Not since the Big Bang.
Your question seems to suggest that you accept the idea of a Big Bang, since you use the term 'Big Bang' as a reference to time.
The concept of infinity also is used in reference to time. unending time.
Time as we perceive it began at the instant of the Big Bang. Along with space. The space we see out there that we call the universe, with all the energy and matter contained in it, which seems to be fated to expanding ever faster with time. Time as we know it.
We think of time as time forward or time back. We seem to think of infinity as time forward. Knowing what we believe to be true of the universe, today, during our time, makes it difficult to think of an infinite time in the past because of our concept of the Big Bang. It is an indelible reference point in our mind when we try to conceive of the universe and its beginning, in time. Time back. But to a point. Not infinitely back. An infinite future time is not so difficult to imagine.
If this time is the only one we can perceive, and we can see that at this time ( a manifestation of space-time), there is all this expanding space with all its energy and mass (again, two manifestations of the same thing), then we must accept the notion that there is something, not nothing. At least since the Big Bang.
The instant of the Big Bang, the beginning of time and space, ended the possibility of an "infinity of nothing". All of a sudden, there is something.
In any discussion of infinity-eternity-everything-nothing one should research the concepts of "dimensionality and branes". Try looking up M-theory.

It does, or it can, suggest an infinity past. It is no less reasonable to theorize a past infinity as it is to theorize a future infinity. We convince ourselves that a future infinity is meaningful while a past infinity is not, but this comes more from the limitations of our minds than anything else. Either way you are talking about an infinitely long stretch of time, with one terminus in time.

True. Any further discussion must surely include the possibility that our universe was born in the 'Big Bang' event, and that the 'Big Bang' itself occurred when two 'branes' collided in a larger 'multiverse' of eleven dimensions. But if you go into that particular discussion, you must discuss gravity and it's strength relative to the other known physical forces, and perhaps the idea that gravity is a force acting within and throughout the 'multiverse' and distributed in some way between all the universes that exist within said 'multiverse. The other thing we don't wanna' discuss here then is the concept of 'time' as it relates to the 'multiverse'. Makes me shudder.
The Big Bang created spacetime, our universe as we know it and all of the matter and energy in it. The laws of physics in our universe were born of the initial conditions of the Big Bang.
The big bang did not happen somewhere out in space. It created space; and so from our point of view, it happened everywhere.
It is inaccurate to say, "There was nothing before the big bang." It is only true that there was nothing of our particular universe before the big bang.
We really don't know why or even how it happened, although many theories abound as to how, some shakier than others. Some believe our universe somehow "budded" from another universe. We may never know all of it.
A friend of mine in my teenage years once asked me, "Could the all-powerful God make a rock so big that he could not lift it?" My answer, paraphrased, was, "Yes he could easily do so. But you, being of this world, could not perceive a successful result to your contradictory test."
As far as we here are concerned, there isn't/warnt/unwere'be/'taint nothing scientifically testable before(whatever before means) the big bang.
Most scientists believe that an infinite dense singularity existed before the incident known as the Big Bang.
they were....long!
Primary succession results in a new community where no previous vegetation existed before, unlike in secondary succession which occurs where vegetation existed before and was destroyed either though human activity or naturally.
None.
No. The holes in the ozone layer formed years before H.A.A.R.P. existed.
No, infinity is not measurable, so infinity plus infinity is just the same as infinity.
Nothing existed before creation because nothing was created. Only God existed.
No - Nothing existed before 'Biblical Times' except God.
Infinity itself isn't a number in the conventional sence therefore not only is there everything before it there is nothing Ie. If 10,000 were the value of infinity I could add 1 to it and that would become infinity so unless somebody finds the point at which numbers stop ascending there will never be a value before infinity, find ding that point is impossible because as I have said before if you pick a number you can always add 1 to it.
If you believe in creation, you understand that nothing existed, not even the Nile River, before Creation.
Infinity is not a real number, it is an expression used to determine a continuous cycle that goes on forever, so there cannot be a number before infinity.
Nothing. He died long before Google ever existed.
Nothing. They were centuries before anyone knew North America existed
Most scientists believe that an infinite dense singularity existed before the incident known as the Big Bang.
Infinity is an imaginary number so if you meant the previous whole number to infinity it would be expressed as infinity minus one. If you meant the highest number possible before reaching infinity is would be: infinity - 1/infinity
Negative infinity plus one.
Nobody did. Neutrons have always existed. Earnest Rutherford suggest neutrons might exist about 11 years before their existence was proven.
