What is the name of the Appredite homeworld?
Appred (located in the Outer Rim).
How old is light energy?
The light that is now coming to us in the cosmic microwave background radiation was released in an event called "Recombination," which occurred about 377,000 years after The Big Bang, which occurred about 13.7 billion years ago. Thus, for SOME light beams we detect today, our Universe is about 13.7 billion years old.
When was Light the Universe created?
When the big bang theory started the universe, light was created.
How old is the origin of Universe?
13.7 billion years or 13,700,000,000 years. Answer2: The Universe may be immortal and have no "age". The size of the universe is such that it would take 16.7 billion years for light to traverse its radius.
Approximatley how old is your universe?
My universe is approximately 13-15 billion years old. How old is your universe?
What is the longest known distance in light years?
That would be the distance from one edge of the Known Universe to the other. As the Known Universe is believed to be approximately 15 billion years old, that would be 30 billion light years in diameter.
How do astronomers locate other stars trillion light years away?
They can't. The universe is only about 13 billion years old. If there are galaxies a trillion light years away their light has not reached us yet and due to the expansion of the universe, never will. At the edge of what we call the observable universe we cannot make out individual stars, but we can detect galaxies using infrared telescopes.
What is the universe's primary source of light?
Most of the light in the universe comes from the stars. Stars create their own light using nuclear fusion.
Why light has dual character?
WHY does light have a dual character? As far as we can tell, in our Universe, it just DOES. There's nothing about our Universe that would require that light sometimes behaves like a particle, but, whether we like it or not, in our Universe it does.
How can you be sure that the universe is expanding still if the light you are measuring to conclude this is many billions of light years old?
An important reason for believing that the Universe is expanding is the redshift of light from distant galaxies. This is usually attributed to the Doppler effect - the frequencey of a wave changes if the object emitting the waves moves towards you, or away from you.
Which is the fastest thing in Universe?
Tachyons are theorised to be the fastest particle in the universe their slowest speed being the speed of light. But until they are proven to exist, light is the fastest thing in the universe.
How many milky way galaxies end on end to the edge of the universe?
If the milky way galaxy is 100,000 light years across and if the universe is 13 billion years old, you would have 130,000 milky way galaxies, end on end to the edge of the universe.
