How Do Telescopes See The Universe?

The universe consists of space, time and the vacuum of the universe and their contents including stars, planets, galaxies, and everything else that makes up the universe. The Big Bang Theory is the most dominant cosmological model of the early evolution of the universe. This theory explains the composition of the universe as it was when the universe was at its very first formation. It also predicts the development of the first stars and the birth of planets.

The theories of Relativity suggest that the universe contains unperceivable matter that has no external gravitational pull. 

The speed of light is independent of any reference system, including that of the speed of the Planets. The speed of light can go faster than the speed of the universe, if you were to travel faster than the speed of the universe, or vice-versa. In Relativity, it is said that a moving source of mass will always have an effect on another source, even if they are in separate universes. Inflation, theory of gravity and the big bang theory all predict the creation of a large number of dwarf galaxies, as seen in spiral clusters, which are very common in the present-day universe.

Inflation predicts the existence of very heavy deformed planets in the early universe, which are much less dense than the neutral gas planets found around normal stars. 

It is thought that such heavy planets formed from the collisions and other gravitational perturbations that took place at the beginning of the universe and that they constitute the seed material that makes up the solar system and the atomic clouds. The universe contains many dark matter grains in the form of colliding atoms and it is suggested that these dark matter grains affect the movement and rate of the electrons in our galaxy. The speed of light in the universe is thus very dependent on the distribution of dark matter. Astronomy has revealed that almost all the visible matter in the sky is made up of dark matter. The present-day theories suggest that almost all stars have planets in their own systems.

Astronomy indicates that nearly half of the known planets in the solar system are not only inhabited by human beings, but also by microbial life.

Some of these exo-planets circle around other bigger planets in the solar system or some of them are extremely hot and dense and have large amounts of water oceans. The present-day theories suggest that all the gas in the universe consists of dark matter that is invisible to us but is in constant movement with the dark energy that accounts for the accelerating expansion of the universe, according to the Big Bang Theory. The present-day telescope like the Planck telescope at Institute for Radio Astronomy in Germany can detect these tiny Dark Matter particles, which are produced in the high energy physics region.

The present-day cosmology suggests that the earth is round and that it is not the center of the universe, as some scientists have argued. 

The diameter of the earth and its orbit period around the sun as determined by radial velocities of satellites, proves that the earth is not round, according to most scientists. They believe that it is a satellite or a dwarf planet. The satellite phase can be explained if you consider that the moon is a satellite too, which goes round the earth on a yearly basis.

There are some scientists who believe that the universe could possibly be infinitely big, according to some recent research.

In this scenario, there could be as much as 100 billion visible grains of sand on the moon. This could potentially be true, as some recent research has revealed that grain sizes are consistent with the models of recurrence theory. According to this concept, the law of biogenesis in nature is supposed to be the key to explain the observed grain size and its relation to the other models of natural cycles. The existence of a galaxy or a cluster of galaxies could also be an indication that the universe is very big and contains an infinite number of stars.

If we try to travel faster than the speed of light, we will encounter various problems. For example, if the speed of light is going to be faster than the speed of the universe, what will happen? The vacuum will be left behind, and in case of traveling faster than the speed of the void, it will swallow the molecules of our body, leading to death. Therefore, traveling faster than the speed of the universe will lead to problems for our body, and that is why scientists are trying to discover ways to go beyond space and reach the stars.

Although it was not possible for ancient astronomers to see around us, with the help of modern technology we can use satellites to view the universe.

Most amateur astronomers use a spectroscopic device to study celestial bodies through obtaining data in the form of infrared or ultraviolet radiation. This method is able to measure the temperature and composition of celestial bodies. We have now come through almost 70% of the total energy emitted by the cosmos, which can be seen with the unaided human eye. Hence, we can conclude that the observable universe must be extremely large, but we cannot see its minutest details.
