Just a question.

IS there any proof that dark matter or dark energy exists?

because I don't think there is, but maybe I'm outdated.

Also something that confuse me with the expansion of the universe. If the universe is infinite, and if we are going to end in a big rip, how can the universe be curve and not flat?

Can someone please clarify me? I'm just a simple human in a small planet called earth.

My lifespan is a glimpse in the universe.

No one has a cup of it in their lab yet. It is a name for stuff that must exist because the effect of its existence is seen.

There is the universe and there is the observable universe. The observable universe fits inside the universe. We can only know about the observable universe. Think of the observable universe being an opaque balloon floating in a never ending thing. The balloon can get bigger or smaller. Nothing inside it can see anything outside it as it is opaque. Now if your world is a balloon is it curved?

I reckon it's something the scientists have invented to explain duff experiment results!

Until anyone finds any dark stuff, my theory is as good as anything else :-)

What we as humans cannot comprehend, is that the universe and space is IN-FINITE, i.e. it goes on forever without any end. We have absolutely no comprehension of that concept, and many who have tried have gone mad.


I've tried and look what it did to me !!

All buried inside them extra dimensions, god knows what's lurking inside there.
I have read something just recently about this dark matter, just can't lay my hands on it at the moment but I think it was linking dark matter to the neutrino again.

Michael, or should i call you Mr Marmite :D ?

The universe can be infinite, and maybe this size is beyond our brain cell compreension for now, but are you also making the statment that can exist a multiverse?

500 years ago everyone belived that the earth where the centre of the universe and that the earth was flat.

Now we know that there are planets outside the solar system that maybe have the conditions to sustain life different from the one we have on earth. (by the way not all life needs to be carbon based)

what will we found out next? that there are several universes? that we can travel between them? imagination is the limit and knowledge is always a room that is infinite.

Yup, I agree on that Doc, multi-universes the question is, "What particle if in existence can transgress between universes"? Could it be the mysterious graviton for we know it's a wave but can it also behave like a particle too just like the photon. As you know, particles such as the photon posses duality, i.e. can behave as a wave and as a particle too so is the graviton the same. It's only a hypothetical particle at the moment for no one has yet discovered it but as a wave it does travel at the same speed as light. If scientist can just pin-down the multi-dimensional structure of our universe many unsolved mysteries of science will become understood. Is our universe finite? Well I assume it must have a boundary i.e. that edge of it that is still currently expanding into new space. But is this new space that it is expanding into already occupied by our multi-dimensional structure beforehand. Meaning, are the dimensions of our universe constructed first then the contents of the universe get constructed afterwards inside it but ever so slightly afterwards in time. The question then is, "How far can you stretch a dimension"? If dimensions in a universe once constructed can expand onwards to infinity then the universe too can most probably expand for ever. If dimensions do have a limitation to their effective length then perhaps the universe can not expand for ever giving the hypothesis that it could in the end start to contract. I favour contraction for I believe that universes constantly get born then die with this event happening throughout the infinite space.

Neutirnos can traveltrough multi verses, also Tachyons.

There still existsa relation between speed and how time elaples.

There are several theories that c is a constant,but according tomdern cosmology, is possible to travel faster than lihght.

the problem is if prooven modern physcis has to ber rewritten

better this than yolive in the time of Aristoteles

According to the Big Bang theory the current universe was created from a singularity, and since then it is expanding and moving.

Will it come a time when the universe will have no more mass to expand and will stop? Or will it rip?


It's likely that it will rip apart since recent scientific observations of the universe reveals that the current rate of expansion of the universe is increasing.
