We observe the universe with our various telescopes. Since light travels at a finite speed, it takes time for any light to travel from an object (say, a galaxy), to your telescope. Therefore, for any distant object, you are not seeing the object as it appears now, but as it appeared when the light left it.
For very distant objects this can be billions of years, and further back in time you look, the more different the universe appears. Beyond about 13 billion years, there are no galaxies, for example.
Mainly that galaxies that are very far away (i.e., from the distant past) look different to galaxies that are near-by (from the more recent past).
All the available evidence strongly indicates that the Universe is, indeed, expanding.
It is not so much that the universe is expanding, but rather the rationalization for its expansion that provides evidence to support the Big Bang Theory. The Big Bang supports interpreted observational evidence of the Cosmic Microwave Background Radiation (CMBR) barrier that there is an evolutionary expansion of the universe which promotes a finite age for the universe.
Rock evidence refers to the geological clues that help scientists understand Earth's history, such as how different rock layers were formed, what types of organisms lived in the past, and how the Earth's surface has changed over time. By studying rock evidence, scientists can reconstruct past environments and events that have shaped the planet.

Scientist speculate there may be theoretically, but there is no evidence that there is any universe other than this one.
Different dimensions of time, such as past, present, and future, play a crucial role in shaping the evolution of the universe. The concept of time allows for the progression of events and changes in the universe over vast periods. The past influences the present state of the universe, while the future holds potential for further evolution and development. Time is a fundamental aspect of understanding how the universe has evolved and continues to change over time.
Coal is evidence of past plant life.
That is a theory that, while the Universe expands, new matter is created (at a very slow rate); the final result is that the Universe looks the same today as in the past. This is an alternative to the Big Bang theory (while acknowledging the expansion of the Universe); however, it contradicts more recent observations. In the past, the Universe was indeed quite different from today.
Most scientists that contributed to biology were of the past, and the only evidence of evolution is in the past. History is a completely different aspect, though, and has little to do with biology.
Archaeological evidence can include artifacts (objects made by humans), ecofacts (natural materials used or modified by humans), features (non-portable structures or remains), and sites (locations where evidence of past human activity is found). These different types of evidence help archaeologists piece together information about past cultures and societies.

According to Einstein (although it sounds a bit far fetched and plain out 'weird' this Universe is constantly doubling into new universes every single millisecond, meaning that every new universe is therefore NEW and there for on the day of initial coming into creation. Each Universe (says Einstein) is identical and their occurances are identical, and everything that happens in one Universe will happen in the other (but they cannot effect each other).That's where Time Travel comes into play... Einstein say the Universe was created (not saying how) and a millisecond later a new Universe was born, 1 millisecond behind the first. Now, he doesn't say weather every universe splits every millisecond, he just this one. So, if we want to get ten millisecond into the past, we have to go to Universe number ten. In that sense, we cannot go to the future because this universe is the furthest yet. The future (says I) doesn't exist. Also, this removes the chances of time paradoxes (the act of changing the present by doing something in the past and all). If you somehow enter a different Universe an kill your dad before you were born, THAT Universe's future is changed and different from this one's.However Einstein no sense in his explanation of how to get to an alternate or parallel Universe (something about copying every detail of yourself and this disintegrating and then passing through a foam cube or something and being re created as a replication of your in a different Universe.

Currently, scientific evidence suggests that the universe is expanding rather than contracting.
