What is the largest structure in the universe??
✨The largest known structure in the Universe is called the 'Hercules-Corona Borealis Great Wall', discovered in November 2013 by Istvan hortvan
💥This object is a galactic filament, a vast group of galaxies bound together by gravity, Measuring approximately 10 billion light years in length✨

✨Famous globular cluster M13 has 100,000 stars packed into a space 150 light years across. The centre of this cluster is so crowded that it’s thought that stars crash into each other forming new suns called “blue stragglers”✨

Does sound travel in space?
✨No, we cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel✨

What's inside a blackhole?
✨While they may seem like a hole in the sky because they don't produce light, a black hole is not empty, It's actually a lot of matter condensed into a single point. This point is known as a singularity✨

Will the Universe Ever End?
✨The universe had a definite beginning, called the Big Bang. It's ending is more like the "long, slow expansion". The truth is, the universe is slowly dying as it expands and grows and gradually cools. It will take billions and billions of years to cool completely and stop its expansion✨

How Many Stars Can We See at Night?
✨That depends on many factors, including how dark the skies are where. In light-polluted areas, people see only the brightest stars and not the dimmer ones. Out in the countryside, the view is better. Theoretically, with the naked eye and good seeing conditions, an observer can see around 3,000 stars without using a telescope or binocular✨
