How fast would antimatter make the shuttle goe in space?

An antimatter-propelled shuttle would go as fast as a normal shuttle. What defines the necessary speed for a shuttle is a combination of two factors: a) The escape velocity of Earth's gravity field (the speed at which a body needs to be launched in ballistic flight in order to exit from the gravitational pull of Earth). b) The amount of acceleration the cargo (or crew) can stand. Antimatter engines are actually designed to be fired in space, since matter-antimatter reactions produce gamma rays, which would leave a trail of radioactive air in their wake, if fired in atmosphere. The true power of antimatter propulsion is the capacity to use a very small volume of fuel to accelerate a ship in space for a very long journey. They are not cheap, they are not easy to build and they are not yet feasible (because we cannot, as yes, contain antimatter for long), but, in thesis, they can take people far far away from home. ;)


Why do antimatter and matter react when they touch what's the chemistry of it?

Matter-Antimatter reactions are not chemical reactions. They are very complex sub-atomic reactions, and the nature of the annihilation depends on the matter and anti-matter in the reaction.One of the simplest matter-antimatter annihilations is between an electron and a positron (an anti-electron). The electron has a negative charge and the positron has a positivecharge. When they come in to contact (under the right conditions) they must annihilate, since one cancels out the other.However matter cannot simply dissappear, so it must be converted to energy via E = mc^2 where E is the energy released, m is the combined mass of the electron and positron, and c is the speed of light.In the case of the electron-positron annihilation this results in two gamma rays of a certain energy.As the size and complexity of the matter-antimatter reactions increases so does the complexity of the reactions.

Where can you find antimatter?

Its is formed when two atoms bang into eachother. Scientists are trying to trap antimatter to study it and learn more about it.


How strong are the nuclear bombs made today compared with the atomic bombs you dropped on japan?

In very round figures modern fusion bombs have yields in the range from 200 kilotons to 400 kilotons with a small number over 1 megaton. The two fission bombs dropped on Japan were 15 kilotons & 22 kilotons respectively.


What are two questions physicists have regarding antimatter?

1. Why is there more matter than antimatter in the Universe? Or: Why is there matter at all? (If there were the same amount of matter and antimatter, and it came into contact, it would quickly get destroyed. 2. If antimatter is so abundant, how come we've never come in contact with it or have been able to observe it?


What is the role of gravitational force between matter and antimatter?

Sir Issac Newton proposed theory of gravity. He formulated the relation between the force of gravity and the mass and the distance between the masses. This theory failed to explain as to why there is attraction between the masses and not repulsion. With every attraction you have to have corresponding repulsion. That problem is resolved with the discovery of antimatter. So like attracts like. So matter attracts matter and antimatter attracts antimatter. This fallows that matter repel antimatter. So force of gravity between the two masses of matter or two masses of antimatter is directly proportional to the product of masses or anti-masses (Antimatter). The force of repulsion will be directly proportional to the product of mass and anti-mass (Antimatter). It fallows that the force of repulsion is inversely proportional to square of distance between the two.


Is antimatter greater than infinity?

Antimatter is a substance, while infinity is a representation of a never ending number. They are two separate things, and thus they cannot be compared.


What is a positrin?

A positron is the antimatter counterpart of an electron, with a charge exactly opposite to the electron. Like other antimatter particles if it comes into contact with its matter counterpart the two will mutually annihilate.


What is the mathematical proof of gravitation force between antimatter to antimatter and matter to antimatter?

Sir Issac Newton proposed the law of gravitational force between mass to mass of matter. That is the gravitational force between to masses is directly proportional to the product of masses and inversely proportional to the square of distance between the two. F=G* m1*m2/r2. Here the F is the force of gravity. G is gravitational constant. m1 is mass one. m2 is mass 2. r is the distance between the masses. Now for the two masses of antimatter you have to denote the negative sign to the mass. So the formula is F = G* minus m1 * minus m2 / r2. So here the F is positive number. So there will be force of attraction between the two masses of antimatter. Hence proved.Now you take one mass of matter and another mass of antimatter. The formula is F = G * m1* minus m2 / r2. Here the F is negative number. So there is no force of attraction between the two. Instead there is force of repulsion. So the force of repulsion between the mass of matter and mass of antimatter is directly proportional to the product of masses of matter and antimatter and inversely proportional to the square of distance between the two. Hence proved.So above is the mathematical proof of the gravitational force between the masses of antimatter and antimatter and gravitational force between the masses of antimatter and matter.


What is Pulp yield?

There are two type of pulp yield . Cooking Yield and Bleached Yield. Cooking yield = Bleached Yield/Total loss ( Blow tank to Final stage) Bleached Yield = Pulp produced in ADT X 0.9/Chip consumed (ODT)

Why the mild steel have two yield points?

Low carbon steels suffer from yield-point runout where the material has two yield points. The first yield point (or upper yield point) is higher than the second and the yield drops dramatically after the upper yield point. If a low carbon steel is only stressed to some point between the upper and lower yield point then the surface may develop Lüder bands.
