Left side of the Universe

sketch-1575306063238

This was a phrase I thought of this afternoon, then realised it was impossible.

The Universe is apparently infinite, so you can’t have a centre, you can’t have a top, bottom, side, front or back?

Obviously we know that stars are a certain distance away, and if you look at star maps you can identify individual stars. But did you know they move? Stars move around the centre of the galaxy. Some faster than others. The distance to a star is measured by parallax. Hold your hand out at arms length, look at the tip of your thumb with one eye, then the other. Notice how the background seems to move. That’s because each eye is at the base of a very long thin triangle and your thumb is at the tip. Now think of the stars. How do you measure their parallax.? The answer is take the measurements at opposite sides of the Earth’s orbit, six months apart.

What was found was the stars are not fixed. They are moving due to the matter around them and their relative speeds. So stars in one position a thousand years ago might have moved quite a distance.

That’s not all, the Galaxies that contain the stars are moving too. Some, like our galaxy, the Milky Way, and the Andromeda galaxy are due to collide in the next few billion years. We won’t be around to see it, but it has been modeled.

Then looking further out Galaxies seem to be flying away from each other at a rapid rate. You would think gravity would hold them together, but something in the Universe, (dark matter, dark energy) is pushing it apart.

This was measured by noticing the galaxies light from further away appears redder ( red shifted). In other words travelling away from us.

To explain, if you hear a fire engine siren it sounds different moving towards you than moving away. That is because the sound waves get squashed up as they move towards you, and stretch as they move away. Light does the same thing, as an object moves towards you it squashes up and changes to a bluer colour. As it moves away it stretches and we see a redder colour.

I’m not a scientist, so I can only hope what I’ve written makes sense. All I know is that something might be in an exact place now but because everything is in constant motion you just can’t say where the ‘left side of the universe’ actually is!

Waiting

FB_IMG_1571531733931

Does time splinter into different universes? While I sit here waiting for my hubby, who insisted he wanted to walk home in the rain after I dropped him off a couple of hours ago for an appointment, I wonder, where has he got to? Is he OK. Which way is he walking home. Might he get lost? He has problems following directions. But if he knows the way (and he walked back last week) then he should be OK.

But he mooches, he likes looking at things, he doesn’t stride out anymore. He’s not young. I want to go and look for him but the traffic outside is at a standstill. So I’m sitting waiting, worrying, fretting, he’s a grown man. I know he will be OK.. I guess. But time fractures, things happen….

Ten minutes later.. He’s back!

Observe

Photo of Jodrell Bank Observatory I took in 2011.

See that star up there?

That’s a planet Galileo saw.

See the dots across its face?

Moons that circle it apace.

Moving further into space,

Stars and gas, nebulae like lace.

Gazing further, higher, far

Supernovae, neutron star.

Galaxies fly apart so fast

Hubbles constant, Doppler’s haste.

Black holes tug at other worlds,

Gravity wells where stars are hurled.

Big bang  was expanding

Dark matter we’re  not understanding..

Cosmic microwave background energy.

Look out from our earth observatory.

 

Shouting in the dark

Untitled55_002

I’m too small

The world’s too big

Shouting in the dark,

 

The world’s too small

Solar system so big,

Shouting in the dark,

 

Sun’s system is small

The galaxy is big

Shouting in the dark –

 

The galaxy is small

The universe is big

I’m shouting in the dark.

 

Shouting into infinity.

Is anyone out there –

To hear?

This took a few hours to draw on the old sketchfu website. I do love astronomy. This is not accurate, it couldn’t be with the limited tools that were on the website but it was fun to try and get a reasonable representation of it. Space is so infinitely beautiful. It makes me realise how tiny I am, how small our planet and solar system are in relationship to the mass of stars in a galaxy and the smallness of galaxies in relation to the infinity of the universe.

How important we think we are, we have so much on this world that we are using up. We are big in comparison  with insects and smaller still bacteria. Then even smaller viruses. The smallest things, molecules, Atoms  and sub atomic particles.

Apparently we are halfway on the scale of size in the universe. Halfway between the infinitely massive and the incredibly tiny. Perhaps in realising this we can see we are not very important after all. I think we should take more care to preserve our tiny/huge planet so that humankind can continue to survive and flourish.

When cats stare

DSC_1708When cats stare what are they seeing? Why do they look at things that don’t seem to exist. I see him pouncing on things but they are not visible to me. A great big purr/miaow yowl… then a rush and land crash onto a chair or leap over a bag or some books.

Seeing the unseen.. A sixth sense? No smell, nothing to feel, no image. I look in the same direction, nothing.

Can cats see into the past or future? Can they see ghosts? He never hisses and his tail does not thrash from side to side. The look is curious, open eyed. Querying the validity of what he sees.

There is a Shakespeare quote from Hamlet, something along the lines of “there are more things on heaven and that are dreamt of in my philosophy Horatio”

Maybe cats can see through our universe. Maybe they can see into the next….

Sleeping

Untitled28_001

I want to be in my bed

Asleep,

Sleeping, snoozing, snoring, napping.

Tired out

Kaput,

Knackered,

Dozing, having 40 winks

Getting some shut eye

Sleeping under the duvet….

Warm, snuggled, wrapped in feather down

Hushed, soft, moonlit,

Hidden in the dark,

Eyes closed but seeing the stars.

Waves of colour.

Dreaming of galaxies and sun’s,

Nebulae encompassing infinity,

Then shrink down, back to the room,

And sleep.. …
