Does anyone here prefer Analysis to Algebra? I want to like algebra but I seem to suck at it.

Morphological differences have arisen between different populations of humans.

Is it unfair to suspect that there may be some psychological differences as well?

DO YOU MEAN TO IMPLY THAT NIGGERS ARE LESS INTELLIGENT THAN WHITE PEOPLE??? CHECK YOUR PRIVILEGE FAGGOT
>>
>>8920257
Not at all. It is a very sensible conclusion that can be infered from decades of research into human psychology. Scientists have compiled piles of evidence that suggest what we all have thought for a long time: white people are psychologically inferior to all of us. Indeed, so inferior that it is almost wrong to call them human because psychologically they can be classified as mentally disabled and when you think about an entire race being "mentally disabled" then a sensible conclusion is that they could be a subhuman species. Similar to how if monkeys were considered humans, we would say they are severely mentally disabled.

Serious question, if the universe is expanding due to vacuum energy, wouldn't it be possible to harness vacuum energy and (since the universe will apparently expand 5ever or vacuum energy is some quantum shit that doesn't appear to be finite in nature) essentially cheat heat death of the universe?

What is it about death that makes it so final? Is there some kind of phisical law that keeps a being from regaining consciousness ever again or is it just a matter of current technological limitations? Would me bring brought back to life(be it from lets say a scientific experiment or simply the universe reaching a point where some particles are arranged in the way I came to exist in the first place) still be me? I'm not the brightest person out there so please enlighten me.

I'm not one of those guys who can't accept death, the thought that no matter what i'll just end up in a state of permanent rest is quite comforting. What i've been struggling with is the opposite, the thought that my existence is eternal and im in an endless rollercoaster I can't ever get out of. It sounds ridiculous when saying any of this out loud but it's honestly been giving me terrible anxiety that's seriously hindering my life.

Please help?

would the recreation of the ruined laptop with the same particles under the same exact conditions bring that same consciousness back?

Yes. They are just labels for convenience. Labels are constantly in flux. They are updated or removed in response to new information.

Okay, so apparently near the beginning of the big bang, everything was condensed into a singularity (or something similar), and then it all "exploded" away. That's the layman's afaik.

But if all of the energy and mass was condensed into such a small region of space, how come gravity didn't just pull it all back together again? It's not like the shit could travel faster than the speed of light, and the density was practically infinite

Read about cosmic inflation. It really did expand faster than the speed of light.

That's why people talk about the observable universe and the unobservable universe.
>>
>>8923368
How long would it have to inflate faster than the speed of light until all the matter and energy wouldn't be able to condense into a black hole anymore?
And in black holes, even light can't escape, and in a black hole is just a fraction of the mass and in a much larger space, how in the world all the matter and energy be able to escape the gravitational pull, even if the universe expanded faster than the speed of light
>>
>>8923387
One of the most important implications about evidence of faster-than-light expansion is that it's a very strong indicator that the physics which describe now universe almost fully do not accurately describe such a period. So it doesn't even really make any sense to ask why it didn't turn back into a black hole, as we really don't understand why it did anything then (or at least, I haven't heard that there's an accepted model of physics for this time period.

Moreover, the faster-than-light dynamics I think of also as being generally motivated by stemming from the ultra-high-energy small-space physics of the very early universe, and even according to classical physics, gravity usually loses in small spaces. So it's not obvious that what you're proposing should happen would, even under current physics.

Finally, as a last bit of consolation, there is a property of differential equations that for a system which does not obey the conservation of energy, the system's behaviour is time dependent, and vice-versa. So if you want to think about the fact that energy seems to have been created at some point between now and time zero, then the math actually requires that equations which work now do not have to work then at all.

0.999... is the same as 1, so not valid. and c and d are both nonsensical, as you cant have a final digit after an infinite number of 9's, so theyre probs the same as 1, too. so none of them
>>
>>8922164
C) Because B) is 1 so its not on the set, and no C) != B) Because C is finite so is not equal to 1

I want preface this with saying that I have a basic understanding of physics and am in no way an expert, so I apologize in advance if this is completely wrong and stupid.

That being said, I had a question about using nuclear fusion energy for devices such as warp drive engines. Is it possible and what amount energy do you think it would take to power such a device?

nigga we have no goddamned idea how to make one much less how much juice will it take to power it.
that said fusion reactor is hands down the most powerful thing you could possibly have on a ship generating electricity without going for obscure shit like antimatter or fucking portable blackholes or whatever
