The number of atoms in the universe = approx 10^78. So no. The number of grains of sand must therefore be smaller than 10^78

No.
There are about 120 billion (1.2x10^11) gallaxies in the universe, each with approximately 100 billion stars (for large spiral galaxies like ours) each. The total would be about 1.2 x 10^22 stars. The mass of the average star would be about 2 x 10^30 kg (the total mass of all the planets and rocks around a solar system is only a fraction of the mass of its sun), so the mass of the "rocky" universe if its matter was chilled solid would be 2.4x10^52kg. Grains of sand can vary from very course to ultra-fine dust-like powder about 10^-8 kg each. So this makes the universe equal to 2.4x10^60 grains of ultra-fine sand. Another way to look a this is that it takes about 6x10^26 atoms of hydrogen to make 1 kg, so 2.4x10^52 kg is about 1.2x10^78 atoms of hydrogen.
Either way, that is many orders below 10^103.
I would say "No".

i guess it would.
one good reason i can give is that we r not sure of the number of planets in this entire universe,there r many planets being discovered & there r yet many more out there in this vast universe
may be the planets alone sum upto a 100 million or so--who knows??
so all the sand on these planets can exceed the number 2.7 x 10^103!

No. There aren't even that many atoms in the universe.
