If the universe is infinite then surely there can be no such thing as the speed of light as there is no start point and no end point?

Logically incoherent. Who said you need to use the entire universe to measure
the speed of anything ? Simply define your own start and end points, and then
measure the time light takes to travel between them. The points can be as
mundane as two opposite walls of the restroom in your laboratory.

Is the matter in a black hole falling back to the point of origin of the universe?
The matter in a black hole is compressed by gravity to a singularity, a single point of infinite density. It goes nowhere except into that point.
If the universe is infinite then there can be no such thing as the speed of light as it has no start point and end point therefore there is just a constant the past and future exist at the same level?
The question is a logical mish-mash. Who said you need to use the entire universe to measure the speed of anything ?

What are inside a black hole in space?
In the center of a black hole is a region of spacetime called a singularity, a dimensionless point of infinite density, infinite gravity and infinite space time curvature, where the familiar physical laws of the universe no longer seem to apply, and counter-intuitive effects may be apparent, like the complete stoppage of time itself.
True or false an infinite number of lines can be drawn through one point if false then why?
In principle, yes an infinite number can be drawn, but in practise you would run out of graphite to draw the lines before getting to an infinite number. Even if you converted all the matter in the universe to graphite (using some Star Trekian style technology), you would still run out.
What is the source of all light in the universe?
There are 2 ways to answer this question. A: I could bore you to death with a 20-page essay. B: I could simply say that every point in the universe is lighted by the nearest star. Some parts of space are desolate of stars, and so they are dark and without light.
What is the primary source of light in the universe?
Every point in the universe is lighted by stars.

What is an open flat Universe?
This is a theoretical model of the universe. A Friedman Universe can have positive, zero or negative curvature. If the curvature is positive then the universe is closed and curved. A light ray going in any direction would make a complete circuit if the universe and return to the starting point. If the universe has zero or negative curvature it is open and unbounded and said to be flat. A light ray would travel in a 'straight' line and not return to its point of origin.
How much did all mass weigh at the big bang?
Weight is a function of gravity. Gravity is determined by proximity to mass. At the point of the big bang, all the mass of the universe (which is said to be infinite) was compressed to a single point. Therefore the pull of gravity, and thus the weight of that mass would also be infinite.
Does the singularity responsible for the Big Bang have a rotation?
Your question betrays a common misconception about the Big Bang -- that is was an expansion from a single point -- a singularity -- into a large, empty space. That is NOT what happened. Rather, the Big Bang was an EXPANSION of ALL space, at ALL points in our Universe. Every spot in our Universe was, about 13.8 billion years ago, of equal density, and that density has been decreasing ever since. The point 20 billion light years from our Earth is no closer, and no further, from the place of the start of the expansion that where we reside. Your misconception probably arose from the oft-repeated, but VERY misleading statement, about the OBSERVABLE universe -- a sphere of radius 46 billion light-years -- being once smaller than a proton. That's true but completely irrelevent, because that fraction of the total universe that we happen to be able to see is just an infinitesmally small part of the total Universe. It's quite possible that our Universe is infinite in size, and has always been infinite in size. Thus, our Universe has NEVER been a singularity -- and thus, it could never have had a rotation.

In the infinite universe theory does the universe have no beginning and no end just like numbers from negative numbers going to positive numbers?
There is reason to believe that there is an infinity of space out there, just as time is infinite, both in the past, and in the future. At some stage in this infinity of time and space, our universe began. In fact, the multiverse hypothesis says that our universe is only one of many such universes that have come into existence, or will in the infinite future. However, Einstein proposed that our universe (and therefore each universe if the multiverse hypothesis is correct) is curved, so that it in some way has an outer boundary contrary to Professor Hawkins saying the universe may have no boundary as the universe is possibly self contained. Minority viewpoint: The Infinite Universe Theory states that the universe exists everywhere and for all time. Thus the universe had no beginning, although each part of it has a beginning and an ending, being assembled from other parts in the necessarily Infinite Universe. This is in tune with the First Law of Thermodynamics (Conservation), which states that "Matter and the motion of matter neither can be created nor destroyed." The opposing assumption is Creation, the belief that something could be created out of nothing. The Big Bang Theory of the origin of the universe is wildly popular largely because most people follow religious tradition in assuming Creation. In tune with that logic, modern physicists accept numerous odd claims such as the shibboleth that space could be curved even though it is supposed to be completely empty.

How does a black holes get more mass?
A black hole gets more mass by sucking in more matter, i.e. a star or a cloud of dust. However, they do not have infinite density, because they are not infinitely small. Therefore the star that left it behind after going supernova (exploding) did not contract to an infinitesimally small point, and so even if it sucked all the matter in the universe it could not get infinitely dense, since the universe is not infinite.
What numbers go on and on past the point where they can be calculated?
Infinite numbers go on and on past the point where they can be calculated. The numerical value for pi is an example of an infinite number.
What is the scientific evidence of creation?
This is a great question that needs to be asked more often. To start it's practically impossible for the universe to have exploded out of nothing or for it to be infinite. The second law of thermodynamics essentially states that there is a limited amount of energy in the universe and that it is being used up. Now the universe could not have existed forever simply because there just isn't that much energy in the universe. If the universe was infinite then it wouldn't be here. If the universe wasn't created than it has to be infinite, which is an impossibility. Here is a similar reason that creation id true. This is called the cosmological argument: 1. Everything that had a beginning had a cause 2. The universe had a beginning 3. Therefore the universe had a cause. Now the first statement cannot be refuted. It's called the Law of Causality. It is a fundamental principle of science that everything that exists/had a beginning has a cause. The second statement is what I just proved in the first paragraph. A limited amount of energy proves that the universe had e beginning. Because those two statements are true the third statement must logically be true as well. We also know that the universe is expanding. This is proved by General Relativity. Now if the universe is expanding, and it is, it only makes sense that it started expanding at some point in time. If the universe was infinite it would be infinitely spread apart and it's quite clear that such is not the case.
