THE SHOW MUST GO ON

Redshift over cosmic scales: Anyone here know if it makes events appear to last longer? For example, if we measure an event to last exactly one second in our galaxy, would an observer 13 billion light years away also measure it to last one second? Seems like if the light 'stretches' from blue to red then the 'total length' of the light waves that are observed would need to increase too, right? Since the length of the wave increases, it would take longer to pass through the far-away detector, which would appear as a longer event.

Anyone know, and if there are any megabrains here, do you know by how much the time of the event would increase by? Since we're talking nanometers of shift from blue wavelength to red, it seems like it would be a very small increase, right?

Meaning is that which gives existence/consciousness/being a purpose, a reason to continue going on that is not fundamentally dependent on the material parts (atoms, energy, and such) that compose it.

In the next 30 years, the Bohmian interpretation of quantum mechanics (aka "pilot-wave theory") will become more popular with professional physicists than either the "Many Worlds" or the Copenhagen interpretations.

Prove me wrong, dummies.

What exactly is "applied-ish mathematics"? Whats your PhD in? I work at a consulting firm that does human factors/cognitive ergonomics... and there are math peeps working here. What, specifically is your degree in, and what did you do before you were unemployed?

How is that funny? Grown men are fanboy'ing over Tao as if he Justin Timberlake in the 90s. Tao could comment "I took a shit and I can prove it." and he'd automatically get 100+ upvotes/likes. This is one problem I have with the field of modern mathematics, that it is reduced to fads and celebrity worship.

For example, Joel David Hamkins suffers from this as well as evident by his blog post: http://jdh.hamkins.org/mathoverflow-the-eternal-fountain-of-mathematics-reflections-on-a-hundred-kiloreps/

He once joked that tenure/promotional consideration should take into consideration ones MO points.

Look at any top school in math. Most will be overrepresented with specialist in the same areas of mathematics, why? Because it is "sexy". When was mathematics ever about being sexy, cool, or a celebrity?
