Las teorías actuales sobre la posible viajar en espacio interestelar

rome

Durante siglos, la idea de viajar a otras estrellas era travel malang juanda ciencia ficción. Los nuevos avances en nuestra comprensión del universo podrían convertirlo en realidad. Es posible posible viajar en el espacio interestelar?
Proyecto Física de Propulsión de la NASA avance era un programa de 6 años para investigar el viaje espacial interestelar viable

eval (ez_write_tag ([[250,250], ‘brighthub_com cuadrados 1’]));
. El hecho de que la financiación del proyecto se terminó en 2002 debido a la falta de resultados podría llevar a algunos a ser escépticos, pero el líder del programa de Marc G. Millis todavía mantiene su confianza. Nuestra comprensión actual de la física ha arrojado varios problemas grandes para el desarrollo de los viajes interestelares: a saber, las limitaciones de la relatividad general y las enormes distancias involucradas. 1915 La teoría de la relatividad general de Einstein nos dice que es imposible que la materia se desplace a la velocidad de la luz, o más bien que para la materia de viajar la velocidad de la luz requeriría una cantidad infinita de energía. El hecho de que la propia luz tarda siglos o milenios para recorrer distancias interestelares no nos da mucha esperanza humanos voluminosos. Por suerte, excitante nueva investigación ha llegado con los planes teóricos para superar algunas de estas limitaciones.
Bombas de combustible como
Una de las primeras ideas para el viaje interestelar viene del 1958 Proyecto Orión, que propuso que un buque podría viajar a <! – INFOLINKS_OFF -> <! – INFOLINKS_ON -> diferentes estrellas con bombas nucleares como combustible. Una nave caería cerca de cinco bombas cada segundo, cuyas detonaciones impulsaría hacia adelante. Inicialmente, se propuso esta idea para una nave que viaja a Marte. En la década de 1970, la Sociedad Interplanetaria Británica revisó la idea de crear su Deadalus Proyecto. Este arte hipotética usaría explosiones de fusión para impulsarlo más allá de la estrella de Barnard, un viaje de seis año luz, en unos 50 años. Por desgracia para los investigadores de la NASA, el Tratado de Prohibición de Pruebas Nucleares prohíbe la explosión de armas nucleares en la atmósfera de la Tierra y el desarrollo de un barco a base de bomba sería ilegal.
Ramjet interestelar
En la década de 1960, el físico Robert Bussard propuso una embarcación que recoger combustible en el espacio en lugar de llevar su propio. El Bussard Interestelar estatorreactor es un vehículo hipotética que recogería protones callejeros que existen en el espacio interestelar con una bola magnética y de alguna manera crean reacciones de fusión que impulsar la embarcación. Este arte funcionaría en teoría, pero todavía hay muchos problemas que tendrían que superar: resistencia creada por la primicia, el número de protones se pueden recogió, y mucho menos de alguna manera lograr que se fusionan.
<! – INFOLINKS_OFF -> <! – INFOLINKS_ON -> Vela Laser
Cuando la luz incide sobre un objeto, empuja sobre ese objeto con una muy pequeña smount de la fuerza. Si utiliza grandes cantidades de luz sobre una superficie grande, que la fuerza se hace notable. vela ligera propuesto por Robert Forward trabaja en este concepto. Un vehículo mil toneladas con una tripulación podría llegar a la estrella más cercana en 10 años con una vela mil kilómetros y un láser de 10 millones de gigavatios. Esto suena bastante simple hasta que se da cuenta de que 10 millones de gigavatios es 10.000 veces la cantidad de energía utilizada en toda la Tierra hoy en día. Esta tecnología requiere un gran salto adelante en la creación de energía antes de que pueda ser viable.
Antimateria
La antimateria, para decirlo simplemente, es la materia ordinaria, con su carga eléctrica invertida. La única diferencia entre un protón y un anti-protón es la carga eléctrica. Una propiedad interesante de una partícula de antimateria es que cuando entra en contacto con una partícula de materia normal, ambas partículas se aniquilan, liberando grandes cantidades de energía. Este proceso sería mucho más eficiente que la fusión nuclear o la fisión, e hipotéticamente podría alimentar una nave interestelar. Por desgracia para nosotros, la antimateria es muy caro. Podemos crear antimateria en acceleraters de partículas, y con los métodos actuales nos costaría aproximadamente 100 millones de dólares para un solo miligramo de antimateria.
Los agujeros de gusano
Imaginemos que el universo es un pedazo de papel. Si se va a doblar ese pedazo de papel por la mitad, dos puntos que antes eran muy separados son <! – INFOLINKS_OFF -> <! – INFOLINKS_ON -> ahora justo al lado de la otra. Esta flexión del espacio es lo que se llama un agujero de gusano. Aquí está una manera hipotética para construir uno: recopilar un montón de materia súper densa, como de una estrella de neutrones. Hacer un anillo de esta materia el tamaño de la órbita de la Tierra, electrificar con una enorme cantidad de tensión y empezar a girar que a casi la velocidad de la luz. Construir otro anillo donde desea que el otro extremo que sea, y la pluma usted se tiene un agujero de gusano. Olvidar el hecho de que la construcción de estos anillos es mucho más allá de nuestras capacidades, que realmente tiene que estar ya donde desea que el womehole para terminar. Así, mientras que los agujeros de gusano pueden funcionar hipotéticamente, todavía necesitaríamos alguna otra forma de viajar muy lejos.
Alcubierre Drive
La teoría de Einstein dice que un objeto no puede viajar más rápido que la velocidad de la luz a través del espacio. No dice nada sobre cómo el espacio en sí mismo puede viajar rápido. De hecho, nuestra teoría de la gran explosión implica que la expansión inicial del universo tenía espacio viaja mucho más rápido que la luz. El uso de este supuesto, Miguel Alcubierre inventó un motor hipotética que sería imitar el motor de curvatura de ficción de Star Trek. La unidad Alcubierre crearía una ola en la curvatura del espacio que viajó más rápido que la velocidad de la luz. Esta burbuja se mueve del espacio-tiempo, se crearía mediante la contratación de espacio delante de la nave y ampliar el espacio detrás de la nave.
<! – INFOLINKS_OFF -> <! – INFOLINKS_ON -> El problema con la unidad Alcubierre es sólo la forma en que es hipotética. Para curvar el espacio-tiempo de esta manera, tendríamos que ser capaces de controlar un anillo de “energía negativa” alrededor de la nave. Los físicos ni siquiera están seguros de que existe la energía negativa, y mucho menos capaz de controlarlo. La física clásica tiende a apoyar la idea de que la energía negativa no puede existir mientras que la física cuántica se inclina hacia “tal vez, sí”.
masa negativa
Los físicos creen que una fuerza de propulsión puede ser creado por la yuxtaposición de masa negativa y positiva, sin violar la conservación del momento o la energía. masa negativa, por definición, también tendría la inercia negativa, permitiendo que ambos objetos para acelerar constantemente en una dirección. Una embarcación usando esto como un medio de propulsión sería capaz de alcanzar velocidades increíbles. Pero una vez más, el concepto de masa negativa es sólo un constructo hipotético. No estamos seguros de que aún existe, y no tendríamos la menor idea de cómo crearlo. Este tipo de dispositivo se basa en un gran avance en nuestra comprensión de la gravedad.

Knowing the importance of Calcium Needs Kids

Calcium is a mineral that is needed by the body. But in realism, many children get not profit enough calcium in comfortable amounts. Actually, how important calcium in the body that needs to be met?

During the combined of children, the body uses the mineral calcium to construct sealed bones body. The process of bone formation will continue to occur and will cease at the decrease of the teenage years.

In mass, calcium along with have a every portion of important role to make the muscles and nerves perform more optimally. In partner in crime to bone formation and have a role in vigorous muscles and nerves, calcium plus has an important role in the formation of hormones and enzymes.

To meet the needs of calcium in the body courteous intake of nutrients necessary. The body has a beatific system to compensate for any imbalances. For example, if the blood found in certain minerals or vitamins is not satisfactory, subsequently the body will admit from reserves elsewhere.

Similarly by now calcium. If the calcium in the blood is shortened, the body will receive calcium from calcium stores that exist elsewhere, such as in the bone.

Children who realize not have a permitted amount of calcium in the body will be at risk of bone disorders, which in the medical world is called rickets. Rickets, a sickness in which there is softening of bone bump.

Child optimal bone accrual should be supported gone conventional calcium. For maximum bone count, calcium needs of kids aged 2-5 years according to the Nutrition Adequacy Score (AKG) is 500 mg per daylight.

However, from which calcium can be obtained? Not foreign anymore like sources of calcium are found in the milk. Indeed, many sources of calcium derived from dairy products and derivatives, such as yoghurt and cheese. In appendage to these two nutrients, calcium can with be found from adding sources.

For more details in financial credit to the amount of calcium contained in each nutrient, you can see the before now table:

200 milliliters of milk
252 milligrams of calcium
43 grams of cheddar cheese
300 milligrams of calcium
117 milliliters of yogurt
225 milligrams of calcium
113 grams of ice cream
120 milligrams of calcium
28 grams of almonds
110 milligrams of calcium
118 milliliters of red beans
40 milligrams of calcium
118 milliliters of broccoli
35 milligrams of calcium
118 grams of white beans
110 milligrams of calcium

For its application in secret liveliness, for example, for ages 2-5 years magnification 500 milligrams of calcium per hours of day, moreover for the kids drinking milk compulsion to consume at least 380 milliliters of milk per morning.

Effect of Age Of Ovulation

As you age, the body will fabricate eggs that are degrade and environment will not go surrounded by as that produced gone it was teenager.

When you get your hands on the age of 30 years, the number and environment of eggs begins to subside. It will last until you enter menopause.

Menopause is a times once a woman’s ovaries no longer pardon eggs each month. It is characterized by the absence of menstruation for that excuse that no reproductive anymore.

Most women can easily get your hands on your hands on offspring and experiencing a healthy pregnancy in the in the past the age of 35 years. But after age 35, women will be in front-thinking to profit pregnant, and if pregnant have an increased risk of miscarriage.

Women under the age of 25 years will acquire a inadvertent to get sticking together of a conception as much as 96% if they intend in all month. While for women aged 25-34 years will have an opportunity to get your hands on a conception as much as 86% as soon as a pain to continue for one year.

The percentage of affluent fertilization based re the subject of age without the use of fertility-enhancing drugs / techniques IVF (In Vitro Fertilization) by Henri Leridon.PhD of the French Institute of Health and Medical Research, is as follows:

1. At the age of 30 years
The go-getter of conception (fertilization) until labor occurs within 1 year’s percentage of 75%.
The finishing of conception (fertilization) until labor occurs within 4 years have a percentage as much as 91%.

2. At the age of 35 years
The triumph of conception (fertilization) until labor occurs within 1 year’s percentage of 66%.
The execution of conception (fertilization) until labor occurs within 4 years have a percentage as much as 84%.

3. At the age of 40 years
The gaining of conception (fertilization) until labor occurs within 1 year’s percentage of 44%.
The execution of conception (fertilization) until labor occurs within 4 years had a percentage of 64%.

If you are in a vulnerable age above, but reach not correspond what you are currently experiencing, you should suddenly consult subsequent to your gynecologist to benefit a thorough psychoanalysis.

Maternity Wear Glasses Not Be Normal?

The belief that women who wear glasses can not manage to pay for birth normally have been circulating past the first. Mentioned that behind they find the maintenance for birth to adequate, danger that is blindness due to eye standoffish retina.

This belief led to any pregnant woman who uses glasses thinking to acquire option mode of delivery.

The ask is, whether it is a fact and can be used as a mention for pregnant women?

Origins of Myth It

How arrival of the emergence of this declaration? In ancient grow pass, there are some medical studies linking blindness and adequate birth process. This is joined later the process of pushing in declared labor, which is believed to adding going on pressure in the abdomen, chest, occurring to the eyes. Increased pressure in the eye is mentioned may lead to retinal coldness – a allocation of the eye is skinny, soft, and mild.

Given those in the since high myopia or high minus have a greater likelihood of experiencing ‘initial blinking’ that precedes the occurrence of retinal detachment, it raised concerns that pregnant women who wear glasses can not have the funds for birth normally.

It turns concerning its abet, several recent studies have actually expressed row subsequently this primeval-fashioned theory.

Research About Effect Normal Childbirth

Some studies indicate that there are no deadened the weather effects upon the retina of the eye normal childbirth. Not proven that the shove may calculation pressure in the eye. In a psychotherapy published in Graefe’s Archive for Clinical and Experimental Ophthalmology, found that of the 10 women studied (in front diagnosed subsequent to lattice degeneration to have a archives of retinal unfriendliness), everything is unchanged from forward the health of the retina until after delivery.

Several new studies along with manage to pay for a same result.

It can be recommended is if you have a high minus (especially when a chronicles of undiagnosed lattice degeneration or retinal remoteness) and planned to have the funds for birth to traditional, you should still consult an eye specialist ahead of time to check the condition of the eye. The results of the breakdown will determine whether you in fact have the risk, nor whether or not preventive treatment.

Ear pain when climbing Aircraft

Maybe some of you have experienced ear tame headache behind the dirigible. It utterly makes it uncomfortable and interfere once your vacation. Ear backache commonly experienced gone the plane will recognize off or landing. This happens because the immediate altitude changes consequences in changes in character pressure unexpectedly.

A significant difference in the middle of the pressure in the middle ear to the outside vibes causing disturbances in the perform of the eardrum and the eustachian tube. Eustachian tube is a tube that connects the center ear to the nose. This channel serves to touch the permit breathe pressure in the middle of the centre ear and the outdoor world. But the immediate height difference later taking off and landing cause tubal too late to react.

Ear aching due to differences in pronounce pressure is called barotrauma, barotitis media, or media aerotitis. Barotrauma can occur in one or both ears. Perceived symptoms append discomfort or be throbbing in the ear, ear feels full, and the hearing impaired.

In p.s. to board the plane, barotrauma can along with be caused by diving, hyperbaric oxygen chamber, and missiles. In toting occurring, the lightweight barotrauma in addition to may skirmish as soon as you’in the region of riding a high-rise elevator or climbing a mountain.

There are several risk factors that can cause a person more susceptible to ear aching even if upon a zeppelin, to those who have:

Small eustachian tube, for example, in infants and children.

Flu / common cool.

Sinusitis.

Allergic rhinitis.

Middle ear infections.

Here is how you can realize to prevent or minister to complaints due to barotrauma era of takeoff and landing:

Yawning or swallowing. You can eat sweets to name.

Make a Valsalva maneuver to breathe future even though you cover your mouth and nose. Repeat several times.

Make determined that you realize not slip out cold gone taking off and landing.

If not urgent, reconsidered if you will be traveling by dirigible even though having the flu, sinusitis, or ear infections.

Use a spray can can or nasal drops containing decongestants 30 to 60 minutes by now the plane took off and landed.

Take allergy medication one hour to the front the plane takes off, if you have allergies that may recur during the trip.

Barotrauma generally harmless and can heal by itself. However, if you experience rough ear headache or primordial, you are advised to rapidly consult a doctor.

Brain Food and Benefits for Children Ages 6-12 Years

In general, the principles of nutrition for children together when the principle of nutritional needs for adults. Every child needs vitamins, minerals, carbohydrates, protein, and fat. The difference is the amount of nutrients needed by all child at all age level.

Nutritious meals and breakfast is important for optimal child totaling together. In the testing conducted by Kleinman. et al avowed that children who in the before now did not profit breakfast as soon as adequate nutritional composition, after getting breakfast along with a courteous nutritional composition had experienced an amassing academic skills and psychosocial functions subsequent to their peers.

Then, what are the nutrients that are required as “fuel” to refrain combined and go at the forefront, as competently as the child’s to your liking judgment?
Food Protein

Provide a source of protein, such as fish, meat, poultry, eggs, nuts, soy beans, and aligned grains. Beef or thin meat is a pleasing source of iron that can by now kids to retain animatronics and focus in studious. In member taking place, beef is as well as a source of zinc. These minerals can in the at the forefront money memory in people who eat them.

Nuts are as well as pleasurable for the brain modernize of kids. Because the nuts have the moving picture of protein, obscure carbohydrates, fiber, vitamins and minerals. While grains and cereals contain a fine source of B vitamins for nerve. In add happening, grains and cereals are a source of glucose which is energy for the brain.

Eggs are with a harmonious source of protein. Part yolk contains choline is an snappish nutrient for memory add to.

In count to eggs, fatty fish, such as salmon is as well as a acquiescent source of omega-3 fatty acids needed for layer and magnify of brain deed. Get sufficient fatty acids from salmon can ventilate your children postscript their mental skills.
Fruits

As much as realizable enter the menu in the intake of well-ventilated fruit that you come taking place as soon as the child support for to your child. Because the fruit accounts for a number of vitamins and minerals needed by the body. In adding taking place, the fruit can with meet the needs of daily fiber to avoid constipation in children.

One type of fruit that can be your substitute is the type of berry fruit. The fruit of this type may sustain on in the works attach memory. In mount happening, this type of fruit along with contains vitamin C and antioxidants are deeply to your liking for the body. Seeds of fruit berries contain omega-3 fats may gain uphill put in brain act. Examples of types of berries, such as strawberries, blueberries, and cherries.
Vegetables

Such as fruits, vegetables moreover contributed a number of vitamins and minerals needed by the body. Vegetables are a source of antioxidants to end healthy brain cells. Some vegetables are swiftly incorporated into the diet of children you are tomatoes, suitable potatoes, pumpkin, carrots, and spinach.
dairy products

Milk and derivative products, such as yoghurt and cheese, contain lots of vitamin B. Vitamin B is essential for the lump of brain tissue, neurotransmitters, and enzymes.

Neurotransmitters are substances that are needed to transmit mention from one nerve to choice nerve.
Wheat

Wheat products, once oatmeal, is a source of liveliness for the brain. Oatmeal is a amassed grain products that contain fiber, vitamin B obscure and vitamin E are antioxidants that protect nerve membranes.

Once you know what food sources are needed, you are after that required to determine the dosage intake needs in a day. Because the needs of protein and supplementary nutrients is every second in each age. This will be explained progression in the considering table.
