George's Black Hole

By Wednesday teatime we were all still alive and not sucked into a black hole where we are crushed into nothingness or forced to play parallel universe football. It is all a bit on the disappointing side really.
In actual fact our house is a bit like being in a parallel universe right now because my baby brother, George is on the move. He is like a black hole. He sucks us all into his horrible baby world and now we cannot escape and soon he will crush us into nothingness.

First off
. He goes everywhere and we all have to follow him because of the terrible, terrible danger lurking at the edge of every cupboard door, table corner and under every cushion.

Look out! Run from the fluffy cushions!Aaaaaghhh!

Second off. It is The Rule that George is not allowed to put small things into his mouth because:
a
. he will
swallow it, be poisoned and die
b. he will try and swallow it, choke and die
c
. he will not swallow it, stick it up his nose and die
.
But nobody has told George The Rule because a very bad thing happened.

Mum plopped George into my room, without asking me. I know this because when I go into my room he is there, wobbling a bit as he stands up, hanging onto the stick insect table.
'Oi!' I say, 'what you doing?'
He does not answer and my insides go into a kind of
freefall and I know something bad has occurred. Crunch. The it comes to me and suddenly my room is a million miles wide as I race across to save him.
Too late.
Sticky, my best stick insect is prodding out of George.
His front legs are waving a bit like he is saying goodbye before he disappears into the black hole that is George's mouth.

Sticky, before the bad end.

Greetings Time Travellers!

So, we are late getting to The Museum because Mr Trundle made the coach stop while he hunted down his wig. When he put it back on his head EVERYONE stared because it looked as though the top of his head had exploded. Mr Trundle just carried on. By the time the coach breaks down half a mile from where we should stop, Mr Trundle has used his shoelace to strap his wig down. He is a mad genius.

Inside the museum, a tall man called Peter dressed in Viking uniform, says,
'Greetings, time travellers! You're late. We need to catch up with our schedule, so gather ye round!'
He makes a list of instructions which mostly involve not touching anything and not eating near the exhibits or eating the exhibits and not straying from our group leaders.
'Here are your worksheets. Enjoy!' he says to finish.
I look at Dexter and he sticks a finger in his mouth and gags. Unfortunately, Mr Trundle hears him.
'You're not going to be sick as well are you?!?' he asks in a voice which races towards the end of the sentence. 'Sick? Sick? I'll open a window!' I think he is traumatised.
'NO!' shouts Dexter. He rolls his eyes at me. 'I hope we don't get him as our group leader.'
'He is our group leader already,' I tell Dexter. 'That is why he started talking about fishing to you.'
Dexter's eyes go big with horror. 'Now I AM going to be sick.'

Isambard, Dexter, Miranda and Me trundle round after Mr Trundle. He has colour coded our way round the Romans, Vikings and Victorians but in the wrong order. I cannot hardly think about what happened next because it is not nice. I will write it down for next week. I can tell you that Roman centurians and bad wigs do not mix. In the meantime here is a bit about a possible way of time travelling using black holes. I do not think Peter will have done this.

Time Travelling with Black Holes can be Dodgy

When stars are so absolutely massive they run out of puff and collapse. This implosion creates black holes. They have really strong gravitational fields. It is so strong that nothing can escape. Not even Mr Trundle's wig. Around the black hole is an event horizon. If you even touch it you will be sucked in never to escape. Aghhhhhhhhhhhh!

Here is an ice-cream cone. The top bit is the top of the black hole and the cone goes down to a singularity. Here, everything goes mad. If you travel down this ice cream cone, bad luck, you will be crushed beyond recognition. He-he-he. BUT if you get sucked into a rotating black hole, you can start shouting for joy because you might just come out of the other side in a different time and space. This is what a scientist called, Kerr said. Some people do not believe him but I do. It is fantastic.
