  1. As far as I know, light follows a geodesic trajectory of the curvature of spacetime, follows the so to speak „shortest path” in curved space and this is the interaction of photons with gravity (gravity is the curvature of spacetime) Even if photons are loosing energy to the gravitational field (I don’t know if this is correct?) it doesn’t imply that the conservation of energy is violated. Wow, I was not aware of this. I skimmed throug the first one and and I was convinced that it all hinges on the notion that gravitational waves in fact must carry energy but started to read Sean Carroll’s article and I’m stunned. I was just not aware of this. Looks like I have a lot of reading to do over Easter.
  2. The article seems to be highly speculative, there aren't any conclusions. I only skimmed thorough it but I see that it hinges on the brane model to try to push an idea that energy is not conserved on the universe scale and then at the end suggests that photon energy is conserved after all, which is strange. There's a statement in the first blue infographic which seems to either horribly contradicting itself or I am missing something: "Because each photon in the region becomes less energetic as space expands, this calculation suggests that the total amount of photon energy in the region and, by implication, in the rest of the universe must be going down" I don't see how the author arrived at the conclusion that the total energy must be going down if photons become less energetic due to spacetime expansion. It seems to be an irrational conclusion but maybe some of the more knowledgeable people can explain otherwise. Besides, even if it would be true that the universe is leaking energy to another brane it would not be violating conservation of energy.
  3. I’m just waiting to find out what happens to the energy which is not conserved. I presume it is teleported somewhere far far away like the pink unicorn dimension where fluffy bunnies distribute it to form rainbows.
  4. Looks like we have yet another Nobel prize contender. So many of these, the jury is going to have a hard time deciding.
  5. You’re right I guess but we won’t know if crows and/or octopus would channel more budget into science than into the military. Excluding the „unique” part, I think my point still stands.
  6. I think the dehumanising goes beyond morality. One of our very important human traits which makes us unique among other species is curiosity, the striving to know things and to discover. Every one of us has that when we are born and in my opinion it is one of the few traits in us which is actually beautiful, there is a certain nobility to it. Gods and holy books crush that in us and substitute it with their own primitive methodologies leaving an empty shell incapable of that spark. Its like cancer.
  7. My partner is significantly younger than me. Shes a PhD, I’m not - in fact I’m a moron. Should society accept us?
  8. Oh yes you're right, it's very stupid. Just like the rest of it.
  9. Are these over one thousand examples of cruelty and violence in the bible also all taken out of context? Or maybe the website owner is a crackpot too? Hint, he isn’t, look up Matt Dillahaunty as he is the reason for this website to exists: http://skepticsannotatedbible.com/cruelty/long.html Feel free to adress all ogf these in detail Raider. When you’re done we can move on to other „moral wonders” of the bible. You don’t even know what slavery is.
  10. I agree. There is a female in my example because I feel I’m too old with too much bagage to seek adventures with men now.

    about humour

    I must rephrase because as you noted my previous post might have been inaccurate or at least incomplete - Its not pathetic, its being a complete idiot. That is extremely rude, you’re lucky Phi’s got lots of class. You’re only hurting your own image with such remarks. Unless you’re in the wrong neighbourhood in real life and say something like that...then you might be in for more hurt than just your persona image.
  12. There is a bad smell flowing out of literally every word of the OP question.
  13. Some of them might be living outside of a xenophobic culture which in effect can lead to more insight on other cultures and broaden ones views. Im sure this can be a major con for certain people.

    about humour

    Jim Jefferies is one of my favourites.
  15. What people wrote above is pretty accurate and exhaustive. The bottom line is that its a subjective issue depending on personal character, previous experiences, the way you were brought up and in what environment, religious factors and dozens if not hundreds of more factors. There's no binary way of deciding if something is wrong or right with these things, as long as you are not intentionally hurting another person you're ok. The way I personally see it is, I couldn't be with a very jealous person who goes all over me whenever I make a comment on another attractive woman and I do not expect my partner to be a saint and not look at other men and comment on them - that would be unhealthy for me relationship wise. It might work differently for other people though and that's ok too. The main part here for both sides is be kind to each other or at least don't be an ***hole to each other.
  16. I don’t find it uncaring or cruel when my partner comments on a six pack of some celebrity, most of the time it motivates me to put down the candy bar I’m holding in my hand. Commenting on another woman in front of your female partner is a whole different thing and its such a complex issue that it calls for a PhD thesis. And Im not sure that would be exhaustive too.
  17. Copenhagen-based artist Johan Deckmann examines the complications of life through clever titles painted on the covers of fictional self-help books that appear to tackle life’s biggest questions, fears, and absurdities: https://www.sadanduseless.com/2018/03/diy/
  18. You're right, my mistake.
  19. Centrifugal force is the one pulling the car away from its straight trajectory when drifting with a car. Friction would be a nightmare to calculate because it would constantly change due to changing of tire temperature & wear, speed and position of the car. If you want data on a real car drifting google Nissan GTR R35 which has a stock onboard computer and sensors calculating and showing on an onboard display a lot of data in real time. I don’t think any drift car would give you any data on friction.
  20. You make me feel like I'm 18 again beecee.

    Today I Learned

    Late 70’s early 80’s, its not clear from this info. At 250 thousand dollars they were probably more of an experimental thing back then: https://www.google.pl/amp/s/www.geek.com/chips/teardown-inside-a-250000-10mb-hard-drive-1531755/%3famp=1
  22. That's ok dimreepr, I'm not offended by your belief.

    Today I Learned

    Today I learned that in the late 70’s, IBM used halon gass as a fire suppressant inside their hard drives which had air tight casings. The drives were 9 plates traditional mechanical technology, 10Mb capacity at 38kg weight, about the size of a full ATX desktop PC and cost around 250K USD. The story goes that the server rooms where the drives were operating were filled with Halon gas as well to mitigate the risk of fire.
  24. If you use a screwdriver on a poor quality screw over a long enough period of time, the screw gets damaged beyond repair. You can always drill it and use a new one. So the moral is, sometimes its impossible to turn a believer, you need to wait a generation or two for things to change.
  25. It’s pseudoscientific delusion based on pink unicorns. What made you post such a thing on a science site in the physics section? But hey, Im open to learn new things so lets see the „anti gravity” math.
