Cloaked spaceship around Mercury and a new Earth

Hi,

Some equations that might help. KE = ½ m(velocity)^2 Kinetic Energy, mass needs to be in kg and velocity in meters/sec.

(Wave Length) = h / (mass) (velocity). h = 6.63 x 10^-34 J sec

c = (Wavelength)(v) c = speed of light 3.00x10^8 v= nu or frequency

E = hv v= nu or frequency

Large Wave Length = Low Energy. Small wave Length = High Energy.

Maybe these will help with the transportation of shit over light project.

As for water. Hydrogen is approx 1g per mole and O is approx 16g per mole. To transfer 1 mole of H^2O you need enough energy to push 18g across your desired distance. And here is the equation for effusion = Square root (3RT/Molar Mass) T= Temp in Kelvins. R= 0.08206 L.atm / mole.

Bah, who needs math!

You can easily find the weight of each atom in that molecule and the density of water....the specifics should be easy to calculate after that. "thumbsup"

I asked the question for a reason. ;-)

You are a smart man, figure it out."thumbsup"

Yep, and for those of you reading there is a difference here between Kinetic Energy and Particle/Wave Energy....that difference is what I was talking about earlier....one applies in classical mechanics, the other in quantum mechanics.

1mole of a substance is 6.022x10^23 molecules.

So try 1mole O = 16g/6.022x10^23
and try 1 mole H = 1g/6.022x10^23

I might be incorrect, its been a while.

Not with math.

And from past conversations, not too much with physics either. :ror:

Basic principles I'm ok with, beyond that is no-mans land.

 

[JeremyH]

Yeah, I believe rnpick is right. It has been a while since I took chemsitry, but here goes:
Assuming one gallon of water.
Molar mass of water = 18g/mole
Weight of water = density*volume = 1g/mL*3.8L = 3800g
Therefore, there are [3800g/(18g/Mole)]*6.023x10^23 molecules/Mole = 1.3x10^26 Molecules in one gallon of water or 3.8*10^26 atoms in one gallon of water.

Which means that there are 2.5 *10^26 Hydrogen atoms and 1.3*10^26 Oxygen atoms in one gallon of water.

Edit...I forgot to multiply by the number of atoms in the water molecule....numbers are fixed now.

has anyone mentioned Sagan yet?

 

[JeremyH]

Carl Sagan

 

[JeremyH]

has anyone mentioned Sagan yet?

Yes, Duh...

 

[Mr.Slave]

carry on.

 

[Mr.Slave]

anyone seen the show "nova" i think it was on PBS.
that was some crazy stuff

There absolutely 100 percent for certain has to be life out there,

Just our galaxy our milky way is one hundred thousand light years across.

Light travels at 11,000,000 miles per minute. eleven million miles per minute !

We have estimated trillion stars in our galaxy.

The nearest star Alpha Centuri is 4 light years away or 26 Trillion miles

thats just our galaxy.

there is estimated 500,000,000,000 to one trillion galaxies .... each galaxy with billions and trillions of stars...


it happened again my brain imploded...

ya i think its crazy to believe there isnt life out there.
the vastness of it all and the sheer #s of stars makes my head hurt to contemplate it all:shock:

 

[JeremyH]

Agreed."thumbsup"

Its not necessarily about their weight, but about their size. Everything that we know of that has mass is still comprised of mostly empty space. Tiny subatomic particles pass through us and everything around us every day, not because they are fast or light, but because they can fit through the gaps in our own atomic structure.

Nothing is completely solid, even though it may seem that way to us.

Its weight and motion combined, against opposing weight.
if I gently toss a 80lb bag of sack of concrete at you, you will catch it.

If I throw it at you, your may catch it, but your gonna move back.

same thing, but with a 1lb bag of concrete.....your not gonna be moved by its weight, or impact speed.

now take the 1lb bag and throw it at you from a potato gun...the added speed, motion is enough to make you move.

Its all weight and motion

You're talking about force, which is a function of mass and change of velocity (F=ma). But I think you kinda missed Duuuuuuuude's point... with your same concrete sack example, if hurl that bag o crete at him with any kind of force, and miss him completely, he won't move at all.

Edit: just noticed I'm a bit late to the party, but this kind of stuff really interests me
