why?one day, all will come to an end including our earth,galaxy,etc?

Well!!!!!!!!!

All that happens now is purely due to the enery transfer from higher state to lower state!!

The Universe was iniitially filled homogeneously and isotropically with an incredibly high energy density, huge temperatures and pressures, and was very rapidly expanding and cooling.It was a partcile infinetly small when compared to the entire universe now, but, with huge concentrated energy!!!

Due to the Big bang explosion, the Universe started growing exponentially. The Universe continues to grow in size and fall in temperature, hence the typical energy of each particle was decreasing.

Over a long period of time, the slightly denser regions of the nearly uniformly distributed matter gravitationally attracted nearby matter and thus grew even denser, forming gas clouds, stars, galaxies, and the other astronomical structures observable today.

Thus, all the present mass and matter were once forms of energy!!

Now, as the state continues, the energy content still gets reduced.

You may argue that "Energy and Mass can neither be created or destroyed. But, can be changed from one form to another"

It is true...

Hence, I rephrase " the USEFUL energy content still gets reduced."

Universe is an isolated system. hence, as per thermodynamic laws, its entropy goes on increasing irrespective of the activity (except adiabatic).

Increase in entropy implies increase in the degree of unavailable Energy!!

Thus, the useful energy is getting depleting and in due course of time, we may encounter the "Heat Death" of the universe!!

Thus, we are moving towards a state of entropy.

The heat death of the universe would be a universe in a state of absolute entropy, where energy and density are equally dispersed about the universe.

Hence, all the things occuring now are purely due to the transistions in energy to make it unavailable!!

P.S:

Think off!!

Crores of Questions are remaining in Y!A and still they pour in into laks/day.

All the undeleted Questions, which are never being referred remain as unavailable resource of energy- They consume power and remain idle.

Thus, they are unavailable!!

nothing to prove...

Enjoy every seconds..that`s all

வாழ்க்கை கவிதை வாசிப்போம்

வானமளவு யோசிப்போம்

மகிழ்ச்சி என்ற ஒன்றை மட்டும்

மூச்சு போலே சுவாசிப்போம்

so in-between time`la

பூக்களைப் பிரித்து புத்தகம் படி

புà��²à¯à®µà¯†à®³à®¿ கண்டால் முயல் போல் குதி

நடைபாதைக் கடையில் தேநீர் குடி

வெறும் கரையில் படுத்துக்கொண்டு விண்மீன் பார்

ஆசைக்கு ரெக்கைகட்டி கட்டவிழ்த்து ஆடவிடு

கையோடு கைசேர்த்து வானத்தையே தொட்டுவிடு

The time’s never end, but we are.

I try to live my life as happily as I can.

Sometimes I think that we should live like there is no tomorrow and enjoy every second while we still can.

The time’s never end, but we are..so don`t hate others..

வழிகின்ற கண்ணீரில் இனம் இல்லையே

உதிரத்தின் நிறம் இங்கு வேறில்லையே

காற்றுக்கு திசை இல்லை தேசம் இல்லை

மனதோடு மனம் சேரட்டும்

எப்போதும் பறவைகள் அழுவதில்லை

So Don't worry be happy...

Well of course all will come to an end one day. Nothing lasts forever. Life & death is the cycle of all things. It is a waste of the perishes little time we do have to worry about things we have no control over. Cherish The moment you do have with family, friends, & loves one, because you never know what the future holds.

Maybe for a pessimist for you.But for a die hard optimist like me,everything is endless.Maybe this

contradicts what I have stated in my profile,but I still stand by both my averments because it will be very difficult for me to explain my philosophy on life,which is not only unique but all mine own.But I

hope and wish that you realise the real you so that you can feel your inner power.Have a Marvelous Day.I most certainly am having it.

because everything we know ends, humans aren't capable of thinking that something has no ending. it is more than possible that there is no end to what we call the universe. just because all life ends on our earth does not mean that everything in our universe ends. there is no right answer to your question but there is the possibility that there is no ending.

As George Harrison said, all things must pass.

it just will thats life all nice and happy and then just like that ur dead thats why you never take life for granted or err you shouldet at least

Everything that had a beginning will have an end.

The universe is finite.

if u realise this then nothing to worry. at the end "nothing"
