Here is what I mean... Suppose everything in our universe was doubled in size... People... the Earth... the Stars... EVERYTHING... would the laws of physics stay the same? Would anything be different? Would we be able to tell that somehow that everything is now doubled in size?

Is it all about the vocal cords, everyone has unique vocal cords/
the harmonics of sound production in the human body in general/chemical signals in the brain moderate it? Do identical twins usually have pretty similar sounding voices? There are billions of people on earth, and so many subtle differences that make us all sound unique.

Is Time Travel practically possible? If yes, do we really exist at present? are virtually living in the past? When we mention time travel to the past, does it refer to a travel within the earth or somewhere out there in the space?

I lived in China for 11 years and rarely saw teens whose face grew pimples, why is that? I mean shouldn't it be the opposite due to pollution? Many people say that pimples have nothing to do with diet....

i just thought about this and if thats the case, then our universe isn't infitine? i know they call a circle infinite but what i mean is a circle is a line that keeps going going but never really going anywhere new.
wait a minute a line is infinite not a circle! what!? could the universe that our galaxy is in be inside some black hole?

When using the quadratic formula to solve a quadratic equation (ax2 + bx + c = 0), the discriminant is b2 - 4ac. This discriminant can be positive, zero,
or negative.

Create three unique equations where the discriminant is positive, zero, or negative. For each case, explain what this value means to the graph of
y = ax2 + bx + c.

I used to hear peope say it was staged and faked, and I always thought "wtf, we went to the moon, its not that rediculous" but then, recently I heard the question arose once again, but behind it was a great following and they wanted to review the raw footage of it. Then, merely a week later, NASA says they seem to have misplaced or lost the original footage. Now, isn't it odd that they misplaced a direct record of the most important advance in exploration to mankind? And only a few days before professionals were going to analyze it? And why has NASA suddenly commissioned Lockheed Martin to build a craft that will put man on the moon? What does this mean? Was it really a fake? Have I been duped?

three kids went to buy a toy for 30 pounds , so every one of them paid 10 pounds, then they took the toy and went away. after a while, the shop owner realised that the toy's price is 25 not 30 . he decided to repay the kids their 5 pounds , but when he was on his way to the children he stole 2 pounds , so he gave each kid one pound... so if we calculate how much did every kid paid for the toy it will be 9 pounds . if we multiply nine by three (three kids) it will be 27... plus two pounds that the owner of the shop stole it will be 29 (not 30) ...... so there's a lost pound ... how ?

1.) V=2*pie*r divided by t t= r=
(answer: t=2*pie*r divided by v),
(answer: v*t divided by 2 * pie)

2.) d= V sub0 * t + 1/2 * A * T square a= vsub0=
a= 2(d- V sub0 * t) diivided by t square
v sub0= (d-1/2*a*tsquare) divided by t

3.) t= 2 * pie * Square root of l/g l= g=
l= T square * g divided by 4 * pie square
g= 4 Pie square * l divided by T square

4.) a= 4 pie square * r divided by t square t= r=
t= 2 pie * square root of r/a
r= a * t square divided by 4 * pie square

5.) V sub f square = v sub 0 square + 2 a * d
v sub0 = vf square - square root of 2 a * d
d= v subf f square - 2 v sub 0 sauare divided by 2 a

6.) d= 1/2 (v sub 0 + v sub f) * t v sub f = t=
v sub f = 2 d - v sub 0 divided by t
