If space is expanding at the rate of 186,000 light years per day,?

Question

where is the room coming from and what is in front of the expansion ? This question is hard to explain, hopefully someone will have the answer. Thanks

This question really bothers me, in a way its scary.

Perhaps, I did not get the ' 186,000' Light Years, part correct, I'm sorry.

Answer 1

It's not comming from anywhere. There isn't 'more room' involved.

The reason you're confused is that the universe isn't expanding in the way you think it is. It's not expanding from the inside out, like a baloon, and it's it's borders aren't continuously gaining more ground, like an explosion.

The expansion if the Universe is something called 'metric' expansion. This means that the spaces between things that already exist are getting larger. Imagine a peice of rubber. Draw two dots on the peice of rubber. We'll call the first one The Milky Way and the second one Andromeda. Now stretch it. The distance between the two becomes greater, along with the rest of the peice of rubber. There isn't anything adding anymore rubber. The dots themselves will also expand, though more slightly, because there's less space being expanded.

This is sort of similar to what the universe is doing, but in all directions. 186 thousand lightyears a day may sound like a lot, but when you spread that distance evenly across the entire univese, it becomes a lot less noticeable.

sorry but space is not expanding at 186,000 light years per day if that where true than matter can go faster than the speed of light a light year means just that 365 days is the didstance light travels . the expansion is an error in the big bang myth based on what stars they used to measure their rate of seporration but there not all seporationg in fact some collide wich means they have two different points of origin in their travels in the big bang all matter goes out from a central pointand would not collide with other matterwith out a major force causing a galixy to turn or change direction as to collide in the first place the time line for such an event would be billions of billions of light years and the universe would be much older than 13.8 billion years old this does not mean that large cosmic explosions dont occur all over the universe at different times. the space is all ready there it is eternal and forever there only trying to say that the particles, planets stars and stuff they see in space are seporatingbut in fact some of it is coming together.

Where did you pull that number from? The universe is expanding at the rate of about 70 km/s/Mpc (kilometers per second, per megaparsec) But that is the fabric of space/time. It is not creating new stars and planets as it goes, the existing ones are expanding out with it. Now, I don't know if the quantum foam density is changing, so we may be getting more quantum foam than before. Your football team will lose tomorrow. There is a reason, but it is ineffable. Edit: Guys, come on. Einstein said nothing about any limit on how the universe expands. Once you have two objects about 14 billion light years apart then, if the Hubble constant is right, they are moving apart at 1c. Given that we can see about 20 billion light years in all directions that means that the objects that we can see in opposite directions are moving apart at about 3c.

Answer 4

From what I remember, 5% of the the matter in the universe is baryonic. That's you, me, and all normal matter. The other 95% is dark matter. Basically, its only a theory as we can't prove it exists.

Although I have another question, wouldn't it be only a theory that space is expanding that fast. That's 669,600,000 times the speed of light if the theory is correct. If the universe was ending, according to what I've heard we'd never know so how do we know its expanding.

Answer 5

Whoa ! Where did that number come from ?? It's way too big. We're talking kilometers per second for expansion and not something zillions times faster than light. No one can really answer what it's expanding into. We have measurements that say it's expanding and that's about it. There is no honest right answer at the present.

Answer 6

One problem with your hypothesis...
186,000 is the speed of light in miles per second...
not the rate of the expanding universe.

Answer 7

186,000 Light years a day!
doesnt it sound a bit too fast? faster than the speed of light?
well, if space is really expanding that fast, then I think Einstein will yell from his grave "NO! NO! THIS IS NOT POSSIBLE! NOTHING CAN GO FASTER THAN LIGHT! NO WAY......"

THINK ABOUT IT.
do u really wanna disgrace einstein?

Answer 8

Science simply doesn't know. They generally insist that there is nothing that we are expanding into, it's a topology thing. we have no way to understand what is outside our universe as we have absolutely no interaction with it.

Answer 9

i am deffinitley no expert but i do know a bit, from what i understand i am to speculate that what space does it's borders keep pushing making nothing into space because space is inna sense nothing it is infinite, and i believe it literally just eats more space constantly... just a theory though

Answer 10

its 186,000 light years per second! Science dosent know yet.
