Phi for All

No offense, but when presented with something that doesn't make sense to you (any of you), it's silly to call it silly. It's silly to just make something up BASED on your misunderstandings. You should ask specific questions about the specific things that you don't understand, and listen to the answers to strengthen your knowledge. The BBT follows the progression of the observable universe from an extremely hot and dense state through rapid expansion to its present structure. It's our BEST CURRENT EXPLANATION, and we know this because we can cross-check it with other things we know. If these things were wrong, we wouldn't be able to land craft on Mars, or even make our GPS system work.

Besides taxes not really representing a loss, since you benefit from them in other ways, it's also only around 10-25% of your wages. In your automobile analogy, you could be losing 80% of your energy due to internal combustion and the associated systems. Imagine if you only made 20% of what you do now, and there were no public roads, no libraries or parks, no public schools or airports, and no other services your taxes provide.

If you're speaking of a big bang, it's not right to think of it as an explosion. The BB was a rapid expansion of the entire universe. If you're speaking of a black hole, there is no "aperture" or opening in a conventional sense. And nothing is going to be propelled out of a black hole. Nothing has the energy to escape the insanely curved path through spacetime that leads to the matter at the core. Another common misconception due to popular science writers trying to explain gravity using only two dimensions. There is no "fabric" of space, and it's another bad way to visualize what's going on, because it leads to misconceptions like yours. In our best current explanation, the three dimensions of space are inseparable from the time dimension, forming the spacetime continuum. Gravity is produced by objects with mass and energy, and curves spacetime in predictable ways. This model (LCDM) also shows that dark energy is causing space between non-gravitationally bound objects to expand. This has no support whatsoever, but the same would be true if you claimed it was finite. There is simply no way to know if the universe is infinite or finite, using any kind of trustworthy methodology. It's not even something you could answer philosophically, afaik.

! Moderator Note Moved to Speculations. Please read the special rules for this section. You need to support your ideas with evidence, or have some maths to model what you're talking about. Please use mainstream science. Welcome to the forums.

Perhaps you have some misconceptions in that regard. Newbies who want to discuss mainstream science aren't shouted down, ever. Newbies who want to challenge mainstream science using their own made up, unevidenced pet theories get asked to follow the rules, which they often misconstrue as being shouted down. No offense, but this is the sort of comment that makes me think this is all about complaining. If this is a compliment, it's very back-handed. His name was blike, though, and I believe he practices medicine now, so yes, he's doing a good thing.

Bad analogy, I'm afraid. Taxes get used for something, but energy losses in physics are usually to unused heat and friction. A better analogy would be an unnecessary middleman on a deal, someone who does no real work but gets paid anyway. Or using private funding for something that would be more cheaply done with public funding, like building toll roads instead of public highways, where profit for the private company is taken unnecessarily from the system without doing any extra work.

Volunteers trying to provide a platform for discussing science. Volunteers with a limited amount of time. No offense, but you seem to be asking us for a lot of information you can use to complain about us. Others may have the time to update you on our development since about 2012, but I doubt anyone on staff does. Can't you slake your boredom in a way that involves more discussion about science?

! Moderator Note Some science would make this more interesting and discussable.

I'm so sorry, but I can't spend any more time on this thing you call a problem if you can't spend any time actually listening. Your problem is not your height. Good luck.

What a fantastic team of humans! Congratulations NASA!

Not sure if this is covered by your choices here, but Texas has gone out of their way to avoid selling or exchanging power with other states due to the costs of compliance with federal regulations. They've been beating the "Big Government" drum loudly, so it would be easy to just let them suffer, but it's hard to find properly informed Americans anywhere these days, and many of them would probably recognize reality if they were somehow exposed to it via their "news" source(s).

THAT explains the extra sag in them lately!

! Moderator Note We've been down this road before, and you have nothing new to show us, it seems, so you use these shitty, fallacious, bad-faith tactics to discredit your detractors, rather than analyzing the science they're bringing to the discussion to refute your racist agenda. Staff has decided we're going to treat this genetic superiority subject the same way we treat discussions about creationism. We just don't bother with such lunacy. If it looked like you had ANY interest in overcoming your current genetic ignorance, we'd be happy to discuss the topic with you. This type of post just shows us you've predetermined your stance, which makes you a preacher and a soapboxer, and discussion isn't the place for you. Thread closed, don't bring it up again.

We're missing some gravity?

Indeed. It seems romantic to romanticize them. These chaps require certain behavior around women, which they're more than willing to abide by if the women would give them a chance. But they also make far too many assumptions about women for someone who doesn't speak to them. The drunken slob is unworthy, yet he has no problems making women smile. A side effect of drinking too much can be exposing honest feelings, and if you're even halfway into someone, it can be powerfully attractive when they share like that. If you don't simply talk to a woman as a person, you might imagine she admires that tall guy she's looking up to. If you actually talk to her, you might find out that guy gives her a pain in the neck. Ultimately, the pedestal is insurmountable because we don't try to climb it. We're trying to jump up there all at once. That's what ends up making women nervous. A slow climb, getting to know the terrain as you go, is best. With people of any gender, talking to them and listening to what they have to say is the best way to get to know them. As a great astronaut once said, you can't open the book of my life and jump in the middle! Like woman, I am a mystery.

! Moderator Note That's the last time you call another member an idiot. Civility is our #1 rule, and you have chosen to defend a stance that is VERY weak wrt science. If you want this thread to stay open, you'll respond without insult or you can leave. Attacking ideas is what we do here, we don't attack people.

In cosmetics, powdered titanium dioxide is used to block UV rays, so how is it "reacting" to UV? It's being investigated as a carcinogen: https://www.independent.co.uk/news/science/toothpaste-additive-e171-titanium-dioxide-food-products-cancer-cause-scientists-a7541956.html

... as long as the picture has his mouth open.

I agree with Robert Reich. Enough is enough. Do away with the filibuster, forget the Republicans, and do the things this country has desperately needed for a LONG time. Go to war with the hypocrites and liars, because this democracy will never get better if we give them any say in leadership at all.

! Moderator Note This is blogging, and we're a science discussion forum. Nobody wants to discuss nonsense. Please don't post more like this.

I remember reading an article that claimed only 3 Republican Senators were needed to demand that they'll approve the trial conditions only if the ballots are done secretly. I think that would make a YUGE difference in the outcome of the trial. Has anyone heard any more about that?

Flowers are amazing for their ability to break ice. When you present them, the look on the person's face tells you the next step. They learned from the precedent set by the penis enlargement industry, another fine example of Truth in Advertising.

This doesn't help. This is what Republicans point to when they claim people are against him no matter what. You're making claims about his whole life rather than follow your own advice and stick tightly to the events of the riot at the Capitol. Again, I think this kind of emotion is misplaced at this point, but if you want to touch a nerve with folks, don't focus on what might happen. Focus on the fact that the ex-POTUS incited the Duck Dynasty to attack the same building the passengers of United Flight 93 died to save on 9/11. Foreign terrorists couldn't bring it down, but one ex-leader who broke all his promises to transition peacefully did it on TV and the internet for all to see. This is what most Republicans in leadership want us to condone.

Not sure there's any need, since they all have completely different objectives, but having so many vehicles in orbit has to give some advantage, even if it's just to check up on each other. The space policy folks are keeping a close eye out.

Perseverance joins both the UAE's Hope orbiter and China's Tianwen-1 spacecraft. Rather than separate threads, I'm hoping we can talk about the individual missions as well as this historical opportunity for multiple programs to work cooperatively a looooong way from home.
