There is a Welsh speaking community in Patagonia. Not sure what the speed limit is...:)

Been a few documentaries about the Patagonia Welsh. Welsh teashops in the Chubut Valley and towns with names like Trelew. Think there's still an Eisteddfod there too.

There was a claim that at one point when the Welsh language was most on its uppers there were more Welsh speakers left in Patagonia than Wales but not sure if that's true. Either way the two communities of speakers have had a beneficial effect on each other. I think it's great.

So we’re not going to see it in our lifetime as I’d say it would have been detected by Hubble or JWST before now.

Saw a really interesting program by Brian Cox yesterday, where he discussed the possibilities of time travel.
He didn’t rule anything out per se, but basically we can and do see the past all the time, because of the length of time it takes for light to travel to your eye and the impulses interpreted by your brain.
Time is reletaive as Einstein proved. And if we see space time as in 3-D we are always moving forward so actually going back in space time is impossible.

Why? Does the light travel faster towards telescopes?

During The Dam Busters raid in 1943, pilots were required to fly at 60 feet in order to execute the mission, but during the making of the 1956 film, the director thought it looked too high so asked the pilots to fly at 30 feet in order to create the effect of low flying.

Telescopes can see further away than our eyes can. But, in space terms, the further away something is, the further into the past it is because of how long it takes the light from the object to reach us.

This is something which baffles me.
I understand that the further away an object is, the longer the light from that object takes to reach us.
But surely some of those objects would be ahead of us?
If we observe an object we say that it is x light years from us, in the past.
If some advanced life exists on one of those objects and they are observing us simultaneously, how can we be x light years in their past also?
Perhaps an egghead could provide the answer?

But, if the object is the same distance away, why would a telescope 'see' it first?

Edit: We're talking about a star we can see with our naked eyes

Spirits in public houses are ridiculously overpriced! A one litre bottle providing forty measures at an average price of £240. Cost to trade for one litre bottle being circa £12, and they little wonder why their all on their arse.

Overheads not included but do the maths. Your far better off supping on the Moon and solving riddles!

I think that all the stars we see are in the past so if anyone on those stars were looking at us all the stars would be in there past so they can’t see us.
I just made that up because I’m guessing I’d love to know and I’m sure someone on here knows the answer

I can't say "Shropshire" without whistling. Not very interesting but I've just found it out.

What tune do you whistle?

If the earth and the moon have a gravitational effect on one another how come when astronauts travel out of the earth's atmosphere they become weightless?
