Habitable planet found next to our star system

A habitable planet found near our star system around 4.2 light year apart, a star system called Alpha centauri system. This system has 3 stars namely Alpha centauri-A , Alpha centauri- B and Alpha centauri- C or proxima centauri
Alpha A- B are twin stars and proxima centauri is dwarf star a planet revolves it called proxima centauri- B, this planet lies in habitable zone and yet it has a possibility for life but this planet is 4.2 light years away even it is the closest star to earth but the distance is high 24 trillion miles away

How far it is

For Example If we travel to proxima-B with the help of NASA voyager 1 spacecraft which is moving at a speed of 38,000 miles per hour it will take 70,000 years to reach this planet is close to its star probably it has a chance of tidal locking which means one side of the planet face is always day and another side dark night always there is no day night cycles
the habitable zone in the planet is at the Twilight zone where the day and night meets gravity is about 10% greater than earth

How to calculate age of tree using ring without cutting

How to calculate age of tree using ring without cutting The rings in the trees are used to calculating the age of the trees and tells what the weather was like during each year of the tree’s life. The light-colored rings represent wood that grew in the spring and early summer, while the dark rings represent wood that grew in the late summer and fall. One light ring plus one dark ring equals one year of the tree’s life. The color and width of tree rings can provide snapshots of past climate conditions. For example, tree rings usually grow wider in warm, wet years and they are thinner in years when it is cold and dry. If the tree has experienced stressful conditions, such as a drought, the tree might hardly grow at all in those years Calculating the age of the tree without cutting The age of the tree can be calculated without cutting the tree with the help of an instrument called Increment borer this instrument is bored into the tree up to the centre and collect t

Light speed is possible

Light speed is possible Yeah ,light speed is possible but want for an enormous amount of energy.Okay ,how much energy? It's approximately equal to the Big Bang's energy.You must know about one truth,but this one is scientists theory and no one in this universe is not able to prove practically.Because of our life span is very less compared to universe and suppose you want to proof that you must create very powerful engine.This engine having equal amount of big bang's energy.And start the engine ,You set origin (0,0) from your location and you will set your engine balance your origin point.After starting your engine the earth will move more than 3 lakh kilometers and also whole galaxy in just one second.But you will not submit your results to earth ,it goes continuously more than light speed.Yeah we are travel more than light speed and we are the example of achieve light speed.When Big Bang happens it releases enormous amount of energy ,this energy expands our entire mat

Why computer mouse have red LED light?

Why computer mouse have red LED light? A computer mouse is a optical mouse, which uses a light source, typically a light-emiting-diode, and a light detector, such as an array of photodiodes, to detect movement relative to a surface.Variations of the optiocal mouse have largely replaced the older mechanical mouse design, which uses moving parts to sense motion.But why red is mostly used, simple as red diodes are inexpensive and silicon photodetectors are very sensitive to red light.
