Our universe through a wormhole

[Harry Costas]

Hello GreekTTC

Why do you say my posts are useless?
-------------------------------------------------------------

Infinitenow when someone uses 4 letter words, we say they talk in French.

-------------------------------------------------------------

When I give links out its only to add and give info to people who do not have or have not seen that info.

So if anybody wishes for me to express any point at anytime please let me know.
----------------------------------------------------------
AS for Wormholes I cannot see them working as a means of travelling from one spot in space to another.

please explain further what you want

You have stated it will eventually be possible to travel faster than light. Since that is in direct conflict with Special Relativity, which is considered to be a sound theory, and which has been validated to many decimal places, I wish to know which aspect of the theory you think is flawed. What error in the theory are we going to exploit that will allow us transluminal velocities?

If you have no particular aspect in mind then why are you stating as fact what is merely an unsubstantiated opinion?

That is the root of my question.

Hello Eclogite

If you are limited by the speed of light thats OK

But! gravity travels much faster and its gravity that will allow man to travel faster than the speed of light.

Also man has sent electric pulses at multiple speed of light.

"By using the oscilloscope to trace the pulse's strength and speed, the researchers confirmed they sent the signal's peak tunnelling through the cable at more than four billion kilometres per hour"

Through out history man has entrapped themselves with limited ideas.

Please cite the research that substantiates this claim.
The current view is that gravity is also limited to the speed of light. Simply stating the reverse does not make it so.

This is simply an example of negative group velocity tunneling. Information is not transmitted at transluminal speeds. Relativity is not compromised. The prospects of FTL travel do not improve on the basis of this experiment.

One could say with equal, or more, accuracy and vigour: throughout history man has wasted energy and time by believing what he wanted to believe, not what was supported by evidence.

Hello All

If you want to confirm the speed of gravity read the following link
quote:
"Conclusion: The Speed of Gravity is ³ 2x1010 c
We conclude that gravitational fields, even “static” ones, continually regenerate through entities that must propagate at some very high speed, . We call this the speed of gravity. Equation [1] then tells us how orbits will expand in response to this large but finite propagation speed, since the field itself, and not merely changes in the field, will transfer momentum to orbiting target bodies. Rewriting equation [1] in a form suitable for comparisons with observations, we derive:

[5]

For the Earth’s orbit, = 1 year, = 10-4, and we take as an upper limit to the value 2.4x10-12/year (derived from ½ ) in solutions using radar ranging and spacecraft data (Pitjeva, 1993). Substituting these values, we get from Earth-orbit data that ³ 109 c.



Using the same equation with binary pulsar PSR1534+12 and the parameters in Table I, we can place the most stringent limit yet from the observed uncertainty in : ³ 2x1010 c.



A direct experimental verification in the laboratory that gravity propagates faster than light may now be possible. The protocol and preliminary results were reported in (Walker, 1997).



It might be tempting to conclude that the speed of gravity is infinite. But these limits on are still a long way from infinite velocity, and Newton’s statement, quoted at the beginning of this paper, still seems applicable. Infinite speeds, too, are acausal."

Eclogite let me know what you think of the link. I'm impressed by your thoughts.

I made some oops in my last post. Does not matter. Keep moving.

"But! gravity travels much faster and its gravity that will allow man to travel faster than the speed of light"

I should have said

Gravity travels faster than light and its gravity that will allow man to travel faster than the speed of light. It maybe a dream.

Another plea for documentation here.

Did you read the entire article=

And throughout history people have ignored the facts that are laid in front of them.

Hello All

Link on speed of gravity

somehow the link was deleted when I copy /paste.
Here it is

Good. Notice that the article is old and a lot of stuff has happened since then.

For example this:

First speed of gravity measurement revealed
http://www.newscientist.com/article.ns?id=dn3232

The ideas from the Meta Research are *theories* and as such they are good reading but a theory remains a theory until the predictions are proven.

And as of now, the measurements show that Einstein's prediction that the speed of gravity is the same as the speed of light (at least in a vacuum) is correct.

Hello Tormod

Thank you again

Ok,,,,,,,,,,,,,i have homework

Now I must go an pick up the kids
