What the heck is pulling us and our whole group of galaxies towards the constellation Leo?

at 400 miles per second. It can't be near by or it would be pulling some galaxies harder than others; and it would have to be very very large (e.g., a thousand times larger than our galaxy)!What the heck is pulling us and our whole group of galaxies towards the constellation Leo?The Great Attractor! It's likely a massive group of galaxies hidden behind our own Milky Way:

My guess would be that observational error or misinterpretation of the data accounts for a lot of it. I like the universe to be less complicated and I don't like the idea of profoundly massive unobserved unknowns out there...What the heck is pulling us and our whole group of galaxies towards the constellation Leo?
"Hidden group of galaxies" directly in our sight-line or something like that? Wouldn't such an enormous localized gravitational source have measurable effects; not to mention bending space, and light with it so that it would be visible no matter where it is, at least in the X-Ray spectrum?

What the heck is pulling us and our whole group of galaxies towards the constellation Leo?Titou-I'm certainly no expert. What I know is that the movement was shown as a slight Doppler effect on the background radiation, making the microwave light slightly "bluer" toward Leo and "redder" in the opposite direction.

In deducing the presence of the Great Attractor, scientist have taken the cosmic microwave background as the absolute standard of rest. So far the only explanations I've seen have to do with gravitational pull, but who really knows....hence, my question.

What pulls anything towards anything? GRAVITY!



But maybe are not being PULLED?? Maybe we are being PUSHED! Is a bullet fired from a gun "pulled" towards the target? NO! It is PUSHED by the force of the exploding gunpowder.



Now, what kind of explosion could push a whole GALAXY towards another one? It WOULD have to be a really BIG explosion, wouldn't it? And that would make a really BIG Bang, don't your think?



Get it? Big Bang . . . . .



We are not being PULLED, We are being PUSHED by the forces created during the big bang. We SEEM to be going towards Leo because Leo is moving slower than we are.
I believe that the dark energy which pulls us, comes from dark matter which surrounds the membrane of our universe. A negative pull which is greater than the positive gravity inside the membrane. Hence the universe is expanding, being pulled outward and the galaxies are speeding up the closer they come to the event horizon.What the heck is pulling us and our whole group of galaxies towards the constellation Leo?
Pamela Sue Anderson? She seems to have disappeared from sight.



Edit: But seriously. I'd say that it is because the Universe "breathes", and what we are measuring are the local effects of that.
The physics of subspace, which have not yet been discovered. Don't worry, Zephram Cochrane will figure them out, and humanity will have Warp Drive starships. But we must be patient.
