Big bang hypothesis

Big Bang - wikipedia

But if the big Bang was an explosion In a conventional explosion, material expands out from a central point. . A short moment after the explosion starts, the centre will be the hottest point. . Later there will be a spherical shell of material expanding away from the centre until gravity brings it back down to earth. . The big Bang—as far as we understand it—was not an explosion like that at all. . It was an explosion of space, not an explosion in space. . According to the standard models there was no space and time before the big Bang. . There was not even a "before" to speak. . so, the big Bang was very different from any explosion we are accustomed to and it does not need to have a central point.

It is better to regard points off the surface as not being part of the universe at all. . As gauss discovered at the beginning of the 19th century, properties of space such as curvature can be described in terms of intrinsic quantities that can be measured without needing for to think about what it is curving. . so space can be curved without there being any other dimensions "outside". Gauss even tried to determine the curvature of space by measuring the angles of a large triangle between three hill tops. When thinking about the balloon analogy you must remember that. The 2-dimensional surface of the balloon is analogous to the 3 dimensions of space. The 3-dimensional space in which the balloon is embedded is not analogous to any higher dimensional physical space. The centre of the balloon does not correspond to anything physical. The universe may be finite in size and growing like the surface of an expanding balloon, but it could also be infinite. Galaxies move apart like points on the expanding balloon, but the galaxies themselves do not expand because they are gravitationally bound.

hoyle wrote "My non-mathematical friends often tell me that they find it difficult to picture this expansion. . Short of using a lot of mathematics I cannot do better than use the make analogy of a balloon with a large number of dots marked on its surface. . If the balloon is blown up the distances between the dots increase in the same way as the distances between the galaxies." The balloon analogy is very good but needs to be understood properly—otherwise it can cause more confusion. . As hoyle said, "There are several important respects in which it is definitely misleading." It is important to appreciate that three-dimensional space is to be compared with the two-dimensional surface of the balloon. . The surface is homogeneous with no point that should be picked out as the centre. . The centre of the balloon itself is not on the surface, and should not be thought of as the centre of the universe. . If it helps, you can think of the radial direction in the balloon as time. . This was what hoyle suggested, but it can also be confusing. .

What Is the big Bang Theory?

The alien will see it receding at 10,000 km/s:, from A 0 km/s 10,000 km/s 20,000 km/s. From b -10,000 km/s 0 km/s 10,000 km/s. So from the point of view of the alien. B, everything is expanding away from it, whichever direction it looks in, just the same as it does for. The famous Balloon Analogy, a good way to help visualise the expanding universe is to compare space with the surface of an expanding balloon. . This analogy was used by Arthur Eddington as early as 1933 in his book, the Expanding Universe. . It was also used by Fred hoyle in the 1960 edition of his popular book. The nature paperless of the Universe. .

The universe is not expanding out from a centre into space; rather, the whole universe is expanding and it is doing so equally at all places, as far as we can tell. In 1929 Edwin Hubble announced that he had measured the speed of galaxies at different distances from us, and had discovered that the farther they were, the faster they were receding. . This might suggest that we are at the centre of the expanding universe, but in fact if the universe is expanding uniformly according to hubble's law, then it will appear to do so from any vantage point. If we see a galaxy, b receding from us at 10,000 km/s, an alien in galaxy. B will see our galaxy, a receding from it at 10,000 km/s in the opposite direction. . Another galaxy, c twice as far away in the same direction. B will be seen by us as receding at 20,000 km/s. .

In the following diagram, quadrant a is the state of the universe some time before that of quadrant. Source: University of Virginia, in quadrants c and d, the vantage point of an observer is marked with a white. By laying a over b and centering them both on the same vantage point, we see how it appears that that point is the center of the universe. But shift that vantage point to another star, and it becomes clear that no matter where one is looking from, essay he will always appear to be at the universes center. Where is the centre of the universe?

Physics faq, copyright, original essay by Philip Gibbs 1997. There is no centre of the universe! . According to the standard theories of cosmology, the universe started with a "Big Bang" about 14 thousand million years ago and has been expanding ever since. . Yet there is no centre to the expansion; it is the same everywhere. . The big Bang should not be visualised as an ordinary explosion. .

While the dots on the balloon will stretch, due to gravity the universes matter will not. But to make things even more confusing, lightwaves certainly will. And finally, the balloon gives the impression that the universe is growing within an empty space, but the big Bang was the creation of space itself. Consequently, there is no edge to the universe. There is no center of the universe.

Source: Regenerating Universe Theory, in 1929, hubble observed that not only were many of the fuzzy nebulae among the stars actually huge, distant galaxies, but almost all of them were receding from Earth at a rate proportional to their distance. In every direction, galaxies twice as far as others were moving away twice as fast. But that would mean that the really, really distant objects would be moving faster than the speed of light, which Einstein proved impossible. The only viable solution was that the space between objects was expanding uniformly at all points throughout the universe. That would mean that the universe had no center, but instead filled out like a tv screen when turned. Though initially counterintuitive, the universes lack of center is one of the easiest ways to understand the uniformity of the expansion of space.

This is not far off; there was a lot of heat and a lot of outward motion. But the big Bang was not an explosion in space, it was the creation of space. After a decade of arguing summary against it, Fred hoyle popularized the balloon analogy for what actually occurred during the big Bang. There are a lot of flaws in this analogy, but short of a few PhDs in mathematics its a fairly adequate representation of the real thing. Imagine a polka-dot balloon being blown. As more air enters into the balloon, the space between the dots gets bigger in the same way the space between galaxies does. In other words, the bigger the balloon gets, the greater the distance between the dots. The main issue with this visual is that its a three-dimensional rendering of a two-dimensional example of a three-dimensional phenomena.

Dicomot ti " ". Ex: several hypotheses for global warming have been suggested. The hypothesis of the big bang is one way to explain the beginning of the universe. Source: nasa, the name was initially meant to be a dismissal. The term big bang was coined live on bbc radio in 1949 by Fred hoyle, a scientific opponent to what was then the fringe primeval atom hypothesis proposed by catholic priest georges Lemaitre. Hoyles equally alliterative steady State theory had been accepted by everyone from Einstein to hubble, but contradicting discoveries in the 1920s had slowly started to dismantle the erstwhile pillar of astronomical thought. Hoyle dismissed this big bang idea since it suggested that the universe had a beginning, implying to hoyle that there was some sort of a creator. But both his straw man and his assumption and fundamentally misrepresents what the big Bang actually proposes. Dont think explosion, think expansion, source: Physics gg, alright, so maybe big bang is a bad name for what actually happened, but a ton of hot stuff accelerating in all directions sure sounds like an explosion.
