How the Universe Got Its Spots: Diary of a Finite Time in a Finite Space Janna Levin “The simpler the insight, the more profound the conclusion.” Is the universe infinite or finite? Mind-bending read from astrophysicist Janna Levin, who sets out to answer the question in letters to her mother:
Trying to explain the topology of the Universe is really complicated… for humans. But it clearly comes naturally to Zogg the Alien from Betelgeuse. In this 10-minute video, the plucky alien vividly describes how we could have a Universe which is flat and finite, but doesn’t have an edge. How we could travel in one direction and return to our starting point, never bumping into the outside of the Universe.
10 Ways the Universe Could End - Most physicists believe that the universe is infinite, but others believe it is finite and that could be a big problem. If the universe isn’t infinite, that means at some point the universe will start to retract, like waves rolling back into the ocean.

The Universe includes planets natural satellites minor planets stars galaxies the contents of intergalactic space the smallest subatomic particles and allmatter and energy. The observable universe is about 28 billion parsecs (91 billion light-years) in diameter at the present time. The size of the whole Universe is not known and may be either finite or infinite.Observations and the development…

Starts With A Bang #10: The Last Star In The Universe While there are presently more than ~10²³ stars in the Universe shining today, each one of them is fated to live only for a finite amount of time. While more and more will continue to form, we’re already past the point of peak star formation in the Universe. How long will we have until, for the last time, the Universe’s last star goes out?

The mass of the Higgs boson particle, possibly uncovered at the Large Hadron Collider (LHC) in Geneva, may mean doom for our universe. Here, proton-proton collisions at the LHC showing events consistent with the Higgs.
Madness and Genius: Cosmologist Janna Levin on the Vitalizing Power of Obsessiveness, from Newton to Einstein
"Light takes a finite amount of time to travel towards us, so when you look farther away, you actually see farther back in time," said Dunlop, an astronomer from the University of Edinburgh. "The faintest galaxy you can see here, you're actually looking back in time about 12-13 billion years. Which is about 90% of the age of the universe."
