In what direction is the universe expanding?

A little bit OT, but the concept of time always intrigues me. I swear some universal Fat Controller is accelerating time.

As I get older, events seem like they happened yesterday. Two prime examples the advent of COVID - it feels like it started a year ago. Another is when I broke my ankle in September 2018. In my strange world, it occurred two years ago. Remember when Christmas school holidays took forever? Now a two week holiday lasts for a few days.

I have a hare brained theory about this. As you get older, the proportion of a certain length of time decreases as time progresses. For example, a four year old kid sees one year as being 25% of his entire life, while his 40 year old father sees the same time period as being just 2.5% of his life. It's a bit difficult to explain but hopefully you'll get the gist of it.
Interesting mate, I understand where your coming from.
My dad's favourite sayings were, "I'm in a hurry to go where" and "hurry up and wait"
In a way time is measured by ones mindset. If you were floating in space, time would go really slowly especially if there wasn't anything to focus on but if you only had an hour of oxygen left it would go pretty quickly I would imagine.
Time goes quickly when your busy too. Do I Cram it in and make it fulfilling then wonder where my life went or be a lounge lizard and read a lot. :rolleyes:
All these posts are great reading and highlights man's inquisitive behaviour. We don't like not knowing.
Our thirst for knowledge begins before we start walking and never stops...I think that is the essence of life.

Being an avid hardcore science fiction freak and having watched hundreds of movies and read thousands of short stories and novels, I recently acquired the urge to write something myself.

One story is about the real cause of climate change and the other is about the ramifications of time travel. I'll deal with the latter in bare bones form.

"In the not-so-distant future, Man has perfected time travel into the past. Firstly, it was used by historians to witness past significant events to verify what really happened.

"Then some misguided souls decided to use it to change past events, usually for their own benefit. This was outlawed before it got started.

"Next was the advent of time travel tourism where a group of individuals would travel to a time of their choice such as the rise and fall the Roman Empire, the assassination of Abraham Lincoln and to see the life of the Neanderthal in the flesh. There were strict rules regarding this so as not to change the course of the future from that time onwards.

"On the year 2048, one group decided on seeing the Age of the Dinosaurs. As all other time travel excursions, the participants travelled on floating platforms so as not to disturb the ground or vegetation.

"As the group observed Brontosaurus, Tyrannosaurus Rex and Triceratops in all their glory, one participant had a huge dragonfly land on his leg. Instinctively, he swatted it and grounded it into the platform floor.

"When the group returned to their time, something was not right. The wall clock only went to 10 instead of the usual 12. The electronic calendar read '5 Màrz 103' and all the signage was in German."

I will let that sink in for a moment and I'll come back tomorrow if you haven't already worked it out.

The old paradox of time....

"My mother told me that my father was a real arsehole as a teenager. I think might go back to 1955 and kill him.

"Hang on.... if I kill him will I ever be born??"

Mind boggling stuff.

And now for the great reveal....

The primary clue is in the years mentioned. The year 2048 is 103 years after the end of World War II and new calendar shows "103". History was significantly altered so the allies lost and Germans won. The Third Reich restarted the calendar to recognise their victory. And the German signage is self explanatory.

The 10 hour clock may be seen as the metrification of time (which makes sense to me).

I suppose those who are reading this already guessed the punchline. The moral of this story is that a small change in the past compounds itself to become a huge change in the future.

I am heavily influenced by Rod Sterling's The Twilight Zone so it might be time to watch them for the 5th or 6th time....

....all 156 episodes in glorious black and white.

Yes, good viewing.

Much more creative and interesting than the reality TV and mind numbing stuff TV serves up these days.

I don’t give a f**k about dumb people in a jungle trying to start a fire with a sex toy.

Prefer wondering why we haven’t been hit with more asteroids.

Man you guys have awesome imaginations but going back in time to watch a Neanderthal poop is too much.
You talk about changing one thing in the past can change everything in the present and the future. Same really goes for changing/excluding molecules, atoms etc. I guess ever who invented bacterial matter is the real god.
I'll punt on the egg because it's simple in form.

Not for the faint hearted....

On the touched-on topic of time travel, ramifications, and science fiction, there's a Queen song called '39, written and sung by guitarist Brian May. A science-fiction/folk song (a strange combination, but it works) all about the hypothesised time dilation effect of travelling at the speed of light.
A group of space travellers set off to find new lands, travelling at the speed of light. When they return to Earth with their news and discoveries a couple of years later (to them), they realise hundreds of years have passed back on Earth and all their loved ones are well and truly dead and gone.

Great song too.

I recall reading that the Apollo astronauts experienced this phenomena but I'm not sure of its validity. Their body clocks were apparently a couple of milliseconds out compared to Earth time.

I read about it over 50 years ago so it's all a bit sketchy to me. Time to do some research methinks.

I think Mercury doesn’t spin about on an axisey thing.

So half of the planet is freezing all the time and the other half scalding.
The smallest planet in our solar system and nearest to the Sun, Mercury is only slightly larger than Earth's Moon.



From the surface of Mercury, the Sun would appear more than three times as large as it does when viewed from Earth, and the sunlight would be as much as seven times brighter. Despite its proximity to the Sun, Mercury is not the hottest planet in our solar system – that title belongs to nearby Venus, thanks to its dense atmosphere.

Because of Mercury's elliptical – egg-shaped – orbit, and sluggish rotation, the Sun appears to rise briefly, set, and rise again from some parts of the planet's surface. The same thing happens in reverse at sunset.

If we are solar systeming thought I’d put in a good word for Venus:


It’s interesting that we find the similar elements on other planets etc.

It’s a pity that we have spend all these resources on war and conflict when we should be shoving it in to medicines, housing, food, education and space exploration.

It’s strange that the terrain of Venus seems to resemble the broken concrete of a carpark at a pub in the country.

Which of course is my vote for the 18th side.

NSW country, with multiple home grounds in Dubbo, Parkes etc.

That would be much better for helping the community and indigenous folk.

Two sides later, we can introduce a second division where the Tigers can come last annually in peace.

There was a set of American twins of which one was an active astronaut and spent a considerable time on the International Space Station. The other twin was the experimental control according to a NASA report on changes to the human body while in space Apparently he aged about five milliseconds less than his earthly sibling.

If anybody is interested, here's a bit of light reading.

I will suss it out tonight thanks.

Peace coming last for the Tigers forever more,

No anxiety associated with winning, no broken promises. Just a comfortable eternal last place, the stuff of stars.

In the universe of things, it’s just another concept.
