So, what happens in the heat death is that, 100 billion years from now, the universe will have expanded so much so quickly that we will not be able to see distant galaxies anymore. Our most powerful telescopes, when they look out into a dark part of the sky, will see nothing but darkness.25-Dec-2020

What would the heat death of the universe look like?
3:336:38How ‘heat death’ will destroy the universe | Katie Mack | Big ThinkYouTubeStart of suggested clipEnd of suggested clipThe heat death is sometimes called the big freeze. It's a very cold ending of the universe inMoreThe heat death is sometimes called the big freeze. It's a very cold ending of the universe in physics when we use the term heat we mean something very specific there we mean disordered.
Is the heat death of the universe possible?
In a hypothesized "open" or "flat" universe that continues expanding indefinitely, either a heat death or a Big Rip is expected to eventually occur. If the cosmological constant is zero, the universe will approach absolute zero temperature over a very long timescale.
How long before the universe has heat death?
This is the timeline of the Universe from Big Bang to Heat Death scenario. The different eras of the universe are shown. The heat death will occur in around 1.7×10106 years, if protons decay.
What comes after the heat death of the universe?
Physicist: If you wait forever, then you might see something happen. But the more practical answer is: no. The universe does a lot of stuff (for example, whatever you did today), but literally everything that ever happens increases entropy.
What will happen in trillion years?
It is expected that between 1011 (100 billion) and 1012 (1 trillion) years from now, their orbits will decay and the entire Local Group will merge into one large galaxy.
Will the universe stop expanding?
If the Universe holds enough matter, including dark matter, the combined gravitational attraction of everything will gradually halt this expansion and precipitate the ultimate collapse. Over time, galaxies, then individual stars, will smash into each other more frequently, killing off any life on nearby planets.
Is there a multiverse?
Our universe is but one in an unimaginably massive ocean of universes called … the multiverse. If that concept isn't enough to get your head around, physics describes different kinds of multiverse. The easiest one to comprehend is called the cosmological multiverse.
Is the universe getting hotter or colder?
It found that the mean temperature of gas across the universe has increased more than 10 times over that time period and reached about 2 million degrees Kelvin today — approximately 4 million degrees Fahrenheit. The universe is getting hotter, a new study has found.
How many years until the universe ends?
According to the formulas used to calculate cutoffs, a universe that is 13.7 billion years old will reach its cutoff in about 5 billion years, his team concludes. For most people, the idea that a mathematical tool could be elevated to a real-world event might seem strange, but there are precedents for it in physics.
