Life, The Universe and Everything (Science Thread)

So I just watch a mind blowing video on black holes/the universe and wanted to share it with you lovely people (see below) but there wasn't really an appropriate place to share it. So why not make a science thread!?!?!?!

I love science, so post everything and anything interesting that we can geek over.

Black hole video: (WARNING: You mind will be blown)

A science thread? I think I will enjoy this....

When its comes to anything science related always start with something that not only blows your mind but also leaves you speechless:

So do we have any professional scientists here, or hobbyists?

Poll - do you get paid for science shit?

Big yes from me.

As a kid I was a big hobbyist. I use to do experiments in my garage... just stupid stuff like seeing what was an acid or alkaline by combining it with baking soda.

Made a lot of mess.... my mother was not happy.

Geeking so hard right now

This video shows you that it's potentially possible there is an exact replica of you... somewhere...

Cool.
But this is a massive problem with theoretical science; the realities are brushed under the carpet for the sake of convenience.
the idea that you come across repetition is fine, but he just said that the universe is 10^26m3. Outside THAT, we have no reason to expect that matter exists ... just a bogging great vacuum into which the universe is expanding.
So there's a finite amount of matter. Almost certainly FAR too little matter to ever find a duplicate of you.
Mathematicians make those assumptions.
Practical physicists (proper scientists!) don't.

Aaah, I bloody love science.

Honestly, you guy are making it really hard for me to keep away from this forum!

I had my mind blown a few months back by this -

I haven't seen the videos yet since my net connection is acting up. But for the sake of discussion:
...he just said that the universe is 10^26m3. Outside THAT, we have no reason to expect that matter exists ... just a bogging great vacuum into which the universe is expanding.
Assuming, of course, that our universe is the only one. It wouldn't be so far fetched to think of multiple universes the same way we have multiple galaxies and star clusters. Maybe 'our' Big Bang wasn't the only one. :)

Almost certainly FAR too little matter to ever find a duplicate of you.
I don't think that it's a question of the quantity of matter. It's about the odds of carbon based life emerging from another primordial soup with the same set of ingredients (and environmental factors) as in our case. The probability of an event may be one in a million but that doesn't mean that the event simply will not occur twice in a set of ten.

Then again, what is a duplicate? Twins share the same DNA sequence and yet are rarely replicas of each other. And I'm not even getting into behaviour and personality.

Applied science vs. theoretical science is like the dreamers vs. the doers. You need both. It's sometimes good to brush the 'realities' under the carpet :) (I'm not a scientist or even a hobbyist. I'm just curious.)

And I SO need an acoustic dumbhole in my room for when I'm recording! (That sounds like I'm cursing. YOU BIG DUMBHOLE YOU! :p)

The universe is the room the we have available. We're expanding into it. There might well have been another big bang somewhere else in that space, and now they're expanding towards us.
Possible. But the big bang was meant to have been "t=0", the start of time. No time before that. Nuthin. So how could there have been two?
There is a set amount of matter ... only a single bag of stuff that everything is made of. All that matter came from the big bang. So the copy of you would HAVE to come from that bag. The probabilities he was talking about would require a limitless amount of matter. So his argument doesn't hold water.

I don't think that this is anything to do with the chances of life happening. To get your carbon-copy, life would have to begin independently MILLIONS of times. Lots of slime crawling out of lots of soup. I don't buy it.

The dreamers think I stuff then don't worry about it. The doers think about stuff, then worry about how to make it happen. I'm not a fan of the dreamers, I'm paid to be a doer.

Speculation.

Agreed. I haven't seen the video you're referring to so I've no idea what he's talking about.
The dreamers think I stuff then don't worry about it. The doers think about stuff, then worry about how to make it happen. I'm not a fan of the dreamers, I'm paid to be a doer.
What I meant was that people with ideas working alongside the people who apply those ideas is how good things get done. Nevermind. Thread derailment alert :)

Edit:
I see what you did there ;)
