The accelerating expansion of the universe is the observation that the expansion of the universe is such that the velocity at which a distant galaxy is receding from the observer is continuously increasing with time.. Hubble went on to discover the expanding universe where galaxies are rushing away from us, but it has long been known that M31 is moving toward the Milky Way at about 250,000 miles per hour.

The discovery led to the widespread acceptance of the idea that our Universe is dominated by a mysterious force called dark energy, and altered the standard model of cosmology forever. We know, for example, that the universe is still expanding even now, at an ever-accelerating rate.

Once scientists understood that the universe was expanding, they immediately realized that it would have been smaller in the past. In this explosion, about 15 billion years ago, all matter, energy, space, and time were created. Well, for a long time, we didn't know. Real Physics Has Some Mind-Bending Answers Science says the universe could be a hologram, a computer program, a black hole or a bubble—and there … How do scientists know that the universe is expanding? Such was the force of this explosion that, to this day, the Universe is still expanding. Wielding state-of-the-art technologies and techniques, a team of Clemson University astrophysicists has added a novel approach to quantifying one of the most fundamental laws of the universe. The expanding universe is finite in both time and space. He used the 100-inch telescope on Mount Wilson in California - at the time, …

So apart from an obvious no to the logical sense that currently prevails that tells you that the universe will expand infinitely. 41 minutes ago Astronomers know from observation that the universe is expanding and _back in time to predict what happened a long time ago.

The universe began, scientists believe, with every speck of its energy jammed into a very tiny point. This extremely dense point exploded with unimaginable force, creating matter and propelling it outward to make the billions of galaxies of our vast universe. At first, they didn't entirely trust the results. How do we know the universe is expanding? This point, later called the big bang, was the beginning of the universe as we understand it today.

Well the question itself is about ‘ifs and buts’. How do astronomers know the universe is expanding? Astrophysicists dubbed this … That is fast enough to travel from here to the moon in one hour. Why can’t there be an alternative explanation, say that all atoms are shrinking? Scientists say that the universe is either expanding or contracting, and something cannot expand or contract unless expanding or contracting to/from a … The matter they can see only make 10% of that galaxy and the rest is dark matter.
