A teacher once told me that our galaxy is on course to collide with the Andromeda galaxy in the next few million years. He said that it wouldn't do much except allow us to travel into the other Galaxy. Is this true?
We will be colliding with Andromeda, in about 4 billion years. Andromeda has 14 small galaxy companions, which Andromeda will likely interact with and accrete a lot of their matter prior to then. The Milky Was also has satellite galaxies that we will interact with – we are currently swallowing the Sagittarius Dwarf Spheroidal Galaxy, which we will pass through in about 100 million years.
Galaxy interactions lead to galaxy evolution. Andromeda and the Milky Way are both fairly massive galaxies, and their interaction will result in a giant elliptical galaxy or one disk galaxy (probably, elliptical)
Here’s a simulation showing how it might go down:
I wouldn’t say “it wouldn’t do much except allow us to travel into the other galaxy,” galaxy interactions can lead to star-formation bursts (although, by this time each galaxy may not have enough gas left to form new stars). But, the collision is an interesting step in our galaxy’s evolution!
It won’t affect life in our solar system very much other than a change in orbit around the galactic center.
However, the view is expected to be great! (Via NASA; ESA; Z. Levay and R. van der Marel, STScI; T. Hallas, and A. Mellinger)
Solar eclipse of 2010 - This was with 11 minutes and 41 seconds the longest annular solar eclipse in 1000 years. It was seen as an annular eclipse across Central Africa, India, Sri Lanka and China.

Should it be worrying if I’ve seen all those tints in water samples from last three months?

Good to know that for once I did something well enough. Sometimes. Perhaps. *Coughs into a fist*
How to praise writers and influence fics
I’ve seen a lot of posts recently reminding readers to leave feedback on fics, which is great!! Writers deserve all the love they can get. Likes, reblogs, comments, messages, these are the lifeblood of writers. They are proof that people are reading, that they’re enjoying, and that they want more.
But maybe readers don’t know what to say. Maybe you’re new to Tumblr, new to reading fan fiction, shy, or just not sure how to say what you want to say.
Let me start by saying, no matter how popular the blog or how cool you think they are, everyone loves a compliment. If you’re worried about sounding silly or bothering people, let me assure you- a message will make your writer do a happy dance (depending on the writer, they may actually get up and dance. I have.)
Here’s the basic ways of communicating with writers on Tumblr:
Likes and kudos- these are great, they’re the high-fives in this world. They’re the “hey, nice” nod. Reblogs- even better, because they mean exposure. More people see the story and that makes us really happy. A reblog with a comment is amazing, especially one that entices others to read. These make a writer’s day. Comments and messages- these are the thing that keeps us going. Most of us have anon turned on- and if we don’t, just let us know you want a private reply. (And, if your writer has anon off, it probably means they’ve been getting hate and deserve extra love.) Recommendations- recs are like coming in to work to find someone baked your favorite cake and left it on your desk. Recommendations make your writer feel so loved and valued!
So, that’s all good, but what do you actually SAY to writers? It doesn’t have to be much or take a lot of time.
A simple “This is great/funny/hot!” is wonderful. "Best fic I’ve read this week!“ "Funny as hell and cute too.” "You have to read this, it’s awesome!“ "I can’t wait for more of this.” "I hope you keep going!“ These are great in reblogs and in messages.
Even better is specific feedback. We love specific feedback, because it tells us what readers liked and what they didn’t. Want to influence our next fic? Tell us what you liked about this one and I bet you it will keep showing up! Specific feedback is just telling the writer what you liked. It doesn’t have to be long or complicated, either. (But if you write a lot, we will love you so much.)
Was there a character you liked? Talk about them: "I love how you wrote X” “Y was so funny!” "OMG I wanted to STRANGLE Q!“ "You can really feel X’s frustration.” "Y has so much depth, they’re a really well-rounded character.“ "R says so much with so few words, it’s amazing.”
What about a part or line you enjoyed? "That bit in the park- LOVE IT.“ "I have never read a better description of a cup of tea.” "The way you wrote about his fear, that was heartbreaking.“
Was there a part that made you feel something? Happy, sad, angry? "That last sentence killed me, he’s so broken.” "I wanted to jump around when they finally kissed!“ "This chapter was so tense, my heart was pounding by the end.”
Did the characters or plot or setting remind you of your life? "I live in Brussels, that’s just how that street looks.“ "When Y talked about R, I knew exactly how he felt.” "You captured that lost, aimless feeling perfectly; I’ve so been there.“
Are there unanswered questions? Mention how much you want the answers. "I can’t wait to find out what’s in the basket!” "That was a cliffhanger ending, wow.“ "How is she going to explain THAT?” (some writers are touchy about predicting, though, so stay away from “I bet he’ll throw that letter out.” or “X is clearly coming back.”)
A few closing notes: be enthusiastic if that’s your style, go crazy with exclamation marks, smileys, caps! Tell a writer if you’re rereading their work- very little makes us happier than knowing our writing has the staying power for a second, third, sixth, tenth read. Did a reread give you a new insight or feeling about the fic? Tell us! We will be so excited to hear. And remember, recommendations are wonderful- putting up a random post tagging your favorite writers or fics you’re enjoying will show the writers that they’re writing is more than a flash in the opan and they’ll get some new readers too!
We can’t do this writing thing without you guys. So thank you so much! Without readers, we’re just talking to ourselves. We love and appreciate you for reading- but we need to know you’re doing it. We need feedback like we need air. Don’t let your favorite writers suffocate! :)
Look who stole a night from me again. I’m still too damn enamored with Gorilla’s Solas for my own sanity and well-being.
Happy Friday!
Thank you all for being so great and sending me so much love this past week! Everything is much more manageable now.
Hopefully, you all had a great week! <3 <3
I hope that you enjoy the first date!!!

There is nothing to add, it just deserves reblogging. I can’t even begin to explain why it turns me on so much.
What are Gravitational Waves?
Today, the National Science Foundation (NSF) announced the detection of gravitational waves by the Laser Interferometer Gravitational-Wave Observatory (LIGO), a pair of ground-based observatories. But…what are gravitational waves? Let us explain:
Gravitational waves are disturbances in space-time, the very fabric of the universe, that travel at the speed of light. The waves are emitted by any mass that is changing speed or direction. The simplest example is a binary system, where a pair of stars or compact objects (like black holes) orbit their common center of mass.
We can think of gravitational effects as curvatures in space-time. Earth’s gravity is constant and produces a static curve in space-time. A gravitational wave is a curvature that moves through space-time much like a water wave moves across the surface of a lake. It is generated only when masses are speeding up, slowing down or changing direction.
Did you know Earth also gives off gravitational waves? Earth orbits the sun, which means its direction is always changing, so it does generate gravitational waves, although extremely weak and faint.
What do we learn from these waves?
Observing gravitational waves would be a huge step forward in our understanding of the evolution of the universe, and how large-scale structures, like galaxies and galaxy clusters, are formed.
Gravitational waves can travel across the universe without being impeded by intervening dust and gas. These waves could also provide information about massive objects, such as black holes, that do not themselves emit light and would be undetectable with traditional telescopes.
Just as we need both ground-based and space-based optical telescopes, we need both kinds of gravitational wave observatories to study different wavelengths. Each type complements the other.
Ground-based: For optical telescopes, Earth’s atmosphere prevents some wavelengths from reaching the ground and distorts the light that does.
Space-based: Telescopes in space have a clear, steady view. That said, telescopes on the ground can be much larger than anything ever launched into space, so they can capture more light from faint objects.
How does this relate to Einstein’s theory of relativity?
The direct detection of gravitational waves is the last major prediction of Einstein’s theory to be proven. Direct detection of these waves will allow scientists to test specific predictions of the theory under conditions that have not been observed to date, such as in very strong gravitational fields.
In everyday language, “theory” means something different than it does to scientists. For scientists, the word refers to a system of ideas that explains observations and experimental results through independent general principles. Isaac Newton’s theory of gravity has limitations we can measure by, say, long-term observations of the motion of the planet Mercury. Einstein’s relativity theory explains these and other measurements. We recognize that Newton’s theory is incomplete when we make sufficiently sensitive measurements. This is likely also true for relativity, and gravitational waves may help us understand where it becomes incomplete.
