✳ This is it ... the scientific topic we always wanted to discuss ...

[RayDunzl]

You think our planet will still be orbiting the Sun in one billion years?

REGINA I speak for the President of the United States. Now please tell me why have you come to our planet.

KLAATU Your planet?

REGINA Yes. This is our planet.

KLAATU No. It is not.

Time Travel

https://www.sciencealert.com/a-physicist-has-come-up-with-the-maths-to-make-time-travel-plausible/

Well now this totally explains why expensive headphone cables sound better versus basic cables. Must be some kind of electron time travel effect.

That doesn't sound too promising.

uh, yes? a lot more than that, actually.

 

[North_Sky]

So the Sun would survive another billion years?
...With all those inventions we build on planet Earth?

 

[North_Sky]

How old is the Sun? -> 4.603 billion years
How old is the Earth? -> 4.543 billion years

 

[North_Sky]

How old is the Moon? -> 4.53 billion years

How old is the Universe? -> 13.77 billion years

How old is Humanity?

"While our ancestors have been around for about six million years, the modern form of humans only evolved about 200,000 years ago. Civilization as we know it is only about 6,000 years old, and industrialization started in the earnest only in the 1800s. While we’ve accomplished much in that short time, it also shows our responsibility as caretakers for the only planet we live on right now."

Lots of time travel to catch up ...

Perfect; this one then is specially for you ...

Take all the "time" you need ...

Oh thats easy they talk about billiard. I like.

Nobody here mentioned the Time-Space GPS used in Avengers Endgame to safely and accurately travel through time using the quantuam realm ?

The sun cares a shiit of what ever gimmicks we build on earth.

I remember when the universe was less than 10 billion years old. How time flies.

 

[mansr]

No more than mentioning "the sky is blue".

The sky is blue, and it's the the government's fault.

Indeed Sumerians in Mesopotamia dated 4000 bce used to be known as the first civilizations but Gobekli Tepe is considered to be 12,000 years old with stones weighing 10-20 tons and one stone still in the quarry weighing 50 tons. In the grand scheme of things that's still a cosmic second in relation to the age of our planet

You could drop the entire Earth into the sun and it would have little to no impact on the sun itself.

The average lifespan of a yellow star is estimated to be 8-10 billion years, at which point it expands into a red giant (and will consume the inner planets). It will likely last another 5 or so billion years in that state before eventually collapsing back into a white or brown dwarf star.

Oiltanker vs. fly.

Was the margin not wide enough?

hahaha, nice Fermat's Last theorem reference.
I had to call it out explicitly, spoiling the fun.

Average longevity of a mammalian species is roughly 2.5 million years. We have a ways to go, but not long at all on astronomical time scales.

You play snooker too?

Still talking about that Red Dwarf episode?
