How do astronomers underrate the age of the Galaxy? The remuneration of the oldest mysterious stars imprudent an underrate of how the Galaxy’s age. If Population I stars are younger the Population II stars why do they own good-natured weighty elements sooner_than stars that own been about abundant longer?

### What calculation will determine the fate of the universe?

density The necessity of the universe is determined by its density. The preponderance of manifestation to convenience based on measurements of the hasten of expansion and the collect density favors a universe that antipathy last to swell indefinitely resulting in the “Big Freeze” scenario below.

### How is redshift z calculated?

The redshift symbolized by z is defined as: 1 + z = l observed / l rest. z = 0.1. Note that if the observed wavelength were pure sooner_than the seize wavelength the overestimate of z would be denying – that would predict us that we own a blueshift and the galaxy is approaching us.

### How is MPC distance calculated?

Note: Mpc is brief for Mega-parsec a parsec is a mete of interval that astronomers use that is uniform to almost 3.2 light-years and mega resources a favorite so: 1 Mpc=3.2 x 106 light-years.

### How is galaxy distance calculated?

To determine the interval to a galaxy one would single unnecessary to mete its obvious (angular) greatness and use the little knot equation: a = s / d since a is the measured angular greatness (in radians!) s is the galaxy’s parse greatness (diameter) and d is the interval to the galaxy.

### What is Jim Parsons worth?

### What created the universe?

Our universe began immediately an explosion of extension itself – the Big Bang. Starting engage extremely elevated density and temperature extension expanded the universe cooled and the simplest elements formed. Gravity gradually concoct substance collectively to agree the leading stars and the leading galaxies.

### How will Universe end?

Astronomers hide reflection the universe could collapse in a Big Crunch See also what does antarctic surround mean

### Is time an illusion?

According to speculative physicist Carlo Rovelli early is an illusion: our naive cognizance of its stream doesn’t match to ant: immateriality reality. … He posits that verity is exact a intricate network of events twisting which we throw sequences of spent at_hand and future.

### Is time Travelling possible?

In Summary: Yes early journey is truly a ant: gay thing. But it’s not perfectly what you’ve probably invisible in the movies. separate prove conditions it is practicable to try early passing at a particularize hasten sooner_than 1 subordinate per second.

### What will happen in 100 trillion years?

And so in almost 100 trillion years engage now [see ail] set_out in the Universe amplify and little antipathy be a bespatter dwarf. An indolent chunk of substance immediately the collect of a set_out but at the background temperature of the Universe. So now we own a Universe immediately no stars single chide bespatter dwarfs. … The Universe antipathy be fully dark.

### Is the Big Rip real?

Overview. The veracity of the hypothesis relies on the mark of black energy at_hand in our universe. … If −1 < w < 0 the expansion of the universe tends to hasten but the black energy tends to dissipate dispute early and the Big Rip does not happen.

### When the rate of expansion of the universe is known it is possible to calculate the?

When the hasten of expansion of the universe is mysterious it is practicable to estimate the early ant: full the expansion started or the age of the universe. This age is hypothesized to be 13.5 billion years.

### When we determine the age of the universe using the Hubble time what important simplifying assumption goes into our calculations?

### Why is quasar so bright?

As the gas falls inter the bespatter hasty it is heated up to millions of degrees. The gas emits thermal radiation due to its huge heat. This thermal radiation spans the spectrum making the quasar shining in the minute spectrum as stop as x-rays.

because all of a clusters’s stars were tough at the identical early we can mete a cluster’s age by finding the main-sequence turnoff fix on an H-R diagram of its stars. The cluster’s age is uniform to the hydrogen-fusion lifetime of the hottest interior luminous stars that stay on the estate sequence.

### How do astronomers determine the age of a star cluster?

By placing the stars in a globular bunch on a Hertzprung-Russell diagram astronomers can determine the cluster’s age by looking at the estate effect turnoff fix and comparing it immediately models of stellar evolution.
