The size and age of the Cosmos are beyond ordinary human understanding.
Lost somewhere between immensity and eternity is our tiny planetary home.
In a cosmic perspective, most human concerns seem insignificant, even petty.
And yet our species is young and curious and brave and shows much promise.
In the last few millennia we have made the most astonishing and unexpected discoveries about the Cosmos and our place within it, explorations that are exhilarating to consider.
They remind us that humans have evolved to wonder, that understanding is a joy, that knowledge is prerequisite to survival.
I believe our future depends on how well we know this Cosmos in which we float like a mote of dust in the morning sky.

Let-s go to the seven-day outlook. -
Your daily shades of the sky forecast: -
Monday: Turquoise-
Tuesday: Taupe-
Wednesday: Robin-s egg-
Thursday: Turquoise/taupe-
Friday: Coal dust-
Saturday: Coal dust with chances of indigo in the late afternoon-
Sunday: Void

I think we do not live in a simulation, but we try to simulate the reality and therefore assume that we are a simulation. we do not quite understand the universe on the quantum level because our brain was evolutionally designed to look for food and fight for our lives, and not to comprehend abstract concepts.

How do you know the age of the universe while you count its age in earthly years? there was no earth in the very beginning. Also isn't it true (according to relativity) the more you go back in time, time becomes infinite? therefore no beginning?

Still doesn't explain how a finite inflation time can cause (our) infinite size universe? Shouldn't Our universe (universe with our laws of physics) still be finite in size after inflation? Please explain clearly!

the problem with the simulation is irrational numbers, they are infinitely calculable and so would need an infinite calculator. might as well make a perpetual motion machine

What's the difference between the big rip and heat death? They both sound like death by everything floating away from everything else until nothing exists?

What if dark energy it's actually finite and dies eventually (everything has an end, right, that would change everything about the universe future, right?

I'm not shaking Emily, she is very educational, but John and Hank were able to make us pay attention much more just by entertaining us with humor.
