Survivors of shuttle Columbia

Although hardly believe in the accident suffered by the Space Shuttle Columbia in 2003 there were survivors.

A report released by scientists at the Ames Research Center of NASA has confirmed. This is about nematodes-Caenorhabditis elegans, tiny worms 1 mm in length travelling in an aluminum capsule as part of an experiment whose objective was to study their growth and reproduction in space.

Apparently, while the shuttle disintegrated in the atmosphere during its return trip, animals left dismissed from the ship and hit against the Earth with a force 2,295 times that of Earth gravity.

Unfortunately, the astronauts perished. The discovery demonstrates that small life forms could survive re-entry into our atmosphere.

Possible caves in planet Mars

Scientific that study the images of the ship Odyssey of NASA they have detected what you/they seem to be 7 caves in the surface of Mars.

This notice has just been announced in BBC News. The scientists have reached this conclusion due to the vertical reflection of the solar light in the flanks of the volcano Arsia Mons that indicate the appearance of cavities in the surface. The particulars of the discovery showed up in the Conference of Lunar and Planetary Sciences in Houston, Texas. Translated of the notice:

The authors say that the possible discovery of caves in the Red Planet is important. The caves could be the natural only structures able to protect primitive forms of life of micrometoros, radiation UV, solar ionospheric storms and particles high-energy that bombard the surface of the planet. The entries of these caves have between 100 and 252 width meters. Since in most one cannot observe the bottom, minimum depths are only known, from among 73 and 96 meters under the surface. However, you are calculated that the caves would have a perpendicular depth of up to 130 meters or more.

The measured temperatures as much in the surface as inside the supposed caves provide bigger information in this respect:

The data of temperature THEMIS backups this idea. During the day, one of the caves (to the one that "Annie" has called you you/he/she is warmer than the other and colder that the exposed areas to the solar light. The night temperature is warmer than in almost any other field. Glen Cushing, co-author and scientific of USGS in Flagstaff, Arizona, said that this is exactly what should happen if this structure was a cave. "Anything eats this you had been seen before in Mars", you said.

The scientists refer to the probable caves like the "seven sisters", to those that have allocated names to distinguish them: Dena, Chloe, Wendy, Annie, Abbey, Nicki and Jeanne.
This is at the moment the available information. In a future I will upgrade this entry. Meanwhile, they can observe the surface of the volcano Arsia Mons in Google Mars, or in the web page of the system THEMIS.

A SuperPC will allow to hear the sound of the black holes

Can somebody imagine the sound of a black hole? Gobbling and gobbling titanic quantities of matter and energy. Because that is what you/they have intended some physiques of the University of Siracusa, designing a superordenador that he/she will be able to detect and to identify the celestial sounds coming from the black holes.

This SuperPC has been baptized as SUGAR (YOUR Gravity and Relativity Cluster) and very soon he/she will begin to receive big quantities of data coming from Caltech. These data have been picked up during the last two years by the Observatory of Waves Gravitations (I TIE)

The assembling of SUGAR has been carried out by a group of physiques belonging to the I TIE, a world initiative that are about detecting waves gravitacionales. These waves gravitacionales are produced by violent events in the distant universe, as the collision of black holes or the explosion of supernovas. These waves spread for the universe to the speed of the light.

The construction of the detectors TIES you were ended in 2005, and they were installed in Hanford, Washington, and Livingston, in the state of Lousiana. After being finished, with an investment of 365 million dollars, they have been two years sampling them scientifically, and you are now when the analysis of the obtained data will begin.

You are expected that as much the superordenador as the high speed network are working throughout this month. Once the data are transferred to the University of Siracusa, the physiques will be able to begin to "hear" this cosmic" "symphony.

Will you be Replaced the Time by Another Space Dimension?

If the cosmos was that bare, when writing it we would putrefy lost book credit our time. But we make a bet and we continue writing, since we have only rasped the surface of the general purposes laws of the physics; the universe can be many things except bare. You can, in fact, book credit something in this madwoman devises of the nature of the universe that give a draft, being the fundamental time become another dimension of the space.

An idea like this falls outside of the domain of the conventional pansy, and inside the domains of the "mundobranas", a vision that encapsulate the universe of four dimensions that we know and you hug to interlaced supercuerdas through the same one.

The branas theory is a strange idea. To summarize, a brana ("membrane" abbreviation) can you turn like a sheet floating in a fifth dimension. As we can only experience a three-dimensional space throughout a dimension of the time (space-time of four dimensions, also well-known as universe Lorentziano), we cannot understand how this fifth dimension would be, but fortunately we have mathematics that you/they help us. The mathematicians can use them to describe as many dimensions as you are wanted. You come well, since the branas describes the cumulative goods of the "strings" that are interleaved throughout many dimensions and the forces that interact to create the universe that we observe in our boring space of three dimensions.

In accordance with the "mundobrana" vision, our cosmos of four dimensions in fact can be absorbed inside a multidimensional universe; our cosmic version only uses four of these possible dimensions.

The theorists that contemplate the mundobranas, as Marc Mars, of the University of Salamanca in Spain, believes now that they have tripped literally with an implication that would putrefy, to stop the cosmologists in your road. The dimension of the time soon could disappear to be replaced by a fourth dimension of the space. Our family universe Lorentziano could become Euclidean (that is to say, four space dimensions, without time) and Mars believes that the tests for this change can be exactly before our noses.

The expansion of the universe that are observed (discovered by Edwin Hubble in 1925) can, in fact, to be a symptom of a brana of changing" "signature. If our brana is mutando of temporary to space, the observers of the universe Lorentziano should observe an universe in accelerated expansion, exactly what we observe at the present time.

Mars enters in particulars on this theory that can explain this expansion every bigger time, while you maintain the physical features of the cosmos that we observe today, without supposing any form of dark matter or dark energy as responsible.

You are doubtful that we can perceive a cosmos at some time without time, and what would happen to the universe that pass to space is beyond our understanding. For that that, you enjoy your four dimensions while they last, the time soon could finish.

They detect what could be the print of another universe

An anomalous asymmetry in the cosmos opens a new investigation line.

American cosmologists have detected what you/they could be the prints of another universe that I collide soon after with ours of Big Bang. These investigators point out that the existence of other universes could be demonstrated thanks to the measurement of the background radiation of microwaves, since, if in the start of our universe, this had colisionado with other universes, hypothetically such a shock would be registered in the distribution of this radiation. Up to now nobody has tried to search this abnormality, but the authors of this studio have found an anomalous attractive asymmetry at least in the cosmos that, although they don't dare to affirm that it is about the print of another universe, they consider that this hypothesis can be the beginning of a long investigation project.


If other universes exist apart from ours, these could be detectables, they predict scientific in a new studio whose results have been published in the magazine Physical Review D. In this studio, Matthew C. Johnson and their accessories, Anthony Aguirre and Assaf Shomer, of the university of California in Santa Cruz, explains that they have evaluated the possibility that some goods observables or "trademarks" distinguibles that other universes had left in ours exist, due to collisions among them happened in the time in that our universe was even very recent.

The idea that other universes exist it is disputed in the current cosmology. If they really existed, the most probable thing is that they are not perceptible and it would be very difficult to sample their existence. What contributes the new studio is the hypothesis that, if they really existed other universes that colisionaron with ours, hypothetically we would putrefy today to detect their appearance, what constitutes a momentous discovery in the authors' of this studio opinion.

At the same time, these investigators recognize that the consequences of that eventual collision among universes continue being an open issue, since, although it is considered that if there was collision among universes both they would have been destroyed, what these scientists offer is a new approach.

Johnson has declared in this respect to the magazine World Science that is still to define what type of sequels it would be necessary to search to confirm the shock among the universes. Some physical theories point out that other universes really exist, called universes bubble and that each one of them has their own features and even securities different from the physical constants.

To demonstrate the transmultiversalidad

After the idea of the universes bubble it underlies the hypothesis that, seemingly, the whole space contains energy, the call energy of the hole, that is a background energy of purely quantum origin and responsible for physical measurable goods, as the effect Cashmere (it forces physics exercised among separate objects due to the resonance of the energy fields in the space among the objects).

Some cosmologists have offered that, if they occur certain circumstances, this energy can grow in an explosive way giving place to a new universe .como it happened with ours -. This could be happening continually, generating many universes that would coexist with the one that we know in the same way that the bubbles coexist in a foamy bathroom.

To analyze the radiation of the cosmic bottom

But how to know it? Johnson and their colleagues believe that any encounter or collision among the universes goods that would spread in both addresses would have taken place. This goods maybe left prints in the form of expelled material that you/they could affect to the distribution of the matter in each affected universe.

If a collision type had happened this way recently, from the temporary perspective of our universe, it would be undetectable since the universe is too extensive as so that it is notably affected. However, if the facts happened a long time ago, that is to say, when the universe was even very petty, the trademark could be even visible when having been expanded.

When the universe measured on or about less than a thousandth part of what measures currently, it is believed that it suffered a transformation. As it was expanding, he/she cooled down enough as so that they were formed the atoms. Then he/she became transparent.

Before this, the universe had consisted on a consistent fog with petty variances of density in diverse points. The densest parts continued increasing and when uniting they gave place to the galaxies.

Pending investigations

But this fog is even visible because we receive many of the light waves that took place in that moment in her now and they are observables in the form of a weak splendor that fills universe completely.

These waves have been named background radiation of microwaves that is a form of electromagnetic radiation considered by many cosmologists like the main test of the cosmological pattern of Big Bang that gave place to the universe. This radiation is considered the edge of our well-known universe also.

The astronomers outline that a collision among universes would putrefy generated book credit a standard that would have reordered the fluctuations of density in these circumstances and that, if it could register this reordering, he/she would appear as an area of symmetrical abnormality.

Up to now nobody has tried to search this abnormality, but the authors of this studio have found an anomalous attractive asymmetry at least in the cosmos that, although they don't dare to affirm that it is about the print of another universe, they consider that this hypothesis can be the beginning of a long investigation project.

The case is that the variances of temperature in the cosmic bottom of microwaves are believed that they reflect the variances of density in the primitive universe, but they would be still to make numerous investigations to be able to arrive to an answer.
