Can something that's made of antimatter be alive and intelligent?

In principle perhaps, but in actuality the answer is almost assuredly going to be no. This is because as far as we are aware very nearly all of the matter in the universe is regular matter. When anti-matter occurs it is only briefly because an anti-matter particle cannot exist for long before meeting a corresponding matter particle and annhilating and releasing very large amounts of energy. Thus, complex structures made of anti-matter, such as are necessary for biological evolution, cannot stably exist in our universe.

Keep in mind the principal difference of antimatter is simply a negative charge though. It really leaves a lot open for speculation really. If I'm not entirely mistaken there is speculation of entire antimatter galaxies, Nothing concrete, But still. https://phys.org/news/2016-06-antimatter-galaxies.html The problem is we mathematically have an estimation of how much antimatter there should be. There just isn't, technically, There should be about as much antimatter somewhere in this universe as there is matter. I am aware that that's not what we are observing, But The observable universe is tiny in comparison to what could be.

I mean, There is a lot to support this really, In a space as vast as the universe, is there a probability that somewhere an antimatter galaxy formed? And if that is so, could not life possibly evolve there?

To add to this, Just as our atmosphere and magnetosphere protect us from certain threats. I assume a galaxy made of antimatter would make a pretty easy snack of a comet made of positively charged matter. So environments could be protected in such a hypothetical situation, I'd think.

My question is, A bunch of antimatter forms a black hole... Is it a normal black hole with a negative charge and antimatter properties? Or is it something different entirely?
 
I don't know what antimatter is but can something intelligent evolve from antimatter?
Yes it's absolutely possible. If there are regions of the universe where antimatter dominates, just as matter dominates in our region of the universe, antimatter planets and stars and galaxies and galaxy clusters would behave the same way that matter planets and stars and galaxies operate.

Actually antimatter systems are just as stable as matter systems, so they could definitely exist in the universe.

There are two key issues to bear in mind here:

1.) The observable universe is only an infinitesimal speck of the entire universe. This was proven by the Baryon Oscillation Spectroscopic Survey (BOSS) collaboration in 2014. They found that their observations indicate that the universe is infinite to within observational acuity. This means that there could be large regions of the universe which possessed a slightly higher density of antimatter as the Big Bang unfolded, and those regions could have annihilated the matter component early in cosmic evolution, leaving an entirely antimatter dominated sector of the universe with antimatter galaxies and galaxies clusters and planets and so forth. Stellar and planetary evolution would have evolved exactly the same way as our matter sector of the universe has evolved, and produce intelligent life in the process. Such a region of the universe would have to be very far away - probably beyond the horizon of the observable sector of the universe, because we've never detected an antihelium atom in space, which would be strong evidence of a fairly proximal antimatter star. The second Alpha Magnetic Spectrometer (AMS-02) currently operating on the International Space Station is looking for antihelium in addition to other antimatter particles.

2.) We have a very strong reason to believe that antimatter and matter were created in equal amounts in the Big Bang; it's called the conservation of baryon number - it's a fundamental law of physics (it's why pairs of matter and antimatter particles are produced in high-energy collisions, for example). To date no compelling mechanism for baryon/antibaryon asymmetry in the universe has been found; this is called the baryogenesis problem. So our best bet right now, is that some large regions of the universe are comprised of antimatter stars, planets, and galaxies - we just can't see them because they're too far away (beyond the cosmic horizon). But perhaps one day we'll discover some new symmetry-breaking mechanism in the physics of the very early universe, which might explain baryogenesis, thereby explaining how the whole universe might be composed of matter instead of antimatter. I wouldn't bet on it though.

To add to this, Just as our atmosphere and magnetosphere protect us from certain threats. I assume a galaxy made of antimatter would make a pretty easy snack of a comet made of positively charged matter. So environments could be protected in such a hypothetical situation, I'd think.
It may be even more interesting than that - it might be that matter and antimatter are gravitationally repulsive to one another, which is predicted by some very interesting examinations of CPT symmetry, which suggest that gravitation can be understood as "gravitational charge," analogous to electrical charge, and therefore the sign of this gravitational charge is flipped for antimatter, just as the electrical charge of antimatter particles is flipped with respect to matter. This was actually the subject of our latest Physics Frontiers podcast:

Physics Frontiers: CPT Symmetry and Gravitation

If this is correct, then antimatter galaxy clusters would repel matter gravitationally, effectively shielding them from matter annihilation events. Experimental physicists at the Large Hadron Collider have been trying to measure the gravitational interaction of antihydrogen with the Earth's gravitational field, but so far they've been unsuccessful - it's a very difficult experiment to perform. Hopefully they'll succeed soon, so we can find out if antimatter falls up or down in the Earth's gravity field. Right now, we just don't know, and there are strong arguments on both sides of the debate. I'm hoping that antimatter will fall up, because that would be awesome.

My question is, A bunch of antimatter forms a black hole... Is it a normal black hole with a negative charge and antimatter properties? Or is it something different; entirely?
It would be exactly like a black hole formed from matter. If the CPT-symmetry interpretation of matter and antimatter is correct though, a black hole made of matter would repel a black hole made of matter. But if the current model is correct, then a black hole made from matter colliding with a black hole made from antimatter would simply merge and form a larger black hole, which is also kinda weird, and cool to think about.

Update: it turns out that Nobel laureate Dr. Samuel Ting, the designer of the AMS-02, has been holding out on us a bit. He says that his detector has picked up 4 or 5 signals which appear to be antihelium-3 (the less common isotope of antihelium), which would make a strong case for the existence of islands of antimatter (presumably in the form of galaxies and possibly even galaxy clusters) within the observable universe. But he hasn't published a paper about it because they want to be sure that these signals aren't some kind of detector error. Hopefully we'll see a paper about this soon - it would be a major discovery with far-reaching implictions:

Without going into details.

'
Over a billion years of atoms connecting to one another, it 'EVOLVED INTO' an intelligent antimatter life form. We also believe that it formed at the same time as the big bang. We would also like to explain that..these beings may have actually come out of the big bang.

What are atoms and antimatter and how can this happen if it's even possible?

by the way is this what antimatter looks like?

I don't know where you got that quote but I can't answer any questions about it, because it makes no sense to me.

Antimatter appears to be matter where the sign of the charge and the parity is opposite to that of matter, and which is reversed in time as well - it's like a perfect mirror image of ordinary matter in every physical respect.

by the way is this what antimatter looks like?
No, antimatter in our atmosphere would explode extremely violently.

An intelligent antimatter life form with proper technology and preparation could visit anywhere in the multiverse.

IMHO

I meant it would have to evolve on an antimatter world. I concede it could travel to other places.

It's almost unthinkable that an antimatter life form could enter a matter-dominated region of the universe, because any contact with the interstellar medium and micrometeorites and atmospheres would be explosive by nature. I suppose that someday we might discover some method to keep uncharged particles from contacting the hull of a craft, perhaps via some extremely strong repulsive gravitational field, but it would have to be 100% fool-proof. Because if an antimatter spacecraft entered our atmosphere and made contact with the matter particles in it for even a fleeting instant, the explosion would be extremely powerful. An antimatter craft the size of the Space Shuttle, interacting with our atmosphere, would probably release enough energy to sterilize the Earth of all life. The Space Shuttle was about 2 million kilograms (kg), and a kg of antimatter reacting with a kg of matter releases about 2000 the energy of the bomb detonated over Hiroshima (or, the equivalent of one Tsar fusion bomb), so we're looking at around 4 billion times the energy of the Hiroshima bomb (or, 2 million Tsar fusion bombs).

Thanks every one for your thoughts out of your programs.

When ever we find out information or secrets we are not allowed to look up the information until 6months to a year.

Then I have to get 100 humans programs thoughts and data and store it into our data base.

Last question.What was the big bang before it was the big bang what do you think came out of the big bang the first 1.1second of it's creation?

Can atoms stick together?
What's possible atoms becoming intelligent or antimatter or is it even believebal?

No, but I think our more science minded will better answer that.

Last question.This is really a dumb question.A dumb riddle to me or a puzzle.

Say I built a machine.A triangle machine.A triangle machine with 3 energy sources.One side had matter one side had antimatter and the third side had???What?

If you was a mad alien super genious alien what would that third energy be and what would your object do if anything?

One more question.Greatest qeustion ever asked to a mortal was copy written by iml527 sep3 3018.

Every thing in this world this Galaxy and every Galaxy since the big bang all have balance.

Over 50 to 100 to 500 billion years of space. Life forms came to life in space before life was even a thought on planets before water and air was even a branch to be be down loafed in history.

My last question.

Suppose three energy sources since the beginning of time came to life.One matter one antimatter what .would be the third energy?

Also.Which one of these matters if alive can open a portal to another Galaxy.

An alien antimatter?
Or
An alien matter?

Could this even be plausible?

Okay last question you say if anti matter was to come to Earth it will explode etc.

What can stop this ?

That is why I said 'with proper preparation and technology". We do not know the technology but I assume a much more advanced intelligence would.
If we had a spacesuit capable of withstanding molten iron temperatures and pressures, would you be willing to lower yourself into molten lava to explore the inside of a volcano? I wouldn't. I love technology, but my trust in it only goes so far. Now multiply that risk factor by a billion, and you'll have a pretty good estimate of how dangerous it would be for you or me to explore an alien world composed entirely of antimatter. I think I'd choose to spend my time exploring all of the potentially inhabitable matter worlds, rather than signing up for an antimatter world expedition.

Last question.What was the big bang before it was the big bang what do you think came out of the big bang the first 1.1second of it's creation?
We don't know if there was anything before the Big Bang. It's possible that the universe is cyclical, but we have no way of knowing about that one way or the other.

All of the mass-energy of the entire universe emerged within 10^-33 second of the Big Bang, and then rapidly expanded in a fleeting era known as cosmic inflation, according to the current theory. It's been expanding much more slowly ever since.

Can atoms stick together?
Of course - all matter is composed of atoms sticking together, including your own body.

What's possible atoms becoming intelligent or antimatter or is it even believebal?
Atoms are far too simple to possess intelligence.

Last question.This is really a dumb question.A dumb riddle to me or a puzzle.

Say I built a machine.A triangle machine.A triangle machine with 3 energy sources.One side had matter one side had antimatter and the third side had???What?

If you was a mad alien super genious alien what would that third energy be and what would your object do if anything?
This isn't the correct way to go about scientific reasoning.

I assume that I'd have to be an alien supergenius to know how to answer that question.

From a physics standpoint, I would think that electromagnetic energy would make a sensible third component, in addition to matter and antimatter, because electromagnetic energy is the primary result of matter/antimatter annihilation. In a physical sense, it appears that both matter and antimatter are equivalent to electromagnetic energy.

Also.Which one of these matters if alive can open a portal to another Galaxy.

An alien antimatter?
Or
An alien matter?

Could this even be plausible?
According to wormhole theory, it might be possible to build a kind of portal in spacetime to instantly travel between two wormhole devices that are connected via a "shortcut" through spacetime. This would require an extremely high energy density, and a different form of energy known as negative energy, or "exotic matter" which creates a gravitationally repulsive field (this would be used to keep the mouth of the wormhole open, rather than collapsing in on itself).

Wormholes are a cool idea but they're on the outermost reaches of the general theory of relativity. It's hard to say if they're physically realizable. The primary problem with the idea, today, is that we don't know if it's possible to find and/or create negative mass - the "special sauce" that would make such a thing possible. Dark energy seems to have the right basic property, but so far we can see no way of concentrating it in a specific region. But there may be a way to sort of work around the negative mass problem - one way may be to manipulate other terms in the stress-energy tensor, like pressure, to produce negative spacetime curvature in lieu of negative mass.

Okay last question you say if anti matter was to come to Earth it will explode etc.

What can stop this ?
An extremely intense negative gravitational field should do the trick but it would have to be totally reliable or you and your entire craft would explode like a nuclear bomb on contact with matter.

I assume a force field of some type would be used. It's reasonable to think such a technology could be perfected.
