“One is the comment that we can see galaxies 13.8 billion years ago.
No one explains how the further out we look we find galaxies and stars That we compare to our own even though they have not existed as such for 13.8 billion years.”
The universe is much larger than 13.8 billion years across due to space expansion, the most recent estimate I have seen is around 95 billion light years.”

Size of the visible universe is partly dependent on how good our “optics” are.
If something is out there 14.2 billion light years away we probably would not see [detect ]it with our current science.
As DM said “How bright would a mega star have to be”.
Even other universes from other big bangs [if we consider our “universe” to have a single origin would be hard pressed to trouble the cosmic microwave background radiation let alone be seen.

The size of the visible universe is thus only double the 13.8 billion years, 27.6 billion years.
Since it has been expanding at less than the speed of light [caveat] the actual universe would be only perhaps 54 billion years old at the moment.

“The universe is around 95 billion light years across.” is an estimate based on maths and physics theories and until everyone agrees on those we might be better sticking to the speed of light time and distance observations.
Thank you for putting it and the concept up.
The big bang itself had so much matter and energy that our current concepts of time and the speed of light back then go out the window.

“As I understand it, the galaxies in the galaxy cluster that was imaged by JWST were about 4.6 billion years old”.

The articles being written by journalists seem to be conflating such galaxies with the concept of being able to look back a lot further in time.

The original hot explosion or event being that long ago that the first clumps of plasma for want of a better word were supposed to form mega stars of very short life span which threw out clumps of matter [including some heavier elements than H, He] to form the original galaxies which were also very large [hence visible faintly] and then possibly another two iterations to get to our young star and young galaxy.
The materials greater than iron on the periodic table, gold being the best example, are thought to have come from arcane processes in past supernovae.

It is hard to imagine our sun being the remnant of a 13.8 billion year chunk of hop plasma cooling down over that length of time.
Further such explosions cause escape speed velocities which mean that the galaxies should never have come back together.

An alternative view is that space was filled with large amounts of cooled down matter in waves of explosions that crossed each other causing focal points of reaccumulation resulting in newer smaller galaxies.
This would explain suns forming from gigantic masses of cold hydrogen, etc hitting or passing through each other leaving focal eddies of matter which could then coalesce to form suns and planets.

and how elliptical orbits of planets and stars can come into being.

Thanks angech

Rotary speech 13/7/2022 Role of Chairman

Dear fellow Rotarians

Could I ask you all to stand and join me in drinking a toast [invocation

For good food , good fellowship and the opportunity to serve rotary, we give thanks


Now I will ask the sergeant of the day, Ian Powell, to give the Loyal toast

Ian Powell
[“To Rotary International and Australia.”]

Thank you Ian

and you will always be sustained by the fellowship and esteem of us all.

welcome back to our first meeting following a changing of the guard last week.
I note that the ROTARY THEME FOR July This month’s theme is New Leadership Month

Some small steps to go through
I welcome everyone here today especially our new President Andrew, our new Paul Harris medal recipient, Danny, and especially our new member, Phil Stammers.
We also have present our past District chair Laurie Fagan and his wife anne
and other Rotary club members geoff and tracey.
I would like to call on Rotary members present to introduce their guests.
Phil [wife]

I will now hand over to Ian to conduct the meeting


starting with any announcements from club directors and any news that members of the club would like to share business for the day.

I will hand over to the Sergeant of the day for our fines session.

Check that the person introducing the guest speaker is present [me]
and has received the speaker’s resume
and has sufficient information to give a dignified introduction.

Check that the person doing the Thanks to Speaker [me]is in attendance and has the certificate or gift, as appropriate in your club.

THE FOUR-WAY-TEST … What does it mean?
For Rotary, The Four-Way Test is the cornerstone of all action. It has been for years, and it will be in the future. Of the things we think, say or do
Is it the TRUTH? Is it FAIR to all concerned Will it build GOODWILL and BETTER FRIENDSHIPS? Will it be BENEFICIAL to all concerned?
The test is one of the hallmarks of Rotary. Since it was developed in 1932 by Herbert J. Taylor, who later became RI president, it has never ceased to be relevant. Its four brief questions are not based on culture or religion. Instead, they are a simple checklist for ethical behavior. They transcend generations and national borders.
As Rotarians, we should have The Four-Way Test in mind in every decision we make, all day long.
Rotary is dedicated to causes that build international relationships, improve lives, and create a better world to support our peace efforts and end polio forever.
We now have a new President, Andrew Pogue ,who will be to carry out Rotary’s Objective,
with its five avenues of service as a constant guide.
It is also the day on which we ask our new member Phil Stammers to tell us a bit more about himself.
It is with pleasure that I now extend to you the right hand of Rotary fellowship & give you a hearty welcome as a member of the Rotary Club of_S Central
Before we go further can I mention our guests for today,
would also congratulate past President Danny Hogan on his second Paul Harris Medal
