Doubling the size of everything in the universe

[Zerzera]

It's funny you would ask this, because everything in the universe is already twice its size.

[Doc Flabby]

I don't think the universe could handle doubling the size of me :fear:

[Burzum]

If you managed in devising a model of the basic forces based on relative proportions between the interacting parts and nothing but those proportions, it might work. For all we know, we might be about doubling up in size every second and not be any the wiser.

A bloke out there set out to explain everything including gravity with continuous expansion.

It wouldn't work because as Pressure Drop said, there are relationships that exist in nature that aren't linear. Even in simple things you can see polynomial, exponential, and logarithmic proportionalities.

This is correct. Almost nothing in nature is linear.

[Bioture]

This is correct. Almost nothing in nature is linear.

It might not be linear, but let's take the equation E=mc2 for example, even though the speed of light is squared, if we doubled this equation, 2E=2(mc2), right? I'm not simply doubling the speed of light and the mass, because then it wouldn't be proportional to the joules coming out of the other side. Geez... I really wish I took another physics class in college.

When I say doubling the size, would it be possible if we double the size, while proportionally increasing the other factors, such as distance, time, energy, etc. and have it happen and have no one be the wiser?

[Ephemeral]

Everything would not be the same. Time would change.

as in change it in such a way you've changed nothing at all ?


i think you've got confused with algebra.

yes you do 2a +2b = 2c is the same as a+b=c

however

2(a^2) + 2(b^2)= 2(c^2) is not the same as (2a)^2 + (2b)^2
= (2c)^2

the latter is what you are doing if you are doubling everything in the universe the masses, distances etc as these are the factors the equations are based on.

how can you be doubling each individual equation when they are based on these values that you are doubling ? essentially you are disregarding the values then taking the equation as a whole and going
2a = 2b is the same as a = b

I just got done arguing this with a friend over AIM... but here's the argument (and I have no idea how this started, and why it lasted 4 hours - it's 6am here approximately)

The argument is that you can hypothetically double everything in the universe and everything would stay the same. Atoms, gravities, etc. Everything would be doubled to scale. Would this action doom the universe or would everything be the same, simply twice in size? We're assuming that everything in terms of density and mass is increase proportionally to the weight.

sorry just wanted your thoughts on this. it's pretty late here and what I wrote might become delirious banter when I read it in the morning.

Want to make spaghetti for 4 instead of 2? Just double everything in same
proportion. Yes it's simple chemistry :P

On the bare surface of things it might seem as if it might work, but it defies molecular mechanics, if everything did stay the same it would subvert properties of molecules, but then again, its a matter of whether the molecules actually double in size or double in number, if in numbers than i can see it being ok, but size no. Mind bottling(lol).

[DUMBRIT!]

mind bottling indeed!

The speed of light cannot be increased.

Consider this: when you spray water out of a hose it comes out at let's say 10 m/s. Now, if you were to run foward while spraying, your velocity would add to the speed at which the water comes out of the hose. Simple addition of velocities. Likewise, if you are running toward an arrow it will do more damage than if you are running away from it, or cars that get in a head-on collision have a greater impact then ones moving in the same direction at slightly different speeds. Okay, you get the idea.

When scientists began to study the speed of light they quickly came to one interesting discovery: the speed of light cannot be increased. If you run forward with a flashlight, the speed of light will remain constant, it will not increase as does any other physical body in motion. It's actuallt pretty weird if you think about it. if light were a particle it would increase in speed as do all other forms of matter. If it were a wave, it would also increase, as do sound waves, microwaves, etc.

To answer your question, if everything were increased in size, and the distances were also increased proportionally (including somehow all the non-linear forces which have already been pointed out) the speed of light would not increase, reducing the temperature of the universe. I don't know what would happen but it sounds bad.

An interesting topic.

Say you double everything, everything would have twice the molecules? So every molecule has twice the amount and type of atoms. So the atoms have twice the amount and types of core particles. Take 2-Hydrogen as an example. It has 1 proton, 1 neutron and 1 electron. Say you double the amount of protons. You then no longer have Hydrogen, but you get Helium. In this way Hydrogen will cease to exist when you double everything. Fatal consequences result from this.

I'm not sure if that is what you mean, but that's what I understood from it.
