For an impact, 2 things is needed. Each of these 2 things have a speed. None of them exceeding c. In a collision between 2 things holding c, the energy freed due to the collision is that of 2cc times involved mass. (?) So no speeds larger than c. Impact has no speed 🙂

Time, Dimension, Space are similar.

Traveling trough space is bigger than heaven and hell. Because heaven,hell will be somewhere in this universe or other dimensions.

Blackhole is the thing that interest me the most. They say Black hole get to another dimension with incredible force.

I don't think the black hole is the problem,
Or even other dimensions, because they must all have a fundamental reason for existence. The truth is a question of reality.

The problem is what is reality and why is it the way it is..QED

It would seem nothing is the question..

Well said, Philosophil. I would only add that theories and models usually have limits. Even when discussing big things -- like the universe -- our models of cosmology are generally limited to the universe itself, data beyond which is (currently) unavailable. Thus, "What does the model tell us about conditions outside the known universe?" yields the sensible answer, "Nothing. It's a model of the known universe. It has little to say about the unknown context of the known universe."
As far as I understand it, all ideas regarding mulitverse, conditions prior to Big Bang, etc, are strictly speculative. They cannot (currently) be observed or tested, so the questions lie beyond the realm of empirical science. They are just as well addressed by a meta-physicist or a theologian.

Then finally the big bang..

Just my opinion,

Perhaps there is the nothing and if one bang took place there has to be many. So perhaps a multiverse within the nothing?
(but not absolute nothing)

So either energy has always existed or there is more to this and the dreaded infinity..then there is the strange strong nuclear force.

And the bit that intrigues me the simple pollen in water..😀 (we are nuclear waste)

Thanks for the links! OK so the expansion is accelerating. What physical process accelerates before it retardates? An explosion must have positive acceleration in the beginning as the involved matter can not obtain its highest speed instantly. So matter in an explosion accelerates in the beginning of the explosion process.

But maybe it is not dark matter/energy that drive the expansion but rather the bang itself. This would mean that we are just in the beginning of the explosion and we are still waiting for the de-accelleration. Dark energy could rather be the contra force to the explosion but it has not yet the power to de-accelerate matter dispersion. But eventually it will make the acceleration and speed of matter = 0 ("everything becomes dark") and the implosion begins, driven by dark energy, ending with next big bang.

Antigravity

There's a theory in which the universe's antimatter didn't annihilate , leaving a preponderance of matter behind.
The majority of this antimatter is clumped in the great "voids" lying between the galactic groups.
Attractive to itself, but gravitically repulsive to positive matter, this antigravity pushing against positive matter fuels the great expansion's acceleration.

I had a strange thought last night,

I thought about this picture and the .03% which is us..

I was lying in the dark and the thought of the 73% this darkness?
Then the realization this is real its out there..
I'm in the unusual bit not the normal/majority part of the universe..

Then what's out there? crossed my mind..a bit spooky I guess. (that's a big 73%)

Then the thought..how can you have 73% of infinity?
There has to be some strange twist to this plot!
The thought of drifting through this blackness and reaching a black mirrored surface (the edge of infinity)
Then the thought of the four dimensions within infinity..
Infinity<<what exists and what doesn't.

Did it really take all the other stuff (73% etc) to create the .03%.

Just a fun thought..ie you need a universe to create life.

Perhaps life is a form of collateral-damage of this universe...

Anyway, what we have now ought to equal what existed before the big-bang in some way... and size does not matter (ahum 😀). perhaps the "expansion of the universe" is a spin-off of lightspeed and mass of the universe...

Peridot Gemstone found on mars,

I thought this was interesting I hadn't seen it.
BBC NEWS | Science/Nature | Gemstones found on Mars

Perhaps gems may fuel more exploration..a peridot ring from mars might be nice to have..

With the Martian bacteria encapsulated inside that nobody knows about...😀...😕..😱

Martians and Gemstones from mars are green in colour..LOL

Maybe size is meaningless, as the universe is always the same size relative to itself.
Maybe this is how entanglement works...

That's an interesting thought,

Reflection..

Could infinity always be the same size?
What would that mean related to mass?
Could infinity be different sizes?

Surly if the size remained the same and mass increased the universe would get closer together? (more compact)
Unless its losing mass. (energy leaking away into something else...)

A thought of a blob of the universe with energy boiling off like steam from a boiling pan of water.

Could infinity have infinite mass?😕
That would be nuts<<infinite mass = infinite energy

If infinity had infinite mass would it be static? Or would there be a continuous matter energy conversion? (like we see in the universe)
Critical mass = Big bang?

The problem with all the ideas is they assume something is going somewhere..or there is a meaning i.e. the end justifies the means.
Or that there has to be some meaning in everything..

The problem for this is that the universe seems to obey laws of physics..ie we have written the laws to explain what the universe complies with. Why should the universe have laws at all...or even why does it have laws.

Are the forces we know about all there is? If the universe is going to end then the laws are not permanent..ie we are trying to explain the reality of the universe with a book we have written. (the universe according to mankind) This would reflect into the case that every idea we have is probably wrong and only of any relevance to us. This could be true in all aspects of life the universe and everything.

Before the universe if there was a before, then would the laws of physics apply?

Ie when I die will the laws of physics apply to me? (If I exist or not)
Scenario, I die I cease to exist..I die I still exist<<even if I don't want to.

The universe dies, it ceases to exist or the universe dies and still exists?

Or the ridiculous possibility that,

Both I and the universe don't exist and therefore cannot die?

What is relevant:

The universe exists to me (when alive) and when I die it is gone.
Or
The universe exists but I am dead.

Take it one step further the universe is self aware and when it dies? (reality ends)
What is reality?(a moment in time)

Reminds me of the mind robber in Dr Who..what is reality? Is it the permanent everything? Or a state of mind?
