Oxygen discovered on Rosetta comet, stunning scientists

Scientists have for the first time detected oxygen on a comet, a finding that could upend theories about how the solar system was formed.

Reporting their findings in the journal Nature on Wednesday, an international team said that they detected “a lot” of molecular oxygen in the cloud of gas, or coma, surrounding the nucleus of comet 67P/Churyumov–Gerasimenko.

While molecular oxygen has been found in Jupiter and Saturn, it’s never been found on a comet. The neutral gas comas of most comets are composed largely of water, carbon monoxide and carbon dioxide.

That now convinces me that you are Janneseti's long lost son.

What?
The closest to Croatia I have been to is Rimini Italy.
Is this not rather OFF TOPIC?

According to Rosicrucian teachings there is no beginning nor is there an end, only changes.

The Anglican Church also teaches that.

Glory be to the Father, and to the Son:
and to the Holy Ghost;
As it was in the beginning, is now, and ever shall be:
world without end.
Amen.

Human beings live in a finite universe, we get born, we die. We can see the length, width and depth of an object. The concept of infinity is alien to the human psyche, and always will be.


The concept of infinity is an interesting study for mystics.

The concept of infinity is very much explained by Isaac Newton.
He even made mathematical tools and methods to handle the concept called Calculus.

Infinities exist in mathemtics. There are several kind of infinities, starting with natural numbers, then rational numbers, then real numbers, the complex numbers. On the x axis, there are infinite points between 0 and 1.

The short answer is No.

True.
Knowing that cardinals and ordinals in math could explain things like eternity and nothing are crucial.
Infinity is not a number and cant be used in math.
If it could then 1+1 would be 1 :)

You obviously don't understand number theory.
There are three special numbers:
0, infinity and Square root of -1
These special numbers enable the remaining numbers to work correctly

You can always add one or PI to Numbers and get a larger number.
Not to infinity!
Infinity + 1 = Infinity.
i + 1 > i.
0 + 1 = 1.

That is exactly why "zero", "i", and "infinity" are defined as special numbers - you need them to work out a lot of other things, but they do not behave in the way that normal numbers do.

Pi is a value (constant), not a number.




(Note - "i" in this context, and my previous post is the square root of -1, not an incremental value)

Number theory is perhaps the most difficult part of mathematics. The Riemann hypothesis is still to be proven and Enrico Bombieri ,now at the Institute for Advanced Study in Princeton, was promised a Ferrari by his banker father if he proved it. No avail.

Yes ! The discussion brings to mind what I have commented on before. There are numbers smaller than any real number but still greater than zero--these are infinitesimals. By extension their reciprocal is larger than any possible real number. These are useful ideas in explaining calculus and I think useful for getting around the part that we throw away or ignore in Calculus of (dx)(dy).
I have also opined that this is precisely what the Heisenberg uncertainty principle is trying to say.

As for the imaginary number "I" or the square root of -1, This is very useful in defining the real world of physics. Rotating machinery and AC theory makes very good use of this imaginary number to explain and understand Electrical Engineering.

Going back to Philae.
The trip to the comet followed Newton's laws of motion and gravity very well despite the fact that very small particles in a very near distance to each other doesn't follow the rules.

Tesla would be lost if that imaginary number didn't "exist".
Calculus deals very good with infinity.
But we live in a finite universe.
The Heisenberg uncertainty principle and Planck's theories is sort of the basic of quantum mechanics.
You cannot divide space or time in pieces for ever.

Yes it does for the everyday, macro world. Perhaps not in the micro-world where Planc and Heisenberg explore with their work. I always felt a little queasy --even as a college student-- with the fact that we keep x(dx) or y(dx) but throw away (dx)(dy). So I say at the limit we are approaching zero but maybe we can't really converge to it. The thought recurs that quantum weirdness may come from the artifacts of our mathematics.
