Ok, Amal - I'm tired of seeing this thread exist without some real answers to your obviously well-intended post.
So, one by one, here goes (please note, some humor in here, but I always answer the question to the best of my ability.

We don't know. We have some theories, based upon a lot of observed data, but no definitive proof.

Was the universe created from nothing?

This violates our current understanding of causality, but probably not. However, in the big bang (or brane, rip, tear, etc.) conditions might have been/are different.

Who is older the earth or the universe?

Who on Earth? No one. Who else? I have a theory, but that violates the terms of the forum.

Why is the universe accelerating?
|
Most astronomers believe it's dark energy. I believe Darth Vadar forgot to drop out of warp. No, actually some Jawa tinkered with an R2 unit and SHAZZAM!
Ok, I
really believe it's because c has changed since the universe began which cause an apparent redshift, leading to the illusion that the universe is accelerating when it's actually decelerating. Or it could be that as it expands, less matter fills each point's "observable sphere," as as the stars at the edge travel beyong the Hubble limit, their gravitational attraction is lost to the effect of keeping it together. It could also be that redshift is porportunal to a reduction in gravity, just as it's proportional to a reduction in photonic wavelegth.
Hmmm... I'll have to start another thread on this one...

Is the universe a hologram?
|
No. Holograms reflect light. They do not emit light. And since they were an invention of man, it's unlikely someone else erected one. Furthermore, our original deep space probes are still going, way beyond Pluto. That's a might large hologram. And no, holograms are static. They do not creating changing events like pulsars and supernova. And no, holograms don't emit neutrinos as we observed with at least one supernova event.
So, no. The universe is not a hologram.

What is time and eternity?
|
Time is the distance/velocity it takes me to travel from point A to point B. The upper limit the difference between two points in space is defined by the the velocity of light. Eternity encompasses the beginning and end of time.

What is our purpose on earth?

Same thing as every other living organizing on the planet: survive and procreate.

Why are death and life created?

Life is created. Death just sort of happens when the life-time entropy arrow hits bottom.
We do.
We do. Possibly others, but we don't know that yet.
