CAN HUMANS TRAVEL BEYOND OUR SOLAR SYSTEM??

Blog#479

Wednesday, February 12th, 2025.

Welcome back,

Interstellar space travel. Fantasy of every five-year-old kid within us. Staple of science fiction serials. Boldly going where nobody has gone before in a really fantastic way. As we grow ever more advanced with our rockets and space probes, the question arises: could we ever hope to colonize the stars? Or, barring that far-flung dream, can we at least send space probes to alien planets, letting them tell us what they see?

The truth is that interstellar travel and exploration is technically possible. There's no law of physics that outright forbids it. But that doesn't necessarily make it easy, and it certainly doesn't mean we'll achieve it in our lifetimes, let alone this century. Interstellar space travel is a real pain in the neck.

If you're sufficiently patient, then we've already achieved interstellar exploration status. We have several spacecraft on escape trajectories, meaning they're leaving the solar system and they are never coming back. NASA's Pioneer missions, the Voyager missions, and most recently New Horizons have all started their long outward journeys. The Voyagers especially are now considered outside the solar system, as defined as the region where the solar wind emanating from the sun gives way to general galactic background particles and dust.

So, great; we have interstellar space probes currently in operation. Except the problem is that they're going nowhere really fast. Each one of these intrepid interstellar explorers is traveling at tens of thousands of miles per hour, which sounds pretty fast. They're not headed in the direction of any particular star, because their missions were designed to explore planets inside the solar system. But if any of these spacecraft were headed to our nearest neighbor, Proxima Centauri, just barely 4 light-years away, they would reach it in about 80,000 years.

I don't know about you, but I don't think NASA budgets for those kinds of timelines. Also, by the time these probes reach anywhere halfway interesting, their nuclear batteries will be long dead, and just be useless hunks of metal hurtling through the void. Which is a sort of success, if you think about it: It's not like our ancestors were able to accomplish such feats as tossing random junk between the stars, but it's probably also not exactly what you imagined interstellar space travel to be like.

Maybe in a different universe, we’ll be together.

And they were.

The cheerful and selfless dark-haired sweethearts and their confident and endearing golden haired lovers.

In a parallel universe, they'd be besties. 🥹

Cale needed that evil god's test. Not only to fight despair, but also for his mental health.

He needed to see that there was a world where "Kim Rok Soo" was not left to survive alone. He needed to see all his "what ifs" happen. He needed to resolve all the regrets of "Kim Rok Soo" to fully live as Cale Henituse. Because even if it wasn't his world, he now knows that a "Kim Rok Soo" was happy, surrounded by people he loves, people who would survive with him.

That is how he can loosen the shackles of fear of being alone again as Cale. "We will all survive" is not just a random mantra for him. He needs it to be true. He has had so much loss and grief in his life.

Even if he doesn't really say so, that grief was what kept him going. To "not waste" the sacrifices of all those who saved him, he kept surviving. But that is also why he's reckless despite "valuing" his life.

I think, subconsciously, he thinks that if he can save more people, then that would be a good "payment" for those who saved him. His "slacker life" is basically world peace. 🤭

Back to the point... The test showed him Kim Rok Soo and everyone he cares for survive, so now he has more courage and less doubt to face WS because he wants a life like Parallel KRS', as Cale Henituse.

HOW ARE BLACK HOLES CREATED, AND HOW DO THEY GROW??

Blog#461

Wednesday, December 11th, 2024

Welcome back,

In 2017, astronomers started finding monster black holes in the very early universe. Containing roughly a billion times the mass of our Sun, these black holes were surrounded by disks of infalling matter shining so intensely that we can detect them across immense stretches of space and time.

These gravitational giants existed when the universe was only 700 million years old, or 5 percent its current age. At that point in cosmic history, the universe was still a toddler. Gravity was just beginning to rein in clouds of gas and dark matter to form structures that would later evolve into mature spiral and elliptical galaxies. Stars were beginning to pop into being, but they do today.

According to the traditional picture of black hole formation and growth, the universe at this time simply had not existed long enough for black holes to bulk up to a billion solar masses.

So, based on our general understanding of how black holes form and grow, these black holes should not exist.

And yet they do — posing a major challenge that astrophysicists have yet to unravel.

Quasars are brightly shining beacons of light and energy generated by the accretion of material onto supermassive black holes. In the 1990s, astronomers using a combination of ground- and space-based telescopes started to find extremely distant quasars powered by black holes of a billion or more solar masses.

By the mid-2010s, it was no longer a big deal to find quasars dating back to 1 billion or 2 billion years after the Big Bang. But theorists had a difficult time explaining how such massive black holes could have arisen so soon in the universe’s history.

For quasars and other objects that existed many billions of years ago, it’s meaningless to express their distances in terms of light-years. The universe has expanded so much between then and now that astronomers instead refer to an object’s redshift, which is a measurement of how much cosmic expansion has stretched the object’s light toward redder (longer) wavelengths.

For years, astronomers such as the University of Arizona’s Xiaohui Fan have been identifying quasars at redshifts as high as 6, when the universe was about 900 million years old. They’ve even found a few around redshift 7, which corresponds to an era when the universe was about 735 million years old. But in late 2017, an international team led by Eduardo Bañados of the Carnegie Institution for Science announced a quasar at a record-shattering redshift of 7.54. This quasar, designated J1342+0928 (J1342 for short), based on its sky coordinates in Boötes, was radiating 40 trillion Suns’ worth of energy at a time when the universe was only 690 million years old.

The team found J1342 by mining data from NASA’s Wide-field Infrared Survey Explorer satellite, the United Kingdom Infrared Telescope Deep Sky Survey Large Area Survey, and the DECam Legacy Survey. They used the 6.5-meter Magellan Telescope in Chile to measure the quasar’s redshift, while observations with the 8-meter Gemini North Telescope in Hawaii enabled the team to estimate the black hole’s mass: around 800 million Suns.

Lost Fic - Found

sterek fic where in a parallel universe stiles and derek are together and accidentally they hop into another universe where they weren't together and eventually other stiles and derek get together in that universe too and the first pair goes back to their own reality.

@suze-is-amused found this one!

Where The Inevitable Isn't by Survivah

(6/6 I 41,260 I Mature I Sterek)

Stiles has a magical thingamajig that's supposed to get him out of danger. Trouble is, it took him really, really far out of danger. Like, to the point where he isn't in the same universe anymore.

"A part of Stiles had been thinking that he’d come home, and just go, 'hey, Derek, are we mates and you just haven’t said anything about it?' and Derek would reply, 'now you mention it, we are indeed! Now come to my bedchamber, where we will have super hot sex and then cuddle after!'"
