The gravity of a black hole is so strong that nothing not even light can escape it-How then did all matter in the universe escape the singularity of the big bang-an infinitesmal point?

The matter didn't have much choice -- the space that is our Universe began to expand, driven by something greater than gravity, and took the matter within it along for the "ride."
At present, scientists do not know why space began to expand, any more than they understand why there is lightning in the sky. They are working on both questions.

Why the universe keep on shrinking?
In the beginning there was nothing then the big bang happened. The universe expanded at an incredible rate before beginning to cool down. Then matter formed. Eventually the expansion will stop and the combined gravity of the universe will draw the universe back to nothing causing it to "shrink". Although this is one theory there is another that says the universe will never stop expanding due to a substance called dark matter (the opposite of gravity) pushing it ever outwards.
If the Big Bang exploded matter out Was the dark container of space always there to receive the matter or was the vacuum of dark empty space created as the matter expanded into it?
That's a very good question, and the truthful answer is "Nobody knows for sure".Many have said, however, that the universe was very likely created as the energy and mass expanded. So the "dark, empty void" that is the fabric of space was actually created as the energy from the Big Bang moved outwards. Beyond the edges of the universe is... well, nothing. Perhaps another universe, although several have proposed the "no edges" idea. That is, much like a video game, if you pass through the "edge" of the universe on one side, you wind up on the other side. In other words, if you keep moving in a straight line across the universe, you will eventually get back to your own starting position, but you would never know that you had deviated from your path (because, in fact, you didn't). Think Pac-Man.That's the best theory we can present at the current time.One on the best books elaborating on the Big Bang Theory in an understandable format is Bill Bryson's "A Short History Of Nearly Everything". It explains that space was never there, but actually was created as the singularity that contained all the matter in the universe exploded and expanded. This singularity was so small that it had LITERALLY no dimensions, and took up absolutely no space, yet contained untold billions of tons of material all compacted together. As this singularity expanded, it expanded at just the right speed as to create all the forces in the universe, like gravity, inertia, and all those. If it expanded faster, the universe would have collapsed in on itself long ago, and the creation material would have been so far spread that nothing would have been made. Had it expanded slower, then everything would still be too compacted and close together, so that nothing would've been created. There is also a theory that, at some point, the universe will not be able to expand any further, and the theory also includes that the universe is still expanding. But at any rate, the theory goes that the universe will reach a point where it cannot expand any farther, and then it will slowly creep back into a singularity. And the process will start over again. This, however, cannot be proven, and is only one of several theories.Scientists continue to investigate the conditions that created the early universe.
Difference between geo- and helio-centric model?
Geocentric is that the earth is the center of the universe and heliocentric is the sun is the center of the universe. can it be nothing.
What happens to gravity as you move further south in the Southern hemisphere?
Nothing happens to gravity. It remains the same as it is everywhere else on earth.
Who can beat up Jason Bourne?
Nothing, that we know of in this universe can kill jason bourne
How does the periodic table relate to the universe?
The universe was, as the science claimed, created from nothing which is called the singularity. The "nothing" was dipped in Higgs field and a mass then created. From the mass, the universe was created.
What colour was the Singularity that gave rise to the Universe?
Undefined. We have precisely ZERO information about the singularity; in fact, the word "singularity" implies that we CANNOT know anything about it. The laws of physics, as we understand them, do not work in a singularity, so nothing can be said about it. If it helps you to visualize it, think of it as a black point in a dark universe.
According to astronomers the age of the universe is estimated to be?
According to the standard theory, our universe came into existence as a "singularity" around 13.7 billion years ago. The age of the Earth is 4.54 ± 0.05 billion years.According to calculations, time and space had a finite beginning that corresponded to the origin of matter and energy. The singularity didn't appear in space; rather, space began inside of the singularity. Prior to the singularity, nothing existed, not space, time, matter or energy - just nothing.
What is a back hole in space?
When a star of 3 solar masses or more burns up its nuclear fuel, it collapses on itself creating a singularity. This singularity has such a strong gravity that nothing, not even light can escape.
When did gravity occur?
Gravity is one of the 4 fundamental forces of the universe. Without gravity, nothing would exist. Nothing made gravity, and nothing can destroy gravity. So one answer to this intriguing question is: Before the first speck of matter.
Is there gravity on other galaxies?
In other you mean, and yes. There is gravity every nano meter of the whole universe, nothing is away from gravity, gravity is everywhere.
What was there before bag bang?
That is unknown. There are many different ideas. Some say there was nothing, some say there was a singularity with all the mass of the universe, ans still others say they was another universe.
What is a possible result of a supernova - the core of the star collapses to a single point and gravity is so strong that nothing can escape?
You are describing a black hole, or singularity.
How did the universe evolve?
13.75 billion years ago, the Universe started out in an extremely small, hot, and dense state known as a singularity. This singularity was nothing but energy. Then, in the Big Bang event, this singularity rapidly expanded to trillions of times its original size in less than a second. The Universe rapidly cooled from trillions to millions of degrees, and energy began to condense into subatomic particles called quarks and gluons. Protons, neutrons and electrons formed, creating the first atoms. Hydrogen was the first element, and continues to be the most abundant. At first, the Universe was opaque. When it cooled down enough photons could escape and the Universe became transparent. Millions of years later, gravity pulled together clouds of hydrogen to form the first stars. Stars synthesized all the heavier elements through nuclear fusion, such as helium, carbon, and oxygen. Furthermore, gravity pulled stars together into galaxies. It would take thousands to millions of years for the Universe to cool to the temperature it is today, and it continues to expand today.
What happen to matter when it enters a black hole?
It is first stretched then pressurised. so if a human was to enter a black hole, you would first be turned into a spaghetti-looking thing then you will be pressureised. too much pressure on any human will make them explode.
Which is not an example of gravity?
Nothing, gravity affects everything in the universe every yocto-second. You cant come up with a non example. Even anti-gravity is an example of gravity since your just reversing the pull of gravity to a push.
What do most scientists believe existed before the incident known as big bang?
Most scientists believe that an infinite dense singularity existed before the incident known as the Big Bang.
