Lifeboat Foundation

Ironically, my more popular posts are ones furthest from my passion and core interests. They are larks—never intended to go viral. This is about one of them…

Apart from family, I typically steer clear of religious topics. I identify with a mainstream religion, but it is completely beside the purpose of Lifeboat Foundation, and it is a personal affair.^[1]

Yet, here we discuss a religious topic, after all. Let’s get started…

Posthumous journal.

Groundbreaking physicist Stephen Hawking left us one last shimmering piece of brilliance before he died: his final paper, detailing his last theory on the origin of the Universe, co-authored with Thomas Hertog from KU Leuven.

The paper, published today in the Journal of High Energy Physics, puts forward that the Universe is far less complex than current multiverse theories suggest.

Looking deep into the observable Universe – and hence, back to the earliest periods of time – is an immensely fascinating thing. In so doing, astronomers are able to see the earliest galaxies in the Universe and learn more about how they evolved over time. From this, they are not only able to see how large-scale structures (like galaxies and galaxy clusters) formed, but also the role played by dark matter.

Most recently, an international team of scientists used the Atacama Large Millimeter-submillimeter Array (ALMA) to observe the Universe when it was just 1.4 billion years old. What they observed was a “protocluster”, a series of 14 galaxies located 12.4 billion light-years away that were about to merge. This would result in the formation of a massive galaxy cluster, one of the largest objects in the known Universe.

The study which described their findings, titled “A massive core for a cluster of galaxies at a redshift of 4.3”, recently appeared in the journal Nature. The study was led by Tim Miller – an astronomer from Dalhousie University, Halifax, and Yale University – and included members from NASA’s Jet Propulsion Laboratory, the European Southern Observatory (ESO), Canada’s National Research Council, the Harvard-Smithsonian Center for Astrophysics, the National Radio Astronomy Observatory, and multiple universities and research institutions.

If you’re the type of person who sometimes wakes up at 3am and lies in bed trying to wrap your tiny mind around the achingly vast Universe and where it’s all headed, well, we have something for you (also, same).

This incredible (and incredibly long) infographic from 2015 just keeps going and going and going. Which makes sense, because we’re talking about the entire lifespan of the Universe, from the moment of the Big Bang to the ‘heat death’ of everything we know and love.

Created by Slovak graphic designer Martin Vargic, the Timeline of the Universe covers the past 13.8 billion years of space, and then plots out what’s likely to occur in the next 10 billion or so.

Last year Kollmeier was named director of the fifth version of the Sloan Digital Sky Survey, a project that aims to map the universe. The survey, which launches in 2020, will employ telescopes in the Northern and Southern Hemispheres to scan the entire sky. The telescopes will obtain spectra of bright objects in the sky, breaking up that light into component parts. “That’s where the astrophysics is,” says Kollmeier. “That tells you all the chemical abundances. That tells you all the transitions in the objects.” And that’s where she’ll begin to find answers to her questions: How do supermassive black holes grow? Can stars be used as clocks that tell us when and how a galaxy was formed?

Kollmeier didn’t get into astronomy by looking up at the stars. She meant to be a lawyer until she went to what she calls “nerd camp” and learned how to write code to classify stars. “The idea that you could interrogate the universe in this way … I felt like an explorer.” Now she’s going further than she once thought possible.

If there is a phenomenon out there that is actually more bizarre than black holes, it has to be white holes. Black holes can’t say that they might be the answer to where so much of the dark matter—and even most of the matter—in the universe is lurking.

The gravitational pull of a black hole is so insanely strong that not even light (so much for being the fastest entity in the cosmos), can defy it. Nothing can save you once you pass the grim point of no return otherwise known as the event horizon. However, Space.com observed that when Einstein predicted the existence of black holes in his theory of relativity, he also predicted the theoretical reverse of these galactic monsters. A white hole would be no threat to objects in space passing dangerously close, nothing can even enter its event horizon.

When black holes devour massive amounts of matter and energy, it is thought that everything which appears to vanish forever actually emerges from a white hole. Exactly where the victims of a black hole come out could be anywhere from another place in this universe to another universe entirely. Theoretical physicist Carlo Rovelli theorized something even stranger linking the two. Black holes result from collapsed stars, but when these astral corpses die, they may actually turn into white holes.

With the recent launch of the Transiting Exoplanet Survey Satellite (TESS) – which took place on Wednesday, April 18th, 2018 – a lot of attention has been focused on the next-generation space telescopes that will be taking to space in the coming years. These include not only the James Webb Space Telescope, which is currently scheduled for launch in 2020, but some other advanced spacecraft that will be deployed by the 2030s.

Such was the subject of the recent 2020 Decadal Survey for Astrophysics, which included four flagship mission concepts that are currently being studied. When these missions take to space, they will pick up where missions like Hubble, Kepler, Spitzer and Chandra left off, but will have greater sensitivity and capability. As such, they are expected to reveal a great deal more about our Universe and the secrets it holds.

As expected, the mission concepts submitted to the 2020 Decadal Survey cover a wide range of scientific goals – from observing distant black holes and the early Universe to investigating exoplanets around nearby stars and studying the bodies of the Solar System. These ideas were thoroughly vetted by the scientific community, and four have been selected as being worthy of pursuit.

Dark energy means that the Universe’s expansion is accelerating. But how big will it get, and how fast?

Peering billions of light-years back to when the Universe was just 10 percent of its current age, astronomers have spotted a colossal pile-up: 14 young, starbursting galaxies merging into one of the most massive structures in the Universe.

Using some of the most powerful telescopes in operation today, an international research team discovered the extremely dense concentration of hot galaxies careening towards each other.

Eventually the megamerger will form a cluster of galaxies, gravitationally bound by dark matter and ultimately smooshing together into one ginormous galaxy.
