If the universe is infinite, does everything exist?

Just to let you know, the big bang isn't quite like an explosion. It's suppose to be an expansion of hyperspace where the distance of all things from each other increases rapidly, though supposedly without a center. There's a book and a video called Starlight And Time, which has an explanation of the George Gamov version of the universe (the big bang) and presents the development of the first Creationist cosmology to incorporate the general theory of relativity.

No! Infinite doesn't mean all. There are an infinite amount of numerical values between 0 and 1, but not a single one of them is equal to 6.

true and something that people will fanatically refuse to even try to accept...

I suppose I'm fanatically refusing to accept this scientific law that "the universe is all there is and nothing more" when I say that it is not nonsense to think there is an outside to the system? Of course, human knowledge is perfect, complete, and whole. There is nothing beyond the material universe, because their is nothing beyond our knowledge. Yep, so fanatic to disagree with human omniscience. Omni scientia est nostri!

are you serious?
so when i say something, then its "oh the perfect human knowledge, mock in rhymes" but when you say it, its In My Face.
lets go back to where we had no contact. you bore me.

Advice: When talking about something scientific, try to know a little bit about what the hell you are talking about. Read this and you might actually learn something.

Yes, the big bang is not an explosion, and the addition of matter and energy created ex nihilo isn't all at once. What is does have though is the expansion of hyperspace in such a manner that the Copernican Principle is upheld. All points moving away from each other equally, so that the observational data that redshifts increase evenly the farther out we look in all directions can be interpreted as being the same view from all points in the universe.

it should be called "the big woosh" and "an expansion" and people would understand it better.
people imagine some sort of cosmic hand-grenade...

I'll add that you lack a basic understanding of the 2nd law of thermodynamics.

"Applications to living systems
Main article: Entropy and life
The second law of thermodynamics has been proven mathematically for thermodynamic systems, where entropy is defined in terms of heat divided by the absolute temperature. The second law is often applied to other situations, such as the complexity of life, or orderliness. [14] However it is incorrect to apply the closed-system expression of the second law of thermodynamics to any one sub-system connected by mass-energy flows to another ("open system"). In sciences such as biology and biochemistry the application of thermodynamics is well-established, e.g. biological thermodynamics. The general viewpoint on this subject is summarized well by biological thermodynamicist Donald Haynie; as he states: "Any theory claiming to describe how organisms originate and continue to exist by natural causes must be compatible with the first and second laws of thermodynamics."[15]

This is very different, however, from the claim made by many creationists that evolution violates the second law of thermodynamics. Evidence indicates that biological systems and evolution of those systems conform to the second law, since although biological systems may become more ordered, the net change in entropy for the entire universe is still positive as a result of evolution.[16] Additionally, the process of natural selection responsible for such local increase in order may be mathematically derived from the expression of the second law equation for non-equilibrium connected open systems,[17] arguably making the Theory of Evolution itself an expression of the Second Law.

Furthermore, the second law is only true of closed systems. It is easy to decrease entropy, with an energy source. For example, a refrigerator separates warm and cold air, but only when it is plugged in. Since all biology requires an external energy source, the Sun, there's nothing unusual (thermodynamically) with it growing more complex with time."

"The heat death is a possible final state of the universe, in which it has "run down" to a state of no thermodynamic free energy to sustain motion or life. In physical terms, it has reached maximum entropy. The hypothesis of a universal heat death stems from the 1850s ideas of William Thomson, 1st Baron Kelvin who extrapolated the theory of heat views of mechanical energy loss in nature, as embodied in the first two laws of thermodynamics, to universal operation.

The idea of heat death stems from the second law of thermodynamics, which states that entropy tends to increase in an isolated system. If the universe lasts for a sufficient time, it will asymptotically approach a state where all energy is evenly distributed. In other words, in nature there is a tendency to the dissipation (energy loss) of mechanical energy (motion); hence, by extrapolation, there exists the view that the mechanical movement of the universe will run down in time due to the second law. The idea of heat death was first proposed in loose terms beginning in 1851 by William Thomson, 1st Baron Kelvin, who theorized further on the mechanical energy loss views of Sadi Carnot (1824), James Joule (1843), and Rudolf Clausius (1850). Thomson’s views were then elaborated on more definitively over the next decade by Hermann von Helmholtz and William Rankine."

The short answer is yes, everything that can exist does exist.

I think the universe is full of everything which could not violate the laws of physics like for instance cows flying around the moon. Or even the existance of angles. But I am sure there must be other Earths out there because they would not violate the laws of physics. A tiny fraction of them would be almost like a carbon copy of our earth whereas most may share fact that life exists on them.

There's a deference between violating a law and superseding a law. Also, all scientific laws are descriptive and cannot be prescriptive.

But I'll have you know that a man named Euclid of Alexandria believed in the existence of angles,
and he was smart enough to give high school students headaches even today.

It rather depends what you mean by "empty" - if you point your spacecraft "up" out of the galactic plane and fly a few hundred miles up you'll find somewhat empty space (as in hard vacuum). Fly a couple of light years and you'll find more empty space as you leave the solar system. Fly a thousand light years "up" and you'll find very large areas of even emptier space as you leave the galaxy completely.

I'm not sure what would happen if you just made sure your spacecraft was out of the way of things and waited for an extremely long amount of time - everything might appear to recede around you until you were left alone. Athough expansion might break your ship apart... really not sure.

(edit) The extent of the solar system is a fairly debatable thing, but a couple of light years should take you well clear of the Oort cloud. I'm less sure about the distribution of the interstellar medium - dust and whatnot - around the galaxy, but a thousand light years is probably enough to clear the main body of stars, they're in a fairly thin disk towards the outskirts, where we are (there's a bumpy bit in the middle though.) Then you've got a distance to the nearest proper galaxies, many times larger than the diameter of the Milky Way. Very empty.
