In summary: Anyways, time dilation is a result of the fact that the observer is moving. If the observer is stationary, then time dilation would be the same for both the observer and the object. The acceleration of the universe would cause the time coordinate to move away from the stationary observer, causing time dilation.

I've just been thimking of some potenial problems with the "expanding universe" and its supposed acceleration.

Objects further away are traveling faster. Does this mean it is speeding up or was it oroginally traveling faster during the big bang, and that's why it's further away?

The age of the universe has become a confusing concept. Originally Hubble came up with 1.8 billion years, "how could the universe be younger than the earth?" by analysing the furthest objects and background radiation.
Well if the shell of our universe is speeding away at over half the speed of light then time will be slower there, thus it would AGE slower. So the age thing all seems to be getting kind of relative. The Universe could be younger than the Earth, Maybe it would be morte acurrate to look as close as we can and the Geoligists 4 billion years could be the age of the universe. Time will be moving at different speeds all through the universe. So how can we cogently ask how old the universe "really" is?

If we could find the original birth point of the big bang maybe there will be some old remnant matter there that could be age tested?

One test that could prove the acceleration of the universe practically without a doubt would be to develop super sensitive redshift spectrum detectors and see if we can indeed measure a change over time in the spectrum showing that the redshift is increasing.

Any Ideas Anyone?

Objects further away were originally traveling faster. The issue of acceleration is something different.

Time slowing down is not an intrinsic property of objects - it only happens relative to a particular reference frame. In cosmology the time coordinate is taken to be the proper time of the objects. This does lead to disagreement with the time dilation of special relativity, a disagreement which I try to point out is due to the choice of coordinate system, rather than being physically meaningful: http://www.chronon.org/Articles/stretchyspace.html

There is no such thing as the original birth point of the big bang - or rather every point in the universe could have that claim.

Chrono has a point with the birth place of the Big Bang. It would be like blowing up a balloon really big, tieing it off, and then having you locate the centre inside the balloon.

The aging slower concept you mentioned is intriguing. I have never thought of that before. :rolleyes:
 

1. What is the Big Bang theory and how does it relate to the Hubble telescope?

The Big Bang theory is a scientific explanation for the origin of the universe. It states that the universe began as a singularity and has been expanding ever since. The Hubble telescope has played a crucial role in supporting this theory by observing the cosmic microwave background radiation, which is believed to be a remnant of the Big Bang.

2. How does the Hubble telescope measure the age of the universe?

The Hubble telescope measures the age of the universe by observing the brightness and distance of distant galaxies. By measuring the redshift (shift in wavelength) of light from these galaxies, scientists can calculate the rate of expansion of the universe and estimate its age.

3. What is the acceleration mystery and how does Hubble help solve it?

The acceleration mystery refers to the observation that the expansion of the universe is accelerating, rather than slowing down as previously thought. This phenomenon is attributed to dark energy, a mysterious force that counteracts the effects of gravity. The Hubble telescope has provided valuable data on the expansion rate of the universe, helping scientists better understand the role of dark energy in this acceleration.

4. How has the Hubble telescope improved our understanding of the universe?

The Hubble telescope has greatly advanced our understanding of the universe by providing high-resolution images of distant galaxies, stars, and other celestial objects. It has also helped scientists study the expansion and age of the universe, the formation of galaxies, and the composition of the universe. The data and images collected by Hubble have led to numerous discoveries and advancements in our knowledge of the cosmos.

5. What are the future plans for the Hubble telescope and its research?

The Hubble telescope is expected to continue operating until the mid-2020s, after which it will be replaced by the James Webb Space Telescope. In the meantime, Hubble will continue to provide valuable data and images to help scientists study the universe. Its research will focus on further understanding the expansion of the universe, the role of dark energy, and the formation of galaxies and stars.
