Apparently, we got 65cm of snow here in sunny Scarbourough Ont. on Sunday.
And we allegedly had an earthquake last night.

Did the earth move for you ?

I was sleeping mate. Didn’t notice anything.
Voyagers 1 and 2 will never travel beyond the confines of our galaxy.
They aren't travelling fast enough to escape its gravitational pull, and will eventually settle into an orbit around the central black hole with each circuit taking around 250 million years to complete.

Have you taken Einstein's special theory of relativity into account?
I bowed down to a superior understanding of these things when I read about it, but I found it quite interesting they won't be going on a straight line journey to the edge of the universe.
The first star Voyager 1 will pass in 40,000 years time is a red dwarf that will, in time, given its present trajectory, become the closest heavenly body to Earth, knocking Alpha Centauri into 2nd place.

On my very basic understanding of the special theory of relativity, time is different dependent on gravity. For example, on the International Space Station, time passes differently than it does down here, which basically gives credit to Eintein's theory.

I'm paraphrasing him here...
"If you sit on a hot stove for a minute it feels like an hour,
If a fit woman sits on your knee for an hour it feels like a minute.
That's relativity"
Schrödinger disagrees.

Yes, well, he clearly spent too much time with cats and not enough time, relatively, with fit women sitting on his lap.

Why did Schrödinger's cat cross the road?
Both to get to the other side and not to get to the other side.

I don’t think Schrödinger jokes are funny anymore - but I still find them hilarious
I don't understand Einstein's theory of relativity. It's too much for my brain to comprehend. I just accept a journey at light speed crossing the cosmos that will take millions of earth years, will seem like a week and a half or so for those on board, but I couldn't explain why.
My point about the Voyagers is they are trapped in our galaxy and don't have the velocity to escape into the true void of space. They have travelled out of our solar system, but stll have the Orc cloud to negotiate, which is a ring of comets and rocks in orbit around our sun.
That will happen in about 30,000 years time, and after they emerge from that, they will finally be free from the garavitational pull of the sun, but will still be bound by the gravity of our galaxy.
To escape from our galaxy and become true nomadic wanderers of the cosmos, which is how I imagined them, they would need to be travelling at 1.2 million mph. As they are moving at a far slower speed than that, they will spend their days going round in circles taking 250 million years to complete each orbit.

Gazza - wrote. “When I left school I went for a interview for a job at Robertson's Jam in Droylsden in the labs doing the kind of thing you describe above - I was well in, with the interviewer really impressed until I mentioned that I was colourblind........ they couldn't get rid of me fast enough after that.”
.."…."………..
If my memory serves me correctly David Cross was, sometime in the dim and distant past, factory manager there. He moved down to the West Country in the mid 60’s after Robertson’s acquired Quantock preserves. Anyhow, one day in late spring I got a ‘phone from him. He had an insect on his desk and wanted to know whether he had a problem. It was still alive and he didn’t want to kill it to send it to me to identify (He was a nice man!). Anyhow got him to describe it to me asking questions whilst I started drawing a sketch of it. I soon recognised what it was from my sketch - it was a Cockchafer, and I was able to reassure him that he could release it outside as it wasn’t a recognised food pest.
However, it reminded me that as a student I spent a vacation working in the labs at another preserve works in Middleton. It was an old factory and had been condemned by the environmental health folk so was being closed down.
Early on in my time there I was given a factory tour, by a nice young lady from the lab, Ria Golucci (?) I think was her name. We came to a room where there were three steam jacketed pans. She told me that the two on the left could be used for Mayonaise or Brown Sauce whilst the one on the right could only be used for brown sauce. Naturally I asked why and was told “ Well, when we turn on the steam to that pan the ‘steam fly’ (Cockroaches) come out and we have to batter them with the wooden paddles!”.
Those were the days! As lab workers we could eat in the management dining room rather than the workers canteen, but still had to have our cards stamped as we clocked on and off.

They will see millions of flat earths in a universe that is just 6,000 years old.

I think that part is the unknown and probably a large drive behind voyager missions. It is the difference between Newton's apple on the head and Einstein's general theory of relativity combined with the special theory of relativity.
We will never be alive to know anyway, because if the theory is proven true then it will be so far in the future, our planet probably won't exist anymore, purely due to time passing here! What a headfuck!
