Is there scientific fact about the big bang theory ?

Answer 1

Hello Moon...

Yes there is, and it can be replicated (demonstrated) to anyone with an understanding of geometry or Trig through observation of various stars. If you make an observation
of a given star, it will appear at a certain angle up from the horizon. You must measure that angle very precisely. Now, wait about 6 hours and measure the angle to that star again very precisely. Those two angles give you the base angles of a triangle and the length of the base is the straight line between those two angles (some calculation required) which represents about 1/4 of the Earth's circumference (the Earth makes one full revolution in 24 hours , 6 hours/24 hours = 1/4). So then you use geometry to find the altitude of the triangle formed.

The altitude of the triangle is the distance to the star.

Now if you repeat this same proceedure 6 months from now, you will find that the distance is slightly larger. Pick any star you desire for this test, except the Sun.

What this means that all objects in space are moving. And, if you were to plot the directions of movement, you would find that objects in space are moving away from each other and away from some central point in space. This is a bit harder to do and requires spherical geometry to accomplish. However, that being said, if all objets in space are moving away from some central point, using math, we could reverse that process and calculate the trajectory of five, ten, or a hundred space objects and determine some particular point in space where they all must have come from. AND, that particular point in outer space would be the place that the Big Bang occurred. Believe me when I report to you that many scientists have done this repeatedly and are in general agreement with the theory. The only way a theory can become generally accepted in the scientific community is if the mathematic principles and calculations can be reproduced by someone else and yield the same results.

Okay?

Cheers,

Answer 2

The Big Bang is the scientific theory about the beginning of the universe that is accepted by almost all cosmologists. The theory says that the universe began by growing out from a single point about 13.7 billion years ago. The point was very small, dense, and hot. All space, time, and matter was created when the point got bigger.

The Big Bang theory is also supported by the distribution of light chemical elements and the cosmic microwave background radiation (very low-level radiation) in the universe.

Answer 3

There is a popular theory referred to as the 'Big Bang' theory. It tries to explain the existence of the universe in an evolutionary manner having an initial beginning with an immense explosion of some gases or solid mass. There has never really been any solid evidence for this idea of 'something out of nothing' concept. Nor for that matter, the evolutionary theory itself.
In fact, scientists have main 3 reasons for the formation of the big bang. But, there are no strong scientific fact to procve big bang.

Answer 4

The big bang theory is just that a theory.
The cosmic background radiation is not proof,it is based on an assumption that may not be true.
The universe likely started as a single,quantum space-time pulse of minimum size and duration.
The pulse was such that it could not be divided smaller and still exist.
The pulse continued cubing the essence of the entity.
It exploded outward,accelerating for one-thirty billionth of a second at which time the radial velocity reached the speed of light and the acceleration stopped.
At this time there was a 2 cm in diameter entity expanding radially at the speed of light.
It contained no matter,no gravity,no electro magnetism and no strong or weak forces.
It's temperature was absolute zero but it contained all the ingredients necessary to evolve into the universe we see today.

Answer 5

It is possible that some people are confusing the Big Bang Theory with contemporary theories of evolution. They are not connected, and they do not each depend on the other's existence. It is understandable that there is a connection at least as far as providing long enough time-frames to explain the expansion of the universe as we know it and to explain origin-of-life and evolutionary processes. Physicists pondering the beginnings of the universe do not have as their mission or priority to verify or accommodate life origins or evolutionist theories. In fact, many physicists consider biological sciences to be 'soft' sciences at best. Often, different scientific disciplines disagree with one another significantly. This almost always leads to spectacular and useful discoveries.

Answer 6

Yes, of course. Just as physics helps us to predict where the stars and planets will be in the future, so we can "run back" time according to the physical laws, until a fraction of a second after the supposed "big bang". So we know for example that the original universe was incredibly concentrated. But at some point - estimated to be a small fraction of a second after the big bang, when everything was *incredibly* concentrated, our knowledge of the physics pertaining at the time breaks down.

Answer 7

Not exactly fact, but there are Reasons.
They are like this:
Why we are getting Cosmic background radiation,
Why the universe is expanding,
Why is matter spread unequally in space
etc
This Leads to the possibility of big bang. There is not a scientific fact... This is a virtual theory based on real reasons.
This is globally accepted theory.

Answer 8

There are observed things that fit with the Big Bang theory,
these include,
the 4k background radiation,
the ratio of the primal elements H, He and their isotopes.

Answer 9

Yes, it has been proven in a number of ways. The most obvious, is the cosmic background radiation.
It has also been proven through simulation, modeling, the observation of red-shift, observation of distant/younger galaxies, and numerous other ways.

Answer 10

no, there is no proof to say that the universe is created by means of a big bang... but they say that the meteroids are results of that bang, also the planets are once meteoroids that have developed, that is according to the theory
