How does Harry change? What happens to the monster? It's an amazing journey of science fiction and a lesson on sibling relationships. Nov 12, Virginia rated it it was ok Shelves: young-adult , read , speculative-fiction. Thank goodness the book picked up near the latter third. I really hated the main characters.
Truly, couldn't stand either Barry or Harry. Wanted to punch them in the face. Once it picked up though, after Harry's decisive action , it got more interesting. Well, I suppose only more interesting than the first half. But mostly, it reminded me that I couldn't wait for this book to end. View 1 comment. Nov 07, Kevin Anderson rated it really liked it. This book was super interesting. I read this probably 12 years ago, so my memory is fuzzy, but very positive. Nov 23, Sophie rated it really liked it Shelves: young-adult , fiction , science-fiction.
This book simultaneously frightened me and blew my mind when I was younger. To say why would spoil the ending. Shelves: sci-fi , fantasy-otherworldy , from-childhood , read-repeatedly , drama-bittersweet , children-modern. I first read Singularity as part of required reading in school. I immediately fell in love with it as it set my mind on fire with possibilities! I grew up as an only child and the mere thought of having a sibling was an unknown and amazing thing to me, then to think of what the twins relationship must have been like and for it to have been changed forever was simply unfathomable.
To have an event like this happen that was exciting, dangerous, and should have been forbidden, filled me with wonder I first read Singularity as part of required reading in school. To have an event like this happen that was exciting, dangerous, and should have been forbidden, filled me with wonder and gave me for the first time a sense of my own mortality.
I've read Singularity many times over the years, the very same edition that I got from school, and I will read it again! Nov 08, Lucas Mangum rated it really liked it Shelves: reads. This was a super-fun science fiction novel for young readers that I found entirely by accident when I was wandering my college library. There are some great ideas about the passage of time and other dimensions that I didn't even think were being talked about at the time of the book's writing.
Best of all, this is a coming-of-age story about a boy struggling to step out of the shadow of his only slightly older twin. Sep 18, Jay Gabler rated it it was amazing. A brilliant novel by an under-appreciated novelist, intelligent and melancholy. If you've never read it, read it. If you read it when you were younger, read it again and you may find that it resonates in a new way. I loved this book as a kid, and re-read it a bunch of times, so when it came across my desk when I worked for an Amazon marketplace seller a decade ago, I bought it instead of listing it.

It's a great introduction to some classic sci-fi themes for kids, while also including a lot of coming off age ideas without beating the reader over the head with them. May 07, Kipole rated it really liked it. Interesting science fiction tale dealing with issues of twin identity and how to adjust to it in an intriguing way. Harry's time of isolation also correlates with the creature coming through that all the characters have noticed and is an enjoyable read again and again. Sep 03, Jonathan K rated it really liked it.

Quick read. I remember this being a favorite when I was younger so I decided to see if I remembered it correctly. Great little sci-fi book dealing with special relativity, though it never says that outright. Character development is clunky but appropriate for a young adult book. Overall fun.

Singularity, by William Sleator is about two twins, named Harry and Barry, who travel alone to Sushan to watch over the house of their uncle who just passed away. There, after looking around, they discover a, "singularity" in a playhouse, where time moves faster in that certain space. In the playhouse, they find that a dangerous-looking creature is coming, but when Harry wanted to call the police, Barry threatens to lock himself inside to playhouse so that he could age a year over Harry and the Singularity, by William Sleator is about two twins, named Harry and Barry, who travel alone to Sushan to watch over the house of their uncle who just passed away.
In the playhouse, they find that a dangerous-looking creature is coming, but when Harry wanted to call the police, Barry threatens to lock himself inside to playhouse so that he could age a year over Harry and they wouldn't be twins anymore so Harry then decided to lock himself in the playhouse at night; and spent a year inside where he grows in age, physically, and mentally.
Once he gets out, he meets with Barry in the house, where Barry experienced many emotions there, including fear, grief, which was unexpected considering his old behavior for his new brother. In the end, the creature comes out and eats itself, or self destructed, and with all the sound and commotion the police came to make sure everyone was safe, and the brothers, no longer twins, returned home. This was the the first science fiction book that caught my eye because the title sounded interesting, and the cover picture looked cool. I'm glad I found this book, for I really enjoyed the plot, and it had many things about time, which I always fine exciting because it can be complex and lead to some really cool and interesting events.
I finished this book because I enjoyed the plot. Though it may have been slow at times, everything was necessary for me to understand everything deeply, to really be with the characters and experience their emotions. To really connect with the story.
The Quest for Singularity: The Twin Journey
I thought it was exciting the whole way through so I didn't put this book down until I was done. I would recommend this book to all readers who enjoy the science fiction genre. Though I do not read to much from this genre, I really liked this book, and with such a deep and interesting plot, I'm sure anyone would like this book.
Mainly though I think sci-fi readers would enjoy this the most as they are likely familiar with these types of texts. Final message, I really enjoyed this book, it's one if the best books I've read in a while. What I really like about it though, is that it had a lot to do with sibling relationships, Harry and his twin. I really connected to this, though I do not have a twin, I have a brother very close in age, and I could really relate with the characters and their relationship. Jan 10, Juan rated it really liked it. Upon arriving in town, Barry and Harry hear suspicious descriptions about their uncle: he only interacted with himself, he operated at oddly late hours of the night, and any creatures who stepped on his property aged significantly in a short period of time.
Looking in the backyard, they notice a small metal shed with no markings. What begins as a curious science experiment for the boys becomes an opportunity for Harry to level the playing field and be the dominant one for once in his life, and it brings Barry to tears. Sleator uses his framework of science fiction to add a new spin to sibling rivalry in a way the brothers will never forget. The science fiction elements are elaborated multiple times and have direct ties to thematic and character development.
Singularity would be best implemented in a seventh- or eighth-grade classroom due to higher-thinking level topics, and the length is short. Jul 09, Julie Decker rated it it was amazing. Harry's got a twin brother. And Barry has always been the dominant twin, which irritates Harry, but he can't seem to escape it. He wants to get along better with his brother, and hopes their summer vacation at their weird old uncle's old house will help, but Barry just continues to boss Harry around and complain about feeling burdened by him as they investigate a mystery surrounding a shed on the property.
Soon they discover that time moves faster in that room for some reason--entering the shed Harry's got a twin brother. Soon they discover that time moves faster in that room for some reason--entering the shed means you'll have a day pass by when someone else outside waits only seconds. As they begin to investigate what their weird uncle was doing in this place, the boys' rivalry escalates to a breaking point, and Harry decides to do something drastic--both for their investigative mission and for their relationship, to change it once and for all.
I didn't care so much about the "monster" plot or the investigation of the singularity; what absolutely ensnared me was the bittersweet feeling Harry had about his brother--both competitive and subservient at once, and how he eventually took refuge in the mysterious room as a way of buying some time to work on his self-improvement both physically and mentally.
The time he spent in that room, hyper-scheduled, content, rationed, intensely becoming a new person, was the highlight of this book. I loved his "Saturnalia" celebration and how he almost got arrested. So there's a very eighties young adult type of writing to this book, and the characters and plot aren't immediately interesting. That's kind of an expected thing in most William Sleator novels though. I had heard great things about Singularity, so I had my expectations uncomfortably high. I was getting ready for disappointment the more I read, because I really wasn't sure if it was going to pick up.
But So there's a very eighties young adult type of writing to this book, and the characters and plot aren't immediately interesting. But it DID. Harry is awesome. The book is awesome. I don't know what I can say about it without giving much away. No, it's not perfect. But it's meant to be a quick read, not an indepth hard scifi novel, so I can forgive Sleator for not fleshing out some of the stuff as much. But despite this, there's lots of technobabble to explain the singularity and time travel and stuff like that.
The LIGO project was begun back in , and the first iteration operated from to without a single gravitational wave detection. In , they started improving the facility, and in , Advanced LIGO came online with much more sensitivity. With the increased capabilities, Advanced LIGO made its first discovery in , and now two more discoveries have been added.
LIGO can currently only detect the general hemisphere of the sky where a gravitational wave was emitted. In addition to improving the sensitivity of LIGO, this will give astronomers three observations of each event, to precisely detect the origin of the gravitational waves. Then visual astronomers could do follow up observations, to map the event to anything in other wavelengths. A European experiment known as Virgo has been operating for a few years as well, agreeing to collaborate with the LIGO team if any detections are made.
It should be capable of detecting binary neutron star mergers out to nearly a billion light-years away. Just with visual astronomy, there are a set of next generation supergravitational wave telescopes in the works, which should come online in the next few decades. This will consist of a fleet of 3 spacecraft which will maintain a precise distance of 2. Compare that to the Earth-based detection distances, and you can see why the future of observations will come from space. And that last idea, looking right back to the beginning of time could be a possibility with the Big Bang Observer mission, which will have a fleet of 12 spacecraft flying in formation.
Gravitational wave astronomy is one of the most exciting fields of astronomy. This entirely new sense is pushing out our understanding of the cosmos in entirely new directions, allowing us to see regions we could never even imagine exploring before.

The discovery that the Universe has been expanding for billions of years is one of the biggest revelations in the history of science.
In a single moment, the entire Universe popped into existence, and has been expanding ever since. We know this because of multiple lines of evidence: the cosmic microwave background radiation, the ratio of elements in the Universe, etc.
The Quest for Singularity : The Twin Journey
But the most compelling one is just the simple fact that everything is expanding away from everything else. Which means, that if you run the clock backwards, the Universe was once an extremely hot dense region. The closer you get to the Big Bang, the closer everything was, and the hotter it was. When you reach about , years after the Big Bang, the entire Universe was so hot that all matter was ionized, with atomic nuclei and electrons buzzing around each other.
Keep going backwards, and the entire Universe was the temperature and density of a star, which fused together the primordial helium and other elements that we see to this day. Further back still and even atoms break apart into quarks. An infinitely dense Universe cosmologists called the singularity. When you look out into the Universe in all directions, you see the cosmic microwave background radiation. And the temperature of this radiation is almost exactly the same in all directions that you look.
There are tiny tiny variations, detectable only by the most sensitive instruments. When two things are the same temperature, like a spoon in your coffee, it means that those two things have had an opportunity to interact. The coffee transferred heat to the spoon, and now their temperatures have equalized. When we see this in opposite sides of the Universe, that means that at some point, in the ancient past, those two regions were touching. That spot where the light left For the Universe to have the uniform temperature we see today, it would have needed to spend enough time mixing together.
Imagine you dipped that spoon into the coffee and then pulled it out moments later before the heat could transfer, and yet the coffee and spoon are exactly the same temperature. To address this problem, the cosmologist Alan Guth proposed the idea of cosmic inflation in That moments after the Big Bang, the entire Universe expanded dramatically. Before inflation, the observable Universe was smaller than an atom.
After inflation, it was about 0. Today, those regions have been stretched 93 billion light-years apart. This concept of inflation was further developed by cosmologists Andrei Linde, Paul Steinhardt, Andy Albrecht and others. The first is known as the flatness problem. The most sensitive satellites we have today measure the Universe as flat.
Not like a piece-of-paper-flat, but flat in the sense that parallel lines will remain parallel forever as they travel through the Universe. Under the original Big Bang cosmology, you would expect the curvature of the Universe to grow with time. The second is the horizon problem. The third is the monopole problem. Although the cosmic microwave background radiation appears mostly even across the sky, there could still be evidence of that inflationary period baked into it.
In order to do this, astronomers have been focusing on searching for primordial gravitational waves. These are different from the gravitational waves generated through the collision of massive objects. Primordial gravitational waves are the echoes from that inflationary period which should be theoretically detectable through the polarization, or orientation, of light in the cosmic microwave background radiation. A collaboration of scientists used an instrument known as the Background Imaging of Cosmic Extragalactic Polarization or BICEP2 to search for this polarization, and in , they announced that maybe, just maybe, they had detected it, proving the theory of cosmic inflation was correct.
Unfortunately, another team working with the space-based Planck telescope posted evidence that the fluctuations they saw could be fully explained by intervening dust in the Milky Way. In order to really get to the bottom of this question, more searches need to be done, scanning a series of overlapping frequencies. BICEP2 and Planck and the newly developed South Pole Telescope as well as some observatories in Chile are all scanning the skies at different frequencies at the same time.
Distortion from various types of foreground objects, like dust or radiation should be brighter or dimmer in the different frequencies, while the light from the cosmic microwave background radiation should remain constant throughout. There are more telescopes, searching more wavelengths of light, searching more of the sky. We could know the answer to this question with more certainty shortly. One of the most interesting implications of cosmic inflation, if proven, is that our Universe is actually just one in a vast multiverse.
While the Universe was undergoing that dramatic expansion, it could have created bubbles of spacetime that spawned other universes, with different laws of physics. The Big Bang was one of the greatest theories in the history of science. Although it did have a few problems, cosmic inflation was developed to address them. Although there have been a few false starts, astronomers are now performing a sensitive enough search that they might find evidence of this amazing inflationary period.
Paul Matt Sutter — why do we call the Big Bang a singularity, when we also call black holes singularities? Podcast audio : Download Duration: — 4. How was our Universe created? How did it come to be the seemingly infinite place we know of today? And what will become of it, ages from now?
These are the questions that have been puzzling philosophers and scholars since the beginning the time, and led to some pretty wild and interesting theories. Today, the consensus among scientists, astronomers and cosmologists is that the Universe as we know it was created in a massive explosion that not only created the majority of matter, but the physical laws that govern our ever-expanding cosmos. This is known as The Big Bang Theory. For almost a century, the term has been bandied about by scholars and non-scholars alike.
This should come as no surprise, seeing as how it is the most accepted theory of our origins. But what exactly does it mean? How was our Universe conceived in a massive explosion, what proof is there of this, and what does the theory say about the long-term projections for our Universe? In science fiction, wormholes are a method often used to travel great distances across space. Are these magic bridges really possible? Reality tells us that even the most nearby stars are incomprehensibly far away, and would require vast amounts of energy or time to make the journey. Science fiction, on the other hand, woos us with its beguiling methods of advanced propulsion.
Crank up the warp drive and watch the stars streak past us, making a journey to Alpha Centauri as quick as a pleasure cruise. A wormhole; a magical gateway that connects two points in space and time with one another. Just align the chevrons to dial in your destination, wait for the stargate to stabilize and then just walk… walk! Yeah, that would be really nice. Someone should really get around to inventing these wormholes, ushering in a bold new future of intergalactic speedwalking.
What are wormholes, exactly, and how soon until I get to use one?. A wormhole, also known as an Einstein-Rosen bridge is a theoretical method of folding space and time so that you could connect two places in space together. You could then travel instantaneously from one place to another. That works great on paper, but is this actual physics?
