  • And in 2011 scientists have proven him wrong...

  • If i watch a bullet travel further and further it will eventually dissapear due to space + gravity ending up on the floor somewhere ahead of me. I believe that same concept applies with space. It ends up settling on the floor somewhere evolving until it is eventually gone over time.

  • Everything in the video is based on the premise that the Universe contains a FINITE amount of matter and energy, which is why no one can figure out the source of this "dark energy" causing the acceleration of the Universe's expansion.

  • if the universe is expanding, is it possible to tap in to the enrgy that drives that expansion?

  • I'm too lazy to research on my own right now so any body can answer

    since the (moving away)galaxies are so far away from us we are actually looking at the past, could it be at the present the universe is contracting right now? can we know?

  • @ixataca, I probably don't know much more than you do on the subject, but I would suspect that because some of the galaxies we're observing aren't that far away from us, it's probably still expanding most everywhere.  But I think it's a great question nonetheless.

  • If the universe is expanding, why are the stars in the same positions, relative to each other, as they were thousands of years ago: the constellations are the same, why?

  • @stopdemockery maybe they are gravitationally attracted into groups, and just the space between constellations grow.

  • @xxxslayerxxx666 ~ In that scenario the groups of stars would have moved trillions of miles away from each other over those thousands of years, impressively changing the constellations. It's the same result. The fact remains that the constellations look the same as they did thousands of years ago. Why? It's because they haven't moved an inch.

  • @stopdemockery so are you implying that only the space between galaxies are expanding and not the space between the stars in our galaxy? or that the whole expansion idea is myth?

  • @xxxslayerxxx666 ~ My guess is that universal expansion is a myth. No other answer (of which I am aware) satisfies the constant constellation question.

  • @stopdemockery but then how was it created, how could there be a nothing, maybe it's just comes from parent universes, so it would be like how there was no me before i was born, cause you don't just come from nothing. So the universe has to at least be able to reproduce....but it still doesn't quite answer the big question where did all of matter come from in the first place, well, i have no freakin clue! lol.

  • @xxxslayerxxx666 ~ Perhaps it expanded to a point of equilibrium, and remains balanced against the push of dark matter and the pull of gravity. We're just daydreams in the mind of God. But, the Earth is becoming his nightmare.

  • @stopdemockery the reason they don't look like they've changed is because they are so freaking far away. The farther away an object is, the slower it appears to move. The same thing happens to the scenery in the background when you're driving your car. It's basic trigonometry!

    Do you have even a remedial grasp of how large interstellar distances actually are? or how about the size of the Milky Way. The distances are mindbogglingly huge.

  • @TheHomelessCripple ~ Let's examine my "remedial grasp" of the situation. Likewise, the speed at which these objects are supposed to be moving away from each other is equally mind-bogglingly enormous. So, you're saying that if two objects are moving away from each other at light speed, in a thousand years they would appear (because of our great distance from them) to have not moved at all? 

    Your theory is utterly unacceptable!

  • An interesting article in New Scentist about Horava-Lipschitz gravity may be worth a read, it could answer everytihng.

  • @Neutrinoghost EDIT: Hořava-Lifshitz gravity (Petr Hořava - University of California, Berkeley)

  • no, no, no... it's turtles all the way down!

    Actually, the red shift and background noise could play games with us. We build huge theories on them, and once more it turns out wrong. We live in the dark ages of science. Dark energy, dark matter and to top it of, black holes.

    99.9% of known matter is in the form of plasma. And where is electricity in these equations? Some very interesting theory emerged. Look up: The electric universe, thunderbolts from the gods

  • the is a huge mass concentrated somthere...

    so it makes us move faster and faster then we moving toward.

    in other hand there is ecseleration.

    gravity law saying rhat force proportional to mas divide by distance squre

  • Start with one wrong assumption and everything after that doesn't add up, normal gravity doesn't slow the expansion it causes the expansion! Gravity attract at an accelerated rate, it takes energy to move a mass, gravity moves everything, in energy exchange the universe expands at an accelerated rate exactly opposite and equal to the attractive force of gravity, it's the law of conservation of energy. There was no big bang, there was a hunch if everything was moving out it must be like a bomb

  • That is a small lecture hall lol, good video!

  • I have a question. An often quoted analogy to describe the expansion of the universe is that of an expanding balloon, with points on the balloon representing galaxies. As the balloon expands, the points recede from each other, but doesn't the 'unit' of distance also expand with the balloon, so that the 'distance' between points remain the same? Can anyone care to enlighten me?

  • @maxwellsdaemon7 the fact that the balloon is expanding doen't mean that the units we measure the distance in does expand, for example 1cm is not gonna be expanded to 1cm expanded 2 times. when you blow up the balloon for example we don't say the volume went from 1L to 1L that expanded 2 times because that basiclly means 2L......... just think of it as the ruler or device you measure the distance in is a totaly independent system.

  • lol but if you call this something in empty space aether someone will always say no no aether was dismissed long ago. Careful though if we figure it all out and lift the curtain we might find a circus monkey is running the show.

  • What would happen if the Universe were infinite? Taking any spherical volume, and comparing its volume to the surrounding shell equal in thickness to the sphere's radius, you find that the volume of the shell exceeds that of the sphere by 7 times. Therefore, assuming galaxies strewn throughout the Universe, each shell into infinity would pull the interior sphere outward by gravity. F = ma means that all parts of an infinite Universe must accelerate and expand. No requirement for dark energy.

  • Funny how Nature made space out of all the DEAD!

  • Is there anything currently  at the geometric center of expansion?

  • There is no geometric centre of expansion.

  • Sure there is..... draw a dimensional vector from every galaxy along its path of motion, correct for gravitational interaction, and if there was an originating "bang", the vectors should mostly intersect at what we'd call the "center of expansions".

  • @planetdarwin

    I know this is 6 months late, but you can't really do that because the observed direction of motion for a galaxy is dependent on where you are observing it from. <.<

    If you just observed from the Milky Way, then you'd think the center of expansion is the Milky Way. But it isn't. In reality, the center of expansion is *everywhere*. :D

  • Einstein was wrong and we are right! LOL! This from people who say they don't know what dark matter is and that it is ALMOST uncomprehendible. That is an absurd statement!

  • he's right if you forget the term of conservation. or if your math does not factor us flinging though space, circling a star and spinning around.

  • is this about physics or physicists?!!
