What else can I help you with?
How fast does light from stars travel?
At the speed of light, which is 299,792,458 metres per second.
Can a light travel through a vacuum?
Yes. Refer to stars - space is a vaccuum (though not a perfect vaccuum) and because light can travel through a vaccuum, we have day and night here on Earth. We can even see light from other stars light years away.
How do we know light can travel through outer space?
We can see stars.
How do you know light can travel through outer space?
Light can travel through outer space because it propagates as electromagnetic waves, which do not require a medium to travel through. This means that light can move through the vacuum of space without any obstacles. This property of light allows it to travel vast distances from its source, such as from stars to telescopes on Earth.
How far does the light from the stars travel to earth?
This varies widely, between about four light-years for the nearest star (after the Sun, that is), to billions of light-years for stars in the farthest observable galaxies.
Why is light you see from stars several years old?
it takes light long to travel so you see it late
Can light waves travel on a vacuum?
I think they can, since that's how you see the sun and the stars.
What units are for distance between stars?
The correct unit to describe the distance between stars is the "light year", the distance a photon of light would travel (through a vacuum) in a year.
Is there light in outerspace?
You mean, light such as comes from stars like the Sun? That kind of light? In outer space, where the stars are? In that big vast open place that the light has to travel across before we see it ? Gee, that's a tough one.
Are we looking at the past when we observe stars?
Yes, when we observe stars, we are looking at the past because the light from stars takes time to travel to Earth, so we see them as they were in the past.
Can you travel slower or faster than the speed of light since supermassive blackholes launch stars out at 99.8 percent or something the speed of light by using regular space travel to go over 100?
Can you travel slower than the speed of light? Yes.Can you travel faster than the speed of light? No.Supermassive black holes launching out stars... No, they launch out jets of matter, not entire stars.... at 99.8 percent or so... Yes, those streams of matter reach very high speeds. But those speeds are always lower than the speed of light.Space travel to go over 100... There is probably no way to travel faster than the speed of light.Can you travel slower than the speed of light? Yes.Can you travel faster than the speed of light?

Why do stars take so long to change?
The stars are light years away which is the distance light travels in a year. A light year is about 3x108km. The farther something is from you the slower they seem to travel so the stars don't look like the are moving. In reality, they are moving very fast.
