This is something that a lot of people wonder about from time to time. Many people have different theories as to what it is like in heaven.

The Lord's Prayer says: 

Our Father in heaven,

hallowed be your name,
your kingdom come,
your will be done,
on earth as in heaven.
Give us today our daily bread.
Forgive us our sins
as we forgive those who sin against us.
Save us from the time of trial
and deliver us from evil.
For the kingdom, the power, and the glory are yours
now and for ever. Amen.

On earth as it is in heaven... I personally believe that means that when we are called home by our father, it will be like it is on earth, but with a couple added bonuses. Bonuses such as no more illness and no more war. 

God's word preached to us through his one and only son teaches us what Heaven is like, all we have to do is read it and believe. I believe that Heaven is Real and that when I am called home, I will go to Heaven.
