If the universe really is expanding then why can we not see energy still expanding out from the center?
Scientists say its still expanding...so why is the center not continually spitting out energy ;left over from the big bang

answers:
say: HUBBLE SPACE -TELESCOPE.
yes. you can see the energy
HUBBLE -SPACE TELESCOPE.

Jeffrey K say: The Big Bang was not an explosion of matter/energy in empty space. This is a misconception most people have.
The Big Bang was the creation and expansion if space itself. Galaxies are not moving thru space. The space between them is expanding.
One way to picture it is that we are on the 3D surface of a 4D hypersphere that is expanding. Our 3 dimensional hypersurface has no center because the center of expansion is the center of the hypersphere in 4 dimensional hyperspace.
(Experts will notice that this leaves out lots of details and is not precise. But this is the basic idea.)

Cowboy say: Every part of the universe is the center and if we see matter, we see energy.
-
Ronald 7 say: That energy has been spent making Stars, Planets, Galaxies and the Universe as it is there is no sign of the centre, it is long Gone
Just like some being 12 Billion Light Years away would be asking the same question
That Energy is all around us in the Cosmic Background Radiation and it is the same everywhere
To put it simply, we need Energy to Move, to be
Just like the Universe needed Energy to begin
Energy is never lost, just Utilised
-
Tom S say: Because there is no center, or all points are the center, either way works.
-
YKhan say: The universe is 4 dimensional, therefore the center exists in space & time at the Big Bang. We do see energy emanating from that center, it's called the Cosmic Microwave Background Radiation. That's the remaining energy of the Big Bang, and it's visible in the microwave region of the electromagnetic spectrum.

Joan H say: You can't see energy. You can only see if energy is reacting with something.
-
Nick N. Ame say: To understand how the Universe is expanding you have to imaging a balloon expanding. You can not draw an arrow on the surface of the balloon pointing to the centre of the expanding balloon. Likewise you can not look towards the centre of the Universe to see it expanding.
-
Nyx say: The expansion of the universe occurs everywhere - there is no center.
Or, look at it this way - We're just as much at the center of the universe, as someone else is 14+ billion light years away. The cosmos creates its own space expansion.
-
L. E. Gant say: There IS no centre!
However, there is a Great Attractor....
Anyways, the energy left over is all around us.
-
duke_of_urls say: The universe is expanding, but it isn't expanding from a center. Instead, the universe is expanding everywhere.
Simply put, the expansion of the universe is a four-spatial-dimensions expansion, not a three-spatial-dimensions expansion like an explosion from a center. One has to get beyond three-spatial-dimensions thinking in order to understand the idea of the expansion of the universe.
-
Landon say: The reason we can't see the energy is because it's like big @ss, expanding in a way we can't see
-
CarolOklaNola say: Because we have NO IDEA WHERE the center of the Universe is WHY.
YOU ate at the center of your own private unique subjective universe you share with NO other purpose. Human beings seem unable to agree on what coordinate system to use. Many don't understand the CONCEPT of a coordinate system. Multiple locations on Earth can be "home" fir YOU at the same time. Home is where YOU sleep most of the time.
I no longer know where home really is anymore. My current apartment is temporary. I may die in this apartment.
You can curse and insult me and anyone else as much as you want. That is not going to change the FACT that we have NO IDEA where the center of the entire SLOWLY expanding Universe is. The Hubble constant is NOT a speed and it is NOT constant.

PhotonX say: Here; I'm not a big fan of Copy/Pasting, but I just answered a later pretty-much identical question before I saw yours (that's the downside to looking at the most recent questions first), so here it is:

Chris Ancor say: If there was a centre no one knows where it is, or where it was.

? say: Most things scientists say, I doubt, like I don't believe they know what they're talking about, and they're just sort of stating their unproven hypotheses as facts. Einstein's cycling universe paper was suppressed by the church until five years ago in English. He came out with the Einstein/DeSitter version of a monotonically expanding universe, a year later, however he got death threats for saying in his books that Christianity was stupid, and he favored Buddhism. It was taken as proof of the literal truth of Genesis, by scientists when a Catholic priest came out with the big bang theory.
Simple fact is, we don't know what dark energy is, in my view it's energy, like any other, we just can't see it and measure it. Stars push out energy, everything gets sucked into black holes, including that. My view is it's as simple as black and white, up and down, stars and black holes, energy and mass. The black holes suck in all propulsion, leaving only gravity as a force, they turn around in orbit, and come back down, no matter how long it takes, or how far or fast they have traveled, and they would have ten times more gravity, from the dark energy converted to mass, in the black holes.
They got it wrong, they been held back by Christianity corrupting science, here's a supporting link. BTW, there is a center of the universe, as opposed to the known universe, it's where the big bang happened, and always happens. It's a sphere, not a circle, why would you not recognize the universe is in three dimensions? The other side of the universe is travelling away from us, at faster than the speed of light, that's the other side of the center.
