This is true. You should be comfortable with syntax, sorting algorithms, matrices, and writing simple programs by now. The only thing you should be studying is the case example that you'll be tested on the exam. It's possible to goof off and only study one month before the exam and get a five, but any later is pushing it dangerously close.

Is it possible that the Big Bang theory is wrong or incomplete?

What would've caused a point of infinite density to explode, seemingly for no reason?

When black hole reaches a critical mass and the matter within the singularity loses its material cohesion, it will transform into pure energy virtually instantaneously and cause a new 'bubble' of space. Our 'universe' is only one of many and acceleration of the expansion of the universe is due to outside gravitational/electromagnetic forces.

Atleast thats the most logical explanation i can come up with since i dont believe in hypothetical dark memes.

Hey anons. I really want to make a YouTube channel that focuses on different topics such as Science, Religion and Philosophy. I know that I have the skills to create this. I am professional video editor, so I can edit my videos without a problem. The topics I talk about are interesting to the intelligent folks. My looks are decent. Basically I am capable of creating a YouTube channel. But I have a question. Do you think there are too many science focused channels already? Will mine be unneeded in such a big pool of other youtubers?

TLDR: Is YouTube overfilled with Science channels?

you can assume n=k, so prove n=k+1 is true using induction.

>Want to advance science
>Don't want to advance humanity

I never publish any of my results, I never use my knowledge to help my community. I work as a very simple and easy laboratory worker so I can devote my entire energy to science.
Sure I would love to be rich and famous, but I hate humans more than I love myself so this is fine.

Who else /bystander/?

Why is hating everyone and loathing humanity such a meme at this point? Instead of berating your peers, why don't you actively try to be the change you want to see? Really, what is loathing your species going to do for you? You were given great potential being born as a human, why not use it to actively improve humanity instead of hating it from a distance?

Non-renewable resources don't exist... Its all a matter of how much energy you are willing to spend to reuse them.
And when energy costs become prohibitively high, you can also find alternatives.

How much energy do we have then? Solar and wind are unreliable, and as of now inefficient, aren't they?

if a company copyrights a music/video file that is essentially a binary number is it illegal to own that number? Could I justify sharing a 1 bit shift of that number. What if The bits of a drake song in a particular compression correlate to a universal constant and it becomes illegal to own that number? What are sci's thoughts of forbidden numbers?

Is rape just crime about putting certain atoms too close without consent of that atom?
>>
>>8878018
I think it's just a reductio ad absurdum fallacy. You say "forbidden number", and then everyone thinks "oh, how dumb it would be if you weren't allowed to share the number 1031242895", but in reality, the numbers you are talking about have millions (song) or billions (movie) of digits, so there is practically no chance of someone just arriving at them at random. The artists put work into creating those digits, and they deserve to have the ability to sell their product without others copying it and distributing it for free.
You wouldn't be justified in sharing a bitshifted copy of it with the intent of letting other people then turn it back into the original, just like you aren't justified in sharing an encrypted or zipped version.
The bits in a drake song couldn't correlate with a physical constant, because physical constants aren't measured to millions of digits of precision. If for some strange reason the bits correlated with a mathematical constant, like e, they wouldn't ban calculating that constant, because that would be absurd. The artist would be in a really shitty position, because anyone could just download a program that calculates the digits, but so what, his fans would still buy his music, so nothing of significance would happen.
>>
>>8878018
No, it's not the binary that's copyrighted. You could use a different binary format or even a trinary system and it'd still be copyrighted. With that in mind you could reformat the binary code to resemble literally anything else in the world that's binary. Which would mean they could sue anybody else in the world for copyright infringement.

For instance, if you could make a new binary format or encryption that makes a pirated movie appear as Moby dick. Then then the movie's legal copyright owner could sue anyone for owning a copy of the book Moby dick.

For every scientist you find who disagrees with the science of climate change I can find a thousand who agree with it.

http://www.ucsusa.org

Single scientists will have pet theories. Single scientists may have personal agendas or be lured by greed. This is why it's more important to find groups of scientists working together so that the opinions of contrarians will be filtered out.

And by the way you will find no examples of any single body of scientists on Earth who support your claim that climate change is a myth. None.

That should tell you something about the science behind it.
