none of you can beat it!
