What if the "Big Bang" was not the Beginning Point of our Observable Universe?
Abstract: The Big Bounce theory envisions the Big Bang as the start of a period of expansion followed by a period of contraction. According to this viewpoint, there was a Big Crunch (another singularity) followed by a Big Bang, or, more simply, a Big Bounce. This implies that we could be at any point in an infinite series of universes, or that the current universe is the very first interaction. But …

Electrical Discharge Machining (EDM) ON Titanium alloy workpiece using graphite
Abstract: In modern industry demands of titanium alloy is increasing day by day. Because it has many several characteristics such as low thermal conductivity, low elastic modulus. Application of Titanium and its alloys now a day in different field such as aerospace industry sports car etc. Therefore it is replacing different metal such as aluminium in many applications .It has high corrosion resistance and high strength – to – weight ratio …

New Advanced Life Support System (LSS) for long-duration missions on the International Space Station (ISS) and Interplanetary Spacecraft
Abstract: Oxygen in the air and the water are vital for the smooth operation of the crews of the International Space Station and interplanetary spacecraft during long-term flights. Replenishing by the water, oxygen and micro algae biomass by delivering them to the International Space Station or to the interplanetary spacecraft is not economically viable. Therefore, the task arises of using and developing new systems that use the regeneration of oxygen, hydrogen, …

Relativity of Wavelength According to the Relative Velocity between the Observer and the Wave Source
Abstract: An observer on Earth can observe the path of the Moon and Earth around the Earth and the Sun, respectively. Both are elliptical orbits in which the Earth and the Sun are concentrated, respectively. But how do we accept both paths together, where one cannot imagine the Earth as stationary while the Moon revolves around it in one of them and at the same time the Earth itself is the …
