Will the Big Bang Happen Again?

Big Bang…Again?

According to the astrophysicists, the Big Bang that expanded and stretched the universe can’t happen again because the universe is still expanding. Will the expansion continue forever or will there be a day when everything stops? What would that look like?  Like an airplane that defies gravity with the speed of forward motion, do we need to worry about all things in the universe just dropping out of the sky without forward propulsion?

Even such, the Big Bang keeps us wondering about life itself and how insignificant we may be in the overall scheme of existence. From science, we know that atoms are the smallest particle of an element. Are we or even the world itself just atoms in a system where math doesn’t exist to explain how little we are on the ladder of life? Scientists say that all of the ingredients that were gathered at the time of the Big Bang can be found inside the human body. We are matter and matter is defined by anything that has mass and takes up space. Come to think of it, my mother used to tell me something about “just taking up space.”

The Law of Conservation

Besides trying to figure out the universe and solar system, science can be very confusing. For example, the Law of Conservation of Energy states that energy can neither be created nor destroyed. However, it can change form, as is realized in changing chemical energy to kinetic energy. Ingredients found in dynamite are made up of chemicals, and once the fuse is lit, there is an explosion. The explosion then becomes the kinetic energy and nothing seems to exist afterward, save maybe a few scraps of debris on the ground.

A rule of the above mentioned Law of Conservation of Energy states that perpetual motion cannot exist without an energy source or power to keep it going. This rule seems to support my point at the opening of this post about the expanding universe and going from the Big Bang to continued expansion. At some point, things stop — unless there is another Big Bang to keep things in motion.

Control Static With Our Products

At Static Clean, we manufacture charging power supplies that apply energy to applicators that attack atoms or air molecules to create ions. Of course, that is not the only reason why we build this type of equipment. We are a static control company, which means we also build air ionizers that are used to control static events and prevent explosions on equipment where volatile chemicals vapors are involved in the process.

If static is not kept to low levels explosions can occur. Like the stick of dynamite exploding, companies have to deal with problems associated with converting chemical energy to kinetic energy. For help in controlling static and preventing fires and explosion, contact Static Clean International for expert advice.

Cleanrooms: Controlled Environments

In a manufacturing environment, complete sterilization is more important than you might think.

A cleanroom is a controlled environment where products are manufactured, typically found in electronics, bio-pharmaceutical, medical device and pharmaceutical industries. Clean-rooms are planned and manufactured using strict protocols. Did you know that a particle 200 times smaller than a human hair could cause a major disaster in a cleanroom?

In order to keep that environment sterilized, contaminants that are developed due to people, processes, equipment or facilities need to be controlled to specific limits. Airborne contamination must be continually removed which impacts factors such as air flow rates, pressurization, temperature, humidity and filtration.

There are four principles which apply to the control of airborne contamination in cleanrooms, but we believe there should be a fifth principle added to that list.

The four recognized principles are:

  • Filtration: Cleanrooms need to be designed so that most of the contamination in the air is filtered out.
  • Dilution: Cleanrooms need to be supplied with a sufficient volume of fresh air at regular intervals so that any contamination generated by people working in the room is first diluted and then removed from the room. This is achieved by having a set number of air changes per hour. The minimum requirement is normally twenty air-changes per hour (that is the room air volume is replaced every three minutes).
  • Directional Air Flow: For ultra-clean activities undertaken in unidirectional airflow cabinets operating at EU and WHO Grade A (ISO class 5), the air needs to move in a straight direction so that any contamination generated within the area is removed. This is achieved by having the air enter at a high velocity (normally at 0.45 meters per second ±20%).
  • Air Movement: The air within a cleanroom needs to keep moving so that any contamination remains suspended in the air rather than being allowed to settle onto surfaces. This is achieved by having unidirectional or turbulent airflow.

The fifth principle we would add to this list would be ionization. Adding ionization to the air coming into the rooms or at various workstations where people and plastics are part of the process…and the problem. Ionization will help to dislodge particles, keep particles airborne and reduce static levels on plastics that will prevent the attraction of contaminants.

Preventing any contaminants from entering a clean-room requires a commitment, but the importance should not be underestimated. Follow strict procedures and guidelines for entering and cleaning clean rooms to ensure that your product is not compromised!
