They are cloaked to mesh right in with the sky (night or day)...did you think it would be simple to see them? What about the Arizone Lights? The O'Hare airport ufo? Roswell? Kecksberg? ...do you think anything paranormal HAS got to be fake? Why do you doubt what I say is true? I swear to you. The truth is out there!

how would its existence explain the accelerating expansion of the universe? is there really dark matter out there, or do we just not yet fully understand the physics of space and time? the apparent existence of dark matter could just be an error in einstein's equations right? thank you for your answers ahead of time and have a great day!!!!!!!!!!!!!!

Let's say I take a piece of paper and place it in the middle of the universe, stationary. Everything else is smaller than this piece of paper. Would the paper exert gravity on the smaller objects? If so, how small would the objects have to be, or how big would the piece of paper have to be to have them rotate around the paper? Does an object have to be a specific shape to exert gravity or rotate a certain speed? This is an honest question.

I had the question when I was studying polymer physics. I can understand that polymers in melt will have smaller R than in good solvent (due to the space packing entropy as explained in de Gennes' book), but I could not understand why it should have exactly the some size as the non-self avoiding randomwalk.

Let me first remind you that I am not at all psychotic. This is not denial either because I do know some crazy people post weird things on here. At random times this sound will go in my left ear, never my right. Like at random times, but never when I am asleep. It's just like this "mmmm" "mmmm" "hmmmm" sound like a spirit is trying to say something to me, but can't. What is it?

Consider light year speeds (and other units of measure related to physics that I know nothing about), Earth's orbit, resources we have on earth. Would our orbit come to a stand still or just spin off in one direction?

Since Deoxyribonucleic Acid is an acid, what is its Potential (Power) of Hydrogen (pH)? How can an acid carry genetic materials. Why is it an acid if there is no pH? Does DNA have a sour taste? If not, it could have been DNB (Deoxyribonucleic Base) or DNS (Deoxyribonucleic Salt). Who called it DNA and why is it named DNA? How can we taste DNA if it is a super-microscopic genetic material? Same goes to RNA.
