I was lost and helpless after trying so many ways to make my husband take me back. One day at work, i was absent minded not knowing that my boss was calling me, so he sat and asked me what its was all about i told him and he smiled and said that it was not a problem. I never understand what he meant by it wasn't a problem getting my husband back, he said he used a spell to get his wife back when she left him for another man and now they are together till date and at first i was shocked hearing such thing from my boss. He gave me an email address of the great spell caster who helped him get his wife back, i never believed this would work but i had no choice that to get in contact with the spell caster which i did, and he requested for my information and that of my husband to enable him cast the spell and i sent him the details, but after two days, my mom called me that my husband came pleading that he wants me back, i never believed it because it was just like a dream and i had to rush down to my mothers place and to my greatest surprise, my husband was kneeling before me pleading for forgiveness that he wants me and the kid back home, then i gave Happy a call regarding sudden change of my husband and he made it clear to me that my husband will love me till the end of the world, that he will never leave my sight. Now me and my husband is back together again and has started doing pleasant things he hasn't done before, he makes me happy and do what he is suppose to do as a man without nagging. Please if you need help of any kind, kindly contact Happy for help and you can reach him via email: happylovespell2@gmail.com<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8611810694571930415.post-15217489431180392802016-02-27T23:12:22.509-05:002016-02-27T23:12:22.509-05:00The definition of "fabric" includes &quo...The definition of "fabric" includes "form" and "construction" and "framework."

As I sit motionless in my easy chair putzing around on the internets for an hour, I am actually also hurtling through space.<br /><br />First, the earth is rotating, spinning around the center of gravity of the earth-moon system at about 1,000 mph. Second the earth is revolving, spinning around the center of the sun-earth system at about 66,000 mph. Third, the galaxy is spinning, so the solar system is moving around the center of the Milky Way-Sun system at who know how fast (the google machine digs up a speed of 515,000 mph). Fourth, they say the universe is expanding (language, but it is really not) So the milky way is hurtling at some unknown speed away from the center of the universe.<br /><br />So giving coordinates on the surface of the earth as if those represent fixed coordinates in space is not accurate, but in order to make any sense, a person must have a starting point, chosen here as the center of the earth.<br /><br />Modern physics, instead of describing three dimensions of space with objects changing their positions in it over time - chooses to describe reality as if there were actually four dimensions - x,y,z, and t. Stuck inside a three dimensional reality, we cannot even visualize 4 dimensions except in mathematical equations. After all the y axis is 90 degrees from the x axis. The z axis is 90 degrees from both x and y. Now insert the t axis, 90 degrees from x,y, and z.<br /><br />Good luck, and may the force be with you.<br /><br />Go back to that bowling ball on the trampoline. Instead of rolling some mindless marbles at it, let's put Antman in a working hot wheels car. Send him on the same path as a marble (or a light beam). Well, instead of blindly being pulled towards the bowling ball, Antman has the option, does he not, of turning the wheel and hitting the gas, so that he continues to drive in a relatively straight line?<br /><br />How is that possible, modern physicist, if space is really being bent? A simple car is somehow un-bending it?<br /><br />Fun questions for a college sophomore who wants to believe he can understand the universe, and somewhere people are getting paid decent money to engage in this kind of mental masturbation, but now that the mail has been delivered, I will take another beer.<br /><br />yours,<br />CliffyDr. Tnoreply@blogger.comtag:blogger.com,1999:blog-8611810694571930415.post-62068852332919227552016-02-25T17:50:45.456-05:002016-02-25T17:50:45.456-05:00You asked:"in what way can "space and ti...You asked:"in what way can "space and time" be regarded as a fabric? Why would anyone say such a thing? Under the circumstances, this seems like an obvious question." The notion is that they are not independent, and that they affect one another, time and space being aspects of something called "spacetime." Unfortunately, "fabric" is about as good a metaphor as various authors have been able to come up with, a thorough understanding of relativity requiring understanding physics after Newton and high level math. So us schlubs are stuck with only somewhat adequate metaphors.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8611810694571930415.post-24600530483899908972016-02-25T17:19:24.399-05:002016-02-25T17:19:24.399-05:00It's a guy's name.It's a guy's name.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8611810694571930415.post-77585596288310897062016-02-25T16:34:42.233-05:002016-02-25T16:34:42.233-05:00Just be glad you don't have to explain Minkows...Just be glad you don't have to explain Minkowski!Bartmanhttps://www.blogger.com/profile/06809097953780642925noreply@blogger.comtag:blogger.com,1999:blog-8611810694571930415.post-69697413762804251062016-02-25T15:59:37.827-05:002016-02-25T15:59:37.827-05:00Sadly, your question is important.

Each number is connected to all the other numbers in a specific manner. This interconnection is why it is commonly referred to as a "fabric", where each thread is woven together with other threads and they are affected by each other.
