![]() ![]() The balloon can inflate faster than this.ĭon’t yell at me! I am just telling you what the Astronomers say! The light traveling between the universe dots can only go at light speed. As the balloon is blown up the galaxies (dots) all start separating. Again, this is not a violation of relativity. The speed of the expansion, is also INCREASING, and it may pass the speed of light as well. Eventually, every object will be too far from every other object, to be seen. The Universe is still expanding, and according to the current theories, it will likely keep on expanding forever. (This does NOT violate relativity, according to Cosmologist Alex Filipenko of U.C. This would mean an expansion, faster than the speed of light. The current thinking, is that at the time of the Big Bang, (13,700 million years ago) the Universe underwent INFLATION. It’s purpose was to save me having to write sheepishly back to an Astronomer and say “Well yes I did know that…)ĭoesn’t mean there isn’t something far, far beyond, our “visible universe” though. WE CANNOT SEE ANYTHING FURTHER THAN 13,700 MILLION LIGHT YEARS AWAY! (Actually because space itself is expanding we can see about 45,000 million light years but this gets complicated. It will take one trillion years for it to get here.īUT THE UNIVERSE IS ONLY 13,700 MILLION YEARS OLD!! The light from this sun is headed toward us at the speed of light. Say there is a star, one trillion light years away from Earth. So if I make a mistake, I WILL HEAR ABOUT IT! …and learn something new too!ġ3,700 Million years. A friend down the street works on Chandra (More on that in a moment). I live in Huntsville Alabama, and Marshall Space Flight Center is nearby. If I get this wrong a local Astronomer will correct me. Astronomers and Cosmologist now think that our Universe is so big as to be incomprehensible. ![]()
