Physics, Astronomy & Cosmology / Are virtual particles exclusively virtual, or do some exist in reality too?

« on: 03/10/2012 05:45:31 »

Hi.

I understood from a previous answer that virtual photons are a mathematical tool/description, but has no real existence.

Is it the same for all virtual particles, or do other virtual particles exist in reality?

Thanks,
Magnus

Physics, Astronomy & Cosmology / Does virtual photons exist?

« on: 22/09/2012 20:08:49 »

Hey,
red in a book (forgot which one) that they exist, that they can even be measured in giving an electron slightly more energy than i has by it self.
Now reading "the theory about almost everything", and they mean that the virtual photon is a "handy concept" but apart from this no one knows
if they exist....

Can anybody enlighten me?

Thanks Magnus

Physics, Astronomy & Cosmology / Is TIME only a perception?

« on: 27/07/2012 06:37:03 »

Think Aristoteles made this thought;

Is time something that we perceive as an effect of speed limit and consequently it would not exist without movement?

Different particles/energy's have different speed limits, this gives the consequence that things does not happen instantly, hence time is "there".
The speed limit is due to the fact that space has a density, or something that prevents infinite speed.
When you travel fast, the space is compressed and in a way giving higher density, means that the speed limit within that fast travel, will be reduced.
In a way you could also say that some part of the speed is already used in the travel, and less is left over for other activities.

The movement of a particle, for instance the decay of a free neutron, could depend on that there are a number - chain of internal activities that need
to be happening in order for the decay to happen. These are happening with the speed limit of each activity, summing up to 15 minutes. If you move the
neutron in higher overall speed, some of the speed limit is used - or density is greater, meaning that the speed limit for this internal processes are lower. 
Then the decay takes longer.

An observer is depending on internal processes in order to observe. If you move the observer with light speed, no speed is left over for the internal processes of
observing. Or - space is so compressed that speed limit is 0. Means that for the observer time stands still - or do not exist.

Gravitation and acceleration warps space and gives it higher concentration = lower speed limit.

This would mean that time as a perception does not exist at 300k/sec, and also not when everything is standing still.
Time as we define it would be a perception only and would not exist absolute.

I mix a bit here between speed limit - "used speed" and density of universe..... and I guess that all this has been tested and rejected since this is something
that probably was tested a few hundred years ago.....but would be interested to hear your thoughts.

Thanks,

Physics, Astronomy & Cosmology / Is the Universe flat?

« on: 25/07/2012 05:55:26 »

Hi again.

I have understood that the universe is flat and has been so since the time of the cosmic background radiation.
Different measurements are confirming this.

The shape of universe is depending on density, Omega, which then is 1.

BUT; I believe that the density of universe has to have been higher before, with more of the energy compressed into
smaller space, and in the future the density should be lower.....

How can then universe have been flat, and be flat?

Thanks
