We've all seen or heard of Jurassic Park & I just wondered could we really have dinosaurs walking down the street? Not that there would be any street left because they'll have destroyed it.

But scientifically is it actually possible??

Also even if we did manage it wouldnt they just die in our atmosphere as it has changed dramatically since they last roamed the earth?

Let f(x, y) be a differentiable function from R^2 -> R, and let g(t) = (x(t), y(t)) be a differentiable function from R -> R^2.

Then the derivative of f(g(t)) is (f_x dx/dt, f_y dy/dt).

(I'm feeling low about my multivariable calculus knowledge.)

I do not believe in religion and the GOD as described in any religion. So if i want to discuss about the entity that created the universe i will call that entity BNT (lets call it anything .... but not GOD).

only those who do not believe in GOD(as told by religion) should answer this.

Lets say the entity BNT create the universe. If this was the case what do you think would be the character/attributes of BNT?

for e.g BNT would be in "pure energy" form. or say BNT is "energy+matter" which is in 27th dimension. or say BNT created the universe with "set of rules" but does not care anymore as to what happens in it.

A lot material on the internet say that the universe was created by bigbang and it started of with a single point and it blew up to the current state.......

I am no scientist, but just to imagine that this massive-massive universe was so much compressed at time=0 is unbelieveable to say the least.......Are there any proofs to really tell us that this whole stuff was just the size of single point?

Expanding universe could also have been from a initial mass say the size of a "galaxy" atleast.

inter galactic space was told to be occupied by "ether" later i read somewhere that this has been disproven.

my question is "vacuum" = "nothing" (the intergalactic voids)

if this is true then "gravitational force" has to be caused by "some kind of particles rather than waves right"?

Someone told me of a hunter who shot a bear that was 1/3 polar bear and 2/3 grizzly bear. I said that was impossible for the bear to have been 1/3 anything and 2/3 anything because the bear has TWO parents. So it can only be 1/2 polar bear and 1/2 grizzly bear.

Even if you go back another generation, the bear has 4 grandparents, not 3, so the proportions of grizzly to polar can only be measured with fractions that have denominators of 4.

I told him that if my father were Native American and my mother were Spanish, that would make me 1/2 Native American and 1/2 Spanish. If only my father's father were Native American and my other 3 grandparents were Spanish, that would make me 1/4 Native American and 3/4 Spanish.

I told him you could never be 1/3 anything because no matter how many generations back you go, you can never get a denominator common with three.
