Who's watching you?

 

There's a rumour going round here, from a friend who studies outer-space and visitors from other planets, that aliens from other worlds have landed here and are able to take the form of animals in our homes and farms. A bit like the shape shifter named Odo in Star Trek. Do you remember Odo? He could change his shape into anything or anyone.

Well, according to my friend, Ivor Anomaly, space aliens have landed on our planet years ago and take the shape of our pet dogs, cats or farm animals; parrots even, or birds in your garden. This way they infiltrate our lives and observe us quietly and send back information to their mother-ship parked nearby in the shape of a tree, trash bin or even a fire hydrant. Just like the telephone box in Doctor Who's Tardis.

Have you noticed how sometimes your dog would look at you intently with his head tilted to one side? He is gathering information ready to transmit to his colleagues nearby; like the recipe of your favourite cookies whilst you're baking, or the items on your shopping list.

Ivor warns us to be careful whilst undressing in front of our pets. They look confused at first and think that we are shedding our outer skin; yet all the time they are transmitting all they see to their spy satellite nearby. Also, never take a shower or have a bath with your pet dog or cat watching you. It may well confuse him and send the wrong information to his colleagues.

Another friend of mine is convinced that his new memory mattress is in fact a shape shifter from another planet because the mattress is now blackmailing him about who he had in his bedroom. 

Mrs Fathead from 15 Acacia Avenue down the road told me that her dog turned her husband into French fries and then ate him off the dining room table whilst she was on the phone. She hasn't seen her husband since they had a row that very morning.

There is as yet no evidence that shape shifters can look like inanimate objects like your clothing, or shoes, or the lamp stand. But people are wondering how sometimes you seem to have lost your car keys, spectacles, TV remote control and other things; and they are not where you last left them. Is it a space alien moving from one place to another, one wonders? 

In summary, be careful around your pets as they may not be what they seem. Were you there at their birth? How can you be sure they are not from outer-space?

SpaceTime

 

Today we shall discuss SpaceTime. An easy subject to understand if explained by me rather than Einstein.

The Earth is spinning round itself as well as going round the sun in about a year or so. It is moving through "Space".

Let us say that on 1 January 2010 the Earth was at this particular point in space. We can pinpoint the exact place the Earth was on that day. We will call this Location 1 (L1). And we will call 1 January 2010 Time 1 (T1).

So on 1 January 2010 the Earth was at L1T1

Now on 1 January 2022 (12 years later) the Earth was at a point in space. It may or may not be the exact location as before. Let's say it was the exact same location. So we can logically call this Location L2 which is exactly like L1. 

L2 = L1.

However, even if L2 = L1, because of the passage of years the time point on the calendar has changed. 1 January 2022 is now T2. So we are now at L1T2 which is different to what is was before L1T1.

So what we are saying is that even though the Earth could get back to the same point in space in the future; because time is always moving the Earth can never be in the same point in SpaceTime as before.

That is, it can never be in L1T1 again. Even if it manages to be in the same spot in space (L1) it will never ever be in the same point in time. Time has moved on. It has gone for ever. Time will be T2, T3, T4 and so on.

And that's what we mean by SpaceTime. Various points in space at a particular point in time.

Now here's the theory by some clever scientists.

They say because the Earth, (and you), have moved on it does not mean the previous points in SpaceTime have vanished. They are still there but unseen by you.

For example: On 1 January 2010 you were at home enjoying New Year's Day. And we called that L1T1.

Today, at this time you are somewhere else. Hopefully reading this post, otherwise I'm talking to myself here!!!

Now scientists say you can (theoretically) travel back to L1T1 and see yourself enjoying New Year's Day. It's called time travel. They claim L1T1 still exists and has not gone away with the passage of time.  

Many years ago there were a number of Lyons Tea Houses in street corners in London. People used to go there and enjoy a pot of tea and scones with clotted cream and jam.

I went to London recently. There were no Lyons Tea Houses there. Exactly the same locations as before, but a different point in time.

So I went to the pub and had a Guinness.
