Since light from distant stars have not reach us will the sky get brighter with time?

No. The vast majority of stars are so far away that even though their light is reaching us, they cannot be seen without a telescope. Additionally, the farthest stars from Earth are moving away from us so fast that their light is redshifted beyond the visible spectrum.

When the ultraviolet light from hot stars in very distant galaxies finally reaches us what form does it reach the Earth in?
visible light
Why do the say when you look at the night sky you are looking into the history of the universe?
It takes light from distant stars years, in some cases millions or even billions of years, to reach us. When we see the light of the Andromeda galaxy, M31 (which is visible with the naked eye), we see how it was about 2.5 million years ago, since that is the time it took its light to reach us.
Do you think science can be used to study life in another galaxy?
not right now. we can't even detect many planets outside our solar system since they're so small. Even if we could, light would take maybe millions of years to reach us (off the top of my head, it takes 18 minutes I think for the light from our star to reach us)If anyone has a chance to do it though, it would be science... in the distant distant future.
Why do people say looking at stars is like looking in the past?
Because the speed of light is finite (around 186,000 miles per second) and the stars are so distant, it takes a long time for the light to reach the telescope from the stars - at least 4.2 years. Many objects are millions of light years distant, meaning that what we see in the sky is from the distant past.
How can a coconut reach a distant island?
by water
How can the light from a distant star be old It would imply the star moved away faster than the speed of light?
Since stars are so far away, it takes a very long time for their light to reach us. The closest star to our sun is Proxima Centauri, which is 4.218 light-years away. This means that it would take 4.218 years for light (travelling at a speed of 300,000 km/s) to reach us from this star. As a result of this time delay (4.218 years), we are not seeing this star as it is right now - we are seeing it as it was, 4.218 years ago.The Andromeda Galaxy, for example, is significantly further away: it's approximately 2.5 million light-years from us. Since it has taken about 2.5 million years for the light from this galaxy to reach us, it is 2.5 millions years older than it currently appears to be.Nothing can travel faster than the speed of light. Even if it were possible for a distant star to travel this speed away from us, or even faster than this, it would mean that the light from this star would never be able to reach us.The most distant stars (in other galaxies) may appear to be moving close to - or faster than - the speed of light. This is due to the expansion of the fabric of the universe.
Stars brighter than others?
You bet. Stars are the brightest, except for a supernova explosion they are visible to the naked eye though being millions of light years out of reach.
Will the brightness of a light change with the size ooof the battery?
The brightness of the light will change with the voltage of the battery.That's not always related to its physical size.The higher the voltage is, the brighter the light will be, until you reach oneparticular voltage where the light goes out, because you have burned it outwith overvoltage.
How long does it take stars light to get to us?
In our Solar System, we see light from our sun reflected off the planets. In more distant galaxies, light from many millions of stars takes a long time to reach the Earth. It takes light 4 years to reach the Earth from Sirius, a near neighbouring star. Using the Hubble telescope, we can see the light from the Eagle Nebula, which takes 7,000 years to reach the Earth.
Why astronomers have difficulty looking at distant stars except?
Astronomers have difficulty looking at distant stars because while we have highly specialized telescopes, they are in constant contention with various other celestial bodies. In addition to this, the light of distant stars takes hundreds of thousands of years to reach us, making it impossible to get a current look at a distant star.
What is The amount of time it takes light from the most distant stars to reach earth?
The most distant stars we can see (at least in principle) now are almost as old as the Universe; so, about 13 billion years.
How would you use the adjective distant in a sentence?
To denote distance that an object is - one that is far away. "It takes millions of years for the light from distantstars to reach us here on Earth"
