A team of physicists has claimed that our view of the early Universe may contain the signature of a time before the Big Bang.
The discovery comes from studying the cosmic microwave background (CMB), light emitted when the Universe was just 400,000 years old.
Their model may help explain why we experience time moving in a straight line from yesterday into tomorrow.

Interesting read...

Fairly certain I see you from time to time on science related threads..
Here’s fifty cents. Go call someone who cares.
Didn’t get any last night huh?
I always had this theory that the universe would expand (big bang) and then somehow collapse to the infinite, then explode again to it’s limits, contract again etc. To me, that is God’s Heartbeat. Maybe I was right... now the scientists have to work out the fuzzy details...
Ah, if I had THAT answer, I'd earn a Nobel Prize. Not an Al Gore Nobel Prize, but a REAL ONE worthy of respect.
It’s almost easier to grasp a place before time and space then it is to imagine what’s it must be like inside the heads of guys that think this stuff up.
My understanding is that the point is still being debated. Depending on how much “dark matter” is out there, it is possible that the universe will collapse again due to gravity.
Asimov had an interesting theory about this- if the universe contains enough mass to collapse due to gravity, then that gravity is also sufficient to prevent light from escaping. Ergo, the universe is a black hole.
Now that is one to ponder...
1) The universe may have an elasticity to it like water. I forget the name of it, but you know when you pour a puddle of water onto a desktop, and look at it from the side, you see the water has a depth and curves down to the desktop. It has a thickness, but it also retains shape. Same as we dee a drop of water in a spaeship, being round or oblong etc and spinning, but these droplets retain their shape until they interact with something, yes? Well, if the universe were like that, it would expand endlessly until it reached the limit of that elasticity, though it doesn't explain a reason to contract.
Which leads me to 2> Dark Matter. They're discovering many things about Dark Matter, and I wonder: perhaps dark matter has gravitation forces to it. This would allow for elasticity, and could also somehow cause a it to retract, to collapse....
Anyhow, it seems the basic theory of physics would apply to the universe as they would to a puddle of water on a desktop, or a droplet in a spaceship.
Seems to me life is exempt from the Second Law. In order to have an egg to break some animal had to organize random elements into an organized structure of the egg.
What you call elasticity most people call surface tension. I don’t see any analogy between surface tension and the universe.
1.) `surface tension’
I wonder of Wells would have been please or disgusted over how fancy they made his time machine look.
