Starship Asterisk*

Why Would I want to watch things, like lectures ? To learn. You claim to be after answers; you'll find the answers to some of your questions in lectures. I Know There Answers ! I do Not Believe Them. ( Some Of ) Because of changes of minds. One Day, We Have A Fact, The Next, We Are Not So Sure. Huh...

Mark, I asked earlier, didn't get an answer, so ask again: aside from the BBC videos, what other resources have you used to aid your understanding? Did you watch the lectures available here on Asterisk? Read the suggested Wikipedia articles? Read a textbook or two? Take a class, either traditional ...

For Me, The Communications Center: Breaking Space News This For Me, Is The Best, I Have Ever Encountered On The Web. Thank You Bystander And All Else Involved. For all your hard Work. I do not need to go looking Now, Because I know, If its out there, I will find it here. Thanks Guys. Mark

I would like to speak about tides on the Moon. I know this is a shocking way to express myself, because there is no water on the Moon. However, i was told there was some sort of "tides of rocks", due to the earth gravity. When i sea pictures of the Moon, i can hardly imagine that there ar...

Chris, Your going to tell me, Its all by Magic Huh ? :shock: The Mass of the Sun, "distorts" - "Something", ( that was never created), that keeps us (Planet Earth) in Orbit. (And At, "t = 0") It did not exist. No magic is required. Along with no explanation. tc

tc No, Chris. They are not. I Must now quote: This is what your talking about http://www.youtube.com/watch?v=GkCWywO93b8&feature=related http://www.youtube.com/watch?v=LfCv9GLwvYE&feature=related http://www.youtube.com/watch?v=i-mrj1qrCFk&feature=related http://www.youtube.com/watch?v=AA...

A: What is time? Answered, and in many respects understood. B: What is the cause of Gravity? Well understood, and fully described by GR. Whether gravity can be understood in term of QM is still an open question. Again, you're looking for answers that already exist. No, Chris. They are not. I Must n...

Chris, do you have "Time" to explain "Special Relativity" a bit ?? That's about as much time as I have. In case you missed them, there are some nice video lectures by RJN about both SR and GR in the Physics X forum right here on the Asterisk. The Math does not Add up. I heard it...

The BB made more Space Time, than, what we see as matter. Why? Does Space Time have to clump together because of the Form it took before the BB? That been so, Space time been a physical entity, Does it Flow like water? The Less the Flow the more restricted by time you are? Where stars are concerned,...

Hi Folks Interesting stuff All, Great Read. So, If I read this right: Our Universe goes through cycles, Nice. Evidence of activity before Time Started, Excellent. So you don't need all the Matter/Energy in the Universe For A big Bang, Tremendous. OJ287 Springs to mind, Which could only be: The Next ...

Why Is The Suns Corona Hotter Than The Sun Itself

what is the reason? What could be the reason?

A Real new Moon 4 billion years, 4 billion centimeters. The Moon slows down the Earth's spin, The Earth slows down, the Moons speed. 2 miles of ice over New york. Is there another reason? You Know Where I am going with this. Four Billion Years and the Moon is still here. Can the Moon actually leave...

The moment A supper massive star, Starts fussing carbon to Iron/Heavy mettle's etc etc. They say the big star's life is over, within seconds. This is my Question. Why does not, The falling in of 20 or so, heavy Iron core planets, falling into the sun, have any effect on its fusion? or Did it? tc

Dangerous Knowledge.

At what point does my eagerness to understand Gravity and Time, move from A little interest, to an infernal Obsession?

I will Now take note, to this eye opener. 1st of 10 Links :

The whole universe, as it is now, took about 13.7 billion years to form. The first stars and galaxies didn't form until about 400 million years after the big bang (the advent of reionization ). A universe we might recognize wasn't until after reionization, about 1 billion years after the BB. The fa...

Thanks, Mark. I actually meant to post this Friday and it somehow got lost in the shuffle. When I saw your post I went looking for where I posted it, not to be found of course. I thought it was an interesting article. Here is the referenced paper: Asymmetric Dark Matter and the Sun Physical Review ...

What i don,t understand is: The expansion either way, with out tipping the scales. To a big crunch, or a big Rip. Its like inflation stopped and something else took its place. Or are they both the same thing? That is an important, and open, question. Most people consider the two to have fundamental...

There ya go.

ps. I Don't do universes if its more than ours. We need to understand this one first Huh?

Unless your Photon, is 13.3 billion light years away, And expansion is accelerating and your Photon will never get here. It won't necessarily get here in an accelerating universe, no. Whether it does, depends on how fast the acceleration is. My calculation above assumes an acceleration of zero. Cle...

The information in my example is in the form of a photon that always travels at speed c relative to the galaxies it passes on its way towards us. Nevertheless, given enough time it eventually reaches us even though it started at a galaxy whose distance to us increases by more than one lightyear a y...

Milne's model is a particularly simple instance of a class of models known as Robertson-Walker metrics. When Chris made his claim, I assumed that he was envisioning an argument for it that would work in all Robertson-Walker metrics. Such an argument would necessarily be flawed, as I have shown by e...

No bite yet then? Perhaps because there's really no story. There have been occasional suggestions over the years that various physical constants are not actually constant. This is another such claim. It is highly speculative and poorly tested. At the moment, there is a vast amount of evidence that ...

I have no idea how they work, "If" they work. But since i put these around my house last autumn, I have not seen any spiders period, in my home. And here they are: http://www.dailymail.co.uk/sciencetech/article-1217709/Do-conkers-drive-spiders-bonkers-Royal-Society-Chemistry-tests-old-wive...
