How long would it take the universe to double in size?

At an age of 37.6 billion years, the Universe will be 99.4\% dark energy, the expansion rate will be 55.4 km/s/Mpc, and now the Universe will be 400 billion light years in diameter. And now, every 12.2 billion years after that, the size of the Universe will double, with the expansion rate leveling off at 55.4 km/s/Mpc.

How many times did the universe double in size?

A period of the very early universe is considered to have undergone exponential inflation doubling in size continuously to result in a 1078 increase in size between 10−36 to 10−32 seconds after the big bang.

What would happen if everything doubled in size?

We know the law of conservation of mass : “Mass can neither be created nor be destroyed.” Hence, when the size of everything in the universe doubles, the volume of all the objects change and the mass remains constant. Therefore, density changes.

Does the universe keep getting bigger?

A brief recap: The universe is getting bigger every second. The space between galaxies is stretching, like dough rising in the oven. Hubble measurements suggest a faster expansion rate in the modern universe than expected, based on how the universe appeared more than 13 billion years ago.

What if Earth was smaller?

If the earth were much smaller, its molten iron core would have exhausted its heat and stopped producing a magnetic field. At which point the sun would have blasted the reduced earth’s atmosphere away (the atmosphere is less attached due to smaller mass).

How much larger is the universe than the observable universe?

By using Bayesian model averaging, which focuses on how likely a model is to be correct given the data, rather than asking how well the model itself fits the data. They found that the universe is at least 250 times larger than the observable universe, or at least 7 trillion light-years across.

How many light years away is the universe?

While the estimate of 92 billion light-years comes from the idea of a constant rate of inflation, many scientists think that the rate is slowing down. If the universe expanded at the speed of light during inflation, it should be 10^23, or 100 sextillion.

Why is the universe getting bigger and bigger?

The more distant Universe is less clumpy and more uniform, having had less time to form larger, more complicated structures that require more time for gravity’s effects to take place. The early, distant Universe was also hotter. The expanding Universe causes all the light that travels through the Universe to stretch in wavelength.

What is the size of the infinite universe?

A finite universe has a finite size that can be measured; this would be the case in a closed spherical universe. But an infinite universe has no size by definition. According to NASA, scientists know that the universe is flat with only about a 0.4 percent margin of error (as of 2013).
