Big Bang Theory Fifteen billion years ago‚ give or take five billion years‚ the entirety of our universe was compressed into the confines of an atomic nucleus. Known as a singularity‚ this is the moment before creation when space and time did not exist. According to the prevailing cosmological models that explain our universe‚ an ineffable explosion‚ trillions of degrees in temperature on any measurement scale‚ that was infinitely dense‚ created not on fundamental subatomic particles and thus

It appears more and more likely that homo sapiens live in a multiverse. Could the massive universe that people live in be just one of countless … Would it be viable that there’s a parallel universe somewhere out there with another version of an individual ‚ where everything happened exactly as it did in this one ‚ except one tiny thing was done differently ‚ and subsequently had a life turn out utterly diverse as a result? It’s an astonishing concept: that there’s a whole new dimension created for

THe Pillars of the Big bang theory THE 3 PILLARS OF THE BIG BANG THEORY In the beginning there was nothing-no time to describe ‘when’ or no space to fill matter in. From this void sprung our universe when time and space came into existence as one entity. Despite its name the big bang theory isn’t really a theory about a bang at all. It is really only a theory about the aftermath of a bang (Allen Guth). The Big Bang theory is widely accepted by modern scientists‚ some however still doubt

Dark energy what is it? Dark energy is a unknown energy said to take up 70 percent of the universe. The energy is a repulsive gravitational effect that is causing the universe to accelerate out-ward. No one knows exactly what dark energy is or where it comes from. Dark Energy is a new idea. Little is known about dark energy‚ yet it takes up a huge amount if the universe. Scientist were able to show the universe was expanding at an accelerated rate by measuring the red-shift of an object by comparing

theory is perhaps the greatest discovery of all time. The Big Bang is a cosmological model that explains how the universe came to be and is based on known and well-tested laws of physics. However‚ the Big Bang theory does not explain why the universe was created. Three particular observations led scientists to believe in the standard hot Big Bang model: The expansion of the universe‚ the cosmic background of radiation and the abundance of light elements. Before these discoveries were made‚ the

the age an origin of our universe? The issue to be discussed in the following paper is the 3 theories of how the universe started‚ the Doppler Effect‚ the age of the universe‚ the origin of the universe‚ red shift/blue shift and dark matter/dark energy. The Doppler Effect is a change in frequency and wave length of a wave. It’s caused by the change in distance between the thing creating the wave and whatever it’s measuring‚ seeing and hearing the wave. The universe was created over 14 billion

was their first target‚ Sandage chose Messier 3‚ located in the northern constellation Canes Venatici‚ for his thesis. They discovered that the cluster ages were at least 3 billion years old‚ which can be used as an indicator for the age of the universe. This indicator was more consistent with geological time estimates for the earth’s age than the 1.8 billion derived through Hubble’s expansion value‚ as there is geological evidence on earth that suggests the earth is older than 1.8 billion years

exists has an explanation for its presence in the universe‚ the universe exists and therefore must have a creator. An argument could be made to say that God is the answer for who created the universe. Many will say that the existence of the universe does not inherently mean that the creator is God. Although this raises a crucial question‚ what is God if not the creator of the universe? The definition in many dictionaries is “the creator of the universe”. Just by the definition‚

scientific theories that attempt to explain how our universe began. The information contained below will attempt to outline the Big Bang theory and the Cosmological Argument. In 1929 an astronomer named Edwin Hubble discovered that the universe is expanding the same in all directions and from this conceived the Big Bang Theory (Craig 30). Everything in the universe is expanding outward. This implies that at some point in the past the entire known universe was contracted down to a single mathematical point
