Uluru what if . . . – mechanix illustrated gas bloating after eating

It is said that science advances one funeral at a time. physics electricity and magnetism study guide Or, as Max Planck put it, “A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it.” In other words, “settled science” can be remarkably stubborn—even in the face of new evidence. Unthwarted, new theories—some more radical than others—continue to be promulgated, and they abound. In this new series, we offer for your consideration a sampling of such assumption-smashing theories.

Take, for example, some new thinking about Uluru. For over a century, geologists have affirmed that the strange rock sitting in the middle of the Australian outback is the result of a sandstone plate that, over an immense span of time, was uplifted vertically to form its present, monolithic, appearance. But, could it have had a more sudden, astronomical, origin? Could Uluru (formally known as Ayers Rock) actually have come from outer space? Could it be the nucleus of a comet that fell to Earth many millions of years ago when the surface of central Australia was covered by an inland sea?

First, and perhaps most importantly, Uluru is the right size. electricity shock in the body Most cometary nuclei range in size from approximately I km to around 3 kms. Uluru being 3.6 km long by 1.9km wide and approximately 10 km in circumference is, surprisingly, just the right size for a cometary nucleus. Like an iceberg, most of the mass of this monolith is buried beneath the surface and is thought to extend some 2.5 km.

Another important clue is evidence of surface melting. The outer skin of the rock does show evidence of melting in places, as would be expected being heated to several thousand degrees as it plunged through the Earth’s atmosphere. electricity news australia We can safely discount the possibility that this was caused by melting in the heat of Australian outback! (See photos 1 and 2)

As the comet approached the inner Solar System, solar heating would cause ice locked into the honeycomb interior near the surface to melt, expand, and be forced to escape via the strings of vent holes running parallel across the surface. Most of the vent holes are now filled in due to sediment build-up over millions of years but, also, probably by melting of the outer skin when the object plunged through the Earth’s atmosphere.

Could a space rock with the honeycomb-like structure of Uluru (which is porous and relatively light) survive a heated passage through the Earth’s atmosphere? Most astronomers would probably say no, because it is believed cometary nuclei are just a loosely bound conglomeration of rocks and ice and this would simply fall apart and disintegrate due to extreme entry heating. However, if the nucleus of the comet had a honeycomb-like structure, as we find on Uluru, and had ice trapped deep inside, It might very well survive the brief (two or three minutes) passage to Earth. As anyone knows, deep frozen ice is an extremely hard and durable substance. Furthermore, iron particles in the sandstone composition of the rock might act, upon melting, as a kind of natural heat shield preserving the frozen water ice inside.

Why hasn’t Uluru been viewed from an astronomical perspective before? The answer probably lies with three reasons: (1) Aerial and satellite imagery wasn’t largely available until recently, (2) Images of cometary nuclei certainly haven’t been available until very recently, and (3) it is simply the entrenched opinion of geologists that the rock was uplifted and folded almost vertically from an underground sandstone plate. In short, until recently, we’ve simply lacked any astronomical references with which to compare it. Now, thanks to close-up images of asteroids and cometary nuclei, we do.

If this were the case, the only way it could have reached Earth would be by way of ejection from the surface of Mars following a very energetic impact with an asteroid. gas out Mars has one of the largest impact craters in the solar system, the Hellas crater in the southern part of the planet (see photo 15). This massive crater is 2,300 kms wide and some 7kms deep. To make a crater this large, it is estimated the impactor must have been at least 100 kms in size. It is also noteworthy that a part of the crater floor is found to have a curious honeycomb-like terrain—similar to what appears to be the structural composition of Uluru. cheapest gas in texas Could this huge impact have hit a sandstone cliff, for example, and ejected kilometre-sized chunks of rock into space? If it did, and the porous rocks contained water ice trapped in the interior, then we have all the ingredients for the making of a comet!

In this scenario, the rock (Uluru) is ejected from the surface of Mars by the asteroid impact and enters an elliptical orbit around the inner solar system. electricity schoolhouse rock As the rock periodically neared the sun, trapped water ice in the interior would melt and be forced out of the nucleus via sink holes in the surface to form the evaporation trails we see as the comet’s tail. As observed earlier, we see evidence of these sink holes on Uluru.

Is there any way to prove whether or not Uluru is the extinct nucleus of a comet? Short of excavating the 2.5 kilometres underneath it to see if the parallel strings of vents and sink holes continue all the way around the object, it may be difficult to prove. Perhaps another possibility might be to drill to the centre and take samples of core material to see if there is any evidence of fossilised extraterrestrial organisms present. Both these options are unlikely to be permitted. gas bubble retinal detachment Either way, when the observations outlined here are compared to what we today know about comets and their nuclei, it might be better to assume Uluru came from outer space rather than out of the ground.
