Chemistry / Re: Will the release of a gas from a chemical reaction stop at a certain pressure?

« on: 24/10/2016 18:35:58 »

Thanks for the Answer im glad it sounds oversimplified to you haha.

As pressure increases im guessing that the temperature would rise also so would the melting point of the container also come into play here?

Chemistry / Will the release of a gas from a chemical reaction stop at a certain pressure?

« on: 24/10/2016 16:19:27 »

If a chemical reaction takes place within a closed container and a gas is produced the pressure inside will rise as far as I know until the reaction ceases or the container breaks and releases the pressure.

My question is that if you made a container thick enough would the reaction eventually stop because there would be no further room for gas to fit or is it irrelevant and that the gas would just keep being produced creating higher and higher pressure until the reaction stopped?

Physics, Astronomy & Cosmology / Re: Does a black hole really compress things down to a singularity?

« on: 24/03/2016 17:05:11 »

Quoteand so instead of it getting more compact it moves either slightly ahead/behind of time relative to the outside of the event horizon so that it is there in the galaxy but that it could for example be 1 second ahead of the galaxies timeframe and continually be behind or ahead of it?If it were behind our time by 1 second, you would already see it before the object crossed the event horizon. But then would you see 2 of them, and 3...? I don't think this can occur, as it involves creating mass out of nothing!If it was ahead in time by 1 second, you would just need to wait 1 second, and then you would see it, so it's not hidden by the event horizon.What happens inside an event horizon is a mystery. But for normal black holes, the fact that the escape velocity exceeds c means that almost nothing comes out, ie we don't know what goes on inside.

The reference to a second was just an example it could literally be any time just after that which is perceived within the galaxy. You say that after one second we would then see it as we had caught up with it, but what im trying to say here is that by that point the matter which could not be compressed anymore will be a second further on in time continuously so as we would never catch up with it. Sharing the same point in space but at a different time.

Physics, Astronomy & Cosmology / Does a black hole really compress things down to a singularity?

« on: 23/03/2016 15:45:32 »

Is the event horizon of a black hole not just the point at which matter cannot be crushed down any further? and that after that point something has to give and so instead of it getting more compact it moves either slightly ahead/behind of time relative to the outside of the event horizon so that it is there in the galaxy but that it could for example be 1 second ahead of the galaxies timeframe and continually be behind or ahead of it? but still at the same time allowing gravity to radiate like a left over wave from it being slightly ahead/behind.

* It would give a reason why you could not see the black hole.
* It could give the cause for galaxy rotation being the same on the outside as the inside.
* It could be why particles come into and out of existence as they move back into the galaxies timeframe for a moment.
* It would be a good candidate for dark matter maybe?
* A similar process could be responsible for the inflation period after the big bang?

I know this is looking like a theory but its more questioning really of where I may be going off the beaten track but it would be interesting to see what you guys think.

Physics, Astronomy & Cosmology / Why does the universe have to be expanding?

« on: 25/12/2015 14:31:13 »

Is it possible that the universe is already at a set size and that everything is just expanding out to its edge instead of the universe coming from a point at the big bang? If the edge had mass would this not explain how the matter in the universe is accelerating? as the gravitational effect grew as it gets closer.

Physics, Astronomy & Cosmology / Where do astronomers look for signals from E.T's?

« on: 27/09/2015 12:57:15 »

My point is do we look directly away from our sun? As any intelligent lifeforms using the transit method of detecting planets would find us easier if we went directly accross our star.

Physics, Astronomy & Cosmology / Re: Centre of the Universe?

« on: 27/09/2015 12:51:34 »

the fourth dimension or time has a center which would be at the start of time id say.

Wouldn't that apply only if time progressed in every direction from the start?

Isnt it the case that space and time are combined as spacetime which id assume means if space moves out in all directions then time does also.

Although there is no center in relation to the visual 3 dimensions we see, the fourth dimension or time has a center which would be at the start of time id say.

From what ive heard galaxies are "generally" proportioned in relation to there black hole at the center. Has anybody ever theorised that we may be on the inside rather than the outside? Im imagining some reversed donut type shape.

Physics, Astronomy & Cosmology / Do gravitons exist, and how we can we detect them?

« on: 27/08/2015 15:51:07 »

Is it known weather Gravitons exist or are just a theoretical? and if it is theoretical could you not use the height of the tides as an experiment to detect them? When the Moon is above the sea it directly affects the height of the tide whereas when its the opposite side of the Earth it has to work through the mass of the Earth and so could you see a lower tide as some of the Gravitons were absorbed by the Earths mass in a similar way to how they try to detect dark matter deep under ground.

Physics, Astronomy & Cosmology / Is gravity very weak because its been stretched out?

« on: 29/03/2014 15:02:52 »

If such as matter there was so much to start with was gravity the same?

How accurately can gravity be measured? Is it to many decimal places?

If we could measure it accurately enough would we see it getting weaker as the universe expands and also be able to measure the speed that it is expanding?

Physics, Astronomy & Cosmology / Are there large blocks of ice in space?

« on: 24/03/2014 11:19:58 »

Are there blocks of water ice in space that would be so large that they would be liquid inside because of the pressure of gravity?

Im basing this on how as you go deeper into the Earth the temperature rises.

If this was a ball of ice the size of the Earth, maybe it would be froze solid on the surface, then maybe a few miles down be luke warm water rite down to a core that was superheated and uninhabitable but in that band there could be life maybe? and a nursery for life that could come to Earth as the outer shell burnt of in the atmosphere protect the life within.

Is this a possible idea?

Physics, Astronomy & Cosmology / Re: Is Venus always going to be as inhospitable?

« on: 24/03/2014 11:10:38 »

I don't really like all this cloud life business anything larger than a few cells and it would most likely plumit to its crushing death.  Id say an important thing which hasn't been mentioned is water. Is there much on the planet we know of? I heard there was a lot of h2so4. Id say you would need water to be able to pull through the volcanic green house environment that's there currently and that isn't going to happen with a surface temperature that could melt lead.

As for the next thousand years or so id say we will be able to do some mind blowing things let alone inhabit Venus.

Id say your rite flr, planets will most likely be more like builders yards than home.

Thanks for your answers guys.

Physics, Astronomy & Cosmology / Re: Did the laws of physics exist before the big bang.

« on: 23/03/2014 19:50:19 »

There may have been nothing before the big bang but nothing refers to this universe we are in, what lies outside it nobody can currently know.

I believe the laws of physics are standard personally. Its like saying 2+2 isnt 4 no matter what universe your in that cannot change. I think the answer to everything lies in maths and the universe we live in is basically a mathmatical model.

Physics, Astronomy & Cosmology / Is Venus always going to be as inhospitable?

« on: 23/03/2014 17:58:17 »

 have just watched a YouTube video about the earth going through a period of intense volcanic activity a few hundred million years ago which killed of most of life. Could it be that something similar is happening to Venus now and that in maybe a million years or so it could become like Earth?

 Also the estimations of temprature rise were quite low for Earth so does this mean scientists could be way out here as Venus’s ground temp is a lot higher than what the Earths was or does it merely show two totally different things happening and that I'm totally wrong?

A 1cm cube of matter compressed to black hole density would have the energy equivalent 1.29*10^38 Joules

So is it possible to work out how much room 1.29*10^38 of energy takes up?

Physics, Astronomy & Cosmology / Does matter turn to energy in a black hole?

« on: 01/03/2014 18:44:05 »

When it gets crushed down its hard to comprehend matter going to a singularity but as it has a close relationship with energy then would it need any space at all if it changed to energy?

Does energy take up any space? I.e how much energy could fit inside a 1 cm2 container?
