What is the Universe expanding into..

That is "She" indeed - I should have taken the time to read your post more carefully!

P.S. I admire your enthusiasm for String Theory. Unfortunately, it may never be experimentally verifiable.

So, it's not really a theory, its just another one of those hypotheses. What would we have to talk about without them!! 😀

The Rasin Cake is about BB behaviour and not the Inflation. I have started to accept that the "creation" was perhaps a 2-stage process ;-)

Inflation: make room
Big Bang: fill room.

Happy friday ya' all!!

Big Bang: fill room.

Fill room, but not make boom! 😊

And a happy start of the weekend to you too.

A photon uses up all of its spacetime speed c in travelling through space, leaving none to travel through time.

Therefore, from a photon's perspective its passage from A to B would appear instantaneous.

Compute that! 🙂

I Have Tried To @ Least.. 🙂
And have thought about computed That, And to put another spin on it,, Would'nt that simply equate to the effects of Time Dialation,, so that From the Photon's perspective as you say the rest of us would appear to be Frozen in the time dimension (( it's Always SpaceTime in my head as the one would imply the other) And therefor there is no time.! and as you say the photon experiences NoNe Of It... 🙂

I guess this is she:

In this video she asks why gravity is so weak.

He He... 🙂
You mean as there of coarse have to be Air To make Bang, boom, Soundwaves, or whatever... 🙂

 

[Bonsai]

But why wouldn't a single objects IFOR change with acceleration?

The absolutely do. An objecg travelling on its own between two galaxies is still referenced to something even if it is 2 million light yrs distant. It’s just easier to conceptualise it if you think of two (or more) objects close together.

A little boom would be expected, no?

poof.... 🙂

🙂 Thanx Galu
Hey Would you look at that, i did not realize 🙂 and bing.com no less 🙂
I was frustrated when my altibox system changed, And they removed the ones with hardisk inside witch in my case was three times as Large as the original
i still have that hard-disk lying around with the recording of that Episode with her, but no way, as far as i have tryed to put the hard-disk in my PC at least...
And of Coarse A Nice Weekend To Ya All....
🙂

Hi TnT.. 🙂
Think about it, an explosion, boom, ShockWave, has have to have a medium to travel trough, like air, And since space is mostly Vacum, Then no boom, no shockwave... 🙂

So the Bang in Big Bang is a hoax 🙂 ?

Interesting...

However, unlike the photon, we are not travelling through space at speed c, a quota of our spacetime speed is used up travelling through time.

I don't think you can talk about time dilation from a photon's perspective.

Ethan does a great job of explaining how photons experience time:

Ha! Ha! 😊

I'll submit that the evidence for the Big Bang is overpowering, but any interpretation of what went before could be classed as a hoax!

Hi TnT... 🙂
Yes.!!
At least as far as the (as the word implye a loud) Bang.! PART, That i had a feeling was the part you was thinking About... 😎
You know the music we so much enjoy 🙂
is waves of sound traveling trough A medium Air ( water, rock, metal ) And so there was No Nothing / vacum.? And The Bang/Expansion Craeted it's own SpaceTime As It expanded.. 😎

Why Not.?
We even experince Time Dialation Because Of The Gravity Of earth Time Runs a minute bit faster for the people at, mmh let say the space station, And this was even Verified Sometime in the end of the ninety's When we Got Sophisticated enough Thecnology To measure The Effect.. 🙂

Only gravity can bend space and time . Take that other forces .

he he.. for sure not much to hear in Vacuum of Space..
Or One Could say that it all depends on / in what spectrum one can hear If one could hear say microwaves one would still hear the faint echoes of the big bang
Once ear Drums Would Probably Explode, All Liquids in ones Body Evaporate & freeze before you got to think or hear anything... 🙂

You write funny - so you fit this thread ;-D

Okay, what if it was the only object accelerating in space with no reference?
