lovetruth said:The universe must end somewhere; there cannot be infinite matter extending the infinities of the space. I kno its not proven the universe is finite but, don't u think intuitively that universe must end somewhere although we are not capable of seeing its boundary.
Nice reply thou.
ZapperZ said:What is this, and how do you know this?
Zz.
This is some really speculative nonsense. None of the available evidence supports it.lovetruth said:We kno that most of the electromagnetic radiation escapes the boundary of the "physical(corporeal) Universe".
LostConjugate said:All matter is expected to be radiated away, even black holes, far into the future. However it my not be the end of the Universe, it could lead to another big bang event.

There is not an absence of evidence regarding cosmology. Maybe you should actually learn some of it first.lovetruth said:. In the absence of any evidence
lovetruth said:Pure Intuition. In the absence of any evidence, we are always forced to speculate on basis of our previous experience. This is how science works, using the pattern to predict things. An infinite universe will mean infinite matter which is unconceivable by our current understanding. Our solar system has boundaries, so does the galaxies. By same analogy, universe must be finite however vast it is.
An electromagnetic wave is a type of wave that is created by the oscillation of electric and magnetic fields. It consists of both an electric and magnetic component, which oscillate perpendicular to each other and to the direction of the wave's propagation. Examples of electromagnetic waves include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
Energy and electromagnetic waves are closely related because electromagnetic waves carry energy as they travel through space. The amount of energy carried by an electromagnetic wave is determined by its frequency. Higher frequency waves, such as X-rays and gamma rays, carry more energy than lower frequency waves, such as radio waves. This energy can be harnessed and utilized in various ways, such as in the form of electricity or heat.
Yes, electromagnetic waves can travel through a vacuum because they do not require a medium to propagate. This means that they can travel through empty space, unlike mechanical waves which require a medium, such as air or water, to travel through. This property of electromagnetic waves is what allows them to travel through the vastness of space and reach us from distant stars and galaxies.
Electromagnetic waves play a crucial role in the universe as they are responsible for transmitting energy and information across vast distances. They are also the primary means by which we gather information about the universe, through telescopes and other instruments that detect and analyze different parts of the electromagnetic spectrum. Electromagnetic waves also play a role in various natural phenomena, such as the interaction between the Earth's magnetic field and the solar wind.
Electromagnetic waves can interact with matter in various ways, depending on the frequency and properties of the wave. Some waves, such as radio waves, can pass through most materials with little to no interaction. Others, such as visible light, can be reflected, refracted, or absorbed by different materials, giving rise to the colors we see. High-frequency waves, such as X-rays and gamma rays, can interact with matter more strongly, causing ionization and damage to living cells. Understanding these interactions is crucial in fields such as medicine and telecommunications.
