Several people helped in this, but the main credit usually goes to Edwin Hubble.
Scientists determined that the object was expanding by analyzing its light spectrum using a spectrograph. By observing the Doppler shift in the spectral lines, scientists could infer the motion of the object relative to Earth, leading to the conclusion that it was moving away and expanding.
The answer is not determinable both because scientists have not determined the exact volume of the universe and because the universe is always expanding.
This question has been giving nightmares to cosmologists for years.But with the current evidences, scientists have determined that the universe is expanding at an ever-increasing rate and it will expand forever.
The universe is expanding.
It is because the Universe is expanding.
All the available evidence strongly indicates that the Universe is, indeed, expanding.
...And the Ever Expanding Universe was created on 2009-07-14.
Edwin Hubble determined that the universe was expanding by observing the redshift of light from distant galaxies. He found that most galaxies exhibited a redshift, indicating they were moving away from Earth, and the farther away a galaxy was, the faster it appeared to be receding. This relationship, known as Hubble's Law, suggested that the universe is expanding uniformly, leading to the conclusion that it originated from a singular point in the Big Bang.
1. the universe continues to keep expanding 2. the universe slowly stops expanding 3. big crunch (basically the universe will stop expanding and fall back into itself)
It is not exactly expanding into anything. The galaxies are moving apart from each other, from which we can infer that the universe is expanding. Theoretically, this is a result of the Big Bang, in which the universe began when all matter was compacted into a very tiny sum, and then exploded apart in a very big bang, and as a result is still expanding today.
the universe is expanding continuously even right now as you read this little sentence I wrote.
Yes. The Universe is expanding.
