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.
