where is the end of the universe ? it has to end right?
Right by that restaurant.
By the time you find it - it will have moved again - so, no - not really.
I seem to remember the word infinity tossed around a bit during size of universe discussions.
The universe might be finite – must be, if physicists think they can estimate its total mass – but, the surface of a sphere is finite; that doesn’t mean you’ll ever find the edge.
14 billion years ago is one end. Now is the other.
I’m not pleased with the political impasse in Washington either, but I’m not that pessimistic.
Actually, what scientists are usually trying to estimate is its density, not its mass.
I know I have said this before. Some scientist said the universe is expanding at
5 to 55 times the speed of light. Even if the expansion is “only” light speed, you
can never catch up to the “cutting edge” of the universe. So there is no “where”
for you to nail down.
My somewhat limited understanding is that the universe will end in either the Big Rip (where the repellant forces driving the universe apart faster and faster will eventually do the same to all matter, ending up with even the atoms flying apart) or in a Big Crunch (where eventually all matter in the universe compacts back together). Either way (and I think the Big Rip theory is currently the more popular since by observation it’s clear that the expansion of the universe is actually accelerating, not slowing down) we are talking about literally trillions of years in the future (for reference, the universe is only around 14 billion and change today, so you are looking at 2 orders of magnitude difference at the minimum), so no need to worry about it quite yet. 
BUt that end was the ‘end’ of the universe - not the ‘end’
(location vs time)
anyway -
Which scientist said this?
I don’t know about now, but I seem to recall that in the early universe space expanded at many times the speed of light. I don’t know how ‘scientists’ could or would measure the current rate of expansion, but the various galaxies are moving away from each other at less than the speed of light but will one day (a few hundred billion years from now I suppose) be invisible to our galaxy and vice versa.
ETA: This guy says it might be.
No, it wasn’t – the universe itself ends and a messiah appears.
Shouldn’t that be the other way around-otherwise, where would he appear?
Good thing the judge changed his name last week or we’d all be done for.
It was just his cat.
I may be confusing the radio show with the books or TV series or movie, but I thought I remembered a messiah showing up right before the universe ends. Anyway, it definitely wasn’t then end-as-in-location, since it turned out they were still on Magrathea, right? That’s how they found Marvin again:
“The first ten million years were the worst," said Marvin, "and the second ten million years, they were the worst too. The third ten million years I didn’t enjoy at all. After that I went into a bit of a decline.”
Anyway, Czarcasm is right in that the messiah appears and then the universe ends.
So, is this thread headed to the Cafe?
It’s not meaningful to speak of the Universe expanding at some multiple of light speed: The units are wrong. It’d be like if I asked how far away someone lived, and you said “55 MPH”, or “200 pounds”. The proper units for measuring the expansion rate of the Universe would be units of frequency.
XT, the simplest model consistent with the evidence we have is that the Universe will have neither a Rip nor a Crunch, but just a whimper: Atoms (and planets, stars, and galaxies) will stay intact, but everything will just get cooler and cooler, and the available energy more and more dilute, until everything interesting just sort of fades away. That said, there’s enough we don’t know about the Dark Energy that a Rip or a Crunch is either one plausible (the former a bit more so than the latter).
Opinions vary. Some say Plains, Texas. Others feel it’s Poipet, Cambodia.
