  1I/2017 U1 'Oumuamua' is the scientific name of Omuamua   Omuamua was the most recent interstellar object detected while passing through the solar system. 1I/2017 U1 ‘Oumuamua, was discovered on October 19, 2017, by the University of Hawaii’s Pan-STARRS1 telescope, which is funded by NASA’s Near-Earth Object Observations (NEOO) Program, which finds and tracks asteroids and comets in Earth’s neighborhood. Initially, it was classified as a comet but after some observations like speed and direction of path no signs of cometary activity were revealed as it slingshotted past the Sun on Sept. 9, 2017, at a blistering speed of 196,000 miles per hour (87.3 kilometers per second).   Size, Shape, and specifications Omuamua was The first confirmed object from another star to visit our solar system, It was looking like a rocky body and somewhat cigar-shaped object, very weird straight and slim shape and its color was reddish hue due to effects of irradiation from cosmic rays over ...

  Mars is the 4th planet of our solar system and the nearest planet of Earth. 1610 was the year when Galileo Galilei discovered Mars with telescopic observation, the distance between the sun and mars is 228.19 million km. Behind the mars, there is the belt of so many Asteroids. The orbital period is 687 days which is quite more than the earth’s orbital period. Planet Mars is surrounded by so many artificial ( manmade) satellites. But mars have 2 natural satellites named Phobos and Deimos. Colonization on a different planet is also known as the Space settlement it is the political concept of space law for human habitation and the taking advantage of all-natural resources of that planet where we want to colonize. Yes, we can colonize Mars but it is too difficult to survive due to some issues.  Mars is on the boundary of the Habitable zone. A habitable zone is simply the orbit at a certain distance from the star where a planet or planetary surface can support water with sufficien...

  The pole in the barn paradox is the thought experiment related to the special theory of relativity which is also a famous variation in the twin paradox. We have to imagine references, because everything in the universe is happening concerning others, and if we have to understand the paradoxes then we have to understand the reference for smooth imagination. The paradox is an antinomy, It is a logically self-contradictory statement. If we want to understand with a reference language then the paradox is a statement that runs contrary to one's expectation. To understand the pole in the barn paradox we have to understand length contraction first. Length Contraction:   It is the basic concept of relativity in which a moving object’s length is measured to be shorter than its proper length The proper length is the length measured when an object is at rest in its frame of reference. That’s why I told you that the reference is a must to imagine. Suppose, there is one train A of 4000cm...
