Just awesome! After seeing this, I reconsidered my place in the universe once again. Now I recognize that my hands are not that small, Enes Kanter is not that huge, Gobert is not that freak, PKM is not that short, bigb is not that big, Archie is not that tall, dalamon is not that skinny...

Orengello is still orange though.

Reconsider yourself. And thank God for everything.

(It took 6 days for him to make all of this, ten thousands years ago)
 
Wow, that makes me feel even better, seeing the scale of the universe, and knowing that I am still the center of it all. :)

And can you believe that all of that revolves around the earth? Amazing!

So this shows us which stars are the biggest, but does that equate to brightest?

Technically speaking yes, the earth indeed is the center of the universe. But in fact, every single point in the universe is exactly the center of the universe, so it's not that special.

Your question is relative. For us, brightness is most likely about the distance. Sun is quite a modest star but it's the brightest, right?

On the other hand I don't know if the size is the first factor for brightness even if we suppose them on equal distances. Probably the type of the star would be the determinative factor for the brightness, but I don't have much knowledge to talk surely.
 
The answer was no it doesn't.
 
props ectya

A youtube science binge was the perfect thing for me and my daughter to do on a rainy day.
Thanks

Thanks heyhey.

Here is a nice video I watched just a few days ago that eventually triggered this thread because I too went lost on youtube for a science binge.

It's about Al Jefferson, I mean, black holes. What would it be like to travel inside a black hole? It also refers to the center of the universe topic I mentioned earlier in this thread.

and not only that, but there's ALWAYS room for gello!!!!


an amazing concept, really, if you think about it...

Ahh, more shiverings! The universe is amazing.

Though I generally prefer some baklava or sütlaç(rice pudding) afterwards.
 
I don't buy into the whole universe is expanding thing quite yet.

It seems to me that the evidence(that light from other galaxies is red shifted)could be explained by other phenomena that do not require dark energy. For instance, a red shift can be produced when light passes through certain gasses. Dark energy is a tough pill to swallow which is why I will keep an open mind towards alternative theories that may explain a redshift in the cosmos.

I am not saying that the universe isn't expanding I am simply saying that it might not be.
 
I may just be playing mad scientist but..

It seems more likely that we do not fully understand light and that there may be a natural frequency decay for photons. As opposed to an elusive energy source that is everywhere , strong enough to push galaxies apart, and have no measurable effect on stars planets and people. The amount of Dark energy required to push galaxies apart at the rate required to explain the observed red shift is more than all other sources of energy in the universe combined, and noone has a good idea as to where that energy comes from.

I'm open minded too about it. Actually I'm open minded about every modern theories that isn't proven with pure mathematics. For instance I have no doubt that prime numbers are infinite because it can be proven with pure math in a single line.

On the other hand, the nature of physics science requires open mindedness regardless. A few months ago I was reading a book that touch upon Bernoulli's principle and fluid dynamics and it is remarkable that even basic physics had to pass through countless renovations until it can attain a certain degree of certainty.

However, the consensus about the expanding of universe is very strong among the modern scientists. To be honest I believe it's the truth. Because the doppler effect(redshift, blueshift) has a strong ground in Astronomy. Many calculations and observations are based on this effect and the accuracy of the results are way too consistent for it to be from variable causes such as certain gasses.
