The Universe Is Disappearing, And There's Nothing We Can Do To Stop It
Forbes ^ | August 17, 2018 | Ethan Siegel

Posted on 08/18/2018 8:10:32 PM PDT by EdnaMode

It's been nearly a century since scientists first theorized that the Universe was expanding, and that the farther away a galaxy was from us, the faster it appears to recede. This isn't because galaxies are physically moving away from us, but rather because the Universe is full of gravitationally-bound objects, and the fabric of space that those objects reside in is expanding.

But this picture, which held sway from the 1920s onward, has been recently revised. It's been only 20 years since we first realized that this expansion was speeding up, and that as time goes on, individual galaxies will appear to recede away from us faster and faster. In time, they'll become unreachable, even if we journeyed towards them at the speed of light. The Universe is disappearing, and there's nothing we can do about it.

When you look out at a star whose light arrives after traveling towards you for 100 years, you're seeing a star that's 100 light years away, due to the fact that the speed of light is finite. But when you look out at a galaxy whose light arrives after traveling towards you for a journey of 100 million years, you're not looking at a galaxy that's 100 million light years distant. Rather, you're seeing a galaxy that's significantly farther away than that!

So that’s it then, we’re all going to die.

It’s the old physics problem about throwing a ball out of the back of a truck.

60% didn’t understand it no matter how hard you described it.

Or, who knows, maybe in another 20, 30 years we’ll have a brand new theory that will tell us something completely different.

If the Universe is expanding, what exists beyond the Universe ?

How can we determine the actual size of the Universe if there are parts of it we can never see or measure ?

The word UNIVERSE means EVERYTHING THERE IS. How can there be anything else ?

Is the Universe round or square ?

This is something that has puzzled me. As we look further out into the universe we are also looking back further in time. It would seem logical to me that if objects further away, that is say a billion light years distant and a billion years in the past are seen to be moving faster than closer objects, that would mean the expansion of universe is slowing, not accelerating.

I know that I'm missing something which supports the idea that it is accelerating, but equally I know that the simple observation that more distant objects are moving faster can't be it.

Yet that's what science writers, you know, the ones who continue to insist Global Warming, err, I mean "Change", is caused by human, err, I mean "American", activities and will kill all life on the planet last, err I mean "next" week. So color me skeptical about their explanation, not necessarily the conclusions reputable astronomers have reached.

Did they have a permit to capture that Neutrino?

It is classified as a endangered particle and subject to federal protection.

97% of the galaxies in our observable Universe are already out of humanity's reach

It's so very lonely.

Once you disappear, you won’t reappear alive again.

Kinda like Jimmy Hoffa.

2 actors who reads words and haven’t a clue? Might as well ask 2 lawyers. They lie for a living too.

"It is classified as a endangered particle and subject to federal protection."

There is no shortage of neutrinos:

50 Billion Neutrinos Pass Through Your Body Every Second

"There are fifty billion neutrinos passing through your body every second. Which means about 300 billion will have gone through you by the time you finish reading this sentence."

Just not something a rational person should worry about. That won’t stop the Left from trying to legislate or fund raise with it.

That one was 4 billion years old

Got a permit?

Infinite.

Scientists have proven that the universe is finite because they know they can never measure it.

“Darn you, Entropy!” Enthalpy also loses in this scenario.

ps
When I worked for the VA my tagline said, “Management is proof of Entropy” I had it for years until someone in IT knew what entropy was and they made me change it.

We thought it would go on and on,
But now the universe is gone.

95% of the universe is dark energy and dark matter that we cannot observe visually. But physicists know it is there because they can see other evidence of it.

We can call it the unseen realm.

So the atheist who insists that there is no God is indeed a fool, for he cannot see 95% of what exists - and yet he insists he knows what is not there in what he cannot see!

And yet the invisible evidence of God’s existence is everywhere, just like dark matter and dark energy are there for the physicist.

As a scripture somewhere says, God is a God who hides Himself.

How infinitely wise He is.

Exactly, which most likely makes it infinite. Nothing else makes sense.
