Does the color of light affect the brightness of light?
The simplest answer to the question is to refer to the propagation conditions in a vacuum, where the direction in which the light is traveling doesn't matter and there are are no other effects to confuse the picture ... just the light and the empty space with its intrinsic electrical properties. There, neither the color of the light, nor its wavelength, frequency, or intensity, makes any difference in its speed. A flash of red, a flash of violet, a pulse of radio waves, and a zap of X-rays -- all emitted at the same time from the same star a million billion miles away from us -- will all arrive on Earth together 170 years later, having traveled together all at the same speed.
How many times is a gigasecond?
A gigasecond is equivalent to 1,000,000,000 (one billion) seconds, which is about 31.7 years.
What is the half-life of potassium-40 if a potassium-40 sample starts with 50 atoms and 1.25 billion years later there are 25 atoms?
The half-life of potassium-40 is 1.25 billion years since half of the original sample decays in that time. With 50 atoms initially, having 25 atoms remaining after 1.25 billion years aligns with the expected decay pattern for a half-life.
How old is the universe in 2023?
The universe is estimated to be around 13.8 billion years old in 2023.
How long has the nuclear fuel of the sun been burning?

Is it true the year 12 billion is the end of the world?

How long is the sun likely to live?
our sun will live for another 4.5 billion years
What will be the reason to the end of the sun?
most likely, the end of the sun would be because of its age. it only has about 4 billion years left. A star's lifetime is about 15-20 billion years.

What will humans look like in billion years?
It is impossible to tell what humans will look like in a billion years, if any humans are even alive then. We could change drastically, or not at all.

How big is the univearse?
The observable Universe has a radius of about 46 billion light-years; that would be a diameter of 92 billion light-years. The entire Universe is likely much bigger, but it isn't know how much bigger.
When will it become a billion years?
A billion years from now
