how can energy be converted into mass?

Question

I am talking about Einstein's theory. Can it be practically possible(leaving the plants out)?

Answer 1

It happens all the time in paricle accelerators. (When two particles smash into each other at almost the speed of light.) The total mass of all the peices is more than the mass before but the energy is less...

Answer 2

Converting mass into energy is much easier than the opposite. To convert energy into mass HUGE temperatures and energies concentrated on one spot are needed. Most of the mass in the universe was created a short time after the big bang when the temperatures were immense. Particles with mass are also created out of pure energy in particle colliders, because only there people can recreate the conditions that were just after the big bang. Edit : The mechanism is called the Higgs mechanism from which all the fundamental particles acquired their mass but it's very complicated.

Answer 3

No it is not possible on a large scale. In particle accelerators, atoms are run at high speed and then smashed to convert energy, resulting is entirely new elements (masons, positrons, etc.) with a very short life span. Here, the new mass is not produced from the energy but atomic structure is rearranged to produce new elements.

A mass can be converted into an energy, but reverse can not be done easily. Theoretical physics states that if we increase the temp. of a object by pumping energy, then above 10^14 K (100 billion degrees kelvin) the additional energy is converted into mass. This was how the universe formed and stars produced. This high temp. was achieved by tremendous pressure due to collapse of universe dust about 4 billion years ago.

Answer 4

If a mass would be given power to move at the speed of light ,its atomic structure would break up into pieces and the pieces would fly out at the speed of light, and each piece would have an energy equal to the mass per piece times the velocity of light squared.
If a mass is moving the mass is said to have energy. Inside the atom of a mass structure all the micromasses are moving inside ,therefore the mass is said to have energy structure.
As you can deduct from the above Energy does not convert into mass. Without motion no mass can be structured.
Therefore Energy is a phenomenon(a process=not a quantity).Mass does not convert nor does energy.
Mass remains mass and energy remains energy=two different concept in physics.
In the Universe mass is always conserved and so is energy.
Based on this postulate the Universes is a conservative system=From this stems the "Law of Conservation of Energy "and another law called ,the" Law of Conservation of Mass."
Einstein relativity theory never stated that mass gets converted.
All it says is that the maxmimun that a mass can be accelerated to is the speed of light.
The formula for the description of a mass stuctural energy is as follows;
E= M xC^2
E= energy ,C= speed of light, M is the mass structure.
This equation was formulated by Henri Poincare in 1900. This energy formula was later used by Eintein in his Theory of Relativity.
Ps ; when a Plant absorbs radiation from the Sun ,it is really absorbing mass at a certain frequency.

Answer 5

Mass can be created from energy in the labs. When they do it, using some sort of accelerator like a collider, they create both matter and anti-matter. In fact, both must be created as pairs when mass is created. The anti-matter has an extremely short life; so it does not persist. It usually forms energy particles, like photons, upon colliding with matter. In other words the anti-matter reverts to energy. [See source.]

During the first few seconds after the big bang, our known universe was filled 100% with energy. No matter...no quarks, no electrons, ... nothing...just energy. But, as the universe cooled, some of that energy sort of congealed to form the first matter...the quarks.

The bottom line, energy has converted naturally to matter and energy has been converted to matter and antimatter in the lab.

Answer 6

I'm just going to throw out there that photosynthesis is absolutely not the conversion of energy into mass. It's using energy to manipulate matter or mass. Two completely different things.

Answer 7

yes i think it is possible
E=MC2
structor of a atom is made from nutrons, protons, and electrons.
when a atom with a no of proton and nutrons in its nucleous is strick with a positive charge it splits and a new compound is formed but with it a lot of radition is also emeted in form of alpha, beta, gama ect rays. and a lot of heat energy is also released and the mass of the new formed element is less than the first one.
all the protons are positive charges which is heavy in mass.
and electrons are negtive charges which are lighter inmass
and neutrons have mass only
if we are able supply :- 1 into speed of light energy than we can produse one gram of mass
we only have to make structure of a atom but a lot of energy is required
in the universe the total mass and the total amount of energy remains the same only the mass can be converted to energy and energy to mass by some or the other process.
if we will strick a lot of energy in a vacume to each other in form of electricity, sone rays, like uv rays, and a lot of heat is supplied the i think it is possible.

Answer 8

From what I understand, when a particle called an electron meets a particle called a positron they destroy each other and create gamma rays, these gamma rays are energy and the have been observed in labs to convert back to particles which is matter.

Answer 9

The answer you're looking for is pair production. This occurs when a high energy photon becomes two particles (well particle and antiparticle) the type of particles created depend upon the mass of the incident photon. This happens in particle accelerators and in the atmosphere when cosmic rays hit.

Answer 10

Theoretically it's possible, because Einstein's equation states that mass and energy are essentially the same thing. However, the reactions that we are familiar with (fission and fusion) convert mass to energy somewhat irreversibly. I am not aware of any reaction that will allow us to add energy to a system thus creating more mass than originally contained.

To respond to one of the previous answers: photosynthesis does not represent a conversion of mass to energy, it represents a USE of energy to assist in the synthesis of mass at hand into new forms of mass.
