4 times as bright.
"inverse square" = 4 times as bright (1.86 magnitudes)
The farthest known star in the universe is probably in the distance galaxy Abell 1835 IR1916 , which lies some 13.2 billion light years from earth. This galaxy is believed to… be the most distant galaxy in the universe. A link is provided.
Light intensity is one of those things ... along with gravitational force, electrostatic force, and radio-station strength ... that follows the "inverse square" law, meaning t…hat it decreases in proportion to the square of the distance. So if the distance is doubled, then the light intensity is 1 / (2) 2 = 1 / 4 its original value.
At this point there is no edge of the universe, mostly due to thefact that the universe is expanding rapidly (moving outward). (Answer By William Hackman) I believe there is a… edge in this universe, but there is no proofon how far it is right now. Our universe has been expanding for along time, but later on it will start contracting (moving inward)maybe faster than light. And then we'll have a new Earth and a newuniverse and have only good and living, not bad or death.
\nthere is only 1 universe...although there is many galaxies contained in this universe.
There is no end of the universe. The universe goes on for ever and ever.
Who wants to be a millionaire with Eddie Macguire says that it is 4 times as bright but i can not give a scientific reason for this answer
There is no firm evidence of there being another universe. There is conjecture that there may be parallel universes occupying the same space as ours, with the same objects as …ours, but performing somewhat differently from ours. For now, you may want to simply think of our universe extending forever for an unlimited distance.
Please specify the star you're asking about.
Bellatrix , is the third brightest star in the constellation Orion. It is a blue giant and is around 240 light years from us.
The closest (DX Cnc) is 11.8 lightyears away. The farthest is nearly 4000 lightyears away.
In fact, what we call "sky" is our atmosphere whose blue colour is due to the concentration of gases, mainly oxygen of course, and the blue colour is due to the wavelenght tha…t oxygen lets the sunlight to cross. Suppose that the atmosphere was invisible, clear, not blue. Stars and planets would have the same distance. Some are very near to us, relatively to our galaxy, the Milky Way. But other stars and planets in our galaxy or even more distant ones are very far away from our planet. Some stars that you are watching at night may not exist anymore, and what you see is only its light still travelling onto space due to the huge distance they were before they turned into a dwarf star and ceased to glow.
Most stars are in other galaxies than ours (the Milky Way) and are billions of light-years away. The sun is the closest star, 93 million miles from Earth, and the next closest… is Proxima Centauri which is four and a half light-years away. A light year is about seven trillion miles. Stars are extremely far away.
