but hole


Scientists just spotted 2 black holes flirting and dancing like awkward middle schoolers 

  • Astronomers have detected a pair of supermassive black holes 750 million light-years away from Earth in a separate giant galaxy.
  • Courtesy of the National Science Foundation’s Very Long Baseline Array’s (VLBA) radio vision data on the orbital motion of the black holes has been captured.
  • Together, the two black holes have a combined mass that is 15 billion times the mass of the Sun, which is 1.989 x 10^30 kilograms or 330,000 times the mass of Earth.
  • But most galaxies have supermassive black holes that are millions or billions times larger than the Sun at their core.
  • What makes these two black holes unique is their distance from one another: They’re relatively close to each other with only 24 light-years of distance between them. Read more (6/28/17)

Things that still don't make sense

- The Board Game meant literally nothing
- The secret underground passage wasn’t used to kill Charlotte
- How Mona got Mary and Alex to another country
- Bethany Young
- The first 6 seasons
- Why Wren introduced Alex to CeCe and not Spencer
- Why Wren DIED
- Spoby
- Why there was a need for that final scene
- Addison
- Why Lucas was tap dancing
- Blind girl on a horse. Smart
- Jenna having no part in the final twist
- Everyone just wanting CeCes money
- Sara Harvey
- Wren visiting Mona… flashback? Confused
- Mona’s dollhouse. Did she help CeCe with the S5 Dollhouse? “Tea Time”
- Sidney Driscoll
- Melissa’s existence in the finale
- Jason DiLaurentis’ non existence in the finale
- Jason not knowing he has 4 sisters now. Out of those one dead and one missing & a sociopath.
- Why Ezra was kidnapped? If Alex loved Aria that much why try to ruin her wedding day?
- Why CeCe loved Alex but only seen Spencer as her “doll”
- Why CeCe loved Alison and not Spencer



How Uncertain Are LIGO’s First Gravitational Wave Detections?

“What’s vital to understand is that no one is claiming LIGO is wrong, but rather that one team is claiming that perhaps LIGO has room for improvement in their analysis. And this is a very real danger that has plagued experimental physicists and astronomical observers for as long as those scientific fields have existed. The issue is not that LIGO’s results are in doubt, but rather that LIGO’s analysis may be imperfect.”

Three times now, the LIGO collaboration has produced very strong evidence that black hole pairs, from across the Universe, inspiraled and merged, producing gravitational waves. The twin LIGO detectors in Hanford, WA and Livingston, LA each detected these signals, and the signals were correlated between both detectors. For the first time ever (and the second, and the third), we had directly detected gravitational waves. But last month, a team of independent scientists from Denmark attempted to reproduce LIGO’s analysis, and noticed something that shouldn’t be there: noise correlations between the two detectors. Noise is supposed to be uncorrelated, and yet the noise correlations peaked at the moment of the inspiral-and-merger event. It doesn’t mean that gravitational waves aren’t real, but it does mean that LIGO, perhaps, has room for improvement.

This has been a very controversial topic over the past few weeks; come learn where we are in this saga of science playing out in real-time!

46 Questions "Pretty Little Liars" Never Really Answered

Well they actually did answer most of these!

1. Alex wanted to know who killed Charlotte and she wanted revenge. Since the girls were tortured by Charlotte and are always involved in crimes of course she thought they knew what happened and made the game to get answers

2. We know the liars aren’t that smart

3. Sense of smell I guess? It’s really not that crazy

4. Because they were both out for revenge because they believed they got a raw deal out of life, not that crazy or unbelievable as a motive

5. She’s MONA 

6. She was dating the cop that arrested them 

7. So crazy! It’s not like wren has ever cheated on anyone before!!

8. It happened before why couldn’t it happen again? Charlotte probably knew a guy

9. Maybe it was her favourite? Toby would know that       

10. Okay this one people can complain about. I guess Alex knew how valuable Mona was and if she kept the twincer secret she could live. Wren was sent to kill her and she must have manipulated him into letting them know that she is more valuable alive 

11. Idk he got a loan? Do we really care?  

12. They made fun of it in the show so I’m over it                                               

13. THIS. this is a plot hole to complain about. Too bad its hidden under irrelevant things we already know                                                                               

14. This I am confused about, I thought we all knew it was Wilden and that’s why he got so mad at Hanna, then the whole car thing happened                      

15. Paige? Wasn’t this around the time Cece said Ali was scared of her and all that? if not okay it is another plot hole.                                                               

16. I have no idea okay this is another one                                                         

17. He had just tried to kill his finance’s sister, and the person who pushed him off the bell tower could back her up. Is that not enough of a reason?               

18-19. I don’t remember specific details about the Bethany storyline so I’ll assume they are plot holes.                           

20. We know we has a bad dude, he was in the dollhouse for fun? AD got Sydney to do shady shit so AD probably had something on Noel too  

21. Wasn’t she about to tell Emily what was happening?

22. The treasure? that was bull shit so this one just sucks we don’t have a good reason                                                                                                                  

23. she’s too irrelevant to care 

24. Because she wasn’t visiting Mona as Charlotte. She was visiting her as Cece. Mona didn’t know who she was working for remember?  

25. We know Radley did not have the best security. Mona got out all the time 

26. Because I am sure Jason told his mom everything about his life

27. A red hearing red coat? idk pll does that all the time     

28. and why did he know Aria????? I NEED TO KNOW   

29. It’s not unheard of for someone to build a bunker          

30. I would like to know this      

31. Wasn’t it Lukas? He was having trouble walking when he was talking to Hanna like one or two episodes later.  

32. no one knows                             

33. To extend the show for another season so more money   

34. He’s doing great? We saw him? like sorry we didn’t get the last 6 years of his life and yea I liked him with Aria too but what is the problem here? 

35. Left because he was a terrible father?    

36. He played his role and then that plot was wrapped up

37. Police get away with everything don’t we know this already?

38. Do we actually care about this one? 

39. She was probably spying on them too? She was going to confess so she did some research

40. Ali was never a real suspect in Archer’s murder so they would not have a reason to take her phone. On the record, she was still in the hospital thing at the time of his death.

41. She didn’t know anything about Alison. That was all apart of the part when we thought Garett was guilty. Her death was all Nate

42. A’s favourite number? 

43. a red hearing?

44. Alex Drake? before she decided to fall in love with toby and take her life

45. Because obviously mental health awareness is not taught in their schools!

46. Because Pretty Little Liars was an amazing show! 

Please correct me if I am wrong on any of these or if anyone else has an answer for something I couldn’t remember!
